The principles of the inventive gastrointestinal treatment system and method of enhancing the absorption into the bloodstream of ingestible medicaments for treating an ailment of the gastrointestinal (GI) tract using the inventive gastrointestinal treatment system, may be better understood with reference to the drawings and the accompanying description.
Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangement of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments or of being practiced or carried out in various ways. Also, it is to be understood that the phraseology and terminology employed herein is for the purpose of description and should not be regarded as limiting.
For the purposes of this application, the term “subject” relates to a human.
For the purposes of this application, the term “vibrating ingestible capsule” relates to an ingestible capsule adapted to at least intermittently vibrate, for a cumulative duration of at least one minute, in accordance with a vibration protocol of the capsule.
For the purposes of this application, the term “vibrating agitation mechanism” refers to any type of mechanism that vibrates or causes elements in its vicinity to vibrate, including a vibration motor or engine and a pendulum.
For the purposes of this application, the term “intermittently activated vibrating agitation mechanism” refers to a vibration agitation mechanism that vibrates or causes elements in its vicinity to vibrate and is operative at certain times, and does not vibrate or cause elements in its vicinity to vibrate at other times, the activation times being selected by a control mechanism or other control unit controlling the vibration agitation mechanism.
For the purposes of this application, the term “vibration protocol” relates to a protocol specifying vibration parameters of an intermittently activated vibrating agitation mechanism of a vibrating ingestible capsule. Typically, the vibration protocol relates to an activation delay for initiating vibration (e.g., a duration between “initial” activation of the capsule and the first activation of the vibration agitation mechanism), a vibration rate (number of vibration cycles per hour), a vibration duration and a repose duration for each vibration cycle, a vibration frequency, an amount of force exerted by the vibrations, and the like.
For the purposes of this application, the term “treatment procedure” relates to parameters of a treatment utilizing vibrating ingestible capsules, which are typically defined by a treating physician or medical practitioner. For example, the treatment procedure may include the number of capsules to be taken within a specific time duration (e.g., 3 capsules per week, 2 capsules per day), the frequency at which capsules should be taken, the time of day at which capsules should be taken, whether the capsule should be taken with or without food, and the like.
For the purpose of this application, the term “treatment protocol” relates to all aspects of treatment of a subject with a vibrating ingestible capsule, and includes the treatment procedure as well as the vibration protocol to be used for treating the subject.
For the purpose of this application, the term “activation input” relates to an input received by a control mechanism or control mechanism of a vibrating ingestible capsule, which causes the control mechanism or control mechanism of the capsule to activate itself, so as to be able to process inputs and/or to control additional components of the capsule. The activation input may be received from an element forming part of the capsule, such as a sensor sensing specific conditions in which the capsule should be activated, or from a remote source, such as a remote control mechanism, for example by way of a signal transmitted to the capsule, magnetic field applied to the capsule, specific motion applied to the capsule, or any other type of input provided to the capsule from a remote source.
For the purpose of this application, a vibrating ingestible capsule is said to be in an “inoperative state” when the capsule is in a storage condition, intended to preserve the life of a battery thereof. In the inoperative state, components of the capsule which are intended to receive or to provide an activation input, such as specific sensors, transceivers, and/or timing mechanisms may be active at least to a minimal degree. However, in the inoperative state, no vibration takes place, and a control mechanism controlling vibration of the capsule is inactive.
For the purpose of this application, a vibrating ingestible capsule is said to be in an “operative state” when the control mechanism of the capsule is processing inputs and data, and can cause a vibrating agitation mechanism of the capsule to vibrate or cause elements in its vicinity to vibrate.
For the purpose of this application, an “ingestible medicament” is at least partially absorbable to the bloodstream from within the stomach, small intestine, and large intestine, and more typically, within the stomach or small intestine.
For the purpose of this application, the term “partially absorbable” is meant to include the possibility that the environment within the gastrointestinal tract (including acids, enzymes, etc. thereof) may chemically modify the ingested medicament in order to achieve the characteristic “partially absorbable”.
For the purpose of this application, an estimated absorption time may be determined as follows:
(i) ingestible medicaments that are absorbed in the stomach have an estimated absorption time within a range of 0.5 to 1.5 hours from the time of ingestion of the medicament;
(ii) ingestible medicaments that are absorbed in the small intestine have an estimated absorption time within a range of 1.0 to 5 hours from the time of ingestion of the medicament;
(iii) ingestible medicaments that are absorbed in both the stomach and the small intestine have an estimated absorption time within a range of 0.5 to 5 hours from the time of ingestion of the medicament;
(iv) ingestible medicaments that are absorbed in the large intestine have an estimated absorption time of at least 4 hours, and more typically, within a range of 4 to 30 hours, 6 to 30 hours, 6 to 20 hours, or 8 to 20 hours from the time of ingestion of the medicament.
The location within the GI tract at which the particular ingestible medicament is absorbed to the bloodstream may often be public knowledge. This location may be provided by, or known to, the manufacturer and/or distributor of the particular ingestible medicament. Alternatively or additionally, the location may be known to relevant medical practitioners, including doctors and pharmacists, and more particularly, to a medical practitioner of the subject.
For the purpose of this application, an actual absorption time may be determined from clinical data, in vivo or in vitro, according to accepted clinical procedures known to those of skill in the art. Since actual absorption is achieved over a period of time, the “actual absorption time” or “actual absorption time period” may be defined by the time period at which between 20% and 80% of the absorption occurs. In the absence of such data, the “actual absorption time” or “actual absorption time period” may be defined by determining the “peak” actual absorption time, and building a time period of up to 1 hour on each side of the peak time.
For the purpose of this application, the term “ailment of the GI tract” is meant to include chronic or acute constipation, or symptoms associated therewith.
For the purpose of this application, the term “ailment of the GI tract” is meant to include gastroparesis, or symptoms associated therewith.
For the purpose of this application, the term “ailment of the GI tract” is meant to include Crohn's disease, or symptoms associated therewith.
For the purpose of this application, the term “ailment of the GI tract” is meant to include chronic or acute diarrhea, or symptoms associated therewith.
For the purpose of this application, the term “ailment of the GI tract” is meant to include colitis, or symptoms associated therewith.
For the purpose of this application, the term “ailment of the GI tract” is meant to include dyspepsia or dysphagia, or symptoms associated therewith.
For the purpose of this application, the term “ailment of the GI tract” is meant to include Hirschsprung's disease, or symptoms associated therewith.
For the purpose of this application, the term “ailment of the GI tract” is meant to include irritable bowel syndrome, or symptoms associated therewith.
For the purpose of this application, the term “ailment of the GI tract” is meant to include any disease in which the subject positively responds to an osmotic gastrointestinal treatment.
For the purpose of this application, the term “ailment of the GI tract” is meant to include any disease in which the particular subject positively responds to a stool softening treatment.

For the purpose of this application, the term “ailment of the GI tract” is meant to include any disease in which the subject positively responds to a GI fluid absorption inducing treatment.
For the purpose of this application, the term “managing a condition of”, with respect to an ailment of the GI tract, is meant to include, inter alia, improving absorption of a medicament, such as a medicament used in the treatment of the ailment of the GI tract (e.g., Linaclotide (Linzess®)), into the bloodstream. Such condition management may be manifested by at least one of (i) improved medicament efficacy due to the increased absorption; and (ii) reduced dosage of the medicament, due to the increased medicament absorption efficacy.

In some embodiments, system 100 further includes a control unit 120, which may be remote from capsule 101, and which is adapted to provide one or more inputs to the capsule. In some such embodiments, capsule 101 further includes a remote input receiving mechanism 116, functionally associated with control mechanism 106, and adapted to receive inputs from an input providing mechanism 122 of control unit 120.
In some embodiments, control unit 120 may further include a timing mechanism 126, adapted to track at least one time characteristic, such as a duration that has passed since a control instruction was provided to capsule 101.
In some embodiments, control unit 120 may further include a user input receiver 128, such as a keyboard, touch screen, or touch pad, adapted to receive input from a user, such as the subject, a medical professional treating the subject, or a caregiver of the subject.
Control unit 120 may be any suitable type of control unit. In some embodiments, control unit may be a suitably configured smart phone or a tablet computer.
In some such embodiments, control unit 120 may provide inputs to capsule 101 by remotely transmitting the inputs from input providing mechanism 122 to remote input receiving mechanism 116, for example using a short range wireless communication method, such as radio frequency (RF) communication or Bluetooth® communication. One example of such a mechanism for providing input to a capsule is described in U.S. patent application Ser. No. 15/132,039 filed Apr. 18, 2016 and entitled “IN VIVO DEVICE AND METHOD OF USING THE SAME”, which is incorporated by reference for all purposes as if fully set forth herein.
In some embodiments, control unit 120 is adapted to provide the activation input to control mechanism 106 of capsule 101. In some such embodiments, control unit 120 provides the activation input prior to the subject ingesting capsule 101, whereas in other embodiments control unit 120 provides the activation input following ingestion of capsule 101 by the subject.
Relating to the characteristics of vibrating agitation mechanism 104, the vibrating agitation mechanism may be any suitable mechanism that can be intermittently activated and can apply suitable forces onto capsule housing 102.
In some embodiments, intermittently activated vibrating agitation mechanism 104 may include a radial agitation mechanism adapted to exert radial forces on capsule housing 102, in a radial direction with respect to the longitudinal axis of housing 102. For example, the radial agitation mechanism may include an unbalanced weight attached to a shaft of an electric motor powered by said battery, substantially as described in U.S. Pat. No. 9,707,150, which is incorporated by reference for all purposes as if fully set forth herein.
In some embodiments, intermittently activated vibrating agitation mechanism 104 may include an axial agitation mechanism adapted to exert radial forces on the capsule housing 102, in an axial direction with respect to a longitudinal axis of housing 102. For example, the axial agitation mechanism may include an electric motor powered by the battery and an urging mechanism, associated with, and driven by, the electric motor, such that the urging mechanism adapted to exert said axial forces, substantially as described in U.S. Pat. No. 9,707,150. In some embodiments, the urging mechanism adapted to exert the axial forces in opposite directions. In some embodiments, the urging mechanism is adapted to deliver at least a portion of the axial forces in a knocking mode. In some embodiments, the forces exerted by intermittently activated vibrating agitation mechanism 104 on capsule housing 102 in the vibration mode of operation include radial forces in a radial direction with respect to the longitudinal axis of the housing and axial forces in an axial direction with respect to the longitudinal axis. In some embodiments, a single agitation mechanism exerts both the radial and the axial forces. In other embodiments, the axial forces are exerted by one agitation mechanism, and the radial forces are exerted by another, separate, agitation mechanism, where both agitation mechanisms form part of intermittently activated vibrating agitation mechanism 104.
In some embodiments, the intermittently activated vibrating agitation mechanism 104 may include a magnet mounted onto a rotor adapted to exert a magnetic field as well as radial forces on capsule housing 102. For example, such a magnetic vibration agitation mechanism is described in U.S. patent application Ser. No. 15/058,216 filed on Mar. 2, 2016 and entitled “PHYSIOTHERAPY DEVICE AND METHOD FOR CONTROLLING THE PHYSIOTHERAPY DEVICE”, which is incorporated by reference for all purposes as if fully set forth herein.
In some embodiments, housing 102 may include first and second members, and vibrating agitation mechanism 104 may include a mechanism adapted to effect a vibration by moving the first member of the housing in the opposite direction relative to the second member of the housing, substantially as described in U.S. Pat. No. 9,078,799, which is incorporated by reference for all purposes as if fully set forth herein.
In some embodiments, housing 102 may include a vibration agitation mechanism 104 which makes use of a pendulum to cause vibration in the vicinity of the capsule, for example as described in CN Patent Application Number 105997466 filed on Jun. 16, 2016 and entitled “INTELLIGENT VIBRATING ELECTRONIC CAPSULE”, which is incorporated by reference for all purposes as if fully set forth herein.
In the vibrating mode of operation, intermittently activated vibrating agitation mechanism 104 is adapted to have a plurality of vibration cycles, where each cycle includes a vibration duration followed by a repose duration. Forces are exerted by the vibrating agitation mechanism 104 on capsule housing 102 only during the vibration duration, and as such capsule housing 102 only exerts forces on an environment thereof during the vibration duration.
In some embodiments, the number of vibration cycles per hour is in the range of 20 to 400, 40 to 400, 60 to 400, 80 to 400, 40 to 380, 60 to 380, 80 to 380, 40 to 360, 60 to 360, 80 to 360, 100 to 360, 100 to 330, 100 to 300, 100 to 280, 100 to 250, 100 to 220, 100 to 200, 120 to 300, 120 to 280, 120 to 250, 120 to 220, 120 to 200, 150 to 300, 150 to 280, 150 to 250, 150 to 220, 150 to 200, 170 to 300, 170 to 250, 170 to 220, or 170 to 200.
In some embodiments, the repose duration is greater than the vibration duration.
In some embodiments, the vibration duration is in the range of 0.1 second to 10 seconds, 1 second to 10 seconds, 1 second to 9 seconds, 2 seconds to 9 seconds, 3 seconds to 9 seconds, 3 seconds to 8 seconds, 3 seconds to 7 seconds, 3 seconds to 6 seconds, or 4 seconds to 6 seconds.
In some embodiments, the repose duration is in the range of 1 second to 180 seconds, 3 seconds to 180 seconds, 5 seconds to 180 seconds, 5 seconds to 150 seconds, 5 seconds to 120 seconds, 8 seconds to 100 seconds, 8 seconds to 30 seconds, 10 seconds to 80 seconds, 10 seconds to 70 seconds, 10 seconds to 60 seconds, 10 seconds to 50 seconds, 10 seconds to 40 seconds, 10 seconds to 30 seconds, 10 seconds to 20 seconds, or 15 seconds to 20 seconds.
In some embodiments, the total duration of one vibration cycle is in the range of 1.1 seconds to 200 seconds, 5 seconds to 200 seconds, 10 seconds to 200 seconds, 10 seconds to 150 seconds, 10 seconds to 100 seconds, 10 seconds to 80 seconds, 10 seconds to 50 seconds, 10 seconds to 40 seconds, 10 seconds to 30 seconds, 15 seconds to 50 seconds, 15 seconds to 40 seconds, 15 seconds to 30 seconds, or 15 seconds to 25 seconds.
In some embodiments, the cumulative duration of the vibrating mode of operation, or the cumulative duration during which vibration cycles are occurring, is in the range of 1 hour to 12 hours, 2 hours to 10 hours, 2 hours to 8 hours, 2 hours to 6 hours, 2 hours to 4 hours, or 2 hours to 3 hours. It will be appreciated that the cumulative duration of vibration cycles may be dependent on properties of power source 108.
It will be appreciated by persons skilled in the art that the vibration mode of operation may be intermittent, or interrupted, such that vibrating agitation mechanism 104 is operative in the vibration mode for a first duration, for example 30 minutes, then does have any vibration cycles for a second duration, for example 1 hour, and then is operative in the vibration mode and has vibration cycles for a third duration, for example two hours. The cumulative duration relates to the sum of all durations during which vibrating agitation mechanism 104 was operative in the vibration mode and included vibration cycles, including the vibration duration and the repose duration of the vibration cycle.
In some embodiments, vibrating agitation mechanism 104 is configured to exert forces on the capsule housing 102, such that a net force exerted by the capsule housing 102 on the environment thereof is in the range of 50 grams force (gf) to 600 gf, 50 gf to 550 gf, 100 gf to 550 gf, 100 gf to 500 gf, 150 gf to 500 gf, 200 gf to 500 gf, or 200 gf to 450 gf.
In some embodiments, vibrating agitation mechanism 104 is configured to exert said forces on capsule housing 102 to attain a capsule housing 102 vibrational frequency within a range of 10 Hz to 650 Hz, 15 Hz to 600 Hz, 20 Hz to 550 Hz, 30 Hz to 550 Hz, 50 Hz to 500 Hz, 70 Hz to 500 Hz, 100 Hz to 500 Hz, 130 Hz to 500 Hz, or 150 Hz to 500 Hz.
It will be appreciated that the exact specifications of the capsule, such as the specific frequency and force ranges applicable to a specific capsule, are dependent on the specifications of the power source and of the vibrating agitation mechanism.
It will be further appreciated that a specific capsule may be controlled by the control mechanism such that different vibrational frequencies may be attained and/or different net forces may be exerted, by the capsule in different vibration cycles of the capsule. Due to the natural distinction between subjects, use of multiple different parameters in different vibration cycles of a single capsule would allow the capsule to successfully treat multiple subjects, even if the personal optimal treatment for those subjects is not the same, as there is a higher chance that in at least some of the vibration cycles the activation parameters of the capsule would reach, or be close to, the optimal parameters for each specific subject.
Control mechanism 106 is adapted to control the operation of intermittently activated vibrating agitation mechanism 104. Such control may include control of any one or more of the force applied by the vibrating agitation mechanism, the vibrational frequency reached, the times in which vibrating agitation mechanism 104 operates in the vibration mode of operation, the vibration duration of each vibration cycle, the repose duration of each vibration cycle, the vibration cycle duration, and cumulative vibration duration of the vibrating agitation mechanisms.
In some embodiments, control mechanism 106 is adapted to receive information relating to the desired vibration protocol from control unit 120, prior to ingestion of the capsule or to activation thereof, or during the capsule's traversal of the subject's GI tract.
For example, the information may be remotely transmitted from control unit 120 to control mechanism 106, for example using a short range wireless communication method. In some embodiments, the information is transmitted as a list of vibration parameters for effecting the vibration protocol. In some embodiments, the information is transmitted as executable code for effecting the first vibration protocol.
In some embodiments, the information includes a desired number of vibration cycles, a desired vibration duration in each vibration cycle, a desired repose duration in each vibration cycle, a desired cumulative vibration duration, and the like.
Control mechanism 106 may be adapted to control vibrating agitation mechanism 104 so that the capsule applies forces to an environment thereof, such that within the gastrointestinal tract, a mechanical stimulation of the wall of the gastrointestinal tract is effected.
Reference is now additionally made to
As seen at step 200, vibrating gastrointestinal capsule is provided. The vibrating gastrointestinal capsule may have, as described with respect to
At step 204, an ingestible medicament for treatment of an ailment of the GI tract is ingested by the subject.
The ingestible medicament for treatment of an ailment of the GI tract includes at least one of:
In some embodiments, the ingestible medicament may be ingested directly, for example by ingesting a tablet, capsule, liqui-gel capsule, chewable tablet, syrup, or any other form of dosage including the medicament.
In some embodiments, the ingestible medicament may be ingested within a medicament delivery capsule, adapted to deliver the medicament to a specific location in the gastrointestinal tract. Examples of such medicament delivery capsules are described in:
U.S. Pat. Nos. 5,170,801; 6,632,216; 6,776,165; 6,929,363; 8,202,697; 8,518,022; 8,597,278; and 8,771,730;
U.S. Patent Application Publication Numbers 2004/0253304; 2004/0267240; 2005/0058701; 2005/0148847; 2008/0275430; 2009/0306633; and 2010/0049012;
PCT Patent Application Publication Numbers WO2006/025013; WO2008/012700; and WO 2009/063375;
all of which are incorporated by reference for all purposes as if fully set forth herein. At step 206, the vibrating gastrointestinal capsule is ingested by the subject.
While the ingestible medicament and the vibrating gastrointestinal capsule may be ingested at the same time, or within 0-30 minutes of each other, no order of action is implied by
As shown, step 208A includes controlling at least one of a time of ingesting the vibrating gastrointestinal capsule and a timing of said vibration mode of operation (e.g., when the vibration mode is initiated, a duration of the vibration mode, etc.) to at least partially transpire within at an absorption time period of the ingestible medicament within the gastrointestinal tract of the subject. Typically, the absorption time period is an estimated absorption time period, as defined herein. In some cases, an actual absorption time period may be determined, again, as defined herein.
Additionally or alternatively, the method may include controlling at least one of a timing of ingesting the vibrating gastrointestinal capsule and a timing of said vibration mode of operation such that the vibration mode at least partially transpires within a particular time period with respect to the ingesting of the ingestible medicament (step 208B).
The particular time period may be within 5 hours, within 4 hours, within 3.5 hours, within 3 hours, or within 2.5 hours of the ingesting of the ingestible medicament, and more typically, within 2 hours, within 1.5 hours, within 1 hour, or within 0.5 hours thereof.
In some embodiments, the method may include controlling at least one of a timing of ingesting the vibrating gastrointestinal capsule and a timing of said vibration mode of operation such that said vibration mode at least partially transpires when the capsule is in a region of the gastrointestinal tract in which the medicament is typically absorbed into the bloodstream. The region of the gastrointestinal tract may include one or more of the stomach of the subject, the duodenum of the subject, the small intestine of the subject, the large intestine of the subject, or the colon of the subject.
For example, when cooperating with the medicament Linzess®, which is typically absorbed into the bloodstream through the stomach walls and/or the small intestine walls, the vibration mode at least partially transpires within a time period in which the capsule traverses, or is expected to traverse, the stomach and small intestine.
In some embodiments, and as described in further detail herein, the method may include transitioning the capsule (from an inoperative state) to an operative state.
The capsule may be pre-programmed with a vibration protocol. This protocol may include, by way of example, a particular or pre-determined activation time following ingestion, in which the capsule is transitioned from an inoperative state to an operative state.
Alternatively or additionally, the capsule may receive an activation input in an active fashion (e.g., from an external controller via RF) or in a passive fashion (e.g., a signal from a sensor to the on-board controller). It will be appreciated that step 202, in which the vibrating ingestible capsule is transitioned from the inoperative state to the operative state, may be performed after ingestion of the capsule by the subject (e.g., in the case of external control via RF).
In some embodiments, control mechanism 106 may optionally receive a desired vibration protocol for the subject, at an optional step 203.
In some embodiments, providing of the predetermined time(s) at step 202 and/or providing the desired vibration protocol for the subject at step 203 occurs at the time of manufacturing of the capsule, for example by pre-programming the time into the control mechanism.
In some embodiments, providing of the predetermined time(s) at step 202 and/or providing the desired vibration protocol for the subject at step 203 may be effected by a control unit, such as control unit 120 of
The programming of the vibration protocol may include remotely transmitting the desired vibration protocol from control unit 120 to control mechanism 106, for example using a short-range wireless communication method. In some embodiments, the desired vibration protocol is transmitted as a list of vibration parameters for effecting the vibration protocol. In some embodiments, the desired vibration protocol is transmitted as executable code for effecting the vibration protocol.
As discussed hereinabove, in some embodiments the activation input may be received from the control unit 120 or from sensors within the capsule sensing that the capsule has been ingested or that a user has carried out an activation motion with the capsule.
Substantially as described hereinabove, the vibrating ingestible capsule may be activated prior to the user ingesting the capsule at step 206, for example by a signal from the control unit or by the user carrying out an activation motion. In other embodiments, the activation input is provided at the time of ingestion or immediately thereafter, for example by sensors sensing a change in the environment of the capsule due to its ingestion, as described at length hereinabove. In yet other embodiments, the activation input may be provided remotely when the capsule is already in the body of the subject, for example by remote communication from control module 120.
Following activation of capsule 101, or together therewith, capsule 101 is ingested by the subject, and begins to travel through the gastrointestinal tract of the subject, as evident from step 206.
Operation of vibrating agitation mechanism 104 in the vibrating mode of operation at step 208A or 208B effects vibration of capsule housing 102, as described hereinabove, such that the housing exerts vibrations on the environment surrounding the capsule. Specifically, vibration of capsule housing 102 may be intended to effect a mechanical stimulation of the wall of the gastrointestinal tract at a time when the ingested medicament may be absorbed, thereby to increase or accelerate the absorption of the ingested medicament into the bloodstream of the subject, for delivery to a target treatment region of the medicament.
