Patent Grant
9526418
The United States Patent Office (USPTO) has published a notice to the effect that the USPTO's computer programs require that patent applicants reference both a serial number and indicate whether an application is a continuation or continuation-in-part. Stephen G. Kunin, Benefit of Prior-Filed Application, USPTO Official Gazette Mar. 18, 2003, available at http://www.uspto.gov/web/offices/com/sol/og/2003/week11/patbene.htm. The present Applicant Entity (hereinafter “Applicant”) has provided above a specific reference to the application(s) from which priority is being claimed as recited by statute. Applicant understands that the statute is unambiguous in its specific reference language and does not require either a serial number or any characterization, such as “continuation” or “continuation-in-part,” for claiming priority to U.S. patent applications. Notwithstanding the foregoing, Applicant understands that the USPTO's computer programs have certain data entry requirements, and hence Applicant is designating the present application as a continuation-in-part of its parent applications as set forth above, but expressly points out that such designations are not to be construed in any way as any type of commentary and/or admission as to whether or not the present application contains any new matter in addition to the matter of its parent application(s).
All subject matter of the Related Applications and of any and all parent, grandparent, great-grandparent, etc. applications of the Related Applications is incorporated herein by reference to the extent such subject matter is not inconsistent herewith.
Small scale generators for generating energy at levels suitable for powering devices which are in vivo or ex vivo to a human or animal are described. Such generators may be implanted in luminal structures so as to extract power from intraluminal pressure changes.
In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here.
The intraluminal generator 100 may include an integrated pressure change receiving structure 103A configured to receive a pressure change associated with a fluid pressure within the lumen 101. Alternately, the pressure change receiving structure 103 may be an external pressure change receiving structure 103B operably coupled to the intraluminal generator 100 via a coupling 104 to transfer a received pressure from the pressure change receiving structure 103B to the intraluminal generator 100 in a form which the intraluminal generator 100 may convert to energy.
The intraluminal power generation device may comprise an energy storage apparatus 105 for storage of energy generated by the intraluminal generator 100. The energy storage apparatus 105 may be operably coupled to the intraluminal generator 100 by a coupling 106.
The intraluminal power generation device may comprise a power utilization device 107 that may use energy generated by the intraluminal generator 100 and/or stored in the energy storage apparatus 105 to carry out a desired function. The power utilization device 107 may be operably coupled to the intraluminal generator 100 and/or an energy storage apparatus 105 by a coupling 108.
Referring to
A movement and/or deformation of the pressure change receiving structure 103 may be translated either directly (e.g. the intraluminal generator 100 comprises the pressure change receiving structure 103A) or indirectly (e.g. the pressure change receiving structure 103B is operably coupled to a generator) into energy either through the motion of the pressure change receiving structure 103 and/or the electrical properties of the materials comprising the pressure change receiving structure 103.

A chemical energy storage apparatus 105 may comprise a battery. The battery may comprise one or more voltaic cells. The battery may be a rechargeable battery such as a nickel cadmium (NiCd), nickel metal hydride (NiMH), lithium ion (Li-ion), and lithium ion polymer (Li-ion polymer) which may be charged by energy produced by the intraluminal generator 100.
A chemical energy storage apparatus 105 may comprise a fuel cell. The fuel cell may be selected from one or more of a metal hydride fuel cell, an electro-galvanic fuel cell, a direct formic acid fuel cell (DFAFC), a zinc-air fuel cell, a microbial fuel cell, an upflow microbial fuel cell (UMFC), a direct borohydride fuel cell, an alkaline fuel cell, a direct methanol fuel cell, a reformed methanol fuel cell, a direct formic acid fuel cell, proton exchange membrane fuel cell, an RFC—Redox fuel cell, a protonic ceramic fuel cell, a direct carbon fuel cell, a planar solid oxide fuel cell, and the like. The fuel cell may be a reversible fuel cell combined with an electrolyzer and a fuel storage apparatus to utilize an electrical current generated by the intraluminal generator 100 to generate fuel cell fuel components (e.g. oxygen and hydrogen) from a fuel cell product (e.g. water). The fuel cell fuel components may be stored in a fuel cell storage apparatus for later use in recovering energy from the fuel cell fuel components via the fuel cell.

Further, the one or more acoustical transmitters and acoustical receivers may be in resonance (e.g. an acoustical transmitter generates acoustical waves that are in phase with a movement of the acoustical receiver).
Still further, the one or more acoustical transmitters and acoustical receivers may be in resonance (e.g. an acoustical transmitter generates acoustical waves that are in phase with a movement of the acoustical receiver) where the Q factor of the acoustical transmitter and acoustical receiver is at least 10,000. A transmitter/receiver device may be such as described in “Tunable high-Q surface-acoustic-wave resonator” by Dmitriev, et al., Technical Physics, Volume 52, Number 8, August 2007, pp. 1061-1067(7); U.S. Patent Application Publication No. 20060044078, “Capacitive Vertical Silicon Bulk Acoustic Resonator” to Ayazi, et al.; “Acoustic Wave Generation and Detection in Non-Piezoelectric High-Q Resonators”, Lucklum, et al., Ultrasonics Symposium, 2006, October 2006, Pages: 1132-1135.

Further, a first intraluminal generator 100 and first energy storage apparatus 105 operably coupled by a first resonant inductive coupling 106 (as described above with respect to operation 1004) may be at least partially co-located with a second intraluminal generator 100 and second energy storage apparatus 105 operably coupled by a second resonant inductive coupling 106 within one or more anatomical structures. In order to avoid destructive interference between the first resonant inductive coupling 106 and the second inductive coupling 106, the waveguides associated with the first resonant inductive coupling 106 and the waveguides associated with the second inductive coupling 106 may be configured so as to be in mutual resonance.

The herein described subject matter may illustrate different components contained within, or connected with, different other components. It is to be understood that such depicted architectures are merely exemplary, and that in fact many other architectures can be implemented which achieve the same functionality. In a conceptual sense, any arrangement of components to achieve the same functionality is effectively “associated” such that the desired functionality is achieved. Hence, any two components herein combined to achieve a particular functionality can be seen as “associated with” each other such that the desired functionality is achieved, irrespective of architectures or intermedial components. Likewise, any two components so associated can also be viewed as being “operably connected,” or “operably coupled,” to each other to achieve the desired functionality, and any two components capable of being so associated can also be viewed as being “operably couplable,” to each other to achieve the desired functionality. Specific examples of operably couplable include but are not limited to physically mateable and/or physically interacting components and/or wirelessly interactable and/or wirelessly interacting components and/or logically interacting and/or logically interactable components.
While particular aspects of the present subject matter described herein have been shown and described, changes and modifications may be made without departing from the subject matter described herein and its broader aspects and, therefore, the appended claims are to encompass within their scope all such changes and modifications as are within the true spirit and scope of the subject matter described herein. Furthermore, it is to be understood that the invention is defined by the appended claims. In general, terms used herein, and especially in the appended claims (e.g., bodies of the appended claims) are generally intended as “open” terms (e.g., the term “including” should be interpreted as “including but not limited to,” the term “having” should be interpreted as “having at least,” the term “includes” should be interpreted as “includes but is not limited to,” etc.). If a specific number of an introduced claim recitation is intended, such an intent will be explicitly recited in the claim, and in the absence of such recitation no such intent is present. For example, as an aid to understanding, the following appended claims may contain usage of the introductory phrases “at least one” and “one or more” to introduce claim recitations. However, the use of such phrases should not be construed to imply that the introduction of a claim recitation by the indefinite articles “a” or “an” limits any particular claim containing such introduced claim recitation to inventions containing only one such recitation, even when the same claim includes the introductory phrases “one or more” or “at least one” and indefinite articles such as “a” or “an” (e.g., “a” and/or “an” should typically be interpreted to mean “at least one” or “one or more”); the same holds true for the use of definite articles used to introduce claim recitations. In addition, even if a specific number of an introduced claim recitation is explicitly recited, such recitation should typically be interpreted to mean at least the recited number (e.g., the bare recitation of “two recitations,” without other modifiers, typically means at least two recitations, or two or more recitations). Furthermore, in those instances where a convention analogous to “at least one of A, B, and C, etc.” is used, the convention (e.g., “a device having at least one of A, B, and C” would include but not be limited to devices that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). In those instances where a convention analogous to “at least one of A, B, or C, etc.” is used, in general such a construction is intended (e.g., “a device having at least one of A, B, or C” would include but not be limited to devices that have A alone, B alone, C alone, A and B together, A and C together, B and C together, and/or A, B, and C together, etc.). It will be further understood by those within the art that virtually any disjunctive word and/or phrase presenting two or more alternative terms, whether in the description, claims, or drawings, should be understood to contemplate the possibilities of including one of the terms, either of the terms, or both terms. For example, the phrase “A or B” will be understood to include the possibilities of “A” or “B” or “A and B.”
