Implantable electrical stimulation systems have proven therapeutic in a variety of diseases and disorders. For example, spinal cord stimulation systems have been used as a therapeutic modality for the treatment of chronic pain syndromes. Peripheral nerve stimulation has been used to treat chronic pain syndrome and incontinence, with a number of other applications under investigation. Functional electrical stimulation systems have been applied to restore some functionality to paralyzed extremities in spinal cord injury patients.
Stimulators have been developed to provide therapy for a variety of treatments. A stimulator can include a control module (with a pulse generator) and one or more stimulator electrodes. The one or more stimulator electrodes can be disposed along one or more leads, or along the control module, or both. The stimulator electrodes are in contact with or near the nerves, muscles, or other tissue to be stimulated. The pulse generator in the control module generates electrical pulses that are delivered by the electrodes to body tissue.

Non-limiting and non-exhaustive embodiments of the present invention are described with reference to the following drawings. In the drawings, like reference numerals refer to like parts throughout the various figures unless otherwise specified.
For a better understanding of the present invention, reference will be made to the following Detailed Description, which is to be read in association with the accompanying drawings, wherein:
The present disclosure is directed to the area of implantable electrical stimulation systems and methods of making and using the systems. The present disclosure is also directed to a connector assembly for an electrical stimulation system, as well the system and methods for making and using the connector.
Suitable implantable electrical stimulation systems include, but are not limited to, a least one lead with one or more electrodes disposed on a distal portion of the lead and one or more terminals disposed on one or more proximal portions of the lead. Leads include, for example, percutaneous leads, paddle leads, cuff leads, or any other arrangement of electrodes on a lead. Examples of electrical stimulation systems with leads are found in, for example, U.S. Pat. Nos. 6,181,969; 6,516,227; 6,609,029; 6,609,032; 6,741,892; 7,244,150; 7,450,997; 7,672,734;7,761,165; 7,783,359; 7,792,590; 7,809,446; 7,949,395; 7,974,706; 8,175,710; 8,224,450; 8,271,094; 8,295,944; 8,364,278; 8,391,985; and 8,688,235; and U.S. Patent Applications Publication Nos. 2007/0150036; 2009/0187222; 2009/0276021; 2010/0076535; 2010/0268298; 2011/0005069; 2011/0004267; 2011/0078900; 2011/0130817; 2011/0130818; 2011/0238129; 2011/0313500; 2012/0016378; 2012/0046710; 2012/0071949; 2012/0165911; 2012/0197375; 2012/0203316; 2012/0203320; 2012/0203321; 2012/0316615; 2013/0105071; and 2013/0197602, all of which are incorporated by reference. In the discussion below, a percutaneous lead will be exemplified, but it will be understood that the methods and systems described herein are also applicable to paddle leads and other leads.
A percutaneous lead for electrical stimulation (for example, deep brain, spinal cord, peripheral nerve, or cardiac-tissue stimulation) includes stimulation electrodes that can be ring electrodes, segmented electrodes that extend only partially around the circumference of the lead, or any other type of electrode, or any combination thereof. The segmented electrodes can be provided in sets of electrodes, with each set having electrodes circumferentially distributed about the lead at a particular longitudinal position. A set of segmented electrodes can include any suitable number of electrodes including, for example, two, three, four, or more electrodes. For illustrative purposes, the leads are described herein relative to use for deep brain stimulation, but it will be understood that any of the leads can be used for applications other than deep brain stimulation, including spinal cord stimulation, peripheral nerve stimulation, dorsal root ganglion stimulation, sacral nerve stimulation, or stimulation of other nerves, muscles, and tissues.
Turning to
The IPG 14 is physically connected, optionally, via one or more lead extensions 24, to the stimulation lead(s) 12. Each lead carries multiple electrodes 26 arranged in an array. The IPG 14 includes pulse generation circuitry that delivers electrical stimulation energy in the form of, for example, a pulsed electrical waveform (i.e., a temporal series of electrical pulses) to the electrode array 26 in accordance with a set of stimulation parameters. The implantable pulse generator 14 can be implanted into a patient's body, for example, below the patient's clavicle area or within the patient's buttocks or abdominal cavity. The implantable pulse generator 14 can have eight stimulation channels which may be independently programmable to control the magnitude of the current stimulus from each channel. In some embodiments, the implantable pulse generator 14 can have more or fewer than eight stimulation channels (e.g., 4-, 6-, 16-, 32-, or more stimulation channels). The implantable pulse generator 14 can have one, two, three, four, or more connector ports, for receiving the terminals of the leads 12 and/or lead extensions 24.
The ETS 20 may also be physically connected, optionally via the percutaneous lead extensions 28 and external cable 30, to the stimulation leads 12. The ETS 20, which may have similar pulse generation circuitry as the IPG 14, also delivers electrical stimulation energy in the form of, for example, a pulsed electrical waveform to the electrode array 26 in accordance with a set of stimulation parameters. One difference between the ETS 20 and the IPG 14 is that the ETS 20 is often a non-implantable device that is used on a trial basis after the neurostimulation leads 12 have been implanted and prior to implantation of the IPG 14, to test the responsiveness of the stimulation that is to be provided. Any functions described herein with respect to the IPG 14 can likewise be performed with respect to the ETS 20.
The RC 16 may be used to telemetrically communicate with or control the IPG 14 or ETS 20 via a uni- or bi-directional wireless communications link 32. Once the IPG 14 and neurostimulation leads 12 are implanted, the RC 16 may be used to telemetrically communicate with or control the IPG 14 via a uni- or bi-directional communications link 34. Such communication or control allows the IPG 14 to be turned on or off and to be programmed with different stimulation parameter sets. The IPG 14 may also be operated to modify the programmed stimulation parameters to actively control the characteristics of the electrical stimulation energy output by the IPG 14. The CP 18 allows a user, such as a clinician, the ability to program stimulation parameters for the IPG 14 and ETS 20 in the operating room and in follow-up sessions. Alternately, or additionally, stimulation parameters can be programed via wireless communications (e.g., Bluetooth) between the RC 16 (or external device such as a hand-held electronic device) and the IPG 14.
The CP 18 may perform this function by indirectly communicating with the IPG 14 or ETS 20, through the RC 16, via a wireless communications link 36. Alternatively, the CP 18 may directly communicate with the IPG 14 or ETS 20 via a wireless communications link (not shown). The stimulation parameters provided by the CP 18 are also used to program the RC 16, so that the stimulation parameters can be subsequently modified by operation of the RC 16 in a stand-alone mode (i.e., without the assistance of the CP 18).
For purposes of brevity, the details of the RC 16, CP 18, ETS 20, and external charger 22 will not be further described herein. Details of exemplary embodiments of these devices are disclosed in U.S. Pat. No. 6,895,280, which is expressly incorporated herein by reference. Other examples of electrical stimulation systems can be found at U.S. Pat. Nos. 6,181,969; 6,516,227; 6,609,029; 6,609,032; 6,741,892; 7,949,395; 7,244,150; 7,672,734; and 7,761,165; 7,974,706; 8,175,710; 8,224,450; and 8,364,278; and U.S. Patent Application Publication No. 2007/0150036, as well as the other references cited above, all of which are incorporated by reference.

Percutaneous leads are described herein for clarity of illustration. It will be understood that paddle leads and cuff leads can be used in lieu of, or in addition to, percutaneous leads. The leads described herein include 8 electrodes (+1 auxiliary electrode in some embodiments). It will be understood that the leads could include any suitable number of electrodes. The leads described herein exclusively include ring electrodes. It will be understood that the leads can include a distal-tip electrode, or one or more segmented electrodes in lieu of, or in addition to one or more ring electrodes. Additionally, the term “elongated member” used herein includes leads (e.g., percutaneous, paddle, cuff, or the like), as well as intermediary devices (e.g., lead extensions, adaptors, splitters, or the like).
Conductors can extend along the longitudinal length of the lead 212 within one or more lumens defined in the lead. In other instances, the conductors may extend along the lead 212 within the lead body itself. The lead 212 includes an auxiliary terminal 208 disposed along the proximal portion of the body 206 to facilitate coupling of the proximal portion of the lead to a connector. The connector may be disposed along a control module. Alternatively, the auxiliary terminal 208 can be used to facilitate coupling of the proximal portion of the lead to a connector of an intermediary device, such as a lead extension which, in turn, is coupled to a connector of a control module.
The lead-extension connector 390 contains a lead-extension connector stack 365 that defines a connector lumen 367 configured to receive the proximal portion of an elongated member (e.g., lead 212). The lead-extension connector stack 365 includes lead-extension connector contacts, such as lead-extension connector contact 369, arranged along the connector lumen 367 and configured to electrically couple with terminals of the elongated member (e.g., lead 212) when the proximal portion of the elongated member is received by the lead-extension connector 390. The connector contacts can be electrically isolated from one another by electrically-nonconductive spacers, such as spacer 371. The connector stack may also include an end stop 373 to promote alignment of the elongated-member terminals with the lead-extension connector contacts.
The lead-extension connector 390 further includes a retention assembly for facilitating retention of the proximal portion of the elongated member (e.g., lead 212) when the proximal portion of the elongated member is received by the lead-extension connector 390. In the illustrated embodiment, the retention assembly includes a lead-extension retention block 392. The lead-extension retention block 392 is positioned to align with the auxiliary terminal (208 in
Lead-extension conductors, such as lead-extension conductor 331, extend along a longitudinal length of the lead extension 312 and electrically couple the lead-extension connector contacts to the array of lead-extension terminals 327. The lead-extension conductors can extend along the longitudinal length of the lead-extension body 306 within one or more lumens defined in the lead extension. In other instances, the lead-extension conductors may extend along the lead extension 312 within the lead-extension body 306 itself. The lead extension 312 includes an auxiliary terminal 308 disposed along the proximal portion of the lead-extension body 306 to facilitate coupling of the proximal portion of the lead extension to a connector, such as a control-module connector, another lead-extension connector, or the like.
A connector assembly 590 is disposed in the header 553. The connector assembly 590 is configured to receive an elongated device (e.g., the lead 212, the lead extension 312, or other intermediary device). The connector assembly 590 defines a connector lumen 567 configured to receive the proximal portion of the elongated member. An array of connector contacts, such as connector contact 569, is arranged along the connector lumen 567 and configured to electrically couple with terminals of the elongated member when the proximal portion of the elongated member is received by the connector 590. The connector contacts can be electrically isolated from one another by electrically-nonconductive spacers, such as spacer 571. The connector stack may also include an end stop 573 to promote alignment of the elongated-member terminals with the connector contacts.
Wires or contacts, such as wire 582, are electrically coupled to the electrical subassembly 558 and extend within the sealed housing 554 to a feedthrough interface 586 disposed along an interface between the header 553 and the sealed housing 554. The connector contacts are electrically coupled to interconnect conductors, such as wire 580, that extend along the header 553 and electrically couple the connector contacts to the wires 582 (and possibly feedthrough pins) at the feedthrough interface 586. In some embodiments, the header 553 is positioned over the feedthrough interface 586.
The connector assembly 590, optionally, includes a retention assembly for facilitating retention of the proximal portion of the elongated member when the proximal portion of the elongated member is received by the control module 552. In the illustrated embodiment, the retention assembly includes a retention block 592. The retention block 592 is positioned to align with a retention sleeve (see e.g., 608 in
A connector assembly for an IPG (or other device) is often disposed within a header attached to a sealed housing containing an electronic subassembly (e.g., the IPG) with a feedthrough interconnect between the header and the sealed housing. Many conventional feedthrough interconnects and headers are complex and expensive due to the many processes and components that are used.
This disclosure presents arrangements and methods that, in at least some embodiments, can combine or eliminate some of the expensive components such as the contact housings and connector stack. In at least some embodiments, the arrangements and methods may reduce or eliminate some of the difficult assembly processes, such as a pin bending process allowing for a Z-axis assembly, or may be less prone to damage during assembly. In at least some embodiments, the arrangements and methods may reduce electrical impedance by eliminating the contact housing as an electrical path. In at least some embodiments, the arrangements and methods may facilitate self-alignment or simpler alignment of the contacts. In at least some embodiments, the arrangements and methods may have a lower profile than conventional connector assemblies. In at least some embodiments, the arrangements and methods may have lower resistance to insertion of the proximal end of the lead or lead extension.

In other embodiments, there may be one, three, four, or more rows. In the illustrated embodiments, there are eight contact receptacles in each row for a total of 16 contact receptacles. In other embodiments, there may be any number of contact receptacles per row including, for example, 2, 4, 6, 8, 10, 12, 16 or more contact receptacles in each row.
In at least some embodiments, the lower contact housing 770, 770′ includes a channel 777 formed between the contact receptacles 763 for receiving adhesive, as described in more detail below.

The spacers 771 are made of any suitable non-conductive material including, but not limited to, flexible or resilient plastics, such as silicone, polyurethane, or the like. In at least some embodiments, spacers 771 form a seal between the receptacles in the upper and lower contact housings 772, 770 and may impede or prevent flow of fluid out of the lumen 767 in the connector assembly 790.
In at least some embodiments, an optional retention block 792 (
After the upper and lower contact housings 772, 770 are assembled and the spacers 771 positioned, the connector assembly 790 is essentially complete. Optionally, a connector housing 791 (
Some of the components (for example, a power source 1212, an antenna 1218, a receiver 1202, and a processor 1204) of the electrical stimulation system 1200 can be positioned on one or more circuit boards or similar carriers within a sealed housing of an implantable pulse generator (see e.g., 14 in
As another alternative, power can be supplied by an external power source 1212 through inductive coupling via the optional antenna 1218 or a secondary antenna. In at least some embodiments, the antenna 1218 (or the secondary antenna) is implemented using the auxiliary electrically-conductive conductor. The external power source can be in a device that is mounted on the skin of the user or in a unit that is provided near the user on a permanent or periodic basis.
If the power source 1212 is a rechargeable battery, the battery may be recharged using the optional antenna 1218, if desired. Power can be provided to the battery for recharging by inductively coupling the battery through the antenna to a recharging unit 1216 external to the user. Examples of such arrangements can be found in the references identified above. The electronic subassembly 1258 and, optionally, the power source 1212 can be disposed within a control module (e.g., the IPG 14 or the ETS 20 of
In one embodiment, electrical stimulation signals are emitted by the electrodes (e.g., 26 in
Any processor can be used and can be as simple as an electronic device that, for example, produces pulses at a regular interval or the processor can be capable of receiving and interpreting instructions from an external programming unit 1208 that, for example, allows modification of pulse characteristics. In the illustrated embodiment, the processor 1204 is coupled to a receiver 1202 which, in turn, is coupled to the optional antenna 1218. This allows the processor 1204 to receive instructions from an external source to, for example, direct the pulse characteristics and the selection of electrodes, if desired.
In one embodiment, the antenna 1218 is capable of receiving signals (e.g., RF signals) from an external telemetry unit 1206 which is programmed by the programming unit 1208. The programming unit 1208 can be external to, or part of, the telemetry unit 1206. The telemetry unit 1206 can be a device that is worn on the skin of the user or can be carried by the user and can have a form similar to a pager, cellular phone, or remote control, if desired. As another alternative, the telemetry unit 1206 may not be worn or carried by the user but may only be available at a home station or at a clinician's office. The programming unit 1208 can be any unit that can provide information to the telemetry unit 1206 for transmission to the electrical stimulation system 1200. The programming unit 1208 can be part of the telemetry unit 1206 or can provide signals or information to the telemetry unit 1206 via a wireless or wired connection. One example of a suitable programming unit is a computer operated by the user or clinician to send signals to the telemetry unit 1206.
The signals sent to the processor 1204 via the antenna 1218 and the receiver 1302 can be used to modify or otherwise direct the operation of the electrical stimulation system 1200. For example, the signals may be used to modify the pulses of the electrical stimulation system 1200 such as modifying one or more of pulse duration, pulse frequency, pulse waveform, and pulse strength. The signals may also direct the electrical stimulation system 1200 to cease operation, to start operation, to start charging the battery, or to stop charging the battery. In other embodiments, the stimulation system does not include the antenna 1218 or receiver 1202 and the processor 1204 operates as programmed.
Optionally, the electrical stimulation system 1200 may include a transmitter (not shown) coupled to the processor 1204 and the antenna 1218 for transmitting signals back to the telemetry unit 1206 or another unit capable of receiving the signals. For example, the electrical stimulation system 1200 may transmit signals indicating whether the electrical stimulation system 1200 is operating properly or not or indicating when the battery needs to be charged or the level of charge remaining in the battery. The processor 1204 may also be capable of transmitting information about the pulse characteristics so that a user or clinician can determine or verify the characteristics.
The above specification and examples provide a description of the manufacture and use of the invention. Since many embodiments of the invention can be made without departing from the spirit and scope of the invention, the invention also resides in the claims hereinafter appended.
