[0028] This disclosure relates to an implantable medical device with an electronic pump device configured to automatically transfer fluid between a fluid reservoir and an inflatable member. In some examples, the implantable medical device includes a penile prosthesis with one or more inflatable cylinders. In some examples, the implantable medical device includes a urinary control device with an inflatable cuff. The electronic pump device includes a housing with a fluidic manifold having one or more pumps and one or more valves to facilitate the transfer of fluid between the fluid reservoir and the inflatable member. The fluidic manifold includes a shelf that retains and is coupled to a circuit substrate with a plurality of circuit components (e.g., electronic components). The circuit substrate includes a hole. The electronic pump device includes a coupling member that couples the circuit substrate to the shelf, where the coupling member extends through the hole.

[0029] In some examples, the coupling member includes a post that is integral to and extends from the shelf. In some examples, the coupling member includes a clip coupled to the post, where the circuit substrate has a portion disposed between the clip and the shelf. In some examples, the coupling member includes an adhesive material disposed on the post. In some examples, the coupling member includes a ring member coupled to the post, where the circuit substrate has a portion disposed between the ring member and the shelf. In some examples, the coupling member includes a rivet. In some examples, the coupling member includes injection molding. In some examples, the coupling member includes a threaded fastener.

[0030] FIGS. 1A-1F illustrates an implantable medical device 100 according to an aspect. In some examples, the implantable medical device 100 is an artificial urinary sphincter device. In some examples, the implantable medical device 100 is anAtty Docket No. 0073-693W01 inflatable penile prosthesis. However, the implantable medical device 100 may include any type of medical device that transfers fluid between components of the implantable medical device 100.

[0031] The implantable medical device 100 includes a fluid reservoir 102, an inflatable member 104, and an electronic pump device 106 configured to transfer fluid between the fluid reservoir 102 and the inflatable member 104. In some examples, the inflatable member 104 is an inflatable cuff member configured to be implemented around a urethra of a patient. In some examples, the inflatable member 104 is a penile inflation member (e.g., one or more inflatable cylinders) that may be implanted into the corpus cav emosum of the user. The fluid reservoir 102 may be implanted in the abdomen or pelvic cavity of the user (e.g., the fluid reservoir 102 may be implanted in the lower portion of the user's abdominal cavity or the upper portion of the user’s pelvic cavity). In some examples, at least a portion of the electronic pump device 106 may be implemented in the patient’s body.

[0032] The inflatable member 104 may be capable of expanding upon the injection of fluid into a cavity of the inflatable member 104. If implanted around the urethra, the expansion of the inflatable member 104 causes the urethra to become restricted, thereby reducing the risk of incontinence in patients. For example, the electronic pump device 106 is configured to move fluid to pressure the inflatable cuff (e.g., the inflatable member 104), which constricts the urethra, thereby restricting the flow of urine. To urinate, the patient may operate the electronic pump device 106 to depressurize the inflatable cuff by transferring fluid from the inflatable cuff to the fluid reserv oir 102. If implanted into the corpus cavemosum, upon injection of the fluid into the inflatable member 104, the inflatable member 104 may increase its length and / or width, as well as increase its rigidity.

[0033] The fluid reservoir 102 may include a container having an internal chamber configured to hold or house fluid that is used to inflate the inflatable member 104. In some examples, the fluid reservoir 102 is pressurized. In some examples, the fluid reservoir 102 is a pressurized balloon. In some examples, the implantable medical device 100 includes a single pressurized balloon. In some examples, the implantable medical device 100 includes two or more pressurized balloons. The pressure in the inflatable member 104 may be generated by the fluid reservoir 102.Atty Docket No. 0073-693W01

[0034] The implantable medical device 100 may include a first tube member 103 and a second tube member 105. In some examples, the first tube member 103 and the second tube member 105 are referred to as conduit connectors. Each of the first tube member 103 and the second tube member 105 may define a lumen configured to transfer the fluid to and from the electronic pump device 106. The first tube member 103 may be coupled to the electronic pump device 106 and the fluid reservoir 102 such that fluid can be transferred between the electronic pump device 106 and the fluid reservoir 102 via the first tube member 103. For example, the first tube member 103 may define a first lumen configured to transfer fluid between the electronic pump device 106 and the fluid reservoir 102. The first tube member 103 may include a single or multiple tube members for transferring the fluid between the electronic pump device 106 and the fluid reserv oir 102. In some examples, the first tube member 103 may be referred to as first tube members, and two first tube members can be connected together using a connector.

[0035] The second tube member 105 may be coupled to the electronic pump device 106 and the inflatable member 104 such that fluid can be transferred between the electronic pump device 106 and the inflatable member 104 via the second tube member 105. For example, the second tube member 105 may define a second lumen configured to transfer fluid between the electronic pump device 106 and the inflatable member 104. The second tube member 105 may include a single or multiple tube members for transferring the fluid between the electronic pump device 106 and the inflatable member 104. In some examples, the second tube member 105 may be referred to as second tube members, and two second tube members can be connected together using a connector. In some examples, the first tube member 103 and the second tube member 105 may include a silicone rubber material. In some examples, the electronic pump device 106 may be directly connected to the fluid reservoir 102.

[0036] The electronic pump device 106 that can monitor control and regulate the pressure within an inflatable member 104. In some examples, the electronic pump device 106 is referred to as a can. The electronic pump device 106 may automatically transfer fluid between the fluid reservoir 102 and the inflatable member 104 without the user manually operating a pump (e.g., squeezing and releasing a pump bulb). The electronic pump device 106 may include an antenna configured to wirelessly transmit (and receive) wireless signals from an external device 101. The external device 101Atty Docket No. 0073-693W01 may be any type of component that can communicate with the electronic pump device 106. The external device 101 may be a computer, smartphone, tablet, pendant, key fob, etc. A user may use the external device 101 to control the implantable medical device 100. In some examples, the user may use the external device to inflate or deflate the inflatable member 104.

[0037] Referring to FIGS. 1A to IE, the electronic pump device 106 includes a housing 120. The housing 120 includes a fluidic manifold 108 that attaches fluid transfer and pressure regulating components and a circuit substrate 110 with electronic components 112.

The fluidic manifold 108 may include fluidic components 174 such as one or more pumps (e.g., electrically controlled pumps) and one or more valves. The fluidic manifold 108 may include one or more pressure sensors 186. In some examples, the pressure sensors 186 include a first pressure sensor connected to the fluid reservoir 102 to detect a pressure in the fluid reservoir 102, and a second pressure sensor connected to the inflatable member 104 to detect a pressure in the inflatable member 104. The fluidic manifold 108 includes a frame 140 with an inside edge 123. The frame 140 may define a peripheral wall 136 (see FIG. IF), which is a portion of the outer surface of the electronic pump device 106. The fluidic manifold 108 includes a shelf 114 that extends from the inside edge 123.

[0038] The shelf 114 may extend from the inside edge 123. The circuit substrate 110 contacts the shelf 114.

The electronic pump device 106 includes one or more coupling members 116 that couple the circuit substrate 110 to the shelf 114. AAtty Docket No. 0073-693W01 coupling member 116 may be a component that can extend into a hole 115. In some examples, the coupling member 116 includes one or more retaining features that hold the circuit substrate 110 on the shelf 114. In some examples, a coupling member 116 includes a post that is integral to and extends from the shelf 114. However, the coupling member 116 may be other types of fasteners as discussed herein. As shown in FIGS. 1A to 1C, the coupling members 116 may include a coupling member 116-1, a coupling member 116-2, and a coupling member 116-3. Each of the coupling member 116-1, the coupling member 116-2, and the coupling member 116-3 may be inserted into a respective hole 115 on the circuit substrate 110.

[0040] As shown in FIG. IB, the shelf 114 may include one or more shelf portions (e.g., also referred to as shoulder portions) that extend from the inside edge 123 of the frame 140 in the directions Al and A2. The shelf 114 may have a thickness that extends in the direction A3. In some examples, the shelf portions extend from the inside edge 123 in the direction A2 and / or the direction A3 at multiple different lengths. The shelf portions may include a comer portion 135, a comer portion 137, a comer portion 139, and a comer portion 141. The comer portion 135 may define, include, or contact a coupling member 116-1. The comer portion 137 may define, include, or contact a coupling member 116-2. The comer portion 139 may define, include, or contact a coupling member 1 16-3.

The shelf portions may include a connecting portion 133 that extends between the comer portion 137 and the comer portion 139.

[0041] FIG. IF illustrates an example of an exploded view of an electronic pump device 106 according to an aspect. The housing 120 includes a first sidewall 132, a second sidewall 134, a peripheral wall 136, and a frame 140. The first sidewall 132, second sidewall 134, and the peripheral wall 136 are hermetically sealed together to form an internal compartment 150 within the housing 120.

[0042] The frame 140 is disposed within the internal compartment 150 to form a first partition 152 and a second partition 154 in such a manner that the first partition 152 is hermetically sealed from the second partition 154. The frame 140 can be integrally formed with the peripheral wall 136. the first sidewall 132. and / or the second sidewall 134. In some examples, the frame 140 is welded to the peripheral wall 136 or welded to the first sidewall 132, and / or the second sidewall 134. The firstAtty Docket No. 0073-693W01 sidewall 132. the peripheral wall 136. and the frame 140 may form the first partition 152. The second sidewall 134, the peripheral wall 136, and the frame 140 may form the second partition 154, which is opposite the frame 140 from the first partition 152.

[0043] The electronic pump device 106 can include a header 126 attached to the housing 120 to form an internal region 158 between an inner surface of the header 126 and an outer surface of the housing 120 that includes power and communication interface structures such as a secondary coil 128 and the antenna 130 external to the hermetically sealed housing 120. The header 126 is configured from a dielectric or insulative material, such as a radome, to allow the transmission of power and communication signals between the antenna 130 and a handset programmer or charger, and between the secondary coil 128 and the charger. For example, the header 126 may include an over-molded polymer affixed to the housing 120 and including the secondary coil 128 and the antenna 130 within the internal region 158. The secondary coil 128 and antenna 130 are constructed from a biocompatible material. In some examples, the secondary coil 128 and antenna 130 can be formed as a coil from a stamped titanium core clad with gold or silver. In some examples, the secondary' coil 128 and antenna 130 can be formed from a gold wire.

[0044] The electronic pump device 106 includes an energy storage system, such as a battery (e.g., a rechargeable power source) (e.g., a rechargeable battery), and electronic components 112 within the first partition 152. The electronic components 112 can be disposed on a circuit substrate 110, such as a plurality of circuit boards, within the first partition 152. The battery’ 160 can assume various forms appropriate to provide power for generating desired electncal signals and to store power provided from the electronic components 112. For example, the battery 160 can incorporate lithium-ion (Li+) chemistry, e.g., a lithium-ion battery to operate the electronic components 112. In some examples, the electronic components 112 can be implemented by various components including resistors, capacitors, transistors, and integrated circuits disposed on the circuit substrate 110. The secondary coil 128 and antenna 130 are electrically coupled to the electronic components 112 within the first partition 152, such as via a hermetic feedthrough component.

[0045] The electronic components 112 can include a recharge system, a communication system, and a controller. The recharge system includes hardware configured to interface with the secondary coil 128 to receive power signals, and toAtty Docket No. 0073-693W01 provide the power signals in a form suitable to recharge the battery 160 and can include circuitry to reduce the likelihood of overcharging the battery 160. The communication system includes hardware configured to interface with the antenna 130 to receive electrical communication signals. For instance, the communication system can be configured to communicate via a wireless personal area network technology such as a short-range communication protocol (e.g., Bluetooth) (e.g., Bluetooth Low Energy ), which is compatible with several operating systems that can be applied in mobile devices configured as external devices 101 (e.g., handset programmers). The communication system can include an integrated circuit to implement an applied communication technology. In some examples, the communication system can be used to transmit communication signals to other devices, such as a charger or the handheld programmer (e.g., external device 101), and the communication system can be implemented to generate communication signals and provide the communication signals to the antenna 130 for transmission. In some examples, the communication system can be configured to receive and transmit radio frequency signals via the antenna 130. The controller can include a microcontroller to operate the recharge system and to receive and operate in response to communication signals or generate communication signals from the communication system.

[0046] The electronic pump device 106 also includes a fluidic circuit 170 within the second partition 154 and opposite the frame 140 from the battery' 160 and electronic components 112. In some examples, the frame 140 can include an opening 142 that includes a hermetic interface 144, such as a feedthrough hermetically affixed to the frame 140. The electronic components 112 are operably coupled to the fluidic circuit 170 across the frame 140 via the hermetic interface 144. For example, the controller of the electronic components 112, powered by the battery 160, can cause the operation of the fluidic circuit 170 such as to control and monitor the fluidic circuit 170.

[0047] The fluidic circuit 170 includes a fluidic manifold 108 and fluidic components 174 operably coupled to the fluidic manifold 108. In some examples, the fluidic manifold 108 is a structure integrated into the frame 140 such that the fluidic manifold 108 and the frame 140 together form the hermetic barrier between the first partition 152 and the second partition 154 of the internal compartment 150. ForAtty Docket No. 0073-693W01 instance, the battery 160, the circuit substrate 110, or electronic components 112 can be coupled to a first major surface of the fluidic manifold 108 in the first partition 152, and the fluidic components 174 are operably coupled to a second, and opposite major surface of the fluidic manifold 108 in the second partition 154.

[0048] The fluidic circuit 170 provides for the transfer of the fluid between the fluid reservoir 102 and the inflatable member 104. The fluidic manifold 108, which can be a hermetic manifold, segments and contains the fluid from the internal compartment 150 to reduce the chance of fluid exchange and directs the fluid from a first port 176 to a second port 178 via internal fluid passageways or channels.

[0049] The fluidic components 174 include a plurality of fluid pumps, such as pumps 180, 182, a valve 184 mounted into the fluidic manifold 108 in fluidic communication with a manifold passageway to transfer fluid from the first port 176 to the second port 178. The pumps and the valve(s) are in fluid communication with a single fluid passageway between ports 176, 178. The fluidic components 174 also includes one or more pressure sensors 186 operably coupled to the fluidic manifold 108 and in fluidic communication with the passageway to detect a pressure of the fluid within the fluidic manifold 108.

[0050] The fluidic components 174 are included in a planar configuration on the fluidic manifold 108 in which the pumps 180, 182, valve 184, and pressure sensor 186 are mounted into the fluidic manifold 108 on a plane for slim profile within the second partition 154. The fluidic manifold 108 can include chambers 188 formed into the second major surface in which the chambers are fluidically coupled to the single passageway within the fluidic manifold 108. The chambers are configured to receive the pumps 180, 182, and valve 184 and one or more pressure sensors 186. In some examples, the fluidic manifold 108 can receive a piezoelectric pump. The fluidic manifold 108 can receive a component cover 190 over the fluidic components 174, which can be hermetically sealed to the second major surface.

[0051] In some examples, the electronic pump device 106 may include kink resistant tubing 192 that can extend through the header 126 and attached to the ports 176, 178 via components such as a barb 194 and O-rings. The kink resistant tubing 192 can be attached to the tube members 103, 105 to fluidically couple the electronic pump device 106 to the fluid reservoir 102 and the inflatable member 104.Atty Docket No. 0073-693W01
