Technical Field
[0001] This disclosure generally relates to a feedthrough connector assembly, and more particularly to an implantable medical device including said feedthrough connector assembly. Background Technology
[0002] Implantable medical devices, such as implantable pacemakers, can deliver pacing pulses to a patient's heart and monitor the patient's cardiac condition. In some instances, an implantable pacemaker includes a pulse generator and one or more electrical leads. For example, the pulse generator can be implanted in a small pouch in the patient's chest. The electrical leads can be coupled to the pulse generator, which may include circuitry for generating pacing pulses and / or sensing cardiac electrical activity. The electrical leads can extend from the pulse generator to a target site (e.g., the atrium and / or ventricle), such that electrodes at the distal ends of the leads are positioned at the target site. The pulse generator can then provide electrical stimulation to the target site and / or monitor cardiac electrical activity at the target site via the electrodes.
[0003] Other implantable pacemakers are configured to be implanted entirely within the heart chambers. Such pacemakers may be referred to as intracardiac pacing devices or leadless pacing devices, and may include one or more electrodes on their outer casing to deliver therapeutic electrical signals and / or sense intrinsic depolarization of the heart. These pacemakers may be positioned inside or outside the heart, and in some instances, may be anchored to the heart wall via a fixation mechanism. Summary of the Invention

[0028] This disclosure generally relates to a feedthrough connector assembly and an implantable medical device including said assembly. The assembly may include a connector and a dielectric substrate including a patterned conductive layer, wherein the dielectric substrate insulates the patterned conductive layer from the connector. The assembly may also include a feedthrough pin electrically connected to a conductive portion of the patterned conductive layer. The feedthrough pin extends through the dielectric substrate and the connector and beyond the outer surface of the connector while maintaining isolation from the connector. The feedthrough connector assembly may form part of an electronic module. This electronic module may be electrically connected to a power source to provide the implantable medical device.
[0029] A typical connector assembly for an implantable medical device may include a feedthrough pin that is electrically connected to an electronic module housed within the device housing. The feedthrough pin may extend from inside the housing and beyond the connector connected to the housing. Because one or both of the housing or the connector may be electrically active, the feedthrough pin is typically insulated from both the connector and the housing. Openings in the connector and the housing through which the feedthrough pin extends must be sealed to prevent bodily fluids and contaminants from flowing into the interior of the housing, which could damage the electronic components therein.
[0030] One or more embodiments of this disclosure may provide a feedthrough connector assembly including feedthrough pins that can be connected to an electronic module disposed within a device housing, wherein the feedthrough pins are reliably electrically connected to the module while making efficient use of space within the housing. The feedthrough connector assembly may be compatible with various standard surface mount processes and reliably and dimensionally efficient in connecting to solderable components or subassemblies of integrated circuits or die stacks.
[0031] Figure 1 This is a schematic diagram of one embodiment of an implantable medical device 12 (IMD) disposed within the body of patient 2. IMD 12 may include any suitable medical device, such as a pacemaker, pressure sensor, cardiac monitor, other physiological sensors, etc. IMD 12 may include the arrangement of electronic modules and feedthrough connector assemblies, as further described herein. IMD 12 may be, for example, an implantable leadless pacemaker configured to be fully implanted in a chamber of heart 4 and to deliver electrical signals to the heart below sternum 3 via electrodes carried on the pacemaker's housing.
[0032] The IMD 12 is typically described as an intracardiac pacing device attached to a chamber of the heart 4. In one or more embodiments, the IMD 12 may be attached to the outer surface of the heart 4, such that the device is located outside the heart but can pace in the desired chamber. In one or more embodiments, the IMD 12 is attached to the outer surface of the heart 4, and one or more components of the device may contact the epicardium of the heart. Figure 1 The diagram schematically illustrates an IMD 12, which is attached to the ventricular wall of the heart 4 via one or more fixation elements (e.g., serrations, spirals, etc.) that penetrate the tissue. These fixation elements secure the IMD 12 to the cardiac tissue and maintain contact between the electrodes (e.g., cathodes or anodes) and the cardiac tissue. The IMD 12 can be implanted at or near the apex of the heart. In one or more embodiments, the pacing device can be implanted at other ventricular locations, such as on the free wall or septum, at the atrium, or anywhere on or within the heart 4.
[0033] Figure 2 yes Figure 1 A schematic side view of the IMD 12. In one or more embodiments, the IMD 12 is adapted to be implanted within the cardiac chamber of the heart 4 of a patient 2, for example, to monitor the electrical activity of the heart and / or to deliver electrical therapy to the heart. Figure 2 In the example shown, IMD 12 includes a housing 14, fixed teeth 16, and electrodes 18 and 20.
[0034] The housing 14 of the IMD 12 may include any suitable size and take any suitable one or more shapes. The housing 14 extends along the longitudinal axis 10 between a first end 6 and a second end 8. In one or more embodiments, the housing 14 may have a cylindrical (e.g., pill-shaped) shape factor. In one or more embodiments, the housing 14 comprises an elongated tubular housing. Furthermore, the housing 14 may include any suitable one or more materials as further described herein.
[0035] The IMD 12 may include a fixation mechanism suitable for securing the pacemaker 12 to tissue within the patient 2. For example, in Figure 2In the embodiment illustrated in the figure, the IMD 12 includes retaining teeth 16 extending from the housing 14, the retaining teeth 16 being adapted to engage with tissue to substantially secure the housing in position within the patient 2. In one or more embodiments, the retaining teeth 16 are adapted to anchor the housing 14 to cardiac tissue such that the pacemaker 12 moves with the cardiac tissue during cardiac contraction. The retaining teeth 16 may comprise any suitable material, such as shape memory materials (e.g., nitinol). Although the IMD 12 includes multiple retaining teeth 16 adapted to anchor the device to tissue, in one or more embodiments, other types of fixation mechanisms (e.g., but not limited to barbs), coils, etc., may be used to secure the device to tissue.
[0036] The housing 14, also referred to as an elongated housing, houses the electronic components of the IMD 12, such as sensing circuitry for sensing electrical activity via electrodes 18 and 20 and treatment generation circuitry for delivering electrical stimulation therapy via the electrodes. The electronic components may include any discrete and / or integrated electronic circuitry implementing analog and / or digital circuitry capable of producing the functionality attributed to the IMD 12 described herein. In one or more embodiments, the housing 14 may also house components for sensing other physiological parameters, such as acceleration, pressure, sound, and / or impedance. Although shown with two electrodes 18 and 20, the device 12 may include any suitable number of electrodes disposed in any suitable portion or section of the housing.
[0037] Additionally, housing 14 may also house a memory containing instructions that, when executed by processing circuitry housed within the housing, cause IMD 12 to perform various functions belonging to the present invention. In one or more embodiments, housing 14 may house communication circuitry enabling IMD 12 to communicate with other electronic devices, such as a medical device programmer. In one or more embodiments, housing 14 may house an antenna for wireless communication. Housing 14 may also house a power source, such as a battery. Housing 14 may be hermetically sealed or nearly hermetically sealed using any suitable technology to help prevent fluid ingress into the housing. For example, in one or more embodiments, one or more portions of housing 14 may be hermetically sealed together using one or more laser diffusion bonding techniques described in jointly owned U.S. Patent No. 10,124,559B2 entitled KINETICALLY LIMITED NANO-SCALE DIFFUSION BOND STRUCTURES AND METHODS.
[0038] The IMD 12 includes electrodes 18, 20 that can be connected to the housing using any suitable one or more technologies. In one or more embodiments, at least one of the electrodes 18, 20 may be mechanically connected to the housing 14. In one or more embodiments, at least one of the electrodes 18, 20 may be defined by a conductive exterior of the housing 14. For example, electrode 20 may be defined by a conductive portion of the housing 14 that exposes tissue.
[0039] Electrodes 18 and 20 are insulated from each other. Electrode 18 may be referred to as a tip electrode, and retaining teeth 16 may be adapted to anchor IMD 12 to tissue such that electrode 18 remains in contact with the tissue. In one or more embodiments, retaining teeth 16 may also be electrically connected to one or more electronic components such that the teeth are adapted to direct electrical signals to the patient's tissue and / or receive electrical signals from the tissue. In one or more embodiments, a portion of housing 14 may be covered with or formed of insulating material to isolate electrodes 18 and 20 from each other and / or to provide the desired size and shape for one or both electrodes.
[0040] Electrode 20 may be part of housing 14, such as second portion 24, which does not include this insulating material. Electrode 20 may be most or all of housing 14, but most of housing (except for electrode 20) may be covered with an insulating coating. In one or more embodiments, electrode 20 may be coated with a material to facilitate conduction. In one or more embodiments, electrode 20 may be part of a separate ring portion of housing 14, which is conductive. Electrodes 18, 20 that may include conductive portions of the first portion 22 of housing 14 may be electrically connected to at least some electronics of pacemaker 12 (e.g., sensing circuitry, electrical stimulation circuitry, or both). In one or more embodiments, housing 14 may include end cap 26 that may accommodate or surround a feedthrough connector assembly (e.g., Figure 3 The feedthrough connector assembly 42) is used to electrically connect the electrode 18 to electronic devices within the housing 14, while insulating the electrode (e.g., including electrode 20 or other conductive portions of the housing) from the housing 14.
[0041] In such Figure 2In the embodiment illustrated in the figure, housing 14 includes a first portion 22 and a second portion 24. The first portion 22 may be disposed adjacent to a first end 6 of housing 14, while the second portion 24 may be disposed adjacent to a second end 8 of housing 14. As used herein, the term "adjacent to the first end" means that an element or component is disposed closer to the first end 6 of housing 14 than to the second end 8 of housing 14. Similarly, the term "adjacent to the second end" means that an element or component is disposed closer to the second end 8 of housing 14 than to the first end 6 of housing 14. In one or more embodiments, the second portion 24 may define at least a portion of a power supply compartment (e.g., a battery) housing the power source of IMD 12. In one or more embodiments, the second portion 24 may include conductive portions of housing 14 forming electrodes 20.
[0042] The second portion 24 of the housing may include a vent 35 disposed in any suitable location. The vent 35 may allow backfill gas exchange of the encapsulation device 12 prior to the first portion 22 being connected to the second portion. Once gas exchange is complete, the vent 35 may be sealed by welding, as further described in U.S. Patent Application No. 17 / 118,283, entitled HERMETIC ASSEMBLY AND DEVICEINCLUDING SAME, by Ruben et al.
[0043] The first portion 22 of housing 14 can be attached to the second portion 24 of housing using any suitable technology or one or more. In one or more embodiments, the first portion 22 of housing 14 can be attached to the second portion 24 of housing using laser bonding. For example, electromagnetic radiation (e.g., light) can be directed through the outer surface of the first portion 22 and focused at the interface between the first and second portions 24 to form a laser bond.
[0044] A bond can be formed between the first portion 22 and the second portion 24 of the housing 14 using any suitable electromagnetic radiation. In one or more embodiments, the electromagnetic radiation may include a laser, which may include any suitable wavelength or wavelength range. In one or more embodiments, the laser may include light having a wavelength of at least 200 nm. In one or more embodiments, the laser may include a wavelength not greater than 10,000 nm. For example, the laser may include UV light, visible light, IR light, and combinations thereof. In one or more embodiments, a UV laser may be used to provide light having a wavelength of about 350 nm and a pulse width of 30 ns. In one or more embodiments, the materials of the first portion 22 and the second portion 24 of the housing 14, as well as the power level and wavelength of the light used, may be selected such that the light does not directly damage, ablate, distort, or cut the housing, and that the first and second portions of the housing maintain their integral properties.
[0045] Generally, light can be provided by any suitable laser or laser system. For example, a laser can generate light with a relatively narrow set of wavelengths (e.g., a single wavelength). The light emitted by the laser can form a collimated beam, which may not be focused at a specific point. The light emitted by the laser can be focused at the interface between the first portion 22 and the second portion 22 of the housing 14 to generate laser bonding.
[0046] Although lasers can provide light with a narrow wavelength range, in one or more embodiments, a laser can represent one or more devices that emit light with a wider wavelength range than a single typical laser. A wide variety of devices can be used to emit light with narrow or wide wavelength ranges. In one or more embodiments, the laser can include one or more laser devices, including diode and fiber lasers. Laser sources can also include, for example, TI sapphire, argon ion, Nd:YAG, XeF, HeNe, dye, GaAs / AlGaAs, CO2, alexandrite, InGaAs, InGaAsP, Nd:glass, Yb:YAG, or Yb fiber lasers. Laser devices can also include one of continuous wave, modulated, or pulsed modes. Therefore, a wide variety of laser devices can be used in the bonding process. In one or more embodiments, the laser power level can be set to approximately 1W, distributed over a focused beam diameter of approximately 10 μm with a high-top-cap or Gaussian spatial energy profile.
[0047] exist Figure 2 In one embodiment, the IMD 12 may further include a flange 28 connected at the second end 8 of the housing defining an opening to the second portion 24 of the housing 14. The flange 28 allows a medical device to be attached to the IMD 12, for example, for delivery and / or removal of a device. For example, extending through the insertion into the heart 4 ( Figure 1 The tether of the catheter can be attached to the flange 28 and / or through the opening to insert or remove the IMD 12.
[0048] Figure 3 This is a schematic block diagram of one embodiment of IMD 12, including a power source 30 (e.g., a battery), an electronic module 32, and an electrical contact assembly 34. Although... Figure 3 The IMD is described as IMD 12, but Figure 3 The structure shown can also be used for other implantable or external medical devices, such as cardioverter defibrillators, physiological monitors or neurostimulators, or any other electronic devices.
[0049] The housing 14 includes a first portion 22, a second portion 24, and a sidewall 36 disposed within the housing between the battery 30 and the electrical contact assembly 34. The sidewall 36 may be disposed within the first portion 22 and the second housing portion 24 or at the boundary between the first housing portion and the second housing portion. In one or more embodiments, the first housing portion 22 and the second housing portion 24 are shared with a ground terminal of the battery 30. In one or more embodiments, one or both of the first housing portion 22 and the second housing portion 24 are non-conductive. For example, the first housing portion 22 may be formed of a non-conductive material such as sapphire, which can more easily transmit electromagnetic signals into and out of the housing 14 compared to metals or other conductive materials.
[0050] like Figure 3 As illustrated in the embodiment shown in the figure, a sidewall 36 extends across the housing 14 between the battery 30 on one side and the electrical contact assembly 34 on the other side. The sidewall 36 may include at least one feedthrough (not shown) to allow electrical connection between the battery 30 and the electronic module 32. As discussed herein, the feedthrough assembly 42 may also include at least one feedthrough to allow electrical connection between the electrode 18 and the electronic layer 40. The electronic module 32 is disposed between the electrode 18 and the electrical contact assembly 34. In one or more embodiments, the electrical contact assembly 34 may be secured to the sidewall 36 to provide mechanical support for the electronic module 32. The electrical contact assembly 34 provides electrical connection between the battery 30 and the electronic module 32. For example, the electronic module 32 may include one or more electrical contacts adapted to electrically connect the module to the electrical contact assembly 34.
[0051] IMD 12 may also include a battery connector 38 disposed between the battery 30 and the electrical contact assembly 34. A sidewall 36 may form part or all of the battery connector 38. The battery connector 38, sidewall 36, and electrical contact assembly 34 may be electrically connected to the electronic module 32 using any suitable technology or one or more of these methods. In one or more embodiments, the battery connector 38, sidewall 36, and / or electrical contact assembly 34 may include feedthroughs and / or openings for establishing an electrical connection between the battery 30 and the electronic module 32.
[0052] Electrical contact assembly 34 may include any suitable component for electrically connecting electronic module 32 and battery 30, such as one or more embodiments of the electrical contact assembly described in co-owned U.S. Patent Application Serial No. 17 / 071,463 entitled ELECTRONICS ASSEMBLY FOR IMPLANTABLE MEDICAL DEVICE. In one or more embodiments, electrical contact assembly 34 may include spring contacts for holding electronic module 32 in place and for providing an electrical connection between electronic module and battery 30.
[0053] The IMD 12 can be manufactured using a single tube for the first housing portion 22 or as two tube portions for such a housing portion. Using a single tube for the housing portion 22 reduces the cost and complexity of the pacemaker 12's housing compared to two portions (e.g., two half-tubes). The single tube opens up new housing options and can be manufactured from alternative materials. For example, a single sapphire tube for the first housing portion 22 could allow for wireless charging of the battery 30, even when the IMD 12 is implanted in a patient.
[0054] In one or more embodiments, at least one of the first portion 22 and the second portion 24 of the housing 14 may comprise a substantially transparent material. As used herein, the phrase “substantially transparent” means that, assuming no reflected light at the air-substrate boundary, the substrate transmits more than 50% of the electromagnetic radiation incident on the substrate for a selected wavelength or wavelength range. In one or more embodiments, at least one of the first portion 22 and the second portion 24 may substantially transmit electromagnetic radiation with a wavelength of at least 200 nm. In one or more embodiments, at least one of the first portion 22 and the second portion 24 may substantially transmit electromagnetic radiation with a wavelength greater than 10,000 nm. In one or more embodiments, at least one of the first portion 22 and the second portion 24 may substantially transmit electromagnetic radiation in the wavelength range of 200 nm to 10,000 nm. In one or more embodiments, at least one of the first portion 22 and the second portion 24 may substantially transmit at least one of UV light, visible light, or IR light. The substantially transparent material may comprise at least one of glass, quartz, silicon dioxide, sapphire, silicon carbide, diamond, or gallium nitride.
[0055] In one or more embodiments, the first housing portion 22 may include a substantially transparent material, allowing one or more sensors, transmitters, or detectors to be disposed within and emitting or receiving electromagnetic radiation through this portion. For example, Figure 4 yes Figures 1 to 3 The perspective view of IMD 12, with the first transparent portion 22 partially removed for clarity. (See image.) Figure 4 As shown, electronic module 32 is disposed within the first part 22.
[0056] Electronic module 32 may include any suitable element or component. For example, such as Figure 3 As shown, the electronic module 32 includes one or more layers of electronic layers 40 and feedthrough connector assemblies 42 electrically connected to one or more layers of electronic layers 40. The electronic module 32 may also include one or more coils 44 electrically connected to the electronic layers 40.
[0057] Figures 5 to 7 yes Figures 1 to 4 An exploded view of the electronic module 32 of the pacemaker 12. Module 32 includes an electronic layer 40 and a feedthrough connector assembly 42 electrically connected to the electronic layer.
[0058] Electronic layer 40 includes a first electronic layer 48, a second electronic layer 50, and a third electronic layer 52. Although illustrated as including three electronic layers, electronic layer 40 may include any suitable number of layers, such as one, two, three, four, five, or more layers. Each layer in electronic layer 40 may include a substrate. For example, the first electronic layer 48 includes a substrate 54 having a first main surface 56 and a second main surface 58.
[0059] The electronic layer 40 can be positioned relative to the feedthrough connector assembly 42 and the battery 30 in any suitable relationship. In one or more embodiments, the electronic layers 40 can be positioned such that they are substantially orthogonal to the longitudinal axis 10 of the IMD 12. Figure 5 The housing 14 of the device extends along a longitudinal axis. For example, the first main surface 56 of the substrate 54 of the first electronic layer 48 is substantially orthogonal to the longitudinal axis 10 of the housing 14. As used herein, the term “substantially orthogonal” means that the longitudinal axis 10 forms an angle of no more than 10 degrees with one or more substrates in the electronic layers 40.
[0060] The electronic layers 40 can be electrically connected together using any suitable one or more techniques. In one or more embodiments, one or more layers of the electronic layers 40 may include one or more conductive vias configured to pass through the respective substrates of one or more layers of the electronic layers. Furthermore, one or more conductive pads 60 may be disposed on one or more layers of the conductive layers 40 to provide electrical connections between the feedthrough assembly 42 and the conductive layers, between layers of the conductive layers, and between the conductive layers and the electrical contact assembly 34. For example, the conductive pads 62 may be disposed between the feedthrough assembly 42 and the first electronic layer 48 (e.g., between their conductive surfaces) to provide an electrical connection between the feedthrough assembly and the first electronic layer. In one or more embodiments, this connection may be between the housing 14 and the first electronic layer 48, or between one or more of the pins 84 of the assembly and the first electronic layer. The conductive pads 60 may include any suitable conductive contacts, such as solder bumps, solder balls, conductive epoxy, brazing alloys, etc.
[0061] One or more layers of electronic layers 40 may include electronic components disposed on their respective substrates. For example, the first electronic layer 48 includes electronic components 64 disposed on a first main surface 56 of substrate 54. Electronic components 64 may be disposed on at least one of the first main surface 56 or the second main surface 58 of substrate 54. Any suitable number of electronic components may be disposed on one or both main surfaces 56, 58 of substrate 54. Furthermore, electronic components 64 may be electrically connected to one or more additional electronic components disposed on substrate 54 or on the second electronic layer 50 or the third electronic layer 52 using any suitable one or more techniques. In one or more embodiments, electronic components 64 may be disposed on a patterned conductive layer (not shown) disposed on substrate 54 using any suitable one or more techniques. One or more conductive vias may be disposed between the first main surface 56 and the second main surface 58 of substrate 54 to provide one or more conductive paths between the patterned conductive layer and other elements or components disposed on the side of substrate 54 opposite to the electronic components. Furthermore, one or more conductive pads 60 may be directly connected to electronic components 64 to electrically connect the components to one or more additional components or devices.
[0062] Coil 44 is electrically connected to one or more layers of electronic layer 40. This coil 44 may include any suitable number of coils disposed on or within housing 46, and one or more electronic components also disposed within housing 46. Coil 44 can be used to inductively couple device 12 to an external inductive charging system for charging the device when implanted in patient 4, or for telemetry or other types of communication with a transceiver outside the patient. Coil 44 can be electrically connected to electronic layer 40 using any suitable one or more technologies.
