An implantable medical device system is configured to generate signals and deliver the signals to a heart of a patient. The implantable medical device system includes electronic circuitry configured to deliver cardiac pacing, couplings for an implantable medical lead receptacle, at least some of the couplings electrically connected with the electronic circuitry, a polymeric enclosure having the electronic circuitry contained therein, the polymeric enclosure formed of polymeric material filled around the electronic circuitry and couplings and forming the implantable medical lead receptacle. The implantable medical device may include a first cavity filled with a first material and a second cavity filled with a second material, and the first material is different than the second material.

Polymeric enclosure for implantable medical device

Various embodiments of a feedthrough header assembly and a device including such assembly are disclosed. The assembly includes a header having an inner surface and an outer surface; a dielectric substrate having a first major surface and a second major surface, where the second major surface of the dielectric substrate is disposed adjacent to the inner surface of the header; and a patterned conductive layer disposed on the first major surface of the dielectric substrate, where the patterned conductive layer includes a first conductive portion and a second conductive portion electrically isolated from the first conductive portion. The assembly further includes a feedthrough pin electrically connected to the second conductive portion of the patterned conductive layer and disposed within a via that extends through the dielectric substrate and the header. The feedthrough pin extends beyond the outer surface of the header.

Feedthrough assembly and device including same

An implantable medical device (IMD) includes a body, a fixation component, and an interface assembly. The body extends from a proximal portion to a distal portion along a longitudinal axis. The fixation component includes a penetrator tine. The penetrator tine includes an incisive distal end configured to penetrate a tissue to fix the IMD to the tissue. The electrode interface assembly includes a proximal section and a distal section. The proximal section is attached to and extends distally from the distal portion of the body along the longitudinal axis. The distal section extends from the proximal section of the electrode interface assembly and defines a non-incisive distal end. The distal end of the electrode interface assembly is configured to contact the tissue to control a depth of tissue penetration of the penetrator tine.

Fixation component for multi-electrode implantable medical device

In some examples, an implantable medical device includes a battery, an electronics module electrically connected to the battery, and an elongated housing comprising a side wall positioned between the battery and an end cap, wherein the electronics module is positioned within the elongated housing between the battery and the end cap. The implantable medical device also includes an electrical contact assembly comprising a first spring contact and a second spring contact. The electrical contact assembly of the implantable medical device is positioned within the elongated housing between the electronics module and the battery or the end cap.

Electronics assembly for implantable medical device

An example fixation component for an implantable medical device (IMD) includes a base and tines extending from the base and being spaced apart from one another. The tines include a penetrator tine and a protector tine. The penetrator tine includes a curved section defining a deformable preset curvature that extends laterally from a proximal section that is fixed to the base, traversing a longitudinal axis of the fixation component, to a distal section that terminates in an incisive distal end that is configured to penetrate a tissue to form a puncture. The protector tine includes a curved section defining a deformable preset curvature that extends from a proximal section that is fixed to the base, outward from the longitudinal axis, to a distal section that terminates in a non-incisive distal end that is configured to pass through the puncture.
