A leadless biostimulator has a housing including an electronics compartment, an electronics assembly mounted in the electronics compartment, a proximal electrode that disposed on and/or integrated into the housing, and an electrical feedthrough assembly. The electrical feedthrough assembly includes a distal electrode and a flange. The flange is mounted on the housing. The distal electrode is electrically isolated from the flange by an insulator and configured to be placed in contact with target tissue to which a pacing impulse is to be transmitted by the leadless biostimulator. A mount is mounted on the flange and thereby mounted on the electrical feedthrough assembly. A fixation element is mounted on the mount and configured to facilitate fixation of the leadless biostimulator to tissue of a patient.

Leadless biostimulator and electrical feedthrough assembly for leadless biostimulator

A leadless biostimulator including an attachment feature to facilitate precise manipulation during delivery or retrieval is described. The attachment feature can be monolithically formed from a rigid material, and includes a base, a button, and a stem interconnecting the base to the button. The stem is a single post having a transverse profile extending around a central axis. The transverse profile can be annular and can surround the central axis. The leadless biostimulator includes a battery assembly having a cell can that includes an end boss. A tether recess in the end boss is axially aligned with a face port in the button to receive tethers of a delivery or retrieval system through an inner lumen of the stem. The attachment feature can be mounted on and welded to the cell can at a thickened transition region around the end boss. Other embodiments are also described and claimed.

Disclosed herein is an implantable electronic device. The device includes a housing and a header connector assembly coupled to the housing. The header connector assembly includes a DF4/IS4 assembly and a header including a bore. The DF4/IS4 assembly is locked within the bore via a locking datum arrangement that exists between the DF4/IS4 assembly and the header.

An electrical feedthrough assembly, which is configured to be mounted on a housing of a leadless biostimulator, comprises an electrode body including a cup having an electrode wall extending distally from an electrode base around an electrode cavity, an electrode tip mounted on a distal end of the electrode body, and a filler in the electrode cavity between the electrode base and the electrode tip, wherein the filler includes a therapeutic agent. The electrode tip is configured to be placed in contact with target tissue to which a pacing impulse is to be transmitted by the leadless biostimulator. A pin extends proximally from the electrode base, wherein the pin is configured to be into contact with an electrical connector of an electronics assembly within the housing of the leadless biostimulator.

A biostimulator, such as a leadless cardiac pacemaker, including an electrical feedthrough assembly mounted on a housing, is described. An electronics compartment of the housing can contain an electronics assembly to generate a pacing impulse, and the electrical feedthrough assembly can include an electrode tip to deliver the pacing impulse to a target tissue. A monolithically formed electrode body can have a pin integrated with a cup. The pin can be electrically connected to the electronics assembly, and the cup can be electrically connected to the electrode tip. Accordingly, the biostimulator can transmit the pacing impulse through the monolithic pin and cup to the target tissue. The cup can hold a filler having a therapeutic agent for delivery to the target tissue and may include retention elements for maintaining the filler at a predetermined location within the cup.

A pulse generator comprises a header connector assembly coupled with a housing. The header connector assembly includes a connector assembly and a header enclosing the connector assembly. The connector assembly includes an electrically insulative segment, a first electrically conductive segment, and a second electrically conductive segment axially spaced apart from the first electrically conductive segment by the electrically insulative segment. Each electrically conductive segment includes a connector ring, a spring housing and a spring supported by the spring housing. The connector ring and spring housing are in electrical communication with each other. The electrically insulative segment includes an insulator ring that is positioned between the first and second electrically conductive segments. The insulator ring includes a first end and a second end axially opposite the first end. The first end includes a first recess that opens axially and receives therein a portion of the first electrically conductive segment.

The present disclosure provides leadless pacemaker systems and methods. A leadless pacemaker includes a battery subassembly, a feedthrough subassembly, and an electronics subassembly coupled between the battery subassembly and the feedthrough subassembly, the electronics subassembly including an electronics package, and a housing configured to provide a hermetic seal and comprising a first retaining feature and a second retaining feature configured to secure the electronics package within the housing.

Systems and methods for leadless pacemaker electronics assemblies

In accordance with one embodiment, a leadless implantable medical device (LIMD), compromises a hermetic housing that has a distal portion and proximal portion. An electrode is proximate to the distal portion. An electronics package is disposed in the housing, in which the electronics package is configured to generate and deliver stimulation signals to the electrode. A fixation mechanism is disposed on the distal portion of the housing. A torque mechanism is disposed on the proximal portion of the housing. The torque mechanism has a tool engagement element movably coupled to the housing. The tool engagement element has a rotational force applied thereto during implant. The torque mechanism includes a torque limiter that maintains a fixed relation between the tool engagement element and the housing when in an engaged state. The torque limiter changes from the engaged state to a disengaged state when the rotational force exceeds a predetermined torque limit.
