Abstract
A biostimulator includes a housing having a longitudinal axis and containing an electronics compartment. A pacing element is coupled to the housing. The pacing element includes a conductor extending along the longitudinal axis to a pacing tip. The biostimulator includes a sheath surrounding the conductor. The sheath includes one or more protrusions extending radially outward from an outer sheath surface.
Claims23
A biostimulator, comprising:
- a housing having a longitudinal axis and containing an electronics compartment;
- and
- a pacing element coupled to the housing, wherein the pacing element includes a conductor extending along the longitudinal axis to a pacing tip, and a sheath surrounding the conductor, and wherein the sheath includes one or more protrusions extending radially outward from an outer sheath surface.
A biostimulator, comprising:
- a housing having a longitudinal axis and containing an electronics compartment;
- a fixation element mount mounted on the housing;
- and
- a fixation element mounted on the fixation element mount, wherein the fixation element extends helically about the longitudinal axis and has an outer dimension, wherein the outer dimension increases in a distal direction over a proximal section of the fixation element, and wherein the outer dimension decreases in the distal direction over a distal section of the fixation element.
A biostimulator, comprising:
- a housing having a longitudinal axis and containing an electronics compartment;
- a fixation element mount mounted on the housing, wherein the fixation element mount includes a compliant ring extending circumferentially about the longitudinal axis;
- and
- a fixation element mounted on the fixation element mount.
A biostimulator, comprising:
- a housing having a longitudinal axis and containing an electronics compartment;
- a fixation element mount mounted on the housing, wherein the fixation element mount includes a plurality of flexible barbs extending in a distal direction;
- and
- a fixation element mounted on the fixation element mount.
A biostimulator, comprising:
- a housing having a longitudinal axis and containing an electronics compartment;
- a pacing element coupled to the housing, wherein the pacing element includes a conductor extending along the longitudinal axis to a pacing tip, and a sheath surrounding the conductor;
- a fixation element mount mounted on the housing;
- and
- a fixation element mounted on the fixation element mount;
- wherein one or more of the sheath or the fixation element have a rough surface.
