Abstract
An implantable leadless cardiac pacing device and associated retrieval features. The implantable device includes a docking member extending from the proximal end of the housing of the implantable device including a covering surrounding at least a portion of the docking member configured to facilitate retrieval of the implantable leadless cardiac pacing device.
Claims20
An implantable leadless cardiac pacing device comprising:
- a housing having a proximal end and a distal end;
- an electrode positioned proximate the distal end of the housing configured to be positioned adjacent cardiac tissue;
- and
- a docking member extending from the proximal end of the housing along a longitudinal axis of the housing, the docking member configured to facilitate retrieval of the implantable leadless cardiac pacing device;
- the docking member including a head portion and a neck portion extending between the housing and the head portion;
- the head portion having a radial dimension from the longitudinal axis and the neck portion having a radial dimension from the longitudinal axis less than the radial dimension of the head portion;
- and
- a covering surrounding at least a portion of the neck portion of the docking member.
An implantable leadless cardiac pacing device comprising:
- a housing having a proximal end and a distal end;
- an electrode positioned proximate the distal end of the housing configured to be positioned adjacent cardiac tissue;
- and
- a docking member extending from the proximal end of the housing along a longitudinal axis of the housing, the docking member configured to facilitate retrieval of the implantable leadless cardiac pacing device;
- the docking member including a head portion and a neck portion extending between the housing and the head portion;
- the head portion having a radial dimension from the longitudinal axis and the neck portion having a radial dimension from the longitudinal axis less than the radial dimension of the head portion;
- and
- a collapsible covering located between the head portion of the docking member and the proximal end of the housing, the collapsible covering having a peripheral surface collapsible toward the neck portion when engaged with a retrieval device.
A method of retrieving an implantable cardiac pacing device, the implantable cardiac pacing device having a housing having a longitudinal axis, an electrode positioned proximate a distal end of the housing, and a docking member extending from a proximal end of the housing opposite the distal end, the docking member including a head portion, a neck portion extending between the housing and the head portion, and a covering surrounding at least a portion of the neck portion, the method comprising:
- advancing a snare toward the docking member;
- encircling the docking member with a loop of the snare;
- and
- cinching the loop around the neck portion of the docking member such that the covering collapses toward the longitudinal axis as the loop presses against the covering.
