Abstract
An implantable leadless cardiac pacing device including 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 tissue anchoring member extending from the distal end of the housing configured to secure the housing to cardiac tissue. The device further includes a tissue engagement verification feature configured to provide feedback upon engagement of the tissue anchoring member in cardiac tissue.

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;
- a tissue anchoring member extending from the distal end of the housing configured to secure the housing to cardiac tissue;
- and
- a tissue engagement verification feature configured to provide feedback upon engagement of the tissue anchoring member in cardiac tissue.
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;
- a tissue anchoring member extending from the distal end of the housing configured to secure the housing to cardiac tissue;
- and
- a radiopaque marker movable relative to the housing;
- and
- a radiopaque reference point stationary relative to the housing;
- wherein displacement of the radiopaque marker relative to the radiopaque reference point provides visual feedback of engagement of the tissue anchoring member in cardiac tissue.
A method of implanting a leadless cardiac pacing device, comprising:
- advancing the leadless cardiac pacing device into a chamber of a heart;
- engaging a tissue anchoring member of the leadless cardiac pacing device into cardiac tissue;
- fluoroscopically observing displacement of a radiopaque marker of the leadless cardiac pacing device relative to a radiopaque reference point to confirm engagement of the tissue anchoring member in cardiac tissue.
