RETRIEVABLE CARDIAC DEVICES

摘要

Removable cardiac implants, applicators for inserting, repositioning and/or removing them, and methods of using them are described. In particular, removable or repositionable ventricular partitioning devices are described. Systems including removable implants and applicators for inserting and/or removing them are also described.

1. A method for removing or repositioning an implant in a heart chamber, the implant including a plurality of self-expanding struts and a strand extending transversely across the struts, the method comprising:
providing an applicator comprising an elongate body having a proximal end, a distal end, and a strand capture element extendable from the distal end; inserting the distal end of the applicator into the heart chamber; extending the strand capture element from the distal end of the applicator; engaging the strand capture element with the strand; tensioning the strand with the strand capture element to collapse the self-expanding struts of the implant; and withdrawing at least a portion of the collapsed self-expanding struts of the implant into the distal end of the applicator.
