Method for anchoring a medical device between tissue
First Claim
1. A method for implanting a medical device in a patient'"'"'s body, the device including a housing having a proximal end, a distal end and a longitudinal axis, the method comprising:
- providing a plurality of ring members formed as complete loops;
connecting a first plurality of a first plurality of said ring members tangentially to the distal end of the housing at different, respective angles about the longitudinal axis;
connecting a second plurality of ring members tangentially to the proximal end of the housing at different, respective angles about the longitudinal axis;
collapsing the first and second pluralities of ring members about respective connections with the housing into a collapsed position, in which the ring members are substantially parallel to the longitudinal axis of the housing;
inserting the medical device into tissue in a patient'"'"'s body using a catheter, while the ring members are in the collapsed position;
deploying the medical device at least partially from the catheter, causing the first set of ring members to move around said connections to a deployed position in which the ring members are substantially perpendicular to the longitudinal axis of the housing, so as to engage one side of the tissue; and
deploying the medical device completely from the catheter, causing the second set of ring members to move around said connections to the deployed position so as to engage another side of the tissue and to anchor the housing against the tissue.

Abstract
A method for implanting a medical device between tissue comprises the steps of providing a catheter having a body and a distal end thereof wherein the catheter includes an implantable device comprising a housing having a proximal end and a distal end and a longitudinal axis. The implantable device further includes a first set of anchoring members operatively connected to the proximal end of the housing and a second set of anchoring members operatively connected to the distal end of the housing. Both sets of anchoring members are movable between a collapsed position and a deployed position. Each set of anchoring members includes ring members connected to a housing of the device. Further steps of the method include inserting the distal end of the catheter into tissue and disposing the medical device at least partially from the distal end of the catheter. The first set of anchoring members are moved from the collapsed position to the deployed position and one side of the tissue is engaged with the tissue engaging surfaces of each ring member of the first set of anchoring member. The medical device is further disposed completely from the distal end of the catheter wherein the second set of anchoring members are moved from the collapsed position to the deployed position and the other side of the tissue is engaged with the tissue engaging surfaces of each ring member of the second set of anchoring members.
