Methods and devices for cardiac valve repair or replacement
First Claim
1. A delivery system for percutaneously delivering and attaching at least one clip and attached suture in a desired position within a patient, the delivery system comprising:
- a longitudinal support tube having a distal end;
a deformable centering loop extending from the distal end of the support tube, the centering loop having a length, an exterior surface, a first portion and a second portion, wherein the first portion and the second portion meet at a distal end of the centering loop;
at least one stop positioned on the centering loop and spaced from the distal end of the support tube;
at least one clip delivery system slidably attached to the centering loop, wherein the at least one clip delivery system is slidable over the exterior surface of the centering loop until it reaches the at least one stop positioned thereon; and
a sheath that is longitudinally slidable relative to the support tube, the centering loop, and the at least one clip delivery system.

12. A delivery system, for percutaneously delivering and attaching at least one clip and attached suture in a desired position within a patient, the delivery system comprising:
-
a longitudinal support tube having a distal end; a deformable centering loop extending from the distal end of the support tube, the centering loop having a length, an exterior surface, a first portion and a second portion, wherein the first portion and the second portion meet at a distal end of the centering loop; at least one stop positioned on the centering loop and spaced from the distal end of the support tube; at least one clip delivery system slidably attached to the centering loop, wherein each clip delivery system comprises a clip delivery tube comprising a distal end and a linking member attached to the clip delivery tube adjacent to its distal end, wherein the linking member is slidable along the length of the exterior surface of the centering loop; and a sheath that is longitudinally slidable relative to the support tube, the centering loop, and the at least one clip delivery system. - View Dependent Claims (13)
