Devices and methods for treating mitral valve regurgitation
First Claim
1. A medical device comprising:
- a) a tissue plicator adapted and configured to form a plication of tissue proximate a target region of a patient;
b) a retainer applicator operatively associated with the tissue plicator, the retainer applicator adapted and configured to apply a retainer to the plication to maintain the plication after the medical device is removed from the patient.

Abstract
A medical device, method and system of treating the lumenal system of a patient are provided. The medical device includes a tissue plicator adapted and configured to form a plication of tissue proximate a target region of a patient. The medical device further includes a retainer applicator operatively associated with the tissue plicator. The retainer applicator is adapted and configured to apply a retainer to the plication to maintain the plication after the medical device is removed from the patient. In accordance with a further aspect, the tissue plicator may plicate tissue by mechanically clamping the tissue and/or may plicate the tissue at least in part by applying suction thereto. The system can be used to plicate tissue proximate the mitral valve of a patient. The plication can be formed temporarily or permanently.

37. A method comprising:
-
a) providing a inner catheter having a distal portion for creating a plication in tissue;
b) introducing the inner catheter into a lumenal system of a patient, and advancing the distal portion to a target region to be plicated;
c) temporarily plicating tissue proximate the target region to form a first plication;
d) applying a first retainer to the first plication; and
e) removing the inner catheter from the patient. - View Dependent Claims (38, 39, 40, 41, 42, 43, 44, 45, 46, 47)
