Clamp applicator
First Claim
Patent Images
1. A clamp applicator for applying a resilient clamp having a normally closed position to body tissue, the clamp applicator comprising:
- a) a housing;
b) a clamp support member positioned distally of the housing and configured to support a resilient clamp;
c) an actuator positioned around the clamp support member and being movably mounted in relation to the clamp support member, a biasing member operably associated with the actuator, wherein the actuator is configured to urge the resilient clamp from the normally closed position to an open position; and
d) a locking device operably associated with the actuator, the locking device being positioned to retain the actuator and clamp support member at relative positions to maintain a resilient clamp in the open position.

Abstract
A clamp applicator is disclosed having a housing, a clamp support member extending distally from the housing, an actuator assembly and a locking device. The actuator assembly is movable with respect to the clamp support member into engagement with a clamp supported at the distal end of the clamp support member to bias the clamp to an open position. A locking device is provided to retain the actuator assembly in a position to maintain the clamp in the open position.

8. A clamp applicator for applying a resilient clamp having a normally closed position to body tissue, the clamp applicator comprising:
-
a) a housing; b) a clamp support positioned distally of the housing and configured to support a resilient clamp; c) an actuator movably mounted in relation to the clamp support member, a biasing member operably associated with the actuator, the actuator being configured to urge the resilient clamp from the normally closed position to an open position; and d) a locking device operably associated with the actuator, the locking device being positioned to retain the actuator and clamp support member at relative positions to maintain a resilient clamp in the open position wherein the clamp support member is fixed with rest to the housing, and the actuator is movable with respect to the housing and the clamp support member from a first position in which the resilient clamp is in the normally closed position to a second position in which a resilient clamp is biased to the open position, and wherein the locking device includes a camming plate and a flexible locking member, the flexible locking member being movable into operative engagement with the camming plate to retain the actuator in the second position. - View Dependent Claims (9, 10, 11, 12, 13)

14. A clamp applicator for applying a resilient clamp having a normally closed position to body tissue, the clamp applicator comprising:
-
a) a housing; b) a clamp support member extending distally from the housing and having a longitudinal axis, the clamp support member configured to support a resilient clamp; c) an actuator movable relative to the clamp support member to bias the resilient clamp from the normally closed position to an open position; and d) a locking device operably associated with the actuator, the locking device being movable to a locked position in which a resilient clamp is maintained in the open position; wherein the actuator is movable in a first direction a first distance to move the locking device to the locked position and the actuator is movable in the first direction a second distance substantially shorter than the first distance to release the actuator and permit a resilient clamp to return to the normally closed position. - View Dependent Claims (15, 16, 17, 18)
