Abstract

An apparatus includes a hemostatic clip assembly including at least one hemostatic clip, a first one of the at least one hemostatic clips having a tissue clamp movable between a tissue receiving configuration and a tissue clamping configuration and a deployment mechanism deploying a distal most one of the clips onto target tissue and a cautery apparatus applying energy to the distal most one of the clips to cauterize the target tissue.

Claims

1. An apparatus, comprising:

a hemostatic clip assembly comprising a plurality of hemostatic clips, a first one of the hemostatic clips having a tissue clamp movable between a tissue receiving configuration and a tissue clamping configuration, each of the hemostatic clips including an insulating layer along an inner surface for conductive isolation from other hemostatic clips;

a magazine receiving the hemostatic clips in a chain therein, with each clip coupling to an adjacent clip;

a deployment mechanism deploying a distal most one of the clips onto target tissue, the distal most one of the clips remaining on the chain until deployment; and

a cautery apparatus heating only the distal most one of the clips to cauterize the target tissue.

2. The apparatus according to claim 1, wherein the cautery apparatus comprises an electric element transmitting electric energy to the distal most clip.

3. The apparatus according to claim 1, wherein the deployment mechanism is coupled to a user operated actuator commanding deployment of the distal most clip.

4. The apparatus according to claim 1, wherein the cautery element operates concurrently with the deployment mechanism to provide combination therapy.

5. The apparatus according to claim 1, wherein the electric element extends through the magazine to couple to the distal most clip.

6. A device, comprising:

a mechanical compression element deploying a hemostatic clip onto target tissue, the hemostatic clip including an insulating layer along an inner surface for conductive isolation from a further proximally disposed hemostatic clip;

a magazine containing therein the hemostatic clip and a plurality of further hemostatic clips arranged in a chain, the hemostatic clip coupling to an adjacent further hemostatic clip and remaining on the chain until deployment; and

a heating mechanism heating only the hemostatic clip to cauterize the target tissue.

7. The device according to claim 6, wherein the heating mechanism includes a conductor supplying electric energy to the hemostatic clip.

8. The device according to claim 6, wherein the heating mechanism includes a conductor extending through a wall of the magazine to a location adjacent to a distal most one of the clips.

9. The device according to claim 6, further comprising a shaft housing the mechanical compression element, the heating element, and the heated hemostatic clip, the shaft being dimensioned to fit through a working channel of an endoscope.
