Tissue to tissue anchoring device and method of using the same
First Claim
1. An apparatus for insertion into a body orifice for anchoring a first body tissue layer to a second body tissue layer comprising:
- a sheath having a bore therethrough, a proximal end, and a distal end for insertion through at least two body tissue layers and into a body orifice from a point exterior to the body orifice;
a hollow preshaped microthin polymeric device having a shaft and a ballooning retention element proximal to a distal end, the device being slidably engaged within the bore of the sheath such that the distal ends of each are proximate to one another and the retention element is in a first collapsed state and a second free end of the device protrudes from the proximal end of the sheath, the device adapted to be slid distally through the bore until at least the retention element is free of the sheath whereupon an inflation source may be applied to the device ballooning the retention element into a second expanded state.

Abstract
The invention describes a device and method for anchoring two or more body tissue layers to one another. The device in one form may be a hollow, collapsible, microthin polymeric shaft affixed to a noncollapsible tip at a distal end of die polymeric shaft. A preformed balloonable distention formed in a discrete region of the shaft proximal to die noncollapsible tip would be adapted to anchor against one of die body tissue layers within a body orifice. A rod attached at one end to the tip which extends along die shaft and terminates at a second end near a proximal end of the device would be used for transferring movement from the second end to die first end so as to effect a movement in the tip. The method pertains to the method of using such a device to secure one or more tissue layers together, ultimately to assist in the fusion of the layers.

9. A method for anchoring a first body tissue layer to a second body tissue layer comprising:
-
inserting a distal end of a sheath having a throughbore into a body through at least a first body tissue layer, a second body tissue layer, and into a body cavity, leaving a proximal end of the sheath protruding externally from the body; advancing a hollow preshaped microthin polymeric device having a shaft with a ballooning retention element integrated into a distal end of the shaft along the throughbore until the retention element protrudes from the distal end of the sheath; ballooning the retention member by inflating the member so that it expands from a first deflated condition to a second inflated condition; withdrawing the sheath from the body and freeing it from the polymeric shaft at a proximal end of the shaft; pulling the first and second body tissue layers one toward the other by applying a tensile force to the shaft so that the retention member contacts and draws one body tissue layer toward the other body tissue layer. - View Dependent Claims (10, 11)

12. A method for anchoring two or more body tissue layers to one another comprising:
-
perforating the first and second body tissue layers to create a stoma extending from a first region to a second region within a body orifice; advancing a hollow preshaped microthin polymeric device having a shaft with a ballooning retention element integrated into a distal end of the shaft into the body orifice by manipulating a rod attached at the distal end and extending to a proximal end until the ballooning retention element is situated; ballooning the retention member by inflating the member so that it expands from a first deflated condition to a second inflated condition; and pulling the first and second body tissue layers one toward the other by applying a tensile force to the shaft so that the retention member contacts and draws one body tissue layer toward the other body tissue layer. - View Dependent Claims (13, 14, 15)
