CA 2661763

The invention describes a device (10) and method for anchoring two or more body tissue layers (22, 24) to one another. The device in one form may be a hollow, collapsible, microthin polymeric shaft (16) affixed to a noncollapsible tip (20) at a distal end (12) of the polymeric shaft. A preformed balloonable distention (18) formed in a discrete region of the shaft proximal to the noncollapsible tip would be adapted to anchor against one of the body tissue layers within a body orifice (26). A rod (50) attached at one end to the tip which extends along the 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 the f irst 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.

L'invention concerne un dispositif et un procédé d'ancrage de deux couches de tissu corporel ou plus entre elles. Le dispositif dans une forme donnée peut être un arbre polymère microfin, creux, pliant fixé à une pointe non pliante au niveau d'une extrémité distale de l'arbre polymère. Une détente gonflable préformée constituée dans une région discrète de l'arbre près de la pointe non pliante serait conçue pour s'ancrer contre l'une des couches de tissu corporel dans un orifice corporel. Une tige fixée en une extrémité à la pointe qui s'étend le long de l'arbre et se termine en une seconde extrémité près d'une extrémité proximale du dispositif servirait à transférer le mouvement de la seconde extrémité à la première extrémité pour effectuer un mouvement dans la pointe. Le procédé se rapport à l'utilisation d'un tel dispositif pour fixer une ou plusieurs couches de tissu entre elles, pour finalement contribuer à la fusion des couches.
