DEVICE FOR PREPARING A HOLE FORMED IN A BODILY WALL AND SYSTEM FOR MAKING AN ANASTOMOSIS BETWEEN A BODILY WALL AND CONDUIT

摘要

The present invention relates to a system (SP) for preparing a hole (O) formed on a bodily wall (P), comprising: - a support body (1) defining a longitudinal axis (X) and having a proximal portion (1 a) and a distal portion (1 b) suitable for being inserted through the hole (O); - outer clamping elements (22) that can be deployed in a corolla relative to the support body (1) and are capable of covering portions of an annular surface (S) of said wall (P), and; - stressing means formed to tighten and juxtapose said outer clamping elements (22) on said body (1 ) in order to gradually deform said annular surface (S) to shape, on said wall (P), a tubular portion (T) extending along the longitudinal axis (X) and to form an anchoring clamp formed from said outer clamping elements (22).
