Patent ID: 6984221

Claim:
Device for inosculation of a hollow organ to the skin, of the type of device comprising a transparietal tube, ends of which are attached to collars ( 6 , 8 ) holding the tube, respectively, against the internal wall of the organ (intravisceral collar 8 ) and against the outside surface of the skin (skin collar 6 ), with the intravisceral collar ( 8 ) being constructed so that its shape can be changed by the practitioner to allow the intravisceral collar ( 8 ) to pass inside the organ directly from the outside of the patient's body, with the following characteristics: The transparietal tube comprises at least two parts ( 2 , 4 ), each attached to a collar respectively intravisceral ( 8 ) and skin ( 6 ), the said parts ( 2 , 4 ) of the tube being fitted so that they are mobile for relative changes axial in position that are not spontaneously reversible, the said distal part ( 4 ) of the tube, attached to the intravisceral coller ( 8 ), comprising means of immobilisation ( 10 , 12 , 26 ) that can be used from the outside towards the inside of the tube to enable the practitioner to make the said changes in position; Such that the practitioner can adapt the length of the tube ( 2 , 4 ), in both directions, according to the cumulated thickness of the fascia ( 1 ) of the patient crossed, both at the time and after the tube ( 2 , 4 ) is installed on the patient, and such that the variation in the length of the tube is taken up inside the thickness of the fascia ( 1 ) of the patient that it crosses; The relative mobility between the two parts ( 2 , 4 ) of the transparietal tube is obtained by screwing ( 26 ), with the distal part ( 4 ) of the tube being provided with a non circular axial opening ( 18 ) that constitutes a nesting organ, in order for it to be rendered immobile in the rotational direction by the practitioner using a specific tool ( 16 ), that can be introduced inside the said axial opening ( 18 ) and that comprises at least one area of complementary cross-section.
