SYSTEM FOR JOINING TWO BLOOD VESSELS
First Claim
1. A system for bringing two blood vessels (Vs) into abutment, the system comprising at least two clamps (Pc), each clamp comprising:
- two substantially identical tabs (11, 12), means (20) for pivotally mounting said two tabs (11, 12) relative to each other about a pivot axis (21), said pivot axis (21) being situated substantially in the proximity of respective middle portions (13, 14) of the two tabs, thereby defining on each of the tabs first and second portions (111, 112;
211, 212) situated on either side of a first plane (P1) containing said pivot axis (21) and substantially perpendicular to the general plane of at least one of the two tabs;
means (30) for applying two respective opposing resilient forces on the two first tab portions (111, 112) so that the two free ends (15, 16) of these two tab portions (111, 112) tend to move apart from each other and, correspondingly, the free ends (17, 18) of the two second tab portions (211, 212) tend to come into contact with each other; and
a through hole (260) made in one of the two tabs along an axis substantially parallel to said pivot axis (21), said through hole being cylindrical and of polygonal cross-section;
said system further including a rod (260) of longitudinal axis (270) and having a cross-section that is complementary to the cross-section of the through hole, said rod being engaged in the two respective through holes (250) of the two clamps, wherein a portion of said rod extending between the two clamps possesses two moments of inertia of different values in two mutually orthogonal directions, one of which is perpendicular to the first plane (P1), the smaller value moment of inertia being the moment of inertia defined along the direction that is perpendicular to said first plane (P1).

Abstract
A system for bringing two blood vessels into abutment includes two clamps Pc and a rod 260 connecting the two clamps together by being engaged in two through holes 250 made respectively in the two clamps, a portion of the rod lying between the two clamps possessing two moments of inertia Mi1, Mi2 of different values along two mutually orthogonal directions, one of which is perpendicular to the first plane P1, the smaller value moment of inertia Mi1 being that defined substantially along the direction that is perpendicular to the first plane P1. The system is applicable to bringing two blood vessels into abutment, in particular for the purpose of suturing them.
