Abstract
A device for end-to-side anastomosis of body ducts comprising a coupling (2) which can be positioned on a side wall (3a) of a first duct (3) and connectable to a second duct (4) in order to create a fluid communication between the first (3) and second duct (4), and means of restraint (5) to firmly and preferably removably attach the coupling (2) to said first duct (3). The device (1) also comprises at least one membrane (6) removably positioned between the coupling (2) and side wall (3a) of the first duct (3) to prevent or allow the fluid communication between the first (3) and the second duct (4).
Claims18
A device for end-to-side anastomosis of body ducts comprising:
- a coupling (2) which can be positioned on a side wall (3a) of a first duct (3) and connectable to a second duct (4) in order to create a fluid communication between the first (3) and second duct (4), wherein said coupling (2) comprises a saddle-shaped portion (7) which can at least partially overlap the side wall (3a) of said first duct (3) and including an opening (8) to create a fluid communication between said first (3) and said second duct (4);
- means of restraint (5) for attaching the coupling (2) to said first duct (3), wherein the means of restraint (5) act with a clamping movement for anchoring to the wall (3a), said means of restraint (5) comprising at least two elements (9, 10) that are elastically deformable so as to at least partially encircle said first duct (3) and to attach said coupling (2) to said first duct (3), wherein each elastically deformable element (9, 10) comprises a fastener (11) for attaching the coupling (2) to said first duct (3), each said fastener (11) comprising at least one hook (12) to only partially perforate the side wall (3a) of the first duct (3) and attach itself to the side wall (3a) of said first duct (3).
A device for end-to-side anastomosis of body ducts comprising:
- a coupling (2) which can be positioned on a side wall (3a) of a first duct (3) and connectable to a second duct (4) in order to create a fluid communication between the first (3) and second duct (4), wherein said coupling (2) comprises a saddle-shaped portion (7) which can at least partially overlap the side wall (3a) of said first duct (3);
- a conduit (14) connected to said saddle-shaped portion;
- means of restraint (5) for attaching the coupling (2) to said first duct (3), wherein the means of restraint (5) act with a clamping movement for anchoring to the side wall (3a), said means of restraint (5) comprising a series of hooks (22) positioned at two sides of the saddle-shaped portion (7), the hooks (22) being connected at one end to a ring (23) that is slidable on the conduit (14) and the hooks (22) passing through slots (24) in the saddle-shaped portion (7), terminating with curved ends (25), normally open and designed to grip the wall (3a) of the duct (3) in their closed configuration.
