Abstract: An anastomotic device, particularly a positioning device (24) extending along a longitudinal axis (30) comprises a first component, or proximal component (26) and a second component, or distal component (28). The proximal and distal components are suitable to lock an elastic ring (52) in a deformed configuration therebetween. The proximal component (26) has a substantially cylindrical outer structure with a cavity (32) for receiving a proximal end (52a) of the elastic ring (52). The distal component (28) comprises a head (42) and a stem (44) developing along the longitudinal axis (30). The head (42) has a cone or truncated-cone shape.

Abstract: The present invention relates to an anastomotic device (10) comprising a first ring (20) having a first contact surface (21) and a second ring (30) having a second contact surface (31). The rings (20, 30) are suitable to be approached in the axial direction (X) such as to move said contact surfaces (21; 31) towards each other. The anastomotic device is characterized in that the contact surfaces (21, 31) have an undulated shape relative to a plane (?) perpendicular to the axis (X) of the rings (20, 30). According to another aspect thereof, the invention also relates to an apparatus (60) for the implantation of the anastomotic device (10). According to a further aspect thereof, the invention relates to a kit comprising an anastomotic device (10) and an apparatus (60) for the implantation of the same.

Abstract: An anastomotic device (10) is suitable for approximating and keeping close to each other a first tissue portion (12) and a second tissue portion (14) intended to form an anastomosis. The anastomotic device (10) comprises an abutment portion (18) suitable for the abutment against a surface of the first tissue portion (12) and a locking portion (20) suitable for being placed opposite the abutment portion (18) with respect to the first and second tissue portion (12, 14). The locking portion (20) and the abutment portion (18) are mutually connectable through the first and second tissue portions approximated, to keep them connected. The anastomotic device (10) is suitable for being connected to a guide means comprising at least one guide wire (A, B).

Abstract: A positioning device for deploying at least one locking portion (20) of an anastomotic device (10) for drawing together a first tissue portion (12) and a second tissue portion (14) to be connected by means of anastomosis is suitable for sliding along a guide means comprising at least one guide wire (A, B) and comprises an elongated structure (50). A head (52) of the positioning device is suitable to be interference-inserted on a distal end of the elongated structure (50). The head (52) comprises elastic tabs (54) extending from a proximal end of the head and at least one channel (56) suitable for receiving a guide wire. The head (52) comprises a distal end defining a thrust surface (58) for a locking portion (20) of the anastomotic device (10).

Abstract: A device for drawing tissues together and creating an anastomosis comprises a main guide wire (66, 86) suitable to receive and draw anastomotic devices (10; 16; 24) in order to draw together portions (A; B) of tissues to be joined by means of anastomosis. The main guide wire (66, 86) is suitable to be shaped like an open ring crossing the portions (A, A?; B, B?) of tissues to be joined by means of anastomosis (66, 86), wherein the ends of the main guide wire (66, 86) are different and distinguishable from each other. The main guide wire (66, 86) has a tubular or hollow structure suitable to house at least one needle for a push or radiofrequency perforation of the tissues.

Abstract: An anastomotic device, particularly a circular stapler (10), comprises a handle (12) and a stem (14). A channel suitable to receive a guide wire at least partially develops along the length of the stapler. The stem (14) is made of a flexible material, such as to facilitate reaching the site requiring anastomosis. The circular stapler (10) comprises an anvil (16) suitable to be introduced on the free end of the stem (14). The anvil (16) comprises a channel (22) suitable to receive a guide wire (66) and extending along the anvil, and a portion (20) suitable to act as a striker against the wall of one of the portions (A; B) of the tissues to be joined.

Abstract: A device for manipulating body tissue comprises a base structure and at least one tubular member having a proximal end and an orientable distal end that defines a seat for supporting a surgical instrument, in which the tubular member is connected to the base structure. An actuation mechanism is suitable for orientating the distal end of the tubular member to take it into certain operative configurations. The actuation mechanism is also connected to the base structure. Means are also foreseen for the connection of the base structure to a distal end portion of an insertion tube of an endoscope or laparoscope, so that the actuation mechanism and the tubular member are arranged outside the insertion tube. The tubular member interacts with the actuation mechanism so that a movement of an actuation portion of the tubular member with respect to the base structure leads to the orientation of the orientable end.
