  • Patent number: 10639400
    Abstract: A method for coupling a body conduit to tissue includes engaging an implant about an outer surface of a catheter. The implant receives a bioactive agent having tissue growth properties. The method involves inserting the catheter through the body conduit and into a tissue opening across a resected area, positioning the implant in the resected area, inflating a balloon to anchor the catheter within the tissue opening such that the implant bridges the body conduit and the tissue opening across the resected area, and maintaining the catheter and the implant in vivo to enable the bioactive agent to secure the implant in the resected area to permanently bridge the body conduit and the tissue opening.

  • Publication number: 20080281338
    Abstract: A surgical suture system (1, 21, 41) is illustrated and described. The object, namely to permit simple correction of the suture course or of an incorrect position, is achieved by a suture system (1) with a needle-like applicator (2, 22, 42) having a tip (26, 50) in its front end area, with a surgical suture material (4, 24, 44) provided with barbs (6, 7, 28, 29, 47, 48) which, on one side, preferably point in one direction of action from a reference point (8, 30, 49) and, on the other side, point in the opposite direction of action from the reference point (8, 30, 49) and are designed to block a movement of body tissue (12) away from the reference point (8, 30, 49), and with a sheath (3, 23, 43) whose front end area starts from the rear end area of the applicator (2, 22, 42) and which surrounds the surgical suture material (4, 24, 44).

  • Publication number: 20080200950
    Abstract: Extending from a point, namely the point of rotation (2), of a surgical hook (1), there are at least two curved arms (4, 5) whose free ends (A, B) each have a tip (6, 7) and which are curved in the same direction of rotation. The arms (4, 5) can be introduced into a patient's tissue by turning the hook (1) about the point of rotation (2). The hook (1) preferably comprises absorbable material, and the arms (4, 5) are preferably provided with barbs (8) which point away from the free ends (A, B) of the arms (4, 5). The hook (1) is suitable for wound closure, including in a vertical direction, and also for fixing of implants.

  • Publication number: 20070250147
    Abstract: A surgical implant (10) has an areal base structure (12) and at least one projection (14) which is absorbable or partially absorbable and which is designed to take up at least half the implant's own weight of body fluids. In a preferred embodiment, the projection (14) has an attachment area (16) which is sited on the base structure (12) and which is adjoined by a cylindrical or frustoconical middle part (17), pointing away from the base structure (12), followed by a widening (18) arranged at the end remote from the base structure (12).
