CONNECTION SYSTEM FOR THE DETACHABLE FIXATION OF A HOLLOW CYLINDRICAL COMPONENT AT A RECESS

摘要

To establish an easily detachable connection of a hollow cylindrical component (9), such as a graft, at a recess (2) in tissue, such as a heart or a blood vessel, an annular element (13), a guide element (15) and a spring element (19) are provided, which are secured by way of a suture ring (4) at the body part and at the hollow cylindrical component, and which permit an easily disengagable mutual locking by way of the spring element. To this end, the annular element comprises a groove (14) extending around the periphery thereof, into which the spring element plunges for locking.
