Interventional medical device connector and method for using same

摘要

An interventional medical device connector and a method for using same. The interventional medical device connector comprises an implant (1) and a pusher (5). One end of the implant (1) is provided with at least one lock ring (9). The top end of the pusher (5) is provided with at least one locking hole (7). The pusher (5) is provided with at least one control wire (4). The control wire (4) slides along the axial direction of the pusher (5), and the top end of the control wire (4) can reach at least one of the locking holes (7). The control wire (4), the lock ring (9) and the locking hole (7) together form a connection means having a lock-pin structure. Use of this means of connection effectively overcomes the defects of existing threaded connections, reduces risks, and provides convenience of use.

1. A medical assembly comprising an implant and a pusher, wherein:
the implant has a locking ring provided at an end of the implant; the pusher has a locking hole provided at a top end of the pusher, and a control wire that slides along an axial direction of the pusher, with the control wire having a top end which extends through the locking hole; the locking ring is retained inside the locking hole with the control wire extending across the locking hole when the implant is coupled to the pusher by the control wire; and the locking ring is made from a shape memory material such that the locking ring is biased to transition to be positioned against a surface of the implant when the locking ring is dis-engaged from the pusher.
