摘要:
A hand-held actuator device for releasing into the body from a delivery system a medical prosthesis, like a stent, comprising a frame (10) that acts as a housing, a reel (30) for receiving a wire (8), a manually operable slider (34) mounted to the frame and a one-way connection between the slider and the reel. Actuating the slider causes the reel to wind up the wire and release the medical prosthesis.

The present invention relates to a method and device (1) for releasing into the body from a delivery system a medical prosthesis mounted on the delivery system and held by a constraint (16) in a constrained delivery disposition. The device comprises a first abutment (28) for the delivery system, a second abutment (18) for an elongate element (30) to connect the device to the prosthesis constraint, a track (14) for the second abutment (18) to advance along, from a starting point corresponding to constraint of the prosthesis, to a finishing point corresponding to separation of the prosthesis and constraint (16), ratchet means (38) to advance the second abutment (18) progressively, from the starting point to the finishing point, in a plurality of actuation strokes, and is characterised by a full stroke actuator (24), to advance the second abutment (18) all the way from an intermediate point on said track (14) to said finishing point in one single stroke of the said actuator (24), the intermediate point being selectable by the user within a portion of the track (14) which extends over at least half the length of the track.
摘要:
A percutaneous trans-luminal catheter delivery system for an implant, the system comprising: a catheter shaft with a distal end to carry the implant and a proximal end, and an elongate housing at the proximal end that an operator can grasp when deploying the implant; the shaft having an inner push component which can push on the implant in a distal direction and an outer sheath component which radially surrounds the implant until said deployment of the implant into the bodily lumen, the outer sheath component being capable of being pulled proximally, from the housing, to deploy the implant; the housing being mounted on a proximal end portion of the push component and defining a channel; the housing containing a sheath slitter that is fixedly mounted relative to the length of the channel and that can slit the outer sheath as the outer sheath is caused to move proximally in the channel relative to the slitter.

There is disclosed herein a device (1) for moving an elongate member relative to an. elongate body through which it extends, the device comprising: a housing (10) connectable to the elongate body; a mover (20) associated with the housing and connectable to the elongate member for moving the elongate member relative to the housing and relative to a connected elongate body; and a pre-mover (40) for adjusting an elongate member connected to the mover relative to an elongate body connected to the housing in preparation for moving the elongate member with the mover. There is also disclosed a related surgical apparatus.
