  • Patent number: 11006944
    Abstract: This disclosure relates to a surgical device configured to deliver implants and a method of repairing damaged tissue, such as meniscus tears. One exemplary surgical device includes a cannula and a pusher moveable within the cannula to deploy a plurality of implants. Movement of the pusher in the distal direction deploys a distal-most implant and moves any additional implants distally within the cannula. Thus, multiple implants can be loaded into the cannula and deployed using one pusher. The disclosed arrangement is easy to use and has fewer component parts compared to prior devices, which in turn increases the ease of manufacture and reduces cost.

  • Patent number: 10966727
    Abstract: A device for delivering an implant (e.g., an embolic micro-coil) to a vascular disorder of a patient includes a delivery pusher, a moveable element, and first and second elongate members. The delivery pusher defines a lumen between its proximal and distal ends. The moveable element (e.g., a floating tube or a floating coil) defines a passageway therethrough and is disposed within the lumen of the delivery pusher. The first and second elongate members (e.g., core wires) are also disposed within the lumen of the delivery pusher. A portion of each elongate member passes through the passageway of the moveable element. Movement of the first elongate member in a first direction (e.g., retraction of the first elongate member from a locked to an unlocked configuration) causes a time-delayed or lost motion movement of the second elongate member in the same (i.e., first) direction, which releases the implant from the delivery pusher.

The fasteners may also be mounted on a guide rod or mandrel that passes through a through-hole of the head and the coil body. The shaft may also include a guiding element that contacts and stabilizes the coil body as the fastener is deployed from a distal end of the shaft. When the head approaches and contacts the guiding element, the guiding element may deflect to permit the head to pass.

  • Patent number: 10849630
    Abstract: A reposable surgical clip applier includes a handle assembly, a shaft assembly releasably engagable with the handle assembly, and a clip cartridge assembly releasably engagable within the shaft assembly. The handle assembly includes at least one handle, a proximal drive member, a proximal pusher, and a handle spring assembly configured to bias the handle(s) towards a spaced-apart position. When the reposable surgical clip applier is assembled, the proximal drive member is positioned proximally adjacent an inner drive assembly of the shaft assembly such that movement of the handle(s) towards an approximated position actuates a jaw assembly of the shaft assembly. When the reposable surgical clip applier is assembled, the proximal pusher is positioned proximally adjacent a distal pusher of the clip cartridge assembly such that movement of the handle(s) towards the spaced-apart position loads a distal-most surgical clip from the clip cartridge assembly into the jaw assembly.

  • Patent number: 10779944
    Abstract: The invention provides a heart valve leaflet capture device (250) comprising a cardiac catheter probe having a proximal end for manipulating the device (250) and a distal end terminating in a transvalve element (256). The transvalve element (256) is configured to pass through a heart valve generally parallel to a longitudinal axis of the catheter and includes two or three leaflet gripping elements (252). The leaflet gripping elements (252) are individually movable by operation of an associated actuating mechanism (260) between a radially retracted position, in which they are withdrawn with respect to the transvalve element (256), and a capture position, in which they diverge outwardly at an acute angle from the transvalve element (256). In the capture position, each leaflet gripping element (252) defines a convergent capture zone that is directed towards the edges of a target valve leaflet and in which the target valve leaflet may be captured.
