  • Patent number: 11944291
    Abstract: A wound closure system and a method of reducing the size of an open wound are disclosed. A suture line is sutured through body tissue adjacent an open wound, the suture line sutured so as to pass into the body tissue at an entry point and exit at an exit point, the suture line including a plurality of barbs extending outwardly at an acute angle with respect to a surface of the suture line. A biasing member applies a continuous pulling force on the suture line for stretching the body tissue toward the open wound, wherein the biasing member is configured to take up any slack of the suture line during stretching of the body tissue and keep the suture line taut.

  • Patent number: 7566326
    Abstract: A injection system having a syringe body which defines a pumping chamber. A syringe plunger is located in the pumping chamber and is adapted for reciprocal motion within the pumping chamber. The syringe plunger includes a capture member projecting outwardly in a proximal direction. An actuating shaft is coupled to the syringe plunger and is movable through the syringe body to control movement of the syringe plunger. The capture member is adapted to flex radially outwardly when contacted by the actuating shaft to form a releasable engagement with the actuating shaft when the actuating shaft and the capture member are in an engagement position. A release actuator is disposed proximal to the syringe body, and the capture member releases the actuating shaft upon engagement with the release actuator.
