摘要： 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.

摘要： 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.

摘要： A pressure sleeve assembly and a method of its use in a fluid injection system are disclosed. The pressure sleeve assembly includes a longitudinal base member, an endplate associated with the longitudinal base member, a fixed or freely removable door, a cylinder and a pivotal arm coupling the cylinder to the longitudinal base member. The pressure sleeve assembly includes properties that increase the ease of use and maintenance of the assembly so as to reduce the effort required by the user and increase the biosafety aspect of the assembly. In addition, the pressure sleeve assembly includes properties that reduce the amount of effort required by the physician prior to and during use of the system as well as properties that increase its range of applications.

摘要： A dual port syringe has an upper port for connection to a fluid reservoir and a lower port for delivery of the medical fluid under pressure to a patient. A first valve is connected between the fluid reservoir and the upper port, and second valve is connected between the lower port and the patient. During a fill operation, a piston is moved within the syringe to drawn fluid from the reservoir into the syringe through the upper port. During injection operation, the piston moves in an opposite direction to force fluid out of the syringe through the lower port.
