A system for inserting a cannulated tissue anchor during endoscopic surgical procedures. The system incorporates an elongated generally cylindrical tissue anchor having a plurality of barbs outwardly extending from its body and a transverse head situated at its proximal end. The head is elongated along a major axis which is misaligned relative to the rows of barbs on the body of the tissue anchor in order to enhance retention of the anchor within selected tissue. The anchor may be inserted during an endoscopic surgical procedure by a single-handed operation utilizing an instrument having a longitudinally slidable needle for guiding the anchor into place and a longitudinally slidable push rod for pushing the anchor along the needle. The system incorporates a package/loading device to facilitate the assembly of a cannulated tissue anchor with the inserter, the package/loading device being provided with a means for guiding the inserter needle through the axial bore of the tissue anchor.

Surgical tubing cassette

An irrigation/aspiration pump system capable of operating in a plurality of different modes suitable for a variety of different endoscopic surgical procedures. The irrigation/aspiration pump system operates with a selected one of a plurality of tubing sets, each tubing set being adapted to provide irrigation and aspiration for a particular surgical procedure and coded to define the type of procedure for which the tubing set is designed. Each tubing set is adapted to be received by the irrigation/aspiration pump console in a way which enables the code associated with the tubing cassette to be automatically read by a code detecting means associated with the system. The code detecting means supplies appropriate control signals to different parts of the irrigation/aspiration pump system in order to assure that the parameters with which the system will be operating, when the chosen tubing set is being used, are those for which the tubing set is designed. A simplified one-piece cassette housing is utilized to retain a plurality of flexible conduits within predetermined positions relative to each other and relative to associated components of the pump system console.
