  • Patent number: 8221440
    Abstract: An introducer and method for delivering a prosthetic fabric into a patient. The introducer includes a delivery tube having a distal end adapted to be inserted into the patient and a lumen that receives the prosthetic fabric. A loader may be provided to reconfigure the prosthetic fabric from a first configuration to a collapsed configuration and/or to insert the collapsed fabric into the lumen of the delivery tube. A plunger may be provided to push the prosthetic fabric through the delivery tube and into the patient. The loader and plunger may be combined in a dual-purpose component that is reversible to either load the fabric into the delivery tube or push the fabric through the delivery tube.
    Type: Grant

  • Patent number: 5941851
    Abstract: A suction and irrigation handpiece is disclosed having a trigger that cooperates with a locking mechanism to lock the trigger into one a plurality of preselected angular positions. The trigger has a plurality of grooves on an inner surface that removably couple with a tooth of the locking mechanism. The locking mechanism includes a shaft rotatably connected through the housing, a locking arm connected to the shaft, and the tooth at the far end of the shaft. The electrical connections between batteries and a motor in the handpiece also are arranged to facilitate manufacture and uniformly energize the pump at a preset position of the trigger. The handpiece thus has a first conductive lead connected between one pole of the battery and a contact port that is relatively far from the trigger pivot, and a second conductive lead is connected between one port of the motor and the contact port. These two leads form an open circuit at the contact port that may be closed by a conductor connected to the trigger.

  • Patent number: 5792108
    Abstract: A self-priming pulsatile surgical irrigation device is disclosed. The irrigation device comprises a housing, a variable volume pumping chamber liquid pump contained within the housing, and a self-priming valve system operatively associated with the liquid pump. The self-priming valve system, which facilitates the priming of the device, includes a valve housing, a liquid inlet to admit liquid into the valve housing and a liquid outlet to emit liquid from the housing. The housing is configured to define a flow path that directs liquid from the liquid inlet into the pumping chamber. The flow path ensures that the pumping chamber is maintained full during operation of the pump.
