Abstract: A surgical fastener applying device having a handle with a trigger pivotably attached thereto and movable within a trigger plane. The trigger has a bottom portion extending from the handle and a top portion disposed within a housing of the handle. The device has a staple housing with a proximal end attached to the handle, a distal end extending therefrom and a longitudinal axis therebetween. The housing has a firing bar disposed within, and the trigger is coupled to the firing bar. The device has a link member with a first end pivotably attached to the top portion of trigger, the link member has a second end comprising a slidable pin. The pin engages a three dimensional cam path disposed within the housing. The link member follows distal and proximal movement of the top portion of the trigger, and the pin slides perpendicular to the trigger plane to follow the three dimensional cam path.

Abstract: A fastener applying device including a staple housing having a proximal end attached to a handle, a distal end, and a longitudinal axis therebetween. There is at least one fastener within the housing. The device also includes an anvil movable within the staple housing. The anvil has a proximal position and a distal position, wherein when in the distal position a distal end of the anvil extends distal to the distal end of the staple housing by a distance. The device also includes an adjustment nut connecting the staple housing to the handle. Rotation of the adjustment nut changes the distance.

Abstract: A surgical fastener applier having a handle and a fastener housing extending from the handle. The housing contains at least one anvil movable within the staple housing, the anvil has a proximal position and a distal position. When in the distal position a distal end of the anvil extends distal to the distal end of the staple housing. The housing contains a plurality of surgical fasteners each of which in the shape of a loop. At least one of the fasteners is placed around a portion of the anvil when in the distal position. The applier has a first mechanism for moving the anvil distally after a fastener has been deployed, and a second mechanism for moving the anvil distally after a fastener has been deployed. The second means is independent of the first means.

Abstract: The present disclosure relates to devices for introducing a port within a body cavity. The system includes a compressible port that collapses radially for positioning into an introducer that is inserted into an incision. Methods for using the devices are also described.

Abstract: A method for feeding a fastener including the step of providing a device having a housing, at least one fastener within the housing, wherein the fastener is disposed within the housing in a first plane, an elongated actuator disposed within the housing, the actuator comprising a shaft substantially parallel to a longitudinal axis of the housing and rigidly spaced from the fastener in a second plane the actuator comprising at least one radially extending advancer disposed along a length thereof. The method further includes the step of rotating the actuator so to engage the fastener, and longitudinally moving the actuator to advance the fastener.

Abstract: A mechanism for feeding a fastener including a housing having a longitudinal axis and at least one fastener within the housing. The fastener has a crown and at least two legs extending therefrom. The fastener is disposed within the housing in a first plane parallel to the longitudinal axis. The mechanism includes an elongated actuator disposed within the housing. The actuator has a shaft substantially parallel to the longitudinal axis of the mechanism and rigidly spaced from the fastener in a second plane. The actuator has at least one radially extending advancer disposed along a length thereof, and a mechanism for rotating the actuator so that the advancer engages the fastener.

Abstract: A sensing and drainage catheter for use in a cranial site includes a reduced diameter connector so that traditional tunneling techniques may be used with the connector-equipped proximal end of the catheter, rather than the sensor-equipped distal end of the catheter. The catheter includes a drainage lumen and a signal conducting lumen. The signal conducting lumen including a distal sensor for sensing the properties of cerebral spinal fluid and means for transmitting data signals representing those properties in either optical or electrical form to a reduced diameter connector attached to the proximal end of the lumen. A method comprises first accurately locating the distal end of the ventricular catheter in the brain ventricle prior to the catheter being tunneled under the scalp.
