Abstract: A disposable tissue removal device comprising a cutting element mounted to a handpiece. The cutting element includes an outer cannula defining a tissue-receiving opening and an inner cannula concentrically disposed within the outer cannula. The outer cannula has a trocar tip at its distal end and a cutting board snugly disposed within the outer cannula. The inner cannula defines an inner lumen that extends the length of the inner cannula and terminates in an inwardly beveled, razor-sharp cutting edge. The inner cannula is driven by both a rotary motor and a reciprocating motor. At the end of its stroke, the inner cannula makes contact with the cutting board to completely sever the tissue. An aspiration vacuum is applied to the inner lumen to aspirate excised tissue through the inner cannula and into a collection trap that is removably mounted to the handpiece. The rotary and reciprocating motors are hydraulically powered through a hydraulic circuit.

Abstract: The present invention provides devices for depositing objects into tissue of an animal. The devices include a cannula having a proximal-end and an opposite distal end insertable into tissue and defining an exit aperture. The cannula has a sidewall between the distal and proximal ends and defines a passageway in communication with the exit aperture. A distal retaining tab extends from an inner surface of the cannula and is positioned across at least a portion of the passageway adjacent the exit aperture. The distal tab has a first closed position blocking the passageway and a second open position wherein the tab is urged towards the sidewall to allow an object to pass. The tab is resilient to return to the first position after the object passes the tab. In some embodiments, the invention also includes a proximal retaining tab adjacent the proximal end of the cannula and positionable to block a portion of the passageway.

Abstract: A system and method for providing closed loop infusion formulation delivery which accurately calculates a delivery amount based on a sensed biological state by adjusting an algorithm's programmable control parameters. The algorithm calculates a delivery amount having proportional, derivative, and basal rate components. The control parameters may be adjusted in real time to compensate for changes in a sensed biological state that may result from daily events. Safety limits on the delivery amount may be included in the algorithm. The algorithm may be executed by a computing element within a process controller for controlling closed loop infusion formulation delivery. The biological state is sensed by a sensing device which provides a signal to the controller. The controller calculates an infusion formulation delivery amount based on the signal and sends commands to an infusion formulation delivery device which delivers an amount of infusion formulation determined by the commands.
