Abstract: Provided for may be a pump failsafe apparatus for use with a pump motor, the pump failsafe apparatus comprising a foot pedal configured to generate a first signal when depressed and a second signal when released. The apparatus may comprise a power supply having an internal logic controlled power switch, the power supply in electrical communication with at least the pump motor, wherein the internal logic controlled power switch includes an active state (ON) and an inactive state (OFF). The apparatus may further include an overspeed detector, an under voltage detector in electrical communication with at least the power supply, the under voltage detector configured to measure a logic voltage, and a pump cartridge detector.

Abstract: Systems, apparatus and methods for removing tissue of various densities from a surgical site in a minimally invasive manner are provided. The invention may include a fine stream of sterile saline, coupled with a suction effect to cut and remove tissue. A power console may be coupled with a handpiece. The power console may utilize an electric motor, thereby transmitting pressurized sterile saline through a high-pressure tube. The distal end may deliver the saline across a window as a high velocity jet stream which, when coupled with the pressure gradient, pulls and then cuts the target tissue into the cutting window and removes it. The tissue and waste saline may then travel down an evacuation lumen to a waste container. By adjusting pressures, tissue types of various densities may be debrided while minimizing disturbance of surrounding tissue.

Abstract: Provided for may be a motor speed control apparatus for use with a piston pump. The piston may be adapted to create a plurality of compressions and the piston may have a compression path and a decompression path. Further, the piston cylinder may include a proximal end, a distal end, and a piston length. The piston cylinder may have a proximal threshold position and a distal threshold position. In an embodiment, the apparatus includes a proximal and a distal hall effect sensor. The apparatus may comprise a computer, wherein instructions instruct the piston to decelerate at the distal threshold position during the compression path and the proximal threshold position during the decompression path, and/or wherein the computer executable instructions instruct the piston to accelerate at the distal threshold position during the decompression path and the proximal threshold position during the compression path.
