A catheter mounted arterial surgical tool has a body with a fluid jet prong extending from a distal end of the body along a prong axis that is parallel to and laterally offset from a body axis. A fluid passage extends through the fluid jet prong to an outlet that points laterally relative to the prong axis. A deflector anvil extends from the distal end of the body along a deflector axis that is parallel to and offset from the body axis. The deflector anvil has a face that faces toward the fluid jet prong and is impinged by a fluid jet discharged from the outlet. A pair of guide wire holes extend from the proximal to the distal end of the body parallel to the body axis for receiving guide wires to enable the body to slide along the guide wires.

A handle assembly for use in conjunction with a surgical cutting device is provided. The handle assembly can generally include two, detachable pieces or housings. The first housing can include electrical and mechanical components for driving a cutting assembly, such as a motor, while the second housing can include a fluid flow path that allows fluid to flow from the surgical site to a location outside of the cutting device. At least a portion of the fluid flow path can extend substantially adjacent to at least a portion of one or more components used to drive the cutting assembly to help manage the heat output of the components. The fluid flow path allows the fluid to exit the device without coming into contact with components like a motor, while also helping to cool the handle assembly. Systems and methods for cutting tissue are also provided.

An apparatus for supporting an extremity during tissue irrigation and debridement and containing and capturing fluid and tissue debris resulting therefrom includes an extremity-supporting base and barrier shroud. The apparatus can be used to control drainage of fluid and tissue debris during irrigation and debridement. The apparatus supports and encloses a patient extremity, such as an arm or a leg. The base has a length, proximal end (i.e., nearest the patient's body), and distal end (i.e., farthest from the patient's body). The base may comprise an open-cell foam that is non-collapsible to provide a support surface with a fixed length. The shroud has a top portion, bottom portion, and shroud drainage opening. The shroud can be selectively moveable between a first position in which the support surface is unobstructed to facilitate placement of an extremity thereon and a second position in the shroud at least partially encloses the extremity.

A surgical handpiece includes a housing gripped by a user; an aspirating flow path member that is accommodated in the housing, and aspirates a liquid; and an aspiration pipe that is held by the housing, and is connected to the aspirating flow path member via interference fitting so as to aspirate the liquid. At least one of the aspirating flow path member and the aspiration pipe includes a sealing portion for realizing the interference fitting, which is bulged toward a mating member of the interference fitting.

The Powerline Communication (“PLC”) systems and methods described allow for bi-directional communication along an AC or DC conductor between a first device and at least a second device comprising a medical device system. Generally, two devices within a sterile field may communicate with each other by PLC or a first device within a sterile field may communicate with a second device that is outside the sterile field by PLC. More specifically, a controller unit may communicate with a saline, or other fluid, pump to achieve a variety of functional purposes. Similarly, a measurement device may share measured data with another device.

A liquid ejecting apparatus includes: an inflow channel to which liquid is supplied; an outflow channel communicated with a nozzle; a liquid chamber formed with a spiral flow channel having a substantially constant cross-sectional area between the inflow channel and the outflow channel and having a given volume; a volume changing portion configured to deform the liquid chamber so as to change the volume of the liquid chamber to a volume smaller than the given volume; and an ejection control unit configured to cause the liquid to be ejected from the nozzle in a pulsed manner by driving the volume changing portion in a state in which the liquid chamber is filled with the liquid.
