Abstract: A pump system including a pump, an inflow cassette and an outflow cassette. The inflow cassette has a damping flexible membrane covering a damping region configured to dampen pressure pulsations in washing fluid passing through the damping region. The pump has a plurality of individually actionable pressing members that can each be individually actuated to pinch one of a plurality of suction tubes of the outflow cassette to at least partially prevent fluid flow through the one of the plurality of the suction tubes.

Abstract: A surgical pump system arrangement receives an inflow cassette and provides fluid flow to a surgical site in a joint of a patient. The arrangement calculates load coefficients for a pressure loss curve based on an identified inflow cannula and an identified endoscope utilized therewith. The arrangement determines if the cannula is disposed at a surgical site and if adequate fluid flow is provided. Further, the arrangement determines if the inflow cannula and endoscope are properly identified. The arrangement integrates with an identified or unidentified surgical device to adjust pump operation when the surgical device is operating. The arrangement maps actuators disposed on a surgical handpiece or footswitch to control operation of the pump system, including providing suction to an outflow path of a surgical device that is not operating. The arrangement also determines when an inflow pump cassette is not properly inserted into the pump.

Abstract: An in-joint pump and control device comprising a pump and an in-joint sensor. The pump is configured to convey fluid to a body joint surgical site. The pump has an algorithm associated therewith to make calculations and to assist in controlling the operation of the pump. The in-joint sensor is operatively associated with the pump by at least a communication member. The in-joint sensor comprises a sheath, an integration member attached to the sheath, a pressure sensor connected to the integration member, and a temperature sensor adjacent the sheath. The pressure sensor is adapted to provide pressure information to the pump via the communication member. The temperature sensor is also adapted to provide temperature information to the pump via the communication member.

Abstract: An inflation system includes a bladder incorporated into an article of outdoor gear or apparel. The bladder is incorporated into the article of outdoor gear and apparel so as to provide insulation to a user. The inflation system includes a gas canister that includes a reservoir of dry gas. A valve mechanism allows the dry gas to be used to selectively inflate and deflate the bladder to provide a desired amount of insulation.

Abstract: A fluid delivery system comprising a first bladder having a first inlet and a first outlet, the first bladder configured to contain liquid, a second bladder capable of being pressurized by inflation and having a second inlet, the second bladder being formed adjacent to the first bladder, such that the first bladder and the second bladder are integrated to form a pressurized fluid reservoir.

Abstract: A lightweight, gas-filled, highly insulative material is incorporated into an article of outdoor gear or apparel (e.g., a camping pad). The insulative material has a layered cellular structure that can be filled with an insulative gas (e.g., air or argon). The insulative material includes two or more layers of cells, which improves insulation (compared to a single layer) by reducing convection for a given thickness. Increasing the thickness without substantially increasing convection results in a better insulator and an improvement in the ability to retain heat.

Abstract: The present invention is directed to a lightweight, gas-filled, highly insulative cellular structure and methods for manufacturing the cellular structure. The cellular structure can be incorporated into outdoor gear and apparel to make the outdoor gear or apparel warm, while still maintaining a desired thinness and flexibility. The insulative article takes advantage of the superior insulative properties of dry gases and preferably highly insulative gases such as argon. In addition, the size and shape of the cells in the cellular structure are selected to minimize convection.
