Systems for insufflation and recirculation of insufflation fluid in a surgical procedure include a control unit having a fluid pump, a supply conduit, a return fluid conduit and a pressure-controlled valve. The pressure-controlled valve is in fluid communication with an insufflation gas supply, the supply conduit and the return conduit and is adapted and configured to respond to pressure control signals to adjust position and thereby system flow parameters, to reduce entrainment of air from the surrounding environment, and to increase the concentration of insufflation gas in an operative space, and/or to reduce an overpressure condition in the operative space.

System and method for improved gas recirculation in surgical trocars with pneumatic sealing

Reinforcing lumen rings are configured and adapted for use in conjunction with a circular endoscopic stapling instrument having a staple cartridge assembly and an anvil assembly. The reinforcing lumen rings maintain anastomotic lumen, e.g. as formed by the circular endoscopic stapling apparatus, in an open condition. The reinforcing lumen rings can include an annular ring having an outer terminal edge and an inner terminal edge, the outer terminal edge having a diameter which is substantially equal to an outer diameter of the staple cartridge assembly and the inner terminal edge having a diameter which is substantially equal to an inner diameter of the staple cartridge assembly.

Annular support structures

A system for facilitating insufflation and recirculation of fluid during a laparoscopic surgical procedure that includes a trocar, an insufflator for delivering insufflation fluid to the abdominal cavity of a patient through the trocar, a pump for delivering pressurized fluid to a supply plenum of the trocar through a supply line to create a fluid seal within the trocar and for receiving spent fluid from a return plenum of the trocar through a return line, a bypass line for connecting the supply line to the return line under certain pressure conditions, a back pressure control valve positioned within the bypass line and a dump valve in communication with the supply line for releasing pressurized fluid out of the system when an over-pressure condition is sensed.

System for surgical insufflation and gas recirculation

An access device adapted and configured to be inserted through a natural biological orifice, and related surgical methods are provided. The access device includes a body, a nozzle means and means for delivering a pressurized flow of fluid to the nozzle means. The body is configured and dimensioned to be inserted through a natural bodily orifice and has proximal and distal end portions and defines at least one lumen therethrough to accommodate passage of one or more surgical instruments. The nozzle means is operatively associated with the body for directing pressurized fluid into the lumen to develop a pressure differential in an area within a region within the lumen to form a fluid seal around the one or more surgical instruments passing therethrough.

Endoluminal and transluminal surgical methods and devices

A therapeutic compression apparatus having a primary wrap, a foot wrap and a stirrup is provided. The primary wrap encircles a first portion of a leg and applies compression thereto. The foot wrap encircles at least a portion of the foot and applies compression thereto. The foot wrap may be integrated with the stirrup, detachably connected or provided separately. The compression apparatus may be configured such that one or more bladders are provided therein. The compression apparatus may include a pressure gauge and pump for controlling an amount of pressure applied to the treatment site. A bladder assembly with a number of fluid bladder configurations is also provided for use within a compression apparatus. The bladder may be configured to provide a gradient pressure profile to the treatment site when filled.

Therapeutic compression apparatus

A system for insufflation and recirculation of insufflation fluid in a surgical procedure. The system includes a control unit having a fluid pump, a supply conduit, a return fluid conduit and a pressure-controlled valve. The fluid pump is adapted and configured to circulate insufflation fluid through the system. The supply conduit is in fluid communication with an output of the fluid pump and configured and adapted for delivering pressurized insufflation fluid to an output port of the control unit. The return conduit is in fluid communication with an input of the fluid pump for delivering insufflation fluid to the fluid pump and is configured and adapted for returning insufflation fluid from an input port of the control unit. The pressure-controlled valve is in fluid communication with the supply conduit and the return conduit, and is adapted and configured to receive a control signal and respond to the control signal by opening, thereby fluidly connecting the supply conduit and the return conduit with one another.

A compression garment includes a backing member with a proximal end portion and opposed distal end portion. The backing member is configured to be disposed about at least a portion of a lower leg between calf and heel and has an inner surface to be disposed facing the lower leg, and an opposite outer surface. The garment further includes at least one compression bladder disposed within the backing member configured to compress at least a portion of the lower leg to augment venous return flow in the lower leg, an elevation member operatively coupled to the backing member and configured to elevate the heel from an underlying support surface and at least one support member disposed along a portion of the elevation member and along a portion of the backing member to retain the elevation member in a desired position with respect to the backing member to elevate the heel.
