Publication number: 20110301623Abstract: A surgical system includes a first instrument defining a first channel and a second instrument receivable by the first channel. The second instrument defines a second channel. A valve coupled to the first instrument controls fluid flow through the first channel, such that impedance of fluid flow through the first channel is substantially the same without the second instrument received in the first channel and with the first channel partially blocked by the second instrument. In another aspect, a surgical apparatus includes an outer member and an inner member received within the outer member to define a first channel therebetween. The inner member houses an optical lens and defines a second channel for receiving a surgical instrument. The first and second channels are configured such that a pump having an inflow rate of up to about 0.7 L/min connected to the second channel can maintain fluid pressure inside an organ.Type: ApplicationFiled: August 18, 2011Publication date: December 8, 2011Applicant: SMITH & NEPHEW, INC.Inventors: Cemal Shener, Christopher R. Newell, Petter Hedstrom, Kenneth W. Krause

Publication number: 20110196314Abstract: A fluid conduit connector assembly includes a connector having a body with an inner surface defining a fluid channel. The connector also includes an inlet region for flow of fluid into the fluid channel, and an outlet region for flow of fluid from the fluid channel. The connector further includes an axial alignment member outward of the body, and a pair of flexible tabs arranged generally circumferentially of the alignment member and outward of the body. The connector can be configured as a day-side connector, transfer member with check valve, and/or patient-side connector. An implementation includes a day-side connector, a patient-side connector, and a transfer member, each of which has a pair of flexible tabs. The pairs of tabs are configured such that the transfer member releasably couples the day-side and patient-side connectors. A method for aseptically connecting a fluid conduit is also disclosed.Type: ApplicationFiled: April 18, 2011Publication date: August 11, 2011Applicant: SMITH & NEPHEW, INC.Inventors: Chad C. Smutney, P. Spencer Kinsey, John M. Polidoro, Petter Hedstrom, Gregory Melville, Timothy J. Morrill, Richard D. Nelson

Patent number: 7604610Abstract: A fluid flow device includes a housing configured to releasably mate with a surgical control unit for controlling fluid flow during a surgical procedure. First and second ports measure fluid pressure within a fluid path provided within the housing. The fluid flow device includes a restrictor for restricting fluid flow at a restriction location along the fluid path. The first port is located upstream of the restriction location and the second port is located downstream of the restriction location. A fluid pump is provided within the housing.Type: GrantFiled: June 13, 2006Date of Patent: October 20, 2009Assignee: Smith & Nephew, Inc.Inventors: Cemal Shener, Kenneth W. Krause, Petter Hedstrom, Brian J. Loreth
