Patent number: 9533108Abstract: Medical needle shield apparatus for covering a needle after use. The medical needle shield apparatus includes a first member, such as, for example, a syringe barrel having a needle mounted therewith. A second member, such as, for example, a shield is mounted with the first member. The shield is movable between a first position whereby the needle is exposed and a second position whereby the needle is covered. A lock is mounted with the barrel such that the shield is slidably movable along an outer surface of the lock. The lock includes a tang that is movable radially outward to fix the shield in the second position.Type: GrantFiled: August 29, 2013Date of Patent: January 3, 2017Assignee: Covidien LPInventors: David J. Salto, Eugene E. Weilbacher

Patent number: 8506533Abstract: A surgical apparatus includes a hub, a closure valve, an internal seal member, and a spring. The hub defines an internal chamber. The closure valve is disposed within the internal chamber and defines an internal bore extending therethrough. The closure valve is movable relative to the hub between a first position, substantially sealing the internal chamber, and a second position, establishing a fluid passage extending completely through the hub. The internal seal member is disposed within the internal bore of the closure valve and is movable relative to the closure valve between a closed position, substantially sealing the internal bore, and an open position, establishing an internal passage, different from the fluid passage, extending completely through the closure valve. The spring is disposed within the internal chamber and is configured to bias the internal seal member towards the closed position, thereby biasing the closure valve towards the first position.Type: GrantFiled: October 31, 2011Date of Patent: August 13, 2013Assignee: Covidien LPInventors: James L Carlyon, David J.

Patent number: 8048039Abstract: A surgical fluid transfer apparatus for passage of fluids includes a hub defining a longitudinal axis and having an internal chamber, an elongated member extending from the hub and a closure valve disposed within the internal chamber. The closure valve is adapted for movement between a first position substantially sealing the internal chamber to prevent passage of fluids and a second position establishing a fluid passage within the hub to permit passage of fluids therethrough. The closure valve includes a valve housing and a seal member. The seal member has an open condition establishing an internal passage different than the fluid passage to permit passage of an access instrument through the closure valve and a closed condition in the absence of the access instrument. The inner wall portions of the valve housing cooperate with the seal member to permit the seal member to assume the closed condition thereof.Type: GrantFiled: September 28, 2007Date of Patent: November 1, 2011Assignee: Tyco Healthcare Group LPInventors: James L. Carlyon, David J. Salto, Eugene Schrader

Publication number: 20080082082Abstract: A surgical fluid transfer apparatus for passage of fluids includes a hub defining a longitudinal axis and having an internal chamber, an elongated member extending from the hub and defining a longitudinal conduit and a closure valve disposed within the internal chamber of the hub. The closure valve is adapted for movement between a first position substantially sealing the internal chamber to prevent passage of fluids and a second position establishing a fluid passage within the hub to permit passage of fluids therethrough. The closure valve includes a valve housing having inner wall portions defining a general tapered internal bore and a seal member at least partially disposed within the tapered internal bore of the valve housing. The seal member defines a general tapered configuration and has an open condition permitting passage of an access instrument through the closure valve and into the longitudinal conduit of the elongated member and a closed condition in the absence of the access instrument.Type: ApplicationFiled: September 28, 2007Publication date: April 3, 2008Inventors: James L. Carlyon, David J. Salto, Eugene Schrader
