Patent number: 10368789Abstract: A medical port has a housing forming an interior with a fluid inlet and a fluid channel extending from the fluid inlet. The housing also has an exterior wall forming at least one radial opening to the interior. In addition to the housing, the medical port also has a resilient valve element within the housing interior configured to control fluid flow through the inlet, and a biasing element movably couplable with the housing. The resilient valve element has a proximate body portion proximate to the radial opening when in the closed mode. The biasing element also has a constraining portion configured to cooperate with the radial opening to contact at least the proximate body portion of the valve element when in the closed mode. The biasing element constraining portion preferably is configured to normally resist radial outward movement of the proximate body portion when in the closed mode.Type: GrantFiled: December 23, 2016Date of Patent: August 6, 2019Assignee: NP MEDICAL INC.Inventors: Todd Chelak, Ian Kimball, Ray Adams, Jeffrey Ransden

Publication number: 20160128729Abstract: A device includes an insertion member having a distal end portion configured to be removably engaged with an implant, and a sheath having an exit portion and defining a lumen. The exit portion of the sheath includes a set of dilation members configured to be moved from a first configuration to a second configuration. The set of dilation members forms a dilation surface when the set of dilation members is in the first configuration and defines an opening when the set of dilation members is in the second configuration. The sheath includes a hinge configured to facilitate movement of the set of dilation members between the first configuration and the second configuration. The distal end portion of the insertion member configured to move within the lumen to convey the implant from within the lumen via the opening when the set of dilation members is in the second configuration.Type: ApplicationFiled: June 20, 2014Publication date: May 12, 2016Applicant: Bioceptive, Inc.Inventors: Shuchi P.

Patent number: 9241698Abstract: An intracorporeal surgical tissue retractor is provided having an anchor selectively deployable in a first tissue not to be retracted and a grasper selectively deployable on a second tissue to be retracted. A longitudinally selectively movable support is threadable through the anchor and attached at a substantially distal end of the movable support to the grasper. A deployment user interface is couplable to the movable support and has a proximal end manipulable by a user extracorporeally and a distal end releasably attachable to both the anchor and the grasper, adapted to intracorporeally deploy the anchor into the first tissue and the grasper onto the second tissue. The user interface includes a first actuator having an anchor positioning tool enabling selective deployment of the anchor in the first tissue, and a second actuator enabling selective opening and closing of the jaws of the grasper.Type: GrantFiled: October 7, 2014Date of Patent: January 26, 2016Assignee: Novatract Surgical, Inc.Inventors: Jeffrey Ransden, Leland Ray Adams, Gregor Weaver, Vincent Mata, III, Adam Lehman

Patent number: 6681971Abstract: Securement arrangement for mounting articles upon a carrying vehicle. The arrangement includes a pair of substantially rigid body members. At least one of the pair of body members has a receiver configured to accept the installation of a fitting member therein. A plurality of resilient fitting members are utilized. Each fitting member is adapted to be installed in the receiver in a plurality of orientations. At least one of the fitting members is configured to present a variable buffering thickness between the rigid body member and a receiving member of a carrying vehicle upon which the securement arrangement shall be installed. The variable buffering thickness is dependent upon an installed orientation of the fitting member in the receiver.Type: GrantFiled: March 8, 2002Date of Patent: January 27, 2004Assignee: Thule Sweden ABInventors: John Laverack, Gregor Weaver, John F.
