The upper and lower body portions of the housing define an internal chamber for accommodating the valve member and a central axis for the valve. The generally spherical valve member is seated within the internal chamber of the valve housing and has an axial bore extending therethrough. The valve member is mounted for movement between an open position; wherein the axial bore of the valve member is axially aligned with the inlet and outlet ports of the valve housing, and a closed position; wherein the axial bore of the valve member is out of alignment with the inlet and outlet ports of the valve housing.Type: GrantFiled: December 15, 2006Date of Patent: January 25, 2011Assignee: Axial Technologies, LimitedInventors: Michael Ross Kessell, Paul Neville Adams, Steven Lyle Weir, Henry Bolanos

Publication number: 20100249695Abstract: A trocar assembly that comprises a trocar valve body defining a cavity, the valve body for communicating insufflation fluid therethrough. The assembly also comprises a selectively rotatable valve handle for controlling a flow of said insufflation fluid through the valve body. The rotatable valve handle is elongated and has a first end and a second end. The first end is sized and configured to be rotatably maintained within the cavity and the second end extends outwardly so as to be actuatable by a user. The rotatable valve handle defines a bore therethrough which extends longitudinally from the first end to the second end. The valve body defines an outlet that communicates with the cavity. The rotatable valve handle is rotatable from an open position, in which the bore of the valve is at least partially aligned with the outlet so as permit fluid to pass through the bore, and a closed position, in which the bore of the valve is not aligned with the outlet so as prevent fluid to pass through the bore.Type: ApplicationFiled: February 25, 2010Publication date: September 30, 2010Inventor: Brian Rockrohr

Patent number: 7798991Abstract: A trocar system for endoscopic surgery, cap assembly, and related methods are provided. The cap assembly includes a housing with an opening formed in line with an axis of the housing. The cap assembly also includes a variable opening flexible sealing gland having a stack of valve body sections each including a valve extension extending from a valve ring and having a valve opening and a slit extending between a valve opening and the valve ring. The combination of the individual valve body sections forms a substantially conically shaped iris diaphragm portion of the sealing gland. The iris is positioned to individually and separately receive elongate tools so that when any one of the elongate tools is positioned through the valve opening, a seal is maintained between peripheries of the seal gland surrounding the iris and outer peripheries of the inserted elongate tool.Type: GrantFiled: November 14, 2007Date of Patent: September 21, 2010Assignee: Genico, Inc.Inventor: Rogelio A.

Patent number: 7766878Abstract: An embodiment of the invention includes an entry needle. The entry needle may include a cannula, a needle extending within a lumen of the cannula, and a hub operatively associated with a proximal portion of the cannula. The hub may include a branch in communication with the lumen of the cannula. The needle may be movable between a first position and a second position. In the first position, the needle may prevent communication between an opening in an outer wall of the cannula and the branch. In the second position, the needle may allow communication between the opening in the outer wall of the cannula and the branch.Type: GrantFiled: March 8, 2007Date of Patent: August 3, 2010Assignee: Boston Scientific Scimed, Inc.Inventors: Anthony R. Tremaglio, Jr., Michael S. H. Chu, Tim E. Ward

Patent number: 7744569Abstract: A surgical seal assembly includes a sleeve housing adapted to be operatively connected to a surgical sleeve, a seal housing adapted for releasable mounting to the sleeve housing and having a seal member with inner portions adapted to permit passage of a surgical object in substantial sealed relation therewith, and a manual lock member associated with the sleeve housing. The manual lock member is adapted for movement relative to the seal housing between a first position corresponding to a release position of the seal housing to permit removal of the seal housing from mounting to the sleeve housing and a second position corresponding to a lock position of the seal housing to secure the seal housing to the sleeve housing. The manual lock member is preferably adapted for rotational movement relative to a longitudinal axis of the seal housing to move between the first and second positions thereof.Type: GrantFiled: September 2, 2008Date of Patent: June 29, 2010Assignee: Tyco Healthcare Group LPInventor: Robert C. Smith

Patent number: 7695445Abstract: A three-way stopcock that can be opened/closed in the same manner as conventional operation methods and can reduce stagnated portions of fluid in a fluid flow passage. Out of branch openings, a first branch opening and a second branch opening are arranged on a straight line, and a third branch opening is directed perpendicularly to the line connecting the first and second branch openings. Provided at a flow passage switch portion are a first flow-passage opening and a second flow-passage opening that are arranged on a straight line and a third flow-passage opening that is directed perpendicularly to the line connecting the first and second bran openings.Type: GrantFiled: November 11, 2002Date of Patent: April 13, 2010Assignee: JMS Co., Ltd.Inventor: Takehiko Yuki

Publication number: 20090093752Abstract: A surgical apparatus for positioning within a tissue tract accessing an underlying body cavity includes a seal anchor member comprising a compressible material and being adapted to transition between a first expanded condition to facilitate securing of the seal anchor member within the tissue tract and in substantial sealed relation with tissue surfaces defining the tissue tract and a second compressed condition to facilitate at least partial insertion of the seal anchor member within the tissue tract. The seal anchor member defines a longitudinal axis, and has leading and trailing ends with at least one longitudinal port extending therebetween adapted for reception of an object whereby compressible material defining the at least one port is adapted to deform to establish a substantial sealed relation with the object. The seal anchor member may comprise a memory foam material and may include a plurality of longitudinal ports.Type: ApplicationFiled: October 2, 2008Publication date: April 9, 2009Inventors: Paul D. Richard, Russell Heinrich
