Patent number: 8231647Abstract: The present invention relates generally to a catheter having a torque transmitting shaft which retains adequate flexibility. The catheter includes an elongate shaft having an outer surface. In a preferred embodiment, a raised pattern is disposed on the outer surface. Preferably, the raised pattern improves the transmission of torque along the elongate shaft by including a series of bearing points which contact other bearing points along the shaft when torqued.Type: GrantFiled: December 31, 2008Date of Patent: July 31, 2012Assignee: Boston Scientific Scimed, Inc.Inventor: Tracee E. J. Eidenschink

Patent number: 8221350Abstract: The end cap is preferably formed of a relatively high durometer material with an inner surface on an outer surface of the shaft and on an outer surface of the balloon skirt section, and contacts a compression member on the balloon outer surface. The configuration prevents or inhibits failure at the balloon seals which otherwise results from the compression member moving or the balloon pulling off the shaft and out from under the compression member during inflation of the balloon. As a result, the balloon catheter of the invention has an improved consistent burst pressure and/or failure mode.Type: GrantFiled: March 3, 2011Date of Patent: July 17, 2012Assignee: Abbott Cardiovascular Systems Inc.Inventor: John A.

Patent number: 8157146Abstract: An endovascular stapler (100) for securing an endograft to a vessel is disclosed. The stapler has a staple housing (104), an actuating mechanism (148) and an expansion mechanism (126). The staple housing (104) has a plurality of staple cartridges (128) adapted for storing at least one staple (180) therein. The staple cartridges (128) have an exit area (130) for discharging at least one of the staples (180) therethrough. The actuating assembly (148) is adapted for actuating the plurality of staple cartridges (128) to discharge the at least one staple through the exit area. The expansion mechanism (126) is in operative association with staple cartridges (128). The expansion mechanism (126) is operative for pushing the exit area (130) against the endograft when discharging the at least one staple therethrough.Type: GrantFiled: November 16, 2006Date of Patent: April 17, 2012Assignee: Edrich Health Technologies, Inc.Inventors: John K. Edoga, Thierry Richard, Peter Hinchliffe
