Publication number: 20080097296Abstract: A removable hub and/or manifold structure, assembly, and methods, and medical devices including such hub and/or manifold structures. For example, a hub and/or manifold assembly that is adapted and configured to be removably attached to a shaft of an elongated medical device. The hub assembly can include a hub having a proximal portion and a distal portion, and a mechanical connection structure including a first body portion and a second body portion. The first and second body portions can be removably fastenable together about the distal portion of the hub and the proximal portion of a shaft to connect the hub to the shaft. Elongated medical devices including such a removable hub assembly and methods of attaching a removable hub assembly to a medical device are also disclosed.Type: ApplicationFiled: August 16, 2006Publication date: April 24, 2008Inventor: Henry Pepin

Patent number: 7297302Abstract: A tubing assembly for manufacture for a catheter of the type having an inner tubular member defining a lumen, an outer tubular member surrounding said inner member, and a support member mounted between the tubular members to provide rigidity to the flexible catheter. The support member comprises a high tensile strength wire braid, and in the preferred embodiment comprises a stainless steel wire braid which has been tempered or hardened. This higher tensile strength affords significantly greater kink resistance to the flexible catheter. One wire braid has a tensile strength in the range of 300 to 425 kpsi and a braid density of approximately 40 pic. The high tensile strength wire braid has the disadvantage of tending to flare out at its free ends. Therefore, means are provided for preventing the flaring of the wire braid during manufacture of the tubing assembly. One means includes adhesive applied over the free ends. Another means includes a restraining sleeve applied over the free ends.Type: GrantFiled: December 4, 2002Date of Patent: November 20, 2007Assignee: Boston Scientific Scimed, Inc.Inventors: Todd A. Berg, Jason A. Galdonik, Henry Pepin, Brian Scovil

Publication number: 20050283135Abstract: The present invention relates generally to catheters for performing medical procedures including percutaneous transluminal coronary angioplasty. More particularly, the present invention relates to guide catheters, diagnostic catheters and balloon catheters with an improved shaft design. In a preferred embodiment, the present invention includes a catheter shaft comprising an elongate support member having an outer surface, the elongate support member preferably defining a lubricious liner; a first layer disposed over the lubricious liner, a second layer disposed over the first layer, a third layer disposed over the second layer, a fourth layer disposed over the third layer, and a fifth layer disposed over the fourth layer. In preferred embodiments, the first and third layers comprise an ultraviolet-curable epoxy which is cured to desired degrees at select axial locations on the shaft to provide desired stiffness.Type: ApplicationFiled: August 25, 2005Publication date: December 22, 2005Inventor: Henry Pepin

Patent number: 5674208Abstract: An intravascular flexible catheter of the type having an inner tubular member defining a lumen, an outer tubular member surrounding the inner tubular member, and a metallic support member situated between the tubular members to provide rigidity to the flexible catheter. In the preferred embodiment the support member comprises a stainless steel wire braid which has been tempered or hardened to give it a significantly higher tensile strength than the prior art annealing process. This higher tensile strength affords significantly greater kink resistance to the flexible catheter as the lumen size is increased and the wall thickness is decreased.Type: GrantFiled: June 8, 1995Date of Patent: October 7, 1997Assignee: SciMed Life Systems, Inc.Inventors: Todd A.
