Patent number: 8257279Abstract: Medical devices for navigation through anatomy, including guidewires, which may have a core wire, a slotted tubular member, or both. Embodiments may have coils, including non-circular cross-section edge-wound marker coils, extended coil tips, and soldered or glued mesial joint coils. Core wires may have a step, ridge, or taper at the joints to the tubular member, and may be flattened at the distal tip. Radiopaque material may be located inside the tubular member, and the distal tip may be heat treated to make it shapeable. Additional tubular members or coils may be used concentrically or in line and may enhance flexibility, provide radiopacity, reduce friction, or reduce material or manufacturing cost. Tubular members may be chamfered or tapered continuously or incrementally. Slots may be arranged in groups, such as groups of three, and may be equal in depth or unequal in depth to provide a steerable or compressible tip.Type: GrantFiled: July 31, 2007Date of Patent: September 4, 2012Assignee: Boston Scientific Scimed, Inc.Inventors: Clark C.

Publication number: 20090043228Abstract: A laser shock peening process for producing one or more compressive residual stress regions in a medical device is disclosed. A high-energy laser apparatus can be utilized to direct an intense laser beam through a confining medium and onto the target surface of a workpiece. An absorption overlay disposed on the target surface of the workpiece absorbs the laser beam, inducing a pressure shock wave that forms a compressive residual stress region deep within the workpiece. Medical devices such as stents, guidewires, catheters, and the like having one or more of these compressive residual stress regions are also disclosed.Type: ApplicationFiled: August 6, 2007Publication date: February 12, 2009Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: CLAY W.

Patent number: 5971402Abstract: Sealing assemblies are illustrated for heaters, pumps, conduits, and the like for handling process fluids used in the semiconductor-processing industry. Clean, particle-free, nonreactive, non-trapping, ultra-pure, thermally tolerant, sealed systems are required to maintain process fluids with contaminant levels below parts per billion, or even trillion. A lip seal connects a tube, having a lip at each end, to a face of a creeping material. A creeping fluorocarbon sealing material may form the interface for reducing stress concentrations on the tube, and for providing a consistent reliable seal between the lip and the creeping face. A face seal between creeping faces may be effected by a creeping sealant there between. The faces may be loaded entirely by their own creeping structural materials. No flanges are required. In certain embodiments, retaining rings may be provided for preventing unrestrained creep of sealing assemblies.Type: GrantFiled: October 31, 1997Date of Patent: October 26, 1999Assignee: Trebor International, Inc.Inventors: Clay W.
