Patent number: 7276043Abstract: A catheter comprises an elongated tube having an interior defined by a sidewall having openings. At least a portion of the catheter is spirally formed into a corkscrew pattern or has an inwardly spiraling portion with at least one opening coincident therewith. Additionally or alternatively, the catheter comprises a septum that divides the interior into at least first and second lumens. The first and second lumens may form a double helix in a portion of the catheter coincident with the plurality of openings or along the entire length of the catheter. Methods of manufacturing the catheters involve extruding the portion of the catheter having the openings, making this portion separately then attaching it to another catheter, or heating and deforming a portion of a catheter to form a tip portion. The catheter can be used for hemodialysis by drawing blood through one lumen and returning it through another.Type: GrantFiled: January 29, 2002Date of Patent: October 2, 2007Assignee: SciMed Life Systems, Inc.Inventors: Kevin R.

Patent number: 6277084Abstract: Wires are used for conducting ultrasound energy. These wires achieve optimum properties by creating a multiple material coaxial construction. For example, in a particular embodiment it is desirable to have an elastic core (nitinol) for conducting axial vibrations (sonic or ultrasonic) and a thin stiff cladding (stainless steel) in order to minimize traverse vibrations which result in loss of energy.Type: GrantFiled: May 5, 1997Date of Patent: August 21, 2001Assignee: Boston Scientific CorporationInventors: John E.

Patent number: 6004279Abstract: The invention features a medical guidewire constructed for insertion into the body for providing access to a body passage. The medical guidewire has a main proximal portion in the form of an elongated tube extending the majority of the length of the guidewire, and a distal tubular portion integral with the main proximal portion. The distal portion includes a distal end and a flexible section having a slot cut in the wall of the distal tubular portion. The slot crosses the right sections of the distal tubular portion at an oblique angle and extends continuously about the distal tubular portion, in excess of at least one rotation about the distal tubular portion, to increase the flexibility of the distal tubular portion with respect to the main proximal portion.Type: GrantFiled: January 16, 1996Date of Patent: December 21, 1999Assignee: Boston Scientific CorporationInventors: Robert J. Crowley, Mark A. Hamm, Kevin R. Heath, Isaac Ostrovsky

Patent number: 5932035Abstract: A shaft is shown having inner and outer members in interfering contact along their length, at least one of which comprises a wire, at least a portion of which is superelastic, to achieve substantial mechanical fidelity and resistance to damage. An ultrasound imaging catheter has a hollow catheter shaft, an ultrasound transducer in the shaft, and a drive shaft that rotates the transducer. The shaft comprises at least one metal coil having characteristic elastic deformation under stress in the range of about 3% to 9%, while a restraint means prevents torsional deflection of the coil. A drive shaft having a coil surrounded by a tube, a coil bonded to an inner coaxial cable, and an inner and outer coil that interfere with one another are shown. A superelastic coil is formed by continuously winding a wire about a mandrel, heating a region of the wire to render it superelastic, and after cooling, removing it from the mandrel.Type: GrantFiled: January 8, 1997Date of Patent: August 3, 1999Assignee: Boston Scientific CorporationInventors: James D. Koger, Andrew Kapravv, Kevin R. Heath, Robert J. Crowley

Patent number: 5759175Abstract: An improved intra-aortic balloon catheter having an outer tube of a polymeric material and an inner tube of superelastic metal material with varying flexibility. The inner tube has a proximal end and a distal end. The inner tube is more flexible proximate the distal end than the proximal end.Type: GrantFiled: March 18, 1997Date of Patent: June 2, 1998Assignee: Boston Scientific CorporationInventors: John Ariola, Kevin R.
