Patent number: 6355005Abstract: Disclosed herein is an articulated guidewire for insertion into a blood vessel. The articulated guidewire includes a rotatable sensor cable, a sensor, a connector, and a satellite wire. The sensor cable has a proximal end and a distal end. A sensor connects to the sensor cable near the distal end and rotates with the sensor cable. The satellite wire attaches to the distal end of the sensor cable and holds the sensor cable in the blood vessel. The connector includes a ball and socket joint which aligns the satellite wire and the sensor cable at a variable angle.Type: GrantFiled: March 9, 1998Date of Patent: March 12, 2002Assignee: Devices for Vascular Intervention, Inc.Inventors: Ferolyn T. Powell, Larry Rogers, Ron Ray Hundertmark, Charles Milo

Patent number: 6120515Abstract: An athetectomy catheter is disclosed having a composite cutter which is capable of cutting material, including hardened plaque, from a biological conduit. The composite cutter has a cutter and a sensor mount. The cutter has a proximal end and a distal end with a cutting edge. The proximal end of the cutter bonds with the sensor mount. The sensor mount is adaptable for holding a sensor and attaching to a cutter torque cable of an atherectomy catheter. Typically, the atherectomy catheter has a cutter housing with a window. The composite cutter is positioned in the cutter housing and moves in response to movement of the cutter torque cable to cut material from the biological conduit via the window.Type: GrantFiled: July 16, 1997Date of Patent: September 19, 2000Assignee: Devices for Vascular Intervention, Inc.Inventors: Larry Rogers, John Thomas Buckley, Ron Ray Hundertmark, Ferolyn T. Powell, Charles Milo, Anthony J. Castro

Patent number: 5895402Abstract: Intravascular catheters that include a flexible catheter body, a distal housing secured to the catheter body, a work element disposed within the housing and exposed to the external environment through a side window, and a guiding structure for the work element, are disclosed. An axial path through the housing is defined by the guiding structure. Embodiments of the guiding structure include a slot or channel formed in the housing, a coaxial tube attached to the housing, a radially offset ribbon attached to the housing, or the external surface of the housing itself. The work element, such as a rotatable cutting blade in an atherectomy catheter, is coupled to the guiding structure such that the work element is retained within the housing during insertion and operation of the catheter and even when the housing is bent or distorted as a result of bends in the blood vessel.Type: GrantFiled: January 17, 1997Date of Patent: April 20, 1999Inventors: Ron Ray Hundertmark, Brian Farley, Kent D. Dell, Bernard H. Andreas

Patent number: 5868767Abstract: Disclosed herein is an intravascular universal catheter having interchangeable work elements and methods of use thereof. The catheter comprises a flexible catheter body having a distal end, a proximal end and a lumen extending between the ends. A housing having an open interior and an aperture on a lateral side is attached to the distal end of the catheter body by a coupling element. A work element is movably disposed within the housing and operative through the aperture. A work element connector is disposed in a lumen of the catheter body and has a distal end connected to the work element. At least the distal portion of the lumen defines a receiving space within the catheter body, and the coupling element is configured to allow retraction of the work element from the housing through the open proximal end into the receiving space. In a preferred embodiment, perfusion ports are disposed in the catheter body and the housing proximate to the junctional region of the catheter body with the housing.Type: GrantFiled: January 17, 1997Date of Patent: February 9, 1999Assignee: Devices For Vascular InterventionInventors: Brian Farley, Ron Ray Hundertmark, Grace Yen Schulz
