Publication number: 20230381460Abstract: The disclosure relates to medical devices and methods of assembling medical devices, such as MRI-compatible interventional wireguides. An example of a wireguide includes a series of individual segments, a plurality of connectors, and a plurality of spacers. Each segment in the series of individual segments has a first end and a second end. Each connector of the plurality of connectors joins adjacent segments in the series of individual segments to one another such that a first end of a first segment and a second end of a second segment in the series of individual segments are attached to a connector of the plurality of connectors. A spacer of the plurality of spacers is disposed between each pair of adjacent segments in the series of individual segments. Each of the segments in the series of individual segments is electrically insulated from an adjacent segment in the series of individual segments.Type: ApplicationFiled: August 14, 2023Publication date: November 30, 2023Applicant: Cook Medical Technologies LLCInventors: Ram H. Paul, JR., Richard Swift, Shuo Yang, Tracy Willis, Gary Neff

Patent number: 8177741Abstract: A retention device for use in a human or mammalian body includes superelastic wires that expand when they are released from a confined state. The retention device may have the outer form of a Foley catheter. One or more superelastic wires within the balloon of a Foley catheter help to insure retention within the body, such as within a urinary bladder.Type: GrantFiled: April 12, 2006Date of Patent: May 15, 2012Assignee: Cook Medical Technologies LLCInventors: Anthony D. Hammack, Tracy Willis

Publication number: 20070255256Abstract: An irrigation catheter having at least two lumens for supplying irrigation fluid in minimally-invasive surgical procedures is revealed. The catheter works alongside but independently of an endoscope or other diagnostic or therapeutic instrument. The catheter may direct flow of the irrigation fluid in the same direction as the body's natural flow, thus enhancing visualization by the endoscope or other instrument.Type: ApplicationFiled: March 24, 2005Publication date: November 1, 2007Applicant: Vance Products IncorporatedInventors: Frank Fischer, Thomas Foster, Tracy Willis

Publication number: 20070049907Abstract: A Foley catheter with a retention balloon includes an elongated inflation tube so that the inflation port used to inflate and deflate the balloon may be maneuvered away from the drainage port of the Foley catheter. If the Foley catheter was placed using a urethral access sheath, the elongated inflation tube allows the surgeon to easily remove the access sheath from the patient.Type: ApplicationFiled: August 11, 2006Publication date: March 1, 2007Inventors: Frank Fischer, Tracy Willis, Marvin Andrews

Publication number: 20060241665Abstract: A surgical cutter with a flat blade and a cutting wedge allows a surgeon to safely trim a foreign object inside a body, such as a urethral sling inside a patient, so that a minimum of sling remains in place after cutting. The shortened sling minimizes tension applied to the urethra and to any nearby bladder tissues. The cutter may also be used to trim other prostheses or devices implanted within a patient. The cutter is configured so that the cutting surface of the blade does not contact tissue of the patient.Type: ApplicationFiled: April 7, 2006Publication date: October 26, 2006Applicants: Vance Products Incorporated, d/b/a Cook Urological Incorporated, Sabin Corporation, a Cook Group CompanyInventors: Rodney Bosley, Tracy Willis, Geoffrey Grant
