Publication number: 20110196260Abstract: A catheter assembly is provided with a flexible tubular body having two lumens. A solid slidable member with a sharp distal end is disposed within one of the lumens. The slidable member is capable of sliding within the lumen of the tubular body between an exposed position in which the sharp distal end of the slidable member protrudes from the distal end of the tubular body and a shielded position in which the distal end of the slidable member is within the tubular body. One advantage is that the sharp distal end of the slidable member may be withdrawn into the tubular body in order to shield a patient from unintentional cutting or irritation from the sharp distal end of the slidable member.Type: ApplicationFiled: January 25, 2011Publication date: August 11, 2011Applicant: Cook IncorporatedInventors: Jeffry S.

Publication number: 20110000484Abstract: System and methods for applying vascular therapy to a body vessel using a chamber capable of negative and/or positive pressure relative to ambient are provided. The chamber includes one or more pressure-isolated chambers. A pressure and/or vacuum source is connected to the pressure chamber, and is configured to provide distinct pressures within each pressure-isolated chamber. A controller is coupled to the pressure source, and is configured to control the pressure source such that pressure within each of the pressure-isolated chambers is controlled cyclically to simulate a pulsating pump or peristaltic-like pump action within the body vessel. The use of negative pressure is sequenced such that the resistance to pressure toward the heart is reduced. This effectively “pulls” blood flow toward the heart and creates more space for incoming blood flow. During simulation, medical devices may be introduced to and/or diagnostics may be performed on the targeted vessel.Type: ApplicationFiled: July 2, 2009Publication date: January 6, 2011Applicant: Cook IncorporatedInventor: Jeffry S.

Publication number: 20100318068Abstract: A coupling wire guide structured to be slidably coupled to a previously introduced wire guide. The coupling wire guide generally includes a main body having a distal end and a coupling tip connection to the distal end. The coupling tip includes a coupling portion defining a coupling passageway having a proximal port and a distal port. A slot is formed in the coupling tip and is in communication with the coupling passageway. The slot extends from the proximal port to the distal port, thereby permitting the coupling wire guide to be “clipped-on” to the mid-section of the previously introduced wire guide or any location having the most efficacy.Type: ApplicationFiled: August 18, 2010Publication date: December 16, 2010Applicant: COOK INCORPORATEDInventor: Jeffry S.

Patent number: 7762985Abstract: The present invention provides apparatus and methods for treating vascular conditions, and in particular, hardened or fibrous material in a stenosis. In a first embodiment, the apparatus comprises a catheter having proximal and distal regions and a plurality of balloons segments disposed on the distal region at intervals about a circumference of the catheter. A first set of opposing balloon segments are configured to be inflated at substantially the same time to apply a first pressure on the vascular condition, and then a second set of opposing balloon segments are configured to be inflated at substantially the same time to apply a second pressure on the vascular condition. The plurality of balloon segments may be formed by taking one length of balloon material and affixing the material to an outer surface of the catheter at a plurality of segment dividing locations to separate adjacent balloon segments, or alternatively, by providing multiple separate balloon materials.Type: GrantFiled: October 26, 2007Date of Patent: July 27, 2010Assignee: Cook IncorporatedInventors: Chris R.
