  • Patent number: 9731094
    Abstract: An introducer sheath for deploying a stent to a target site within a body passageway of a patient. The introducer sheath includes a tubular inner liner having a proximal portion, a distal portion, and an outer surface. A first reinforcing element, and a second reinforcing element are positioned along the outer surface of the inner liner. The first reinforcing element comprises a braid the second reinforcing element comprises a coil. The braid is positioned at the proximal portion of the inner liner and extends distally therefrom. The coil is positioned at the distal portion longitudinally adjacent the braid. The braid has a length that may extend about 90% of the length of the sheath. An outer jacket is positioned longitudinally around the reinforcing elements, and is connected to the inner liner between the respective wires of the braid and the coil.

  • Patent number: 9346181
    Abstract: A cutting tool is provided for cutting the end of a catheter to provide custom length catheters. The cutting tool has a cutting member that moves within the cutting passageway in the housing. The catheter is positioned within a catheter passageway in the housing. The cutting passageway transacts the catheter passageway so that a blade on the cutting member crosses the catheter passageway and cuts through the width of the catheter to form a cut end on the catheter.
