    摘要： A guide catheter employs a flexible shaft having a pre-formed bend at a distal end. An inflatable member is disposed on the flexible shaft and encompasses at least part of the pre-formed bend. The flexible shaft contains an inflation lumen in fluid connection with the inflatable member. Inflation of the inflatable member causes a deflection of the distal end of the flexible shaft. The guide catheter includes an inflation mechanism in fluid connection with the inflation lumen for pressurizing and depressurizing the inflation member. A guide catheter according to the present invention is useful for various medical procedures, including providing access to heart vessels for cardiac lead implantation, EP mapping, and angiography/venography.

    摘要： A peel-away sheath for a catheter includes at least one weakened area in a non-longitudinal pattern, such as a helical pattern, along the length of the sheath. One embodiment of a catheter sheath includes a tube having at least one pull wire integrally located within its wall. Another embodiment of a catheter sheath includes a tube having at least one integral lumen within its wall. The integral lumen may house a filling material. One embodiment of a catheter may include a first sheath which is positioned within a second sheath, with each of the first and second sheaths having at least one weakened area along its length. A reinforcing guide for a guide catheter includes a tube having a lumen with a diameter at least as large as the guide catheter diameter. The reinforcing guide includes a gap with a width which is less than the guide catheter diameter.

    摘要： A method for placing a device into a target vasculature. The method comprises accessing the target vasculature with an access guide catheter to sub-select a proximal portion of the target vasculature. A rail catheter is tracked into the access guide catheter to place the rail catheter more distally and into a distal portion of the target vasculature. The access guide catheter is removed. A delivery catheter is tracked over the rail catheter. The rail catheter is then removed. A device catheter having the device is placed into the delivery catheter and positioned at a desired location within the distal portion of the target vasculature.

    摘要： A hemostasis seal configured for use in a splittable hemostasis valve, hub, or introducer sheath to permit passage of a medical device therethrough. The seal provides a substantially fluid-tight seal around the medical device without causing excessive frictional resistance that would otherwise unduly restrict movement of the medical device through the seal. In one embodiment, the seal includes first and second resilient seal portions each having a contoured mating surface to provide a first fluid seal with respect to the medical device. The seal also may include one or more projecting portions and one or more mating receiving portions which interact to provide a second fluid seal with respect to the medical device.

    摘要： A device and method for removing a guide catheter from about a cardiac lead is disclosed. The device includes a blade for slitting the catheter so that the catheter may be removed from the lead. The blade includes upper and lower angled cutting surfaces which define a notch. The device includes a portion for receiving the lead and guiding the catheter to the blade.
