    摘要: A catheter comprising an elongate tubular member having a proximal end, a distal end, and a passageway defining a lumen extending between the proximal and distal ends. The elongate tubular member comprises a relatively stiff proximal section and a relatively flexible distal section. The proximal section includes an inner tubular liner, a first stiffener comprising a metal alloy, and a second stiffener comprising a non-metal alloy. The first and second stiffeners are coaxially wound exterior to the proximal inner liner. The distal section includes a distal inner tubular liner and the second stiffener coaxially wound exterior to the distal inner liner. The first stiffener terminates before reaching the distal section.

    摘要: Systems and methods for treating spinal stenosis include endoscopic access devices and bone removal devices used to perform a foraminotomy or other bone removal procedures. Some of the bone removal devices include expandable members which may be used to control the forced exerted and/or position of the bone removal mechanism, and to protect neurovascular structures and other soft tissue structures from the bone removal mechanism. Other bone removal devices include a trephine with a viewing window and a guide wire lumen used to position the trephine at a target tissue site using an anchored wire. The viewing window may be used to monitor structures or tissues adjacent to the target tissue site.

    摘要: Stent and stent delivery system suited for the noninvasive treatment of aneurysms, diseased blood vessels, and other bodily lumen are described. Detachable proximal and/or distal wires connected to the proximal and distal ends, respectively, of the stent allow the operator to manipulate the position and final configuration of the stent upon deployment.

    摘要: An elongate flexible wire-like medical device, such as a guidewire for use with a catheter, is formed with a shaft in which the difference between the magnitude of the tensile yield stress and compressive yield stress of the shaft is substantially reduced. The guidewire exhibits superior kink resistance without compromising other desirable characteristics and enables a guidewire to be made in a smaller diameter without loss of performance. The guidewire shaft may be formed from a precipitation hardenable alloy such as an alloy of nickel, cobalt, molybdenum and chromium (MP35N and Elgiloy), 455PH stainless steel or stainless steel alloy 1RK91. Also disclosed is a process for increasing the modulus of elasticity of an alloy of nickel, cobalt molybdenum and chromium. Further, the disclosure relates to an improved management and manufacturing process for constructing the tip of a medical guidewire.
