    摘要: A catheter assembly includes a catheter shaft, a balloon and a pair of collars. The collars may be fixed or rotatable about a catheter shaft prior to exposure to an electric current. Where the collars are fixed to the shaft, the balloon is rotatable about the collars. When exposed to the electric current the collars expand to engage the waists of the balloon thereby sealing the balloon. Where the collars are rotatable about the shaft, each waist of the balloon is engaged to a respective collar. When the rotatable collars are exposed to the electric current the collars expand to engage the shaft of the catheter thereby sealing the balloon.

    摘要: Cardioprotective pacing is applied to prevent and/or reduce cardiac injury associated with myocardial infarction (MI) and revascularization procedure. Pacing pulses are generated from a pacemaker and delivered through one or more pacing electrodes incorporated onto one or more percutaneous transluminal vascular intervention (PTVI) devices during the revascularization procedure. In one embodiment, a PTVI device releases a conductive liquid to provide a conductive medium between a pacing electrode and tissue of pacing site.

    摘要: In one embodiment, an apparatus for shaping an article may comprise a plurality of movable dies arranged to form a chamber whose size may be varied by moving the dies. Each of the dies may have a contacting surface for contacting the article to be shaped. The chamber may have a first portion having a first cross-section and a second portion having a second cross-section. Either portion may include a taper. The first portion may have a differently shaped cross-section than the second portion. The first portion may have a cross-section of greater area than the second portion. The longitudinal axis of the first portion may be offset from the longitudinal axis of the second portion.

    摘要: A catheter assembly comprises a catheter shaft, a balloon and a pair of collars engaged to the catheter shaft. Each collar has a body portion and at least one lip portion extending radially outward from the body portion. Each collar has a nonactivated state and an activated state, wherein in the nonactivated state the balloon is rotatable about the collars and each lip portion is constructed and arranged to abut a portion of the balloon to prevent the balloon from moving longitudinally relative thereto. In the activated state the body portion of each collar is sealingly engaged to at least a portion of the balloon.

    摘要: Systems for treating a vessel bifurcation comprise a bifurcated catheter having a first branch and a second branch. Each branch defining an exchange region that extends from the distal end of the shaft to the guidewire port of the shaft. The catheter has a radial alignment mechanism which provides improved radial alignment characteristics of at least the exchange region of the branches.
