摘要： A supportive balloon catheter which may be used to assist a wire guide in advancing across a lesion which partially or totally occludes an intraluminal passage. The supportive balloon catheter is advanced over the wire guide, close to the location of the lesion. The supportive balloon catheter is then inflated, securing the position of the wire guide in the intraluminal passage. A braid on the catheter may provide additional structural support. The secured catheter restricts the movement of the wire guide advancing across the lesion, preventing kinking or deflection off the surface of the lesion. Once the wire guide has advanced across the lesion, the supportive balloon catheter or a different angioplasty may be used to clear the lesion from the intraluminal passage.

摘要： A system for bypassing a vascular occlusion includes a catheter, and a puncturing mechanism within the catheter having a sleeve and a puncture wire positioned within the sleeve. The puncture wire is elastically deformable between an access configuration, and a deployed configuration. The puncture wire has a shape memory bias and is retracted within the sleeve and held by the sleeve in opposition to the bias in the access configuration.

摘要： An introducer set includes an introducer and dilator along with an extension in a sealed sterile peal open package. The extension is available for use during procedures where the puncture access site to the patient is close enough to the site to be treated in the patient that the physician's hands and/or head may be positioned in the fluroscopic area while the physician is attempting to maneuver a wire guide to a desired location. When the extension is attached to the introducer, the physician may perform a procedure, such as an antigrade stick in the lower leg of a patient, while maintaining their hands and head outside of the fluroscopic area while direct radiation is being supplied and the wire guide is being maneuvered to a desired treatment location. After the wire guide has been properly positioned and the radiation has been terminated, the extension may be disconnected from the introducer and the remaining portions of the procedure (guide catheter insertion, balloon catheter insertion and dilation, etc.) may proceed in a known manner. The extension need only be in the range of ten to thirty centimeters to allow the physician to work a safe distance from the fluroscopic area undergoing direct radiation.

摘要： A method of treating lower leg ischemia in a patient includes advancing a wire guide upstream through a vascular access sheath extending into an artery of the patient at a percutaneous entry point in the lower leg, and increasing a downstream flow of blood through the artery at least in part by dilating a constriction in the artery with a treatment mechanism guided into the constriction via the wire guide. A low profile balloon may be used as the treatment mechanism, and is advanced through the artery while the vascular access sheath protects the artery from irritation such that spasm of the artery is less likely to occur. Reduced risk of spasm advantageously enables retrograde access to chronic total occlusions such that multiple entry points into a patient's body are not necessary.

摘要： A lumen re-entry system includes a catheter having an elongate tubular body defining a wire lumen extending from an open proximal end of the elongate tubular body to a distal opening through the elongate tubular body. An abrasion resistant tubular liner is positioned within the wire lumen and has a fixed position relative to the elongate tubular body. The abrasion resistant tubular liner defines a reduced wire lumen extending from an open proximal end of the abrasion resistant tubular liner to an open distal end of the abrasion resistant tubular liner. A puncture wire is configured for axial movement through the reduced wire lumen and has an angled distal segment terminating in a puncture tip. The angled distal segment is oriented at an angle between about 10 degrees to about 90 degrees relative to a central longitudinal axis of the puncture wire.
