摘要： An over-the-wire balloon dilatation catheter of the short guide wire lumen type has a stainless steel hypotube catheter shaft section, a distal plastic shaft section attached to the hypotube and a balloon connected to the distal plastic shaft section. A relatively short guide wire lumen extends throughout the length of the balloon. The distal shaft section includes a reinforcing and kink-resistant transition member extending throughout the length of the distal shaft section. The transition member allows the proximal guide wire lumen aperture to be placed distally from the distal end of the hypotube. This configuration permits the length of the guide wire lumen to be minimized.

摘要： An embolic protection system and method of treating occluded vessels which reduces the risk of distal embolization during vascular interventions is provided. The embolic protection system includes a guide catheter, a multi-lumen tube having a sealing surface on the distal end and an interventional device. A method of treating a blood vessel includes providing a guide catheter and a multi-lumen elongate member having proximal and distal ends, evacuation and inflation lumens extending therebetween and a sealing surface on the distal end. The elongate member is advanced through the guide catheter into a blood vessel that supplies blood to the heart proximal a lesion. The sealing surface is expanded to engage the endoluminal surface of the blood vessel and stop antegrade flow. An interventional device is advanced through the evacuation lumen to treat the lesion.

摘要： A method for treating a natural drainage passageway in a subject includes forming a cannulated artificial passageway into a subject's sinus cavity through the canine fossa region with a piercing member, the piercing member containing a hollow cannula thereon, the cannula comprising an elongate flexible member having a lumen passing therethrough. The piercing member is removed so as to leave the cannula in place. A balloon dilation catheter is then advanced within the lumen of the cannula so as to place the dilation balloon at least partially across the natural drainage passage in the sinus cavity. The dilation balloon is dilated so as to at least partially expand the natural drainage passageway.

摘要： An evacuation sheath assembly and method of treating occluded vessels which reduces the risk of distal embolization during vascular interventions is provided. The evacuation sheath assembly includes an elongated tube defining an evacuation lumen having proximal and distal ends. A proximal sealing surface is provided on a proximal portion of the tube and is configured to form a seal with a lumen of a guided catheter. A distal sealing surface is provided on a distal portion of the tube and is configured to form a seal with a blood vessel. A method of treatment of a blood vessel using the evacuation sheath assembly includes advancing the evacuation sheath assembly into the blood vessel through a guide catheter. Prior to advancing a device across a stenosis to be treated, normal antegrade blood flow in the blood vessel proximate to the stenosis is stopped. While blood flow is stopped, the stenosis is treated. Retrograde blood flow is induced within the blood vessel to carry embolic material dislodged during treating into the evacuation sheath assembly.

摘要： An endovascular graft system used to repair aneurysms in arteries which bifurcate such as the aorta which bifurcates at the aortoiliac junction. The graft system includes two legs, each defining a lumen. Each leg comprises an aortic stent, a graft component and an iliac stent. The graft component is affixed at one end to the aortic stent and at the other end to the iliac stent. Each leg of the graft system is preferably a mirror image of the other with the exception of the aortic stents. The graft component of each leg includes a means for allowing in situ adjustment of the length of the leg to accommodate the different sizes required for different patients.

摘要： According to the invention, a novelly improved ablation device includes releasably joinable drive and catheter assemblies. The drive assembly includes a tachometer assembly and a regulator for monitoring and controlling ablating burr speed. A bifurcated drive shaft includes a coiled distal portion and a tubular proximal portion for facilitating force transfer from the proximal portion to the distal portion. A dilating member is provided in addition to an ablating burr on the catheter assembly. The catheter tube may have multiple independent lumens having axes of elongation offset parallelly in the tube. Additionally, the ablating burr may be operatively connected to the catheter tube by drive gears or releasable threads. A radiopaque member is included on the distal end of the catheter tube, thereby rendering it visible to an observer. Novel, improved methods of ablating intravascular deposits are also provided.
