    摘要： Disclosed is a focal balloon having at least one reference zone and a focal zone. In one embodiment, the reference zone and focal zone are inflatable to a first generally cylindrical profile at a first pressure. At a second, greater pressure, the focal section expands to a second, greater diameter, while the reference zone remains substantially at the first diameter. In an alternate embodiment, the focal zone and the reference zone are inflatable to their respective predetermined diameters at the inflation pressure, in the absence of constricting lesions or anatomical structures. Multiple lobed and drug delivery embodiments are also disclosed.

    摘要： Systems and methods for delivering implantable devices, catheters, or substances in or near and/or restoring flow through body lumens, such as blood vessel lumens are described. A catheter having a proximal portion of a first diameter and a distal portion of a second diameter (smaller than the first diameter) is advanced into a body lumen. The distal portion of the catheter is caused to expand to a diameter that is larger than the second diameter but no larger than the first diameter. A working device is then advanced out of the distal end of the catheter and used to remove obstructive matter, deliver an implantable device or substance and/or restore flow. The distal portion can be reduced in diameter prior to removal from the body. A stand alone, guide catheter is also disclosed possessing high resistance to kinking even with a very thin wall.

    摘要： Disclosed is a tuvular sheath which is adapted to fit coaxially over an inflatable balloon. The sheath functions to alter the expansion characteristics of the balloon. In one preferred embodiment, the sheath converts the inflation profile of a dilatation balloon from a compliant mode to a noncompliant mode. Advantageously, the balloon sheath may be used in stent placement procedures, to accurately size the stent within a body lumen, while providing protection against balloon rupture. In one embodiment, the balloon sheath comprises a two-layered tubular structure, with an outer elastic layer surrounding an inner inelastic layer. Also disclosed are methods of altering the expansion characteristics of a balloon using the balloon sheath.
