摘要： A balloon dilatation catheter having a catheter shaft with an oblong transverse cross-section with one transverse dimension in a first direction being significantly larger than a second transverse dimension in a direction perpendicular to the first direction. The first dimension is about 1.1 to about 3 times greater, preferably about 1.2 to about 2.5 times greater than the second dimension. In one embodiment, a length of the distal shaft section has inner and outer tubular members where about 30% to not more than about 90% of the inner periphery of the outer tubular member takes the shape of and is secured to the exterior of the inner tubular member. In another embodiment the flexible distal shaft section is an extruded section having an oval or elliptical transverse cross-section. Preferably a pseudoelastic hypotube of NiTi alloy defines at least part of the inflation lumen within the catheter shaft. In another embodiment of the invention the proximal shaft of the catheter has an inner and outer tubular member.

摘要： An intravascular imaging guidewire is provided that can accomplish longitudinal translation of an imaging plane allowing imaging of an axial length of a region of interest without moving the guidewire. The imaging guidewire comprises a body in the form of a flexible elongate tubular member. An elongate flexible imaging core is slidably received within the body. The imaging core includes a shaft having an imaging device mounted on its distal end. The body and the imaging core are cooperatively constructed to enable axial translation of the imaging core and imaging device relative to the body. The body has a substantially transparent portion extending an axial length over which axially translatable imaging may be performed. The imaging guidewire has a maximum diameter over its entire length sized to be received within a guidewire lumen of an intravascular catheter.

摘要： A perfusion dilatation catheter is disclosed which has an improved distal catheter shaft portion with a tubular member extending within the balloon provided with an expanded coil support incorporated within the wall of the tubular member. The coil is preferably closer to the inner surface than the outer surface of the tubular member. Also disclosed are improved catheter shaft sections in a perfusion portion proximal to the balloon, one with a reinforced inflation tube depending into the guidewire lumen and another having three separate lumens, a central guidewire lumen and a pair of inflation lumens on opposing sides of the tubular structure defining the guidewire lumen.

摘要： An embolic protection filtering device and methods and making and using filtering devices. An example filtering device may include an elongate shaft or filter wire, a filter coupled to the filter wire, and a sheath. The methods for using the filtering device include using an introducer member to help back load a guidewire into the sheath and then advance the filtering device along the guidewire to a target region.
