Abstract
A cage can be positioned around a medical balloon, such as an angioplasty balloon, to assist in a medical procedure. The cage can include a plurality of strips, each extending between a set of rings including first and second rings. As the balloon expands, the first and second rings move closer together and allow the strips to expand outward. The cage may have wedge dissectors on the strips.
Claims20
A medical balloon catheter, comprising:
- an elongate member having an inner lumen, the elongate member defining a longitudinal axis;
- an expandable balloon connected to the elongate member at a distal end of the elongate member;
- a plurality of strips, each strip of the plurality of strips including a plurality of wedge dissectors spaced apart along a surface of each strip, each strip extending longitudinally along an outer surface of the balloon, wherein the wedge dissectors comprise a strip-facing base surface directly adjacent a surface of each of the strips, an unhoned radially outward facing surface having a length between a proximal edge of the radially outward facing surface and a distal edge of the radially outward facing surface and defining a height of each wedge dissector, and lateral surfaces between the strip-facing base surface and the radially outward facing surface, wherein the radially outward facing surface has a first width at the proximal edge, a second width smaller than the first width between the proximal edge and the distal edge, and a third width at the distal edge larger than the second width.
