Abstract
A medical device may include an inflatable balloon secured to a distal region of a catheter shaft. A blade assembly may extend over and be secured to the inflatable balloon. The blade assembly may include a plurality of blades and at least two rings that are adapted to secure each of the plurality of blades. Each of the rings include an inner surface adapted to be secured to the inflatable balloon and an outer surface. A number of living hinges are formed within the inner surface and the outer surface that cooperate to allow the blade assembly to move between an expanded configuration and a collapsed configuration.
Claims20
A medical device, comprising:
- a catheter shaft including a distal region;
- an inflatable balloon secured to the distal region of the catheter shaft, the inflatable balloon including an outer surface;
- and
- a blade assembly extending over and secured to at least part of the outer surface, the blade assembly comprising:
- a plurality of blades;
- at least two rings adapted to secure each of the plurality of blades, each of the at least two rings moveable between an expanded configuration in which each of the at least two rings have an annular profile and a collapsed configuration in which each of the at least two rings collapse radially inwardly, each of the at least two rings including:
- an inner surface adapted to be secured relative to the outer surface of the inflatable balloon;
- an outer surface opposite the inner surface;
- a plurality of living hinges formed within the inner surface;
- and
- a plurality of living hinges formed within the outer surface;
- and
- wherein the plurality of living hinges formed within the inner surface and the plurality of living hinges formed within the outer surface cooperate to allow each of the plurality of blades to move radially inwardly in the collapsed configuration.
