Abstract
Devices and methods are described for penetrating hard plaque that partially or completely occludes blood vessels and disturbs blood flow through the blood vessel. The device includes a distal pre-loaded spring that can store energy and release it as impact at the device distal tip, in order to penetrate or break through hard plaque that is blocking blood path in blood vessels.
Claims10
A crossing device comprising:
- a shaft having a distal portion and a proximal portion;
- a handle with an activating mechanism attached to said proximal shaft portion;
- and
- an impactor fixedly connected to a tube and positioned at said distal portion, said impactor being biased by a distal biasing device which abuts against a proximal face of said impactor, and said tube being arranged to slide inside said distal portion, wherein said tube is coupled to said activating mechanism, said distal biasing device operative to store energy and release energy as an impact force through said impactor sufficient to penetrate or break through hard plaque in blood vessels;
- and wherein fixed connection of said impactor to said tube is independent of any connection of said impactor or said tube with respect to said shaft and wherein said distal biasing device is external to said impactor, and wherein said tube is coupled to said activating mechanism with a cord and said cord is attached to a rotating member arranged to rotate around a pivot.
