Abstract
A balloon angioplasty or stenting apparatus includes a guide wire, a balloon catheter ensleeving the guide wire, and a guide catheter ensleeving the balloon catheter. The balloon catheter has slots formed in it to define elongate members between the slots. A joint is formed at the proximal, distal, and mid-point of each elongate member. Displacing the proximal and distal joints toward and away from one another causes the respective middle joints to displace radially outwardly and inwardly, respectively. A mesh that captures emboli while allowing blood perfusion partially overlies the jointed members is opened and closed when the jointed members are opened and closed. A guide wire having an outer coil and an inner rod slideably received within it has jointed members formed in the outer coil. The mesh is opened and closed by axially retracting and advancing the inner rod with respect to the outer coil, respectively.
