Balloon catheter for hyperthermia treatment

Apparatus for medical treatment

A device for transluminal extraction or implantation of a substantially tubular, radially expansible stent. The device includes a central tube surrounded by an exterior tube axially displaceable relative to the central tube and a plurality of axially extending gripping members coupled to the central tube at a distal end thereof. The gripping members are substantially evenly distributed around the periphery of the central tube and capable of outward expanding action of their distal ends when the central tube is displaced relative to the exterior tube. The gripping members are arranged in at least two concentric sets with a first set being radially displaced relative to a second set so as to substantially cover the gaps between adjacent gripping members of the first and second sets when in an expanded position. The sets of gripping members form a substantially closed distal end periphery when in the expanded position permitting a substantially continuous circumferential engagement around the stent.
