Abstract
A catheter device for use in a biological conduit includes a catheter body having a proximal end and a distal end, a housing connected to the distal end of the catheter body, the housing including a window for invaginating biological tissue and a work element movably attached to operate within the housing, the window exposing the work element. A cage member is attached to the housing and partially covers the window, the cage member permitting a selective invagination of biological tissue therethrough into the window. When the catheter device is inserted in the biological conduit, the cage member selectively controls an invagination of tissue within the catheter device while preventing invagination of any stent material or invagination of walls of the biological conduit.
