A vessel and lumen expander attachment for use with an electromechanical driver device

摘要: A selectively coupleable and remotely actuateable surgical attachment for use with an electromechanical driver device in expanding occluded vessels lumens. The includes axial rod (200) which is to the device, rotatable accordance action of device. also threaded opposing orientations at either end thereof. pair nuts (210, 212) are mounted rod, specifically on threads. disposed within track permits turn, but constrains rotational motion nuts, thereby permitting move axially along threadings when turns. Attached a series jointed (232a, 232b) spokes coupled flexible tubular shroud surrounds entire assembly. radially extended retracted umbrella-like fashion actuation radial expansion provides necessary force expand vessel or lumen.
