Abstract
The invention provides a non-occlusive dilation and deployment catheter device which includes a catheter having a distal end configured for entering a patient and a proximal end for manipulating the device. A distender is provided at or near the distal end which is movable between a collapsed configuration which enables introduction and removal thereof to and from an operative site in a vessel or other hollow organ of a patient, and an expanded configuration in which the distender assumes a radially expanded condition and defines a flow path therethrough. The distender includes a substantially tubular, radially expandable frame having a plurality of spaced apertures and at least one inflatable tube threaded through the apertures and shaped to extend in a spiral when inflated. The distender is movable to the expanded configuration by inflating the tube, and movable to the collapsed configuration from the expanded configuration by deflating the tube.
