Publication number: 20220387058Abstract: The present specification is directed towards catheter devices having expandable and collapsible lumens. Air or fluid is pumped into the catheter wall to cause it to expand. Alternatively, wires are embedded within the wall and a direction of flow of electrical current through the wires is modulated to enable the catheter device to be in the collapsed or expanded state. For example, a first wire is embedded within the wall and is helically wound along a length of the catheter device. A second wire is provided that can be removably positioned within the lumen. The direction of flow of electric current through the first and second wires is modulated to enable the catheter device to be in the collapsed or expanded state.Type: ApplicationFiled: June 28, 2022Publication date: December 8, 2022Inventors: Michael Bruce Horowitz, Benjamin William Bobo, Brandon Matthew Repko, Hieu Le
