Abstract
Abstract A catheter comprising a tubular structure having a channel extending through it. A connector is attached to one end of the structure, and adapted to be connected to an energy source. Energy guide fibers extend through the connector and are embedded in the tubular structure, and are adapted to be connected to the energy source. The connector has at least one inlet port connected to the channel. A shaped memory alloy is woven with certain portions of the energy guide fibers on one side of the tubular structure.
