Abstract
Catheter devices for treating occlusions in body lumen are described herein. The catheter devices may include a tubular body having a distal end, an distal portion elastically connected to the distal end of the tubular body, an impactor connected to the distal portion and separated by a space from the distal end of the tubular body, a distal shock wave emitter located adjacent to the space and connected to a power source, and an enclosure at least partially surrounding each of the distal end of the tubular body, the elastic distal portion, the impactor, and the distal shock wave emitter. The impactor may be configured to move in response to shock waves generated from the distal shock wave emitter, such that a length of the space in the proximal-distal direction increases by between 0.05 mm and 0.6 mm.
