Abstract
A treatment device includes a housing having a longitudinal axis extending between a proximal end and a distal end, a motor, a drive shaft operatively coupled to the motor, a compression spring at least partially disposed about the drive shaft, a helical cam disposed adjacent the compression spring, the helical cam having at least one discontinuity, a hammer coupled to the helical cam and moveable therewith, and a tip disposed adjacent the distal end.
Claims18
A method of treatment, comprising:
- providing a treatment device including a housing having a longitudinal axis extending between a first end and a second end, a motor disposed within the housing, a drive shaft operatively coupled to the motor, a compression spring at least partially disposed about the drive shaft, a helical cam disposed adjacent the compression spring, the helical cam having a first flat end, and a second end having at least one discontinuity, wherein the drive shaft passes through the first and second ends of the helical cam and includes at least one cam follower configured to travel along the helical cam, a hammer coupled to one of the helical cam and the drive shaft and moveable therewith, and a tip;
- and
- striking the tip with the hammer at repeated intervals to create a shock wave.
