Swaging machine and method of use
First Claim
1. A swaging machine configured to swage a marker band onto a catheter, comprising:
- a feed system comprising a motor and a clamp, the clamp slideably disposed on a rail, the motor in driving engagement with the clamp and configured for transmitting a feeding force to the clamp, the motor being operatively coupled to a feed screw, the feed screw having a coupled end connected to the clamp, the motor configured to drive the feed screw and the clamp linearly, the feed system further comprising a damping coupling between the feed screw and the clamp;
an impact system comprising a hammer and a die, the hammer configured to deliver an impact to the die, the die configured to distribute the impact force as a swaging force to the marker band; and
a rotation system comprising a motor and configured to rotate the impact system to distribute the swaging force about a circumference of the marker band.

Abstract
A swaging machine is configured to substantially uniformly reduce the diameter of a tubular attachment, such as a marker band, to result in a smooth and repeatable finished part. The swaging machine comprises a feed system, an impact system, and a rotation system. A split die having a compound die cavity is provided for use in conjunction with the swaging machine to receive an impact force from the impact system and, in turn, apply a swaging force to the marker band. The rotation system rotates the impact system, including the die, about the axis of the marker band to apply swaging forces about the circumference of the marker band, while the feed system feeds the marker band through the die thereby applying swaging forces along the length of the marker band.
