Multipart split sleeve balloon protector for dilatation catheter
First Claim
Patent Images
1. A balloon protector for a balloon catheter having a balloon positioned adjacent a distal end, the balloon protector comprising:
- an inner sleeve having an interior for receiving the balloon; and
an outer sleeve having an interior for receiving the inner sleeve, the interior of the outer sleeve being sized smaller than an exterior of the inner sleeve, such that the outer sleeve applies a radially inward compressive force to the inner sleeve and the balloon when the outer sleeve is applied over the inner sleeve.
