Lobed balloon catheter and method of use
First Claim
Patent Images
1. A balloon catheter, comprising:
- an elongated shaft having a proximal end, a distal end, and an inflation lumen; and
a balloon on a distal shaft section having an interior in fluid communication with the inflation lumen, and having at least a section which has an uninflated configuration with at least two lobes, each with a concave inner surface and a concave outer surface, and which has an inflated configuration with a cylindrical surface;
wherein each lobe has edges in contact with edges of adjacent lobes.

Abstract
A balloon catheter with a balloon having at least a section which has an uninflated configuration with at least two lobes and an inflated configuration with a cylindrical surface. In a presently preferred embodiment, the balloon has a lobed inner surface and a lobed outer surface. In one embodiment, the balloon has a uniform wall thickness around a circumference of the lobed balloon section. However, in alternative embodiments the balloon wall thickness may nonuniform around the balloon circumference. Each lobe forms a deflated balloon wing when the balloon is deflated.

18. A method of performing a medical procedure, comprising:
-
a) positioning within a body lumen a balloon catheter, comprising i) an elongated shaft having a proximal end, a distal end, and an inflation lumen; and
ii) a balloon on a distal shaft section having an interior in fluid communication with the inflation lumen, having at least a section which has an uninflated configuration with at least two lobes each with a concave inner surface and a concave outer surface, and which has an inflated configuration with a cylindrical surface;
b) inflating the balloon from the uninflated lobed configuration to the inflated cylindrical configuration within the body lumen; and
c) deflating the balloon to the uninflated lobed configuration within the body lumen, so that each lobe forms a deflated balloon wing. - View Dependent Claims (19, 20)
