Abstract
Abstract Dilatation catheters for use in administering treatments to relieve stenotic regions within a body lumen are described. In one aspect of the invention, a two wire catheter system, of minimal diameter for treating distal arteries is disclosed. In addition, a number of various dilatation balloon configurations, for treating stenotic areas which are present in tortuous vessels, as well as hardened, or calcified stenotic portions are also described. Finally, a catheter system which provides a path for conducting blood past the stenosis and inflated dilatation balloon is discussed.

Claim 1
Independent Claim
94 words
A dilation catheter for negotiating and dilating tortuous vessels within the body, comprising: an axially elongate catheter shaft, suitable for insertion into a body lumen; and a multi-lobed dilatation balloon, secured to said catheter shaft, said multi-lobed dilatation balloon being comprised of alternating regions of thick and thin balloon material, wherein said thin portions readily expandable when connected to a source of pressurized fluid so as to radially expand said body lumen, and wherein said thick portions are resistant to expansion, so as to more readily conform to the contours of the body lumen.
