COMFORMABLE BALLOON DEVICES AND METHODS

摘要

The present disclosure is directed toward a semi-compliant to non-compliant, conformable balloon useful in medical applications. Conformable balloons of the present disclosure exhibit a low or insignificant straightening force when in a curved configuration and at inflation pressures greater than 4 atm. Balloons of the present disclosure are constructed of material that can compress along an inner length when the balloon is in a curved configuration. In further embodiments, balloons of the present disclosure can be constructed of material that sufficiently elongates along an outer arc when the balloon is in a curved configuration. As a result, medical balloons, in accordance with the present disclosure, when inflated in a curved configuration, exhibit kink-free configurations and do not cause a significant degree of vessel straightening.

主权项

1. A medical balloon having a working length and comprising
a balloon wall defining a chamber, wherein the balloon wall is configured such that, when the medical balloon is inflated by an inflation fluid in a curved configuration having a neutral axis requiring 20% total strain, the medical balloon, along a portion of the working length, defines a curved configuration including an inner arc, a center axis, an outer arc where a portion of balloon wall extending along the inner arc undergoes at least 5% compressive strain, wherein the medical balloon is semi-compliant to non-compliant, wherein the balloon wall is configured to remain kink-free when inflated in the curved configuration, wherein the center axis of the balloon and the neutral axis of the curved configuration are co-radial, and wherein the balloon wall is capable of perfusion.
