Medical balloon

摘要

A non-compliant medical balloon, where the non-compliant medical balloon may be changed from a deflated state to an inflated state by increasing pressure within the balloon, is made with a first fiber layer, a second fiber layer over said first fiber layer such that the fibers of the first fiber layer and the fibers of the second fiber layer form an angle and a binding layer coating the first fiber layer and said second fiber layer. The interior surface area of the non-compliant medical balloon remains unchanged when the balloon changes from a deflated state to an inflated state.

主权项

1. A non-compliant medical balloon, comprising:
a surface defining a cylindrical shape with a circumference and a long axis when in an inflated or deflated state; a plurality of first inelastic fibers attached to an exterior of the surface, said plurality of first fibers being substantially equal in length to a length of the long axis and extending substantially parallel to the length of the long axis; at least a second inelastic fiber attached to the plurality of first fibers, said at least one second fiber extending radially around the circumference and substantially over the length of the long axis; and a polymeric solution applied to the plurality of first fibers and the at least one second fiber together defining an outer surface such that the surface substantially maintains the cylindrical shape during subsequent deflation and inflation of the balloon.
