Embodiment Construction

[0029] The invention provides a textured dilation balloon, a method of making and a method of using it. In one embodiment, the textured inflatable balloon comprises a balloon body having a proximal end, a distal end and at least one indentation in the balloon body in an uninflated state, wherein the balloon body comprises a continuous polymeric tube, The outer surface of the tube has at least one therapeutic agent disposed within the at least one indentation prior to use.

[0030] In certain embodiments, the textured inflatable balloon includes a plurality of indentations (ie, depressions, cavities, or pits), such as a plurality of dimples, when in an uninflated state. Alternatively, the bladder body may comprise a continuous indentation, for example in the form of a continuous channel or groove when in the uninflated state. Controlling the shape, size, and / or volume of the one or more indentations, as well as the number and location of the indentations, facilitates controlli...

Abstract

The present disclosure provides a textured dilatation balloon that includes a balloon body having a proximal end, a distal end, and at least one indentation (20) in the balloon body in an un-inflated state, wherein the balloon body comprises a continuous polymer tube with an external surface having at least one therapeutic agent disposed within the at least one indentation.

Description

Background technique [0001] Surgical procedures using balloons and medical devices containing such balloons (ie, balloon catheters) are becoming more common and routine. These procedures, such as angioplasty, are performed when it is necessary to dilate or open a narrow or blocked opening in a blood vessel or other passageway in the body to increase flow through the blocked area. For example, in the procedure of angioplasty, a dilation balloon catheter is used to enlarge or open a blocked blood vessel that is partially restricted or blocked due to the presence of a hard stenosis or formation within the vessel. The procedure entails inserting a balloon catheter into the patient and positioning it within the blood vessel so that when the balloon is inflated, the balloon will expand the blocked or narrowed area to minimize the blockage or narrowing, thereby causing blood flow through the vessel. flow increases. [0002] Once the balloon has been placed at the stenosis, it is re...
