Narrow profile composition-releasing expandable medical balloon catheter

The present invention relates to a composition-eluting balloon catheter ( 100 ) having a proximal ( 20 ) and distal ( 15 ) end, comprising an elongated catheter tube ( 6 ) with an inflation lumen ( 7 ) extending therewithin and at least one inflatable balloon ( 4 ) towards the distal end ( 15 ) in fluid communication with the inflation lumen ( 7 ), wherein the balloon ( 4 ) in the uninflated condition is provided as one or a plurality of folded wings ( 10′, 10 ″), and composition ( 12′, 12 ″) is provided essentially exclusively within the folds of the wings ( 10′, 10 ″), wherein the balloon ( 4 ) in the uninflated condition is further provided with a relief structure ( 30 ) comprising at least one groove on the outside of the folded wings ( 10′, 10 ″), configured to substantially reduce in depth in an inflated state of the balloon ( 4 ), and whereby the at least one groove is essentially devoid of composition ( 12′, 12 ″).

NARROW PROFILE COMPOSITION-RELEASING EXPANDABLE MEDICAL BALLOON CATHETER

A process for making a folded composition-eluting balloon catheter includes coating one or both surfaces of a one or more foldable wings with a hydrophilic coating, applying a composition as a coating on the coated surface and providing the composition within a fold of the one or more foldable wings, and folding the one or more foldable wings to seal the composition by the one or more foldable wings to prevent/reduce its release until after inflation of the balloon. Another process for making a folded composition-eluting balloon catheter includes coating one or both surfaces of the one or more foldable wings with a hydrophilic coating-composition mixture and providing the composition by the one or more foldable wings, and folding the one or more foldable wings to seal the composition between the fold of the one or more foldable wings to prevent/reduce its release until after an inflation of the balloon. 1. A process for making a folded composition-eluting balloon catheter having a proximal end and a distal end , comprising an elongated catheter tube with an inflation lumen extending therewithin and at least one inflatable balloon having a central longitudinal balloon axis towards the distal end in fluid communication with the inflation lumen , wherein the balloon in an uninflated condition is configured as one or more foldable wings , wherein the balloon in a folded condition comprises a relief structure comprising at least one groove on the outside of the one or more foldable wings , configured to substantially reduce in depth in an inflated condition of the balloon , wherein the at least one groove crosses an outer edge of at least one of the one or more foldable wings , the process comprising the steps of:a) coating one or both surfaces of the one or more foldable wings with a hydrophilic coating such that one or both surfaces of the one or more foldable wings are provided with a coated surface;b) applying a composition as a coating on the coated surface from ...
