Abstract
The present invention is directed to a polymeric balloon for an intracorporeal catheter having a plurality of spaced apart, remotely imageable layers which facilitate the folding of the balloon. The imageable layer may facilitate imaging the balloon or a portion thereof preferably by fluoroscopic or magnetic resonance based remote imaging systems.
Claims16
A polymeric balloon having a wall with an interior surface defining at least in part an internal chamber and a plurality of longitudinally oriented, coextensive and spaced apart layers of remotely imageable materials on the interior balloon surface or within a portion of the balloon wall which are configured to facilitate articulation between adjacent spaced apart layers and preferential longitudinal folding of the balloon.
A balloon catheter assembly for stent delivery comprising
- a) a catheter shaft having at least one lumen;
- b) a polymeric balloon which is disposed about and secured to a distal portion of the catheter shaft, which has a wall with an interior surface defining at least in part an internal chamber and which has a plurality of longitudinally oriented, coextensive and spaced apart layers of remotely imageable materials on the interior balloon surface or within a portion of the balloon wall which are configured to facilitate articulation between adjacent spaced apart layers and preferential longitudinal folding of the balloon;
- and
- c) a stent having a proximal end and a distal end disposed about the balloon.
A balloon catheter comprising
- a) a catheter shaft having at least one lumen;
- and
- b) a polymeric balloon which is disposed about and secured to a distal portion of the catheter shaft and which includes a working section having at least two adjacent wall segments with each segment having longitudinally oriented, coextensive and spaced apart remotely imageable layers which are configured to facilitate articulation between adjacent spaced apart layers and preferential longitudinal folding of the balloon.
