Abstract
A cage can be positioned around a medical balloon, such as an angioplasty balloon, to assist in a medical procedure. The cage can include a plurality of strips, each extending between a set of rings including first and second rings. As the balloon expands, the first and second rings move closer together and allow the strips to expand outward. The cage may have wedge dissectors on the strips.
Claims19
A medical balloon catheter, comprising:
- an elongate member;
- a balloon connected to the elongate member, wherein the balloon comprises cones about lateral ends of the balloon, wherein the balloon comprises an overall working balloon length that does not include lengths of the cones;
- and
- a strip extending longitudinally along an outer surface of the balloon, wherein the strip comprises a plurality of wedge dissectors spaced apart by a plurality of segments of a top planar surface of the strip, wherein the strip comprises a strip length longitudinally along the strip, wherein the strip comprises a strip width transverse to the strip length,
- wherein each wedge dissector comprises a base bounded to the strip, wherein each wedge dissector comprises a wedge dissector length longitudinally along the wedge dissector at the base of the wedge dissector, wherein each wedge dissector comprises a wedge dissector width transverse to the wedge dissector length at the base of the wedge dissector,
- wherein each wedge dissector comprises an outward facing surface, wherein each outward facing surface comprises an outward facing surface length longitudinally along the wedge dissector, wherein each outward facing surface comprises an outward facing surface width transverse to the outward facing surface length, wherein the strip comprises a first curvature extending between each segment of the top planar surface of the strip and each wedge dissector, wherein the strip comprises a second curvature forming the outward facing surface of each wedge dissector, wherein the second curvature is different than the first curvature,
- wherein each segment of the top planar surface has a greater length than the wedge dissector length at the base of the wedge dissector, wherein the top planar surface extends between each of the plurality of wedge dissectors;
- wherein ends of the strip comprise no wedge dissectors enabling the strip to be most flexible where forces are highest during migration to and from a site of deployment.

A medical balloon catheter, comprising:
- an elongate member;
- a balloon connected to the elongate member;
- and
- a strip extending longitudinally along an outer surface of the balloon, wherein the strip comprises a plurality of wedge dissectors spaced apart by a plurality of segments of a top planar surface of the strip, wherein the plurality of wedge dissectors comprise at least ten wedge dissectors with segments of the top planar surface therebetween, wherein the plurality of wedge dissectors are evenly spaced, wherein the strip comprises a strip length longitudinally along the strip, wherein each segment of the top planar surface has the same length, wherein the strip comprises a strip width transverse to the strip length,
- wherein each wedge dissector comprises a base bounded to the strip, wherein each wedge dissector comprises a wedge dissector length longitudinally along the wedge dissector at the base of the wedge dissector, wherein each wedge dissector has the same wedge dissector length, wherein each wedge dissector comprises a wedge dissector width transverse to the wedge dissector length at the base of the wedge dissector,
- wherein each wedge dissector comprises an outward facing surface, wherein each outward facing surface comprises an outward facing surface length longitudinally along the wedge dissector, wherein each outward facing surface comprises an outward facing surface width transverse to the outward facing surface length, wherein the strip comprises a first curvature extending between each segment of the top planar surface of the strip and each wedge dissector, wherein the strip comprises a second curvature forming the outward facing surface of each wedge dissector, wherein the second curvature is different than the first curvature,
- wherein the strip width enables the strip to be laid down tangential to the balloon or contained in a fold of the balloon during folding,
- wherein the strip maintains a low profile on the outer surface of the balloon, aiding in limiting the plurality of wedge dissectors from damaging tissue during delivery,
- wherein the strip comprises a flat bottom to sit on the outer surface of the balloon enabling perpendicularity of the plurality of wedge dissectors to the outer surface of the balloon.
