Abstract

A cutting balloon for use in a PTCA atherectomy procedure includes an elongated balloon that defines a longitudinal axis and is inflatable from a first deflated configuration to a second radially expanded configuration. One or more incising elements are mounted on the inflatable balloon. Compressible sheaths made of a relatively low durometer, flexible material are mounted on the balloon to protect the operative cutting surface of a respective incising element during assembly of the cutting balloon and transit of the cutting balloon to the treatment site. Each sheath extends farther from the longitudinal axis than the corresponding incising element and makes first contact with the tissue during a balloon inflation. Once contact has been established between the tissue and the sheath, further balloon inflation causes the sheath to radially compress between the tissue and the inflatable balloon exposing the operative cutting surface for tissue incision.

Claims (24)

1. A cutting balloon for use on a medical catheter to incise tissue at a treatment site in a body vessel of a patient, said cutting balloon comprising:
an elongated balloon defining a longitudinal axis, said balloon being inflatable from a first deflated configuration to a second radially expanded configuration;
an elongated incising element mounted on said balloon and oriented longitudinally, said incising element having a length and extending radially from said balloon to an operative surface feature capable of incising tissue; and a radially compressible sheath mounted on said balloon along the length of said incising element and extending radially from said balloon and beyond said surface feature when said balloon is in the first configuration to protect said surface feature during transit to the treatment site, said sheath being positioned for radial compression between said tissue and said balloon to expose said surface feature for tissue incision when said balloon is inflated into the second configuration.
2. A cutting balloon as recited in claim 1 further comprising a mounting pad for attaching said incising element to said balloon.
3. A cutting balloon as recited in claim 2 wherein said incising element is partially encapsulated in said mounting pad and said mounting pad is bonded to said balloon.
4. A cutting balloon as recited in claim 2 wherein said sheath is attached to said mounting pad.
5. A cutting balloon as recited in claim 1 wherein said sheath comprises a pair of sheath members positioned on said balloon to interpose said incising element between said sheath members.
6. A cutting balloon as recited in claim 5 wherein each said sheath member is formed as a hollow tube.
7. A cutting balloon as recited in claim 5 wherein each said sheath member extends a radial distance, d, from said balloon when uncompressed and said incising element extends a distance, D, from said balloon, with d >
D.
8. A cutting balloon as recited in claim 1 wherein said incising element is a blade and said surface feature is a cutting edge.
9. A cutting balloon as recited in claim 8 wherein said blade is partially encapsulated in a mounting pad, said mounting pad is bonded to said balloon, each said sheath member has an azimuthal width w, and wherein said blade has an azimuthal width, W, where said blade extends from said mounting pad, with w > 2W.
10. A cutting balloon as recited in claim 8 wherein said cutting edge of said blade is embedded in said sheath when said balloon is initially in said first configuration, said cutting edge oriented relative to said balloon to cut through said sheath for exposure of said cutting edge to incise tissue during radial compression of said sheath.
11. A cutting balloon as recited in claim 1 wherein said incising element is a round wire.
12. A cutting balloon as recited in claim 1 wherein said incising element is made of a hardened polymer.
13. A cutting balloon as recited in claim 1 wherein said sheath is made of a low durometer material.
14. A cutting balloon as recited in claim 1 wherein said sheath is made of a porous polyurethane material.
15. A cutting balloon for use on a medical catheter to incise tissue at a treatment site in a body vessel of a patient, said cutting balloon comprising:
an elongated balloon defining a longitudinal axis, said balloon being inflatable from a first deflated configuration to a second radially expanded configuration;
an elongated cutting blade mounted on said balloon and oriented longitudinally, said blade extending radially from said balloon to a cutting edge when said balloon is in said second configuration; and a sheath for protecting said cutting edge during transit to the treatment site, said sheath having a pair of sheath members with each sheath member being shaped as a hollow, elongated tube and positioned longitudinally on said balloon to interpose said blade between said sheath members, each said sheath member made of a flexible material to radially compress between said tissue and said balloon to expose said cutting edge for tissue incision during an inflation of said balloon.
16. A cutting balloon as recited in claim 15 further comprising a mounting pad for attaching said blade to said balloon.
17. A cutting balloon as recited in claim 16 wherein said blade is partially encapsulated in said mounting pad, said sheath is attached to said mounting pad, and said mounting pad is bonded to said balloon.
18. A cutting balloon as recited in claim 15 wherein each said sheath member extends a radial distance, d, from said balloon when uncompressed and said blade extends a distance, D, from said balloon, with d > D.
19. A cutting balloon as recited in claim 15 wherein each said sheath member is substantially rectangular shaped in a plane normal to said direction of tube elongation.
20. A cutting balloon for use on a medical catheter to incise tissue at a treatment site in a body vessel of a patient, said cutting balloon comprising:
an elongated balloon defining a longitudinal axis, said balloon being inflatable from a first deflated configuration to a second radially expanded configuration;
an elongated cutting blade mounted on said balloon and oriented longitudinally, said blade extending radially from said balloon to a cutting edge when said balloon is in said second configuration; and a sheath for protecting said cutting edge during transit to the treatment site, said sheath having a pair of elongated sheath members with each sheath member being mounted longitudinally on said balloon and shaped to expose a preselected portion of said cutting blade for tissue incision when said sheath members are radially compressed between said tissue and said balloon during an inflation of said balloon.
21. A cutting balloon as recited in claim 20 wherein said blade has a first side and a second side and each said sheath member is in contact with a portion of a respective side to define said pre-selected exposed portion of said cutting blade.
22. A cutting balloon as recited in claim 20 further comprising a mounting pad for attaching said blade to said balloon.
23. A cutting balloon as recited in claim 21 wherein said blade is partially encapsulated in said mounting pad, said sheath is attached to said mounting pad, and said mounting pad is bonded to said balloon.
24. A cutting balloon as recited in claim 20 wherein each said sheath member extends a radial distance, d, from said balloon when uncompressed and said blade extends a distance, D, from said balloon, with d > D.
