BALLOON CATHETER FOR INTRAVASCULAR THERAPIES
First Claim
Patent Images
1. A catheter for use in intravascular procedures, the system comprising:
- a tubular element having a proximal end and a distal end, a first helical cut and a second helical cut, wherein said first cut is out of phase from said second cut so that said cuts do not intersect;
a polymer jacket disposed about the tubular element; and
an elastomeric balloon bonded to said polymer jacket.

Abstract
A low profile, tailored stiffness intravascular balloon catheter is disclosed for use especially in treatment of intracranial aneurysm. Treatment utilizing the device can be performed without the need for a guide wire during delivery of embolic implants. A profiled metal hyptotube that is machine-cut or laser cut in a dual, off-set helical pattern, is the foundation for the device. A polymer jacket may be disposed upon the hypotube. A thin wall elastomeric balloon is bonded to the distal end of the system in fluid communication with the hypotube. The system may have one or more delivery ports for the release of embolic implants.

16. A method of manufacture of a catheter comprising the steps of:
-
providing a metal tubular member having a cylindrical wall; cutting a first helix through the wall of the tubular member; cutting a second out-of-phase, non-intersecting helix through the wall of the tubular member; affixing a polymer jacket over the exterior of tubular member; and attaching an inflatable elastomeric balloon to a distal end of the tubular member or polymer jacket. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
