Abstract
Abstract A catheter for use in angioplasty includes a shaft formed from an elongated metallic tube and has an inflatable balloon at its distal end. A plastic tube connects a distal end of the metallic tube to a proximal end of the balloon. The metallic and plastic tubes thus define a lumen for providing inflation pressure to the balloon. A metallic core member is attached to the metallic tube and extends distally therefrom through the plastic tube and balloon. The distal end of the balloon is sealably secured to the core member. A tip body is connected to the core member distally of the balloon, with a short guide wire lumen being defined on the tip body. The guide wire lumen is adapted to slidably receive a guide wire which then extends along the catheter exteriorly of the balloon.

Claim 1
Independent Claim
282 words
A balloon catheter comprising: a proximal hypotube shaft portion having a proximal end and a distal end and having a lumen extending therethrough; a distal shaft portion having a proximal end and a distal end, the proximal end of the plastic shaft portion being sealingly connected to the distal end of the hypotube shaft portion, the plastic shaft portion having an inner lumen extending therethrough, and the plastic shaft portion being more flexible than the hypotube shaft portion; a core member having a proximal end and a distal end, the core member being secured to the hypotube shaft portion to extend distally therefrom through the inner lumen of the plastic shaft portion, and the distal end of the core member terminating distally of the distal end of the plastic shaft portion; a balloon having a proximal waist and a distal waist, the proximal waist of the balloon being sealably connected to the distal end of the plastic shaft portion, the distal waist of the balloon terminating proximally of the distal end of the core member and being sealably connected thereto, and the interior of the balloon member being in fluid communication with the lumen of the hypotube shaft portion through the inner lumen of the plastic shaft portion; a distal tip body secured to that portion of the core member extending distally of the distal waist of the balloon, the tip body including a short guide wire lumen therein which is adapted to slidably receive a guide wire therethrough; and said distal tip body has a distal segment which has a tube defining the guide wire lumen, the axis of the tube being canted relative to the axis of the core member.
