BALLOON CATHETER WITH CENTRALIZED VENT HOLE
First Claim
1. A catheter assembly for engaging a stenosis, the assembly comprising:
- a catheter including a wall having a proximal end and a distal end disposed along a longitudinal axis, the wall having an interior surface and an exterior surface, the interior surface defining a first lumen and a second lumen spaced apart and disposed about the longitudinal axis, the wall defining an opening extending between the inner surface and the exterior surface, the opening being in communication with the first lumen so as to define a flow path having an angle incident to the longitudinal axis;
a first marker disposed about the exterior surface along the longitudinal axis; and
a second marker disposed about the exterior surface along the longitudinal axis, the first and second markers being spaced from one another along the longitudinal axis so as to be substantially equidistant from the opening; and
a balloon having a first end and a second end defining a holding volume therebetween, the first end and the second ends being sealed about the exterior surface, the opening is disposed within the holding volume so as to place the first lumen in sealed fluid communication with the holding volume, the first and second ends being spaced substantially equidistantly about the opening along the longitudinal axis.

Abstract
A system and method providing a catheter assembly for engaging a stenosis. The assembly includes a catheter defining a first lumen and a second lumen spaced apart and disposed about a longitudinal axis. The catheter includes an opening in communication with the first lumen to define a flow path having an angle incident to the longitudinal axis. A first marker; and a second marker disposed on the catheter are spaced equidistantly from the opening. The assembly includes a balloon having a first end and a second end each sealed about the catheter and equidistantly from the opening to define a holding volume therebetween. The opening is disposed within the holding volume thereby placing the first lumen in sealed fluid communication with the holding volume. In a preferred embodiment, the catheter assembly includes a stent disposed about the balloon, and the balloon is configured to engage the stent with a stenosis.

16. A fluid delivery device comprising:
-
an elongated member having a proximal end and a distal end defining a first lumen and a second lumen spaced apart from the first lumen along a longitudinal axis, the first lumen being configured to convey a fluid, the member having an opening disposed between the proximal and distal ends, the opening being in fluid communication with the first lumen; and a first marker and a second marker, the first marker and second marker being disposed about the member and spaced from one another so as to be substantially equidistant from the opening. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

25. A method of expanding a stenosis, the method comprising:
-
locating a first marker of a catheter assembly to one side of a portion of a stenosis and locating a second marker on the opposite side of the portion such that the first and second markers are equidistant from the portion of the stenosis so as to align a substantially central region of an inflatable member with the portion; and introducing a sufficient amount of the fluid into the inflatable member to expand the inflatable member substantially equally and radially about the central region to engage and apply an expansion force to the portion. - View Dependent Claims (26)

27. A method of dilating a stenosis, the method comprising:
-
locating a first marker of a catheter assembly to one side of a portion of a stenosis and locating a second marker on the opposite side of the portion such that the first and second markers are generally equidistant from the portion of the stenosis; disposing a fluid fill opening of an inflatable member generally equidistant between the first and second markers; and expanding the inflatable member via the fluid fill opening substantially equally longitudinally and radially about the central region to engage and apply an expansion force to the portion.
