Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
162 words
A balloon/delivery catheter assembly comprising: a balloon catheter having a distal balloon catheter end portion with an expandable balloon fluidly coupled to an inflation coupler, said balloon catheter having a first port proximal of said balloon and a second port distal of said balloon, and a balloon catheter lumen extending between said first and second ports; a delivery catheter having a polymeric delivery shaft with a delivery lumen extending between a proximal port and a distal port, said distal balloon catheter end portion being coaxially positionable with a friction fit and exterior to at least a portion of said polymeric delivery shaft; and a positioner having a positioner shaft and a positioner cuff and wherein said positioner shaft ends distally in said positioner cuff, and further said positioner cuff defines a positioner lumen such that said positioner cuff is coaxially slidable along at least a portion of said polymeric delivery shaft and is adapted to engage said distal balloon catheter end portion.
Claim 2
Dependent Claim
162 words
A balloon/delivery catheter assembly comprising: a balloon catheter having a distal balloon catheter end portion with an expandable balloon fluidly coupled to an inflation coupler, said balloon catheter having a first port proximal of said balloon and a second port distal of said balloon, and a balloon catheter lumen extending between said first and second ports; a delivery catheter having a polymeric delivery shaft with a delivery lumen extending between a proximal port and a distal port, said distal balloon catheter end portion being coaxially positionable with a friction fit and exterior to at least a portion of said polymeric delivery shaft; and a positioner having a positioner shaft and a positioner cuff and wherein said positioner shaft ends distally in said positioner cuff, and further said positioner cuff defines a positioner lumen such that said positioner cuff is coaxially slidable along at least a portion of said polymeric delivery shaft and is adapted to engage said distal balloon catheter end portion.
Claim 3
Dependent Claim
31 words
The assembly of claim 1, wherein said positioner cuff is adapted to removeably engage said distal balloon catheter end portion by abutting an end of said distal balloon catheter end portion.
Claim 4
Dependent Claim
38 words
The assembly of claim 1, wherein said positioner cuff is coaxially slideable over said expandable balloon and is adapted to removeably engage said distal balloon catheter end portion by expansion of said balloon internally of said positioner lumen.
Claim 5
Dependent Claim
13 words
The assembly of claim 1, wherein said positioner shaft is a metal wire.
Claim 6
Dependent Claim
36 words
The assembly of claim 1, wherein said balloon catheter lumen comprises a threaded inner surface and said polymeric delivery shaft comprises a threaded outer surface that is adapted to threadedly couple with said threaded inner surface.
Claim 7
Dependent Claim
32 words
The assembly of claim 5, wherein said positioner cuff is adapted to removeably engage said distal balloon catheter end portion and to impart rotational forces to said distal balloon catheter end portion.
Claim 8
Dependent Claim
37 words
The assembly of claim 1, wherein said balloon catheter further has an inflation shaft with an inflation lumen having a first longitudinal axis and said delivery lumen has a second longitudinal axis different from said first-longitudinal axis.
Claim 9
Dependent Claim
19 words
The assembly of claim 7, wherein said inflation shaft is more flexible than said distal balloon catheter end portion.
Claim 10
Dependent Claim
20 words
The assembly of claim 7, wherein said inflation shaft has an outer diameter in the range of 0.008" to 0.020".
Claim 11
Dependent Claim
28 words
The assembly of claim 7, wherein said inflation shaft comprises a material chosen from the group consisting of low density polyethylene, low durometer polyurethane, fluoropolymers, or blends thereof.
