Abstract
Abstract The present invention is a catheter needle and support assembly. That assembly includes a hollow bore catheter needle and a needle support assembly. The needle has a proximal port and a distal port an extends along a central needle axis between these port. A distal portion of the needle includes the distal port and extends along a first portion of the needle axis. A support portion extends along a substantially linear second portion of the needle axis between the first portion and the proximal port. The needle axis at the distal port is angularly offset from the second portion of the needle axis. The needle support assembly includes a coupling member and a pair of support members. The coupling member couples the needle support assembly to the support portion of the needle. The pair of support members extend from the coupling member. Each of the support members has a first flexible sheet portion extending form the coupling member and coupled to a second flexible sheet portion by a linear hinge portion extending along a hinge axis displaced from the coupling member.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
176 words
A catheter needle and support assembly comprising: A. a hollow bore needle having a proximal port and a distal port, said needle extending along a central needle axis between said proximal port and said distal port, said needle having a distal portion including said distal port and extending along a first portion of said needle axis, and having a support portion extending along a substantially linear second portion of said needle axis between said first portion and said proximal port, wherein said needle axis at said distal port is angularly offset by a needle angle from said second portion of said needle axis, B. a needle support assembly including: i. a coupling member including means for coupling said needle support assembly to said support portion of said needle, ii. a pair of support members extending from said coupling member, each of said support members having a first sheet portion extending from said coupling member and coupled to a second sheet portion by a linear hinge portion extending along a hinge axis displaced from said coupling member.
Claim 2
Dependent Claim
176 words
A catheter needle and support assembly comprising: A. a hollow bore needle having a proximal port and a distal port, said needle extending along a central needle axis between said proximal port and said distal port, said needle having a distal portion including said distal port and extending along a first portion of said needle axis, and having a support portion extending along a substantially linear second portion of said needle axis between said first portion and said proximal port, wherein said needle axis at said distal port is angularly offset by a needle angle from said second portion of said needle axis, B. a needle support assembly including: i. a coupling member including means for coupling said needle support assembly to said support portion of said needle, ii. a pair of support members extending from said coupling member, each of said support members having a first sheet portion extending from said coupling member and coupled to a second sheet portion by a linear hinge portion extending along a hinge axis displaced from said coupling member.
Claim 3
Dependent Claim
