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.
