Abstract

A set comprises a needle (10) and a needle configuring catheter (18). The needle (10) has a hollow needle body (12) having a puncturing end (16). The needle body (12) is resiliently flexible so that in a relaxed state the needle body (12) tends to assume a straight configuration. The catheter (18) has a hollow catheter body (20) having a distal opening (24) and a portion (26) spaced from the distal opening (24) towards a proximal end of the catheter body (20). The catheter body (20) is resiliently flexible so that in a relaxed state the spaced portion (26) tends to assume a straight orientation having an axis and the distal opening (24) tends to assume a position offset from the axis of the spaced portion (26). The needle body (12) is insertable into the catheter body (20) such that an end portion (32) of the needle body (12) including the puncturing end (16) projects outwardly from the distal opening (24) of the catheter body (20).
