Claim 8

Dependent Claim 70 words

A method according to claim 5, wherein said clip member, said luer member and said elongate member are arranged such that said elongate member is disposed within the guidewire lumen, and at an angle relative to the guidewire lumen of the catheter when said clip member is coupled to the container storing the catheter, for allowing the connection of an injection device without interference from the container or the catheter.

Claim 9
