Abstract:
A system for delivering fluid to a user transcutaneously includes a subcutaneous infusion cannula base assembly, a cannula inserter assembly and a fluid connection assembly. The subcutaneous infusion cannula base assembly is configured to be located on the user's skin. The cannula inserter assembly is coupled to the cannula base assembly and is configured to drive an infusion cannula through the user's skin in a nominally helical trajectory. The fluid connection assembly is configured to fluidically connect the cannula base assembly to a source of delivery fluid. Cannula and stylet assemblies configured for helical or non-helical insertion are also disclosed.

Claim (Index 23):
A system for delivering fluid to a user transcutaneously, the system comprising:\n a subcutaneous infusion cannula base assembly configured to be located on the user's skin, the cannula base assembly including an infusion cannula formed from a polyether block amide thermoplastic elastomer and having a central lumen therethrough, wherein the cannula has a nominal outside diameter no greater than 0.56 mm, wherein the cannula includes a reinforcing coil extending along a portion of the central lumen, wherein the reinforcing coil has a nominal inside diameter and a nominal outside diameter and wherein the nominal outside diameter is the same as a nominal inside diameter of the central lumen it resides in, wherein the reinforcing coil has a first section with a first coil pitch and a second section with a second coil pitch, the first section being located more distally in the cannula than the second section, wherein the first coil pitch is an open pitch and the second coil pitch is a closed pitch and wherein the first section includes a plurality of holes though a side wall of the cannula, wherein the cannula includes a distalmost section having an outer taper of between 10 and 30 degrees and no reinforcing coil located in the distalmost section, wherein a portion of the cannula is siliconized to reduce insertion force; a cannula inserter assembly coupled to the cannula base assembly, the inserter assembly including a sharp stylet configured to pass through the central lumen of the cannula, wherein the stylet has a nominal outside diameter that is the same as the nominal inside diameter of the reinforcing coil, wherein the stylet has a sharpened distal tip that extends from the distalmost section of the cannula, the inserter assembly being configured to drive the stylet and cannula together through the user's skin without a needle placed over the cannula; and a fluid connection assembly configured to fluidically connect the cannula base assembly to a source of delivery fluid.
