Compliant catheter adapter having self-slitting needle
First Claim
1. A compliant catheter adapter comprising:
- a needle comprising;
a proximal end, the proximal end of the needle shaped to facilitate a self-slitting/self-guiding process during assembly of the catheter adapter;
a distal end; and
a plurality of openings disposed along the needle between the proximal end and the distal end of the needle, wherein the plurality of openings are configured to facilitate flashback visualization;
a catheter adapter body formed of a compliant material, the catheter adapter body comprising;
a proximal end and a distal end, the catheter adapter body having a generally elongate shape formed about a longitudinal axis extending between the proximal end and the distal end of the catheter adapter body;
an inner chamber disposed within the catheter adapter body, the inner chamber having a generally elongate shape formed about the longitudinal axis extending between the proximal end and the distal end of the catheter adapter body;
a compression resistant septum comprising a distal end formed in the compliant material of the catheter adapter body, the compression resistant septum further comprising a proximal end, wherein the distal end of the compression resistant septum and the catheter adapter body are integrally formed of the same compliant material, the compression resistant septum disposed toward the proximal end of the catheter adapter body; and
a lumen formed through the compression resistant septum by the proximal end of the needle during the self-slitting process as the catheter adapter is assembled; and
a compression cap coupled to the proximal end of the compression resistant septum, the compression cap configured to impart a radial compression force to the compression resistant septum such that the lumen narrows and seals when the needle is removed from the lumen.

Abstract
A self-slitting open lumen cannula may be used with catheter adapters to reduce manufacturing complexity and costs, as well as improve the safety of the catheter adapters against fluid leakage. The open lumen cannula may also include one or more notches to facilitate flashback visualization. The catheter adapters may further include a catheter adapter body formed of a compliant material that houses one or more compression resistant septa with at least one lumen formed by the proximal end of the needle during a self-slitting process as the catheter adapter is assembled. The compression resistant septum may also be coupled to a compression cap that imparts a radial compression force on the one or more compression resistant septa such that the at least one lumen narrows and seals when the cannula is removed.
