Abstract

This invention relates to the simplification of connection for catheter to venous access ports via the unique integration of expansion stem and compression shoulder features. This novel design minimizes the complication of procedural connection by reducing the number of components needed to obtain a secure attachment and removing the separate locking cap from the procedure.

ABSTRACT & FIGURES

This invention relates to the simplification of connection for catheter to venous access ports via the unique integration of expansion stem and compression shoulder features.  This novel design minimizes the complication of procedural connection by reducing the number of components needed to obtain a secure attachment and removing the separate locking cap from the procedure.  Traditionally, a catheter is placed over a stem and subsequently secured by a retaining cap; however, this invention details a single connector component that is pre-mounted to the port body and expands the catheter inside diameter and compresses/constrains the catheter outside diameter to create a connection.

EXEMPLARY EMBODIMENTS

This invention integrates the locking cap with the stem to make a single connection step for the physician during port implant. This invention adds an "integrated ID capture" to the stem to expand the catheter at a prescribed location and includes an "integrated OD capture" that replaces traditional locking cap of other VA ports. This connector can be comprised of single or multiple components, varying to accommodate ease of manufacturing or optimization of performance of individual features. In one preferred embodiment, the shoulder feature (colored pink in the image below), is molded from thermoplastic polyurethane that allows the integrated OD capture feature to flex to facilitate catheter attachm...
