First Claim
Patent Images
1. A catheter assembly, comprising:
- a catheter including at least one lumen;
a connector including a distal end attached to a proximal end of the catheter and a passageway in fluid communication with the at least one lumen, a proximal portion of the passageway including an engagement feature configured to connect an end of an instrument to the connector, a distal portion of the passageway including a built-in valve longitudinally fixed with respect to the connector having a closed proximal end with a slit and an open distal end, the valve proximal end distal of the engagement feature; and
a tunneler, wherein the engagement feature engages a tip of the tunneler upon insertion of the tunneler tip into the proximal portion of the passageway.

Abstract
A multifunction adaptor for an open-ended catheter that allows placement of the catheter without risk of air embolism or blood loss through the open (proximal) end of the catheter body. The present design allows passage of a standard guidewire for “over the guidewire” placement techniques and a connection for catheter flushing using a standard syringe.
