SYRINGE ACTIVATED-VALVE FOR FLUSHING A CATHETER AND METHODS THEREOF

摘要

This application relates to a syringe-activated valve (100) for flushing a catheter for delivering an implant to an anatomical site, such as a patent foramen ovale in a patient and method thereof . In one embodiment, a catheter includes a proximal end, a distal end, a "Y" connector (320) at the proximal end, the "Y" connector having a guide wire port (301) and a connector port (310), a syringe activated valve having a first end and a second end, the second end of syringe-activated valve connecting to the connector port of the "Y" connector, and a syringe (200) connecting to the first end of the syringe-activated valve. Saline is injected by the syringe through the syringe-activated valve into the proximal end of the catheter, thereby flushing air from the catheter lumen out of the distal end of the catheter.
