Abstract: A liquid delivery device that is adaptive to animals' natural drinking habit and can be easily carried by animal owners. The liquid delivery device includes a moving member positioned at least partially in a chamber and the moving member is capable of moving laterally within the chamber.

Abstract: This invention relates to a syringe-activated valve 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 at the proximal end, the “Y” connector having a guide wire port and a connector port, 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 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.
