Abstract
A valve includes a valve seat and a valve stem. The valve seat includes a seat body defining a stem channel and a sealing element. The valve stem includes a stem body sized and configured for insertion into the stem channel having a proximal end, a distal end, and a surface extending therebetween. The stem body defines a channel extending from the proximal end to the distal end and defines at least one opening extending through the surface to the channel. A coupling element is formed over at least a portion of the surface of the valve stem and configured to provide advancement of the valve stem within the stem channel in a distal or proximal direction.
