Abstract
Embodiments of a permanent shunt are provided. According to one aspect of the invention, the shunt is a flexible biocompatible fluid directing lumen with first and second ends, with at least one of the first and second ends provided with a shape memory alloy adapted to cause the end to expand in dimension upon application of a predetermined amount of energy to cause fixation of the end of the shunt within an opening in the anatomy. According to another aspect of the invention, the shunt includes open first and second ends, a central portion therebetween, and an access port within said central portion, with the access port being smaller than the first and second ends.
