Abstract
An implantable shunt device having a primary catheter and at least two secondary catheters extending from the primary catheter is provided. The primary catheter includes a connecting end, an open end, and an inner lumen extending therebetween. Each of the secondary catheters extend from the connecting end of the primary catheter and include a fluid passageway formed therein in fluid communication with the inner lumen of the primary catheter. Each secondary catheter also includes at least one fluid entry port in fluid communication with the fluid passageway. In an exemplary embodiment, the fluid entry ports are disposed on an inwardly facing portion of each of the secondary catheters. The shunt device can be used for a variety of diagnostic and therapeutic procedures, including for the removal or introduction of fluid to a treatment site.
