What is a permacath?

A permacath, also known as a tunneled catheter, is a type of long-term vascular access device that is typically used for hemodialysis or other forms of medical treatment that require frequent access to the bloodstream.

Unlike temporary catheters that are inserted directly into a vein, a permacath is surgically implanted under the skin and tunneled subcutaneously to a large blood vessel, such as the jugular or subclavian vein. This design helps reduce the risk of infection and allows for long-term use, typically ranging from several weeks to several months.

Permacaths are made of biocompatible materials such as silicone or polyurethane, which are designed to be both durable and resistant to infection. They have multiple lumens, or channels, which allow for the simultaneous withdrawal and infusion of blood or fluids during medical procedures.

Overall, permacaths are an important tool for patients who require long-term vascular access for medical treatment, and they require proper care and maintenance to ensure optimal function and prevent complications.
