Medical device with elastomeric bulb

摘要

A drainage catheter including a body, a drainage lumen extending between the body proximal end and the body distal end, the drainage lumen including a distal fluid inflow port and a proximal fluid drain coupling, and an inflation lumen extending between the body proximal end and the body distal end, conveying inflating fluid from a proximal fluid supply element to a distal fluid acceptor balloon, the proximal fluid supply element adjacent the proximal fluid drain coupling. A sleeve may be secured about the proximal fluid supply element and the proximal fluid drain coupling to provide a fluid impervious coating.
