SEEPING FLOW ANTI-CLOTTING BLOOD CATHETER

摘要

The device and methods described herein relate to a seeping flow catheter. The seeping flow catheter includes a porous material. The inner face of the porous material defines the lumen of the catheter. The porous material is configured such that fluid can flow along the length of the catheter, between the inner face and outer face of the porous material. As the fluid flows through the porous material, the fluid can seep into the lumen of the catheter through the inner face or out of the catheter through the outer face of the porous material. Portions of the inner or outer face can include a lining that substantial reduces the perfusion of the fluid through the lined areas.

主权项

1. A catheter comprising:
an elongated tube having a distal end and a proximal end, the elongated tube comprising: a porous material having an interior face and an exterior face, the interior face defining a lumen along a central axis of the elongated tube, wherein the porous material is configured to flow a fluid between the interior face and the exterior face of the porous material and to seep the fluid out of the porous material through the exterior face and interior face; and a first lining covering at least a portion of the exterior face and substantially limiting a perfusion through the exterior face at the portion of the exterior face covered by the first lining.
