![]() If they are bent accidentally or for tape-down purposes, blood flow is restricted, or worse, the catheters will kink and occlude. All work well when they are maintained in a straight fashion. ![]() They are the coaxial configuration, the side-by-side configuration and the triple-lumen configuration in which a third smaller lumen for placement over a guide wire is located in the partition between the two blood transmission channels. polygons, ellipsoids, wedges or shapes comprising concave and convex partsĬurrently, there are three basic catheter configurations available for temporary hemodialysis. A61M25/0032- Multi-lumen catheters with stationary elements characterized by at least one unconventionally shaped lumen, e.g.used for extracorporeal circuit treatment filters, plugs or valves characterized by lumina for withdrawing or delivering, i.e. A61M2025/0031- Multi-lumen catheters with stationary elements characterized by features relating to least one lumen located at the distal part of the catheter, e.g.A61M25/003- Multi-lumen catheters with stationary elements characterized by features relating to least one lumen located at the distal part of the catheter, e.g.A61M25/0026- Multi-lumen catheters with stationary elements.A61M25/0023- Catheters Hollow probes characterised by the form of the tubing by the form of the lumen, e.g.A61M25/0021- Catheters Hollow probes characterised by the form of the tubing.A61M- DEVICES FOR INTRODUCING MEDIA INTO, OR ONTO, THE BODY DEVICES FOR TRANSDUCING BODY MEDIA OR FOR TAKING MEDIA FROM THE BODY DEVICES FOR PRODUCING OR ENDING SLEEP OR STUPOR. ![]()
