摘要： A multiple catheter assembly is provided (100). The assembly includes a first catheter (110) having a first proximal end region (112), a first distal end region (114) terminating in a first distal tip (116), and an outer surface (120) defining at least a first lumen (122) extending longitudinally therethrough between a first distal (118) and a first proximal opening. The assembly also includes a second catheter (130) having a second proximal end region (132), a second distal end region (134) terminating in a second distal tip (136), and a second outer surface (140) defining at least a second lumen (142) extending longitudinally therethrough between a second distal (138) and a second proximal opening. The first lumen and the second lumens are independent from each other for faciliting simultaneous flow in opposite directions. The outer surfaces of the first and second catheters are releasably joined for allowing the first and second distal tips and first and second proximal end regions to be at least partially longitudinally split from each other. A method of inserting the catheter assembly is also provided.

摘要： A multiple catheter assembly is provided. The assembly includes a first catheter constructed from a first material and having a first proximal end region, a first distal end region terminating in a first distal tip, and an outer surface defining at least a first lumen extending longitudinally therethrough between a first distal and a first proximal opening. The first proximal end region is integrally connected to an extension tube constructed from a second material. A second catheter is constructed from the first material and having a second proximal end region, a second distal end region terminating in a second distal tip, and a second outer surface defining at least a second lumen extending longitudinally therethrough between a second distal and a second proximal opening. The second proximal end region is integrally connected to an extension tube constructed from the second material. The first lumen and the second lumens are independent from each other for facilitating simultaneous flow in opposite directions. The outer surfaces of the first and second catheters are releasably joined for allowing the first and second distal tips to be at least partially longitudinally split from each other.

摘要： A co-axial catheter is disclosed. The catheter includes a first lumen having a first distal end, a first proximal end, and a longitudinal axis extending therethrough. The catheter further includes a second lumen having a second distal end and a second proximal end. The second lumen extends co-axially with the first lumen, wherein the second lumen is at least partially disposed within the first lumen. The second distal end extends distally of the first distal end. The second distal end includes a distal tip and a bulbous projection disposed between the distal tip and the first distal end. A method of manufacturing and of inserting the catheter is also disclosed.

The assembly also includes a needle hub having a distal hub end fixedly connected to the needle, a proximal hub end having an opening, and a passageway extending therethrough between the distal end and the proximal end. A valve is disposed within the passageway, wherein the valve comprises a sealing member having at least one through-opening disposed therein and a plunger disposed proximate the sealing member and slidable between a first position wherein the at least one through-opening is closed such that the hollow needle and the proximal hub end are not in fluid communication with each other and a second position wherein the plunger biases the at least one through-opening to an open position, such that the hollow needle and the proximal hub end are in fluid communication with each other. A method of using the needle assembly is also disclosed.
