SPLITTABLE MULTIPLE CATHETER ASSEMBLY

摘要

A multiple catheter assembly (300), comprising a first catheter (310) comprising a first lumen (311) and a first distal end region (312) terminating in a first distal tip (314), a second catheter (340) comprising a second lumen (341) and a second distal end region (342) terminating in a second distal tip (344), at least a portion of the first and the second catheters (310,340) residing in a cannulating portion (102), the first and second catheters (310,340) comprising a first and second catheter outer surface (120,140), respectively, defining a cross-section at the first and second distal tips (314,344) and a cross-section in the cannulating portion (102), the first and second lumens (311,341) defining a cross-section at the first and second distal tips (314,344) and a cross-section in the cannulating portion (102), the first and second distal end regions (312,342) comprising a first and second transition region (119,139), respectively, transitioning the first and second catheter outer surfaces (120,140) from the cross-section defined by the outer surfaces (120,140) at the distal tips (314,344) to the cross-section defined by the outer surfaces (120,140) in the cannulating portion (102), the transition regions (119,139) further transitioning the first and second lumens (311,341), respectively, from the cross-section defined by the lumens (311,341) at the distal tips (314,344) to the cross-section defined by the lumens (311,341) in the cannulating portion (102).
