摘要： A method for inserting a multiple catheter assembly into a patient. The assembly includes a first catheter which includes a first distal end region, a first outer surface defining a first lumen, and a first transition region transitioning cross sections of the first outer surface and the first lumen. A second catheter includes a second distal end region, a second outer surface defining a second lumen, and a second transition region transitioning cross sections of the second outer surface and the second lumen. The outer surfaces of the first and second catheters are releasably joined by a splittable bond for allowing first and second distal tips of the assembly to be at least partially longitudinally split from each other. The method includes steps of separating the first and second distal end regions, and inserting the first and second distal tips through an incision and into an area to be catheterized.

摘要： A releasably locking dilator and sheath assembly and methods for releasing the dilator from the sheath and longitudinally splitting the sheath. The assembly includes a dilator having a dilator hub and a sheath having a sheath hub. The sheath hub may have a valve and has two opposing winged tabs, each tab having a perpendicular portion and an angled portion as well as a female threaded portion. The dilator hub has a male threaded portion designed to engage the female threaded portion of the sheath hub. The dilator is released from the sheath by rotating the dilator 90° in relation to the sheath and pulling the dilator out of the sheath. The sheath is longitudinally split by creating a couple on each of the winged tabs thereby forcing the sheath and the sheath hub to split longitudinally. With the sheath and sheath hub split longitudinally, the sheath is removed from around a catheter while leaving the catheter in place.

摘要： A releasably locking dilator and sheath assembly (10) and methods for releasing the dilator (12) from the sheath (14) and longitudinally splitting the sheath are provided. The assembly includes a dilator having a dilator hub (20) and a sheath having a sheath hub (40). The sheath hub has a valve (260,360) and has two opposing winged tabs (42), each tab having a perpendicular portion (44) and an angled portion (46) as well as a female threaded portion (53). The dilator hub (20) has a male threaded portion (30) designed to engage the female threaded portion of the sheath hub. The dilator is released from the sheath by rotating the dilator 90° in relation to the sheath and pulling the dilator out of the sheath. The sheath is longitudinally split by creating a couple on each of the winged tabs (42) thereby forcing the sheath and the sheath hub to split longitudinally. With the sheath and sheath hub and valve split longitudinally, the sheath is removed from around a catheter while leaving the catheter in place.
