  • Splittable tubular medical device and method for manufacture
    Patent number: 6508966
    Abstract: This invention relates to a splittable medical device incorporating two sets of preferential tear lines. The first set of preferential tear lines preferably includes two longitudinally extending skives formed along the exterior surface of the proximal portion of the splittable medical device. The second set of preferential tear lines preferably includes a plurality of grooves formed along a distal portion of the interior portion of the splittable medical device. The skives should be substantially aligned with some of the grooves.
