ABSTRACT:
An apparatus is provided for facilitating substantially bloodless insertion into and withdrawal from a patient's body of a longitudinal member having a proximal end portion and having a distal end portion which is adapted to extend into the patient's body. The apparatus comprises a longitudinally extending sleeve having proximal and distal end portions and defining a lumen extending there along. The longitudinal member is positioned along the lumen. The sleeve has a line extending longitudinally along it which is either split or splittable so that the sleeve can be separated along the line for removal from about the longitudinal member while the distal end portion of the longitudinal member remains extended into the patient. A valve structure serves for preventing blood flow through the lumen. An access is present for allowing substantially bloodless insertion and withdrawal of the longitudinal member through the lumen.
