SYRINGE AND METHOD FOR INFLATING LOW VOLUME CATHETER BALLOONS

摘要

A low volume syringe provides easy, precise delivery of a small amount of fluid for proper inflation of a low volume surgical balloon to occlude emboli. The syringe includes a stop mechanism which limits both the intake and the explusion of fluid contained in the syringe. An elongated cylindrical body allows a user room for error in measuring the delivery of the volume of fluid. The low volume syringe may be used with a larger capacity syringe and a three-way valve to regulate inflation of the low volume catheter balloon. An inflation adaptor may be used to open and close a catheter valve at the proximal end of the hollow catheter. The reservoir syringe is used in a preferred arrangement for evacuating the balloon, catheter and connector prior to insertion of the balloon catheter into the patient at a desired vascular site, and may also be used for deflation of the balloon prior to removal from the patient.
