摘要： A linear peristaltic pump equipped with a pressure relief mechanism for pumping I.V. fluids to a patient comprises a platen for supporting the tube, and a plurality of fingers which sequentially urge against the tube resting against the platen for creating a moving zone of occlusion. Cam lobes are formed to lift a penultimate and ultimate finger off of the tube at a rate faster than the other fingers to prevent pressure increases inside the tube which would otherwise be caused by other fingers urging against the tube. Additionally, the ultimate finger may be shortened with respect to the other fingers to reduce the total occlusion time of the ultimate finger to provide a more linearized flow of fluid to the patient.

摘要： A peristaltic pump for infusing medical solutions to a patient through a flexible tube comprises a pair of counter-rotating drive shafts mounted on a base. A separate roller is eccentrically mounted on each of the drive shafts and each roller has a wheel which is slidingly suspended at its periphery. A pair of curvilinear platens are each separately disposed concentric with a respective drive shaft to engage the tube between the wheel on each roller and the platen. Cooperative counterrotation of the drive shafts cause each roller to sequentially squeeze the tube against its respective platen to create a moving zone of occlusion along the tube.

摘要： A guide wire for advancing a medical device such as a catheter through a patient's body lumen which has an elongated core with proximal and distal core section, a flexible tubular member such as a coil on the distal end. The wire core includes surface textures that are translated into the overlying coating. Alternatively, the coating has its own surface texture. The surface textures include randomly or non-randomly spaced bumps, divots, ridges, helical grooves, longitudinal grooves, undulations, etc.

摘要： A locking component for locking a medical device onto a guide wire. Such medical devices include, for example, an embolic filter assembly used to capture embolic material that may be created and released into a patient's vasculature during a stenting or angioplasty procedure. The embolic filter assembly tracks along the guide wire, and is delivered to a treatment site where it is locked in place and deployed. The locking component enables the filter assembly to lock onto any standard guide wire, and does not require a modified guide wire that has a specially-designed fitting or stop to accomplish the locking function.

摘要： An apparatus for determining whether an IV infusion set has infiltrated the tissue of a patient includes a pump for pumping fluid through the IV set into the patient and a pressure transducer operably engaged with the IV set between the pump and patient. The pressure transducer is electrically connected to a microprocessor, and the microprocessor is electrically connected to the motor of the pump to control the pump to alternately withdraw from and infuse into the patient a predetermined volume of fluid.This predetermined volume of fluid is withdrawn from the patient by the pump at a preselected withdrawal pressure, while the pump infuses the predetermined volume of fluid into the patient at a preselected infusion pressure. The microprocessor measures both the time period for infusing the predetermined volume of fluid and the time period for withdrawing the predetermined volume of fluid. Based upon these time periods, the microprocessor evaluates whether the IV set has infiltrated the patient's tissue.
