PRESSURE-ACTIVATED PROXIMAL VALVES |
摘要 |
<p>A method for using a medical device in connection with a catheter for regulation or transfer of fluids to and from a patient. The method may include obtaining and using a medical device including a diaphragm having two unidirectional slit valves disposed therein that actuate in different directions, one slit valve actuating in one direction in response to infusion-induced pressure and another slit valve actuating in another direction in response to aspiration-induced pressure. The method may include infusing fluid through one of the unidirectional slit valves, through a lumen, and into a patient's body. The method may also include aspirating fluid from a patient's body through the lumen and another unidirectional slit valve.</p> |
