SYSTEMS AND METHODS FOR DELIVERING A THERAPEUTIC AGENT

摘要

A delivery system includes a reservoir configured to contain a fluid and a fluid communicator configured to be placed in fluid communication with the reservoir. A first actuator is coupled to the reservoir and configured to exert a first force on the reservoir upon actuation. A transfer structure disposed between the first actuator and the reservoir is configured to engage the reservoir distribute the first force across a surface of the reservoir. A second actuator is disposed and oriented so that when the first actuator is displaced toward the fluid reservoir, the second actuator moves from a first configuration to a second configuration and exerts a second force on the transfer structure. The combination of the first and second forces collectively urge the transfer structure towards the reservoir such that fluid within the reservoir is communicated through the fluid communicator.
