SYSTEMS AND METHODS FOR DELIVERING A THERAPEUTIC AGENT USING A CLAMPED ACTUATOR
First Claim
1. An apparatus, comprising:
- a reservoir configured to contain a fluid;
a fluid communicator configured to be placed in fluid communication with the reservoir; and
an actuator having a first end, a second end, and a medial portion between the first end and the second end, the actuator being configured so that when actuated, the actuator bends in the medial portion and produces a displacement of the second end in a first direction relative to the first end,the actuator being disposed with the first end constrained, the second end unconstrained, and oriented so that when the actuator is actuated, the second end is displaced toward the fluid reservoir and exerts a force on the reservoir such that fluid within the reservoir is communicated through the fluid communicator.

Abstract
A delivery system includes a reservoir, a fluid communicator, and an actuator. The reservoir is configured to contain a fluid and is in fluid communication with the fluid communicator. The actuator includes an unconstrained first end portion, an unconstrained second end portion, and a constrained medial portion therebetween. When the actuator is actuated the medial portion is configured to bend along a bend axis to produce a displacement of the first end portion and the second end portion relative to the medial portion. The bending of the actuator is configured to displace the actuator towards the reservoir to exert a force on the reservoir such that a fluid disposed within the reservoir is communicated through the fluid communicator.

8. An apparatus, comprising:
-
a housing removably couplable to a user; a reservoir configured to contain a fluid and disposed within the housing; an actuator having a constrained first end portion and an unconstrained second end portion; and a transfer structure disposed between the actuator and the reservoir, the transfer structure having a first end portion pivotally coupled to the housing and an unconstrained second end portion, the transfer structure having a surface configured to contact the reservoir upon actuation of the actuator, the actuator being configured such that when actuated, a force is exerted by the second end portion of the actuator onto the transfer structure and the unconstrained second end portion of the transfer structure pivots about a pivot location and exerts a force on the reservoir such that fluid within the reservoir is communicated out of the reservoir. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15)
