Abstract

Devices and systems disclosed herein may include a negative pressure pump that includes a reservoir defining a lumen and a longitudinal axis, a piston, and a drive assembly comprising a spring. Motion of the spring may move the piston along the longitudinal axis of the reservoir to create a negative pressure within the reservoir. Methods of manufacturing a negative pressure pump and using a negative pressure pump to remove fluid from a target site are also described.
