Eksigent Pump
Eksigent’s EKPump devices are designed for drug delivery and other medical device applications. EKPumps are ideally suited for these micro-pumping applications because of their small size, flexible configuration, and ease of use. The devices are currently in development for implantable and non-implantable drug delivery applications for both proteins and small molecules.

Features

  • Small, lightweight, inexpensive and disposable for inconspicuous attachment (1.5" in size and weighs 100 g)
  • No moving parts, and easy integration into devices.
  • Completely programmable for dosage levels, operating on a watch battery.
  • Accurate drug delivery due to accurate flow rates (+/- 2-5%), with constant flow rates backed by the positive pressure generation of the electrokinetic pump.

Technology

The electrokinetic pump, or EKPump, is a novel pump technology developed at Eksigent. EKPump™ devices for drug delivery control flow by application of an electrical potential across a fluid-filled porous medium, which generates a force that induces the liquid to flow. The figure below shows a capillary filled with EKPump media. Electroosmotic flow (EOF) is generated in the charge double layer that forms in the first few nanometers of the liquid/dielectric interface. Solvated ions move under the influence of an applied external field, carrying the bulk liquid by viscous drag.

The electroosmotically-driven flow rate, QEOF, is directly proportional to the applied voltage and the zeta potential of the porous EKPump device medium. The maximum pressure generated, PMAX, is inversely proportional to the square of the pump medium's pore diameter. Therefore, by optimizing the EKPump device medium's pore size and zeta potential, and controlling the applied voltage, electrokinetic flow control systems can be tailored to provide the appropriate pressure and flow characteristics required for a given application.
