SteadyMed Ltd. is an Israeli startup developing the PatchPump™, a subcutaneous medication delivery button, that the company describes as "light and inexpensive patch-sized miniature infusion pump." What's more is that the device promises to be able to inject both basal rates and user-initiated boluses of meds.
The company says that its PatchPump™ works using a "novel solid-state battery cell which gradually expands in a stable manner under electronic control."
A couple of nuggets about the technology and capabilities of device as provided by the company:
The ECell™ merges the two major components of disposable pumps -- the power source and the motor -- into one simple miniature part, enabling the fabrication of very flat and simple devices.The key advantages of the technology are as follows:
Rock-steady drug-delivery using non-gassing mechanism
Self-powered as battery cell expands as it is depleted
Unaffected by changes in temperature or pressure
Very low cost
Lightweight
No MEMS or other exotic manufacturing technologies required
The expanding battery cell will be produced on a battery production line
SteadyMed's product range enables:
Delivery of basal and bolus combinations as required
A range of drug volumes: 5cc, 3cc, 2cc, 1cc, 0.5cc
Typical operation time 48 hours to 7 days
Penetration methods include SubQ, IV and microneedles
Integration of soft cannula insertion mechanism into the device
No MEMS or other exotic manufacturing technologies required
Varying levels of sophistication of electronic controller, from simple and disposable to re-usable and sophisticated
