Patent application number | Description | Published |
20130289482 | IMPLANTABLE DRUG-DELIVERY DEVICES, AND APPARATUS AND METHODS FOR REFILLING THE DEVICES - In various embodiments, a needle is employed in refilling drug-delivery devices. | 10-31-2013 |
20140074062 | PISTON PUMP DEVICES - Drug pump devices with syringe or pen-injection configurations may utilize pre-filled drug vials or cartridges; the prefilled vials may be equipped with mechanisms for stirring their contents and/or changing a chemical environment therein to improve therapies. To facilitate combination therapies, multiple drug pump devices may be assembled into a larger system. Lancet insertion devices for use in conjunction with the drug pump devices may feature improved safety characteristics and/or mechanisms for minimizing pain and discomfort. | 03-13-2014 |
20140088508 | DRUG-DELIVERY DEVICES WITH INTEGRATED NEEDLE-INSERTION MECHANISM - Drug-delivery devices for subcutaneous injections may be provided with pre-filled drug reservoirs and/or integrated needle-insertion mechanisms to increase ease of use of the devices. Certain device configurations include a needle disposed above or below the drug vial, parallel to the bottom wall of the device, with the needle-insertion mechanism placed at least partially side-by side with the vial. | 03-27-2014 |
20140088554 | DRUG-DELIVERY PUMP WITH INTELLIGENT CONTROL - Embodiments of the present invention utilize a closed-loop feedback control system to ensure accurate drug delivery. This control system may, for example, utilize a flow sensor to measure the volume of delivery and an intelligent control algorithm to anticipate and compensate for overdoses and underdoses. Feedback control systems in accordance herewith can be applied to any piston- or plunger-driven pump system utilizing sensors that measure flow directly or indirectly. Depending on the mode of operation, fluid may be dispensed continuously or in discrete pulses, and the manner of adjustment or calibration may be tailored to the operational mode in use. | 03-27-2014 |
20140088555 | Systems and Methods for Electrolysis Pump Control - Drug-delivery devices may utilize electrolysis pumps to push a plunger so as to deliver drug from a reservoir. The volume and/or rate of drug delivery may be monitored based on pressure measurements in the pump chamber. Pressure signatures characteristic of end-of-dose and occlusion events may be used to detect when plunger movement stops. | 03-27-2014 |
20140094770 | DRUG-DELIVERY PUMP WITH INTELLIGENT CONTROL - Embodiments of the present invention utilize a closed-loop feedback control system to ensure accurate drug delivery. This control system may, for example, utilize a flow sensor to measure the volume of delivery and an intelligent control algorithm to anticipate and compensate for overdoses and underdoses. Feedback control systems in accordance herewith can be applied to any piston- or plunger-driven pump system utilizing sensors that measure flow directly or indirectly. In some embodiments, adjustments are made during a “priming” stage when liquid is pumped through the internal fluid path but does not exit the pump. | 04-03-2014 |
20140094771 | DRUG-DELIVERY PUMP WITH INTELLIGENT CONTROL - Embodiments of the present invention utilize a closed-loop feedback control system to ensure accurate drug delivery. This control system may, for example, utilize a flow sensor to measure the volume of delivery and an intelligent control algorithm to anticipate and compensate for overdoses and underdoses. Feedback control systems in accordance herewith can be applied to any piston- or plunger-driven pump system utilizing sensors that measure flow directly or indirectly. In some embodiments, adjustments are made based on the flow “tail” that occurs in a piston- or plunger-type pump as relaxation of the plunger material continues to push fluid out of the drug reservoir; this residual flow eventually ceases after the plunger returns to its natural state. | 04-03-2014 |
20140196798 | DIAPHRAGM CHECK VALVES AND METHODS OF MANUFACTURE THEREOF - Microscale valves for use in, e.g., micropump devices, may be formed of a slitted diaphragm bonded to the interior of a valve tube. A bump in the diaphragm and/or a backward-leakage stopper may increase the breakdown pressure of the valve. A push-rod may be used to pre-load the valve membrane to thereby increase the cracking pressure. | 07-17-2014 |
