20110054285 | Flexible and Conformal Patch Pump - Provided is a flexible and conformal wearable, self-contained medical device. The medical device comprises an integral housing formed by a flexible upper portion and a flexible lower portion joined along their perimeters. The medical device is also provided in a plurality of shapes and configurations for increasing the flexibility and conformability of the housing. The components contained within the housing, such as a drug reservoir, printed circuit board, and power supply are preferably constructed from flexible materials and are formed, connected and positioned according to the configuration of the housing in a manner for enhancing flexibility of the housing. A thermal bubble micropump is provided for controlling flow of a drug from the flexible reservoir, that utilizes a thermal resistor provided locally to a thermal expansion fluid that causes a surrounding membrane to expand and displace a volume of drug to be provided to the user. | 03-03-2011 |
20110054390 | Extended Use Medical Device - Provided is an extended use self-contained, wearable medical device. The device is preferably configured with an infusion deployment mechanism for variably inserting and retracting an infusion needle to different depths, or completely retracting the infusion needle from the infusion site and then re-inserting the infusion needle after a predetermined period of time, throughout an infusion cycle for extending the viability of the infusion site. Another embodiment comprises dual needle deployment mechanisms which may also variably insert and retract the infusion needles. A flow sensor is preferably provided for detecting the stoppage of flow through the infusion cannula and signaling the needle deployment mechanism to attempt infusion at a different depth or to deploy a second infusion needle. A re-fillable reservoir assembly is preferably provided for supplying a drug over the extended use of the device. Another embodiment comprises a partially reusable and partially disposable medical device implementing the above features. | 03-03-2011 |
20110313357 | INFUSION SET AND/OR PATCH PUMP HAVING AT LEAST ONE OF AN IN-DWELLING RIGID CATHETER WITH FLEXIBLE FEATURES AND/OR A FLEXIBLE CATHETER ATTACHMENT - An infusion set, patch pump, or elements thereof, having an exemplary catheter ( | 12-22-2011 |
20120150123 | INFUSION SET - A single package infusion set is provided, including one or more of the following inserters: pushbutton-type, squeeze-type, contact-type, skin pinching-type, folding retraction-type, or multistage-type inserter having at least one reusable stage. The infusion set further includes adhesion means with user-selectable degrees of adhesion strength, self-sealing tube connection means, a lens feature to view, a site beneath the set, exemplary tube management and connection elements, insulin supply, adhesion concealment means, finger loops on the inserter and site preparation wipes or sprays, optionally provided as part of the inserter. The system further includes a package which may hold a number of easily released sets, retrievable by an inserter, an exemplary insertion needle handle and shroud, an exemplary squeeze-type latch between an upper portion and a lower portion of the set, and/or a tool removable upper portion of the set. | 06-14-2012 |
20150025473 | MEDICAL CANNULA PACKAGE - A package for a medical cannula with a hub, such as a pen needle, is disclosed. The package includes a cover for receiving a medical cannula and for engaging a hub of the medical cannula. The cover has open ends that are in communication through the cover. The packaging also includes a sterility barrier for the cover. | 01-22-2015 |
20150094666 | DUAL SHIELDED SYRINGE - A dual shield mechanism is provided for passive protection of a syringe cannula. The automatic shield system may be used with a re-fillable syringe, and may be adapted for filling the syringe from a vial using a novel vial adapter without triggering the passive shielding mechanism. | 04-02-2015 |
