| 20090240209 | Syringe Guard for Pre-Filled Medicament Vial - A device for expelling fluid from a pre-filled vial includes a hollow needle that is axially mounted on a syringe body. A guard, also mounted on the syringe body, is moveable between a first position wherein it is held to expose a distal portion of the needle and a second position wherein, after being released, it covers the distal portion. In operation, the vial is engaged in fluid communication with the needle, and it is then advanced on the syringe body. During this advancement, fluid is expelled from the vial through the needle, and the vial releases the guard for its movement from the first to the second position. | 09-24-2009 |
| 20090281492 | Syringe Guard with Selected Needle Configurations - A device for expelling a fluid through a needle mounted on a hub includes an elongated luer member that has a distal portion dimensioned to engage the needle hub to provide fluid communication between the luer member and the needle. An adapter anchors the luer member within the device. Slidingly mounted on the adapter is a cylindrical-shaped inverted plunger that is movable thereon between an advanced position and a withdrawn position. A needle guard is biased by a biasing member to extend distally from the luer member when the plunger is in the advanced position. The guard is selectively engageable with the plunger to be retracted to expose the distal portion of the luer member for fluid engagement with the needle hub when the plunger is moved to the withdrawn position. | 11-12-2009 |
| 20090286194 | TOOL FOR USE WITH A TOOTH REPOSITIONING MECHANISM - A tool for rotating a component on a mechanism, to achieve linear and rotational movement of an element on the mechanism, involves three subassemblies mounted on the tool. Firstly, a reference unit that can engage with the mechanism to establish a stationary datum. Secondly, a drive assembly that can be rotated relative to the datum. Thirdly, an engagement member, selectively engaged between the component and the drive assembly for rotation of the component. | 11-19-2009 |
| 20100262085 | Pre-Filled Plunger System and Method - An apparatus for delivering a fluid involving a syringe body, a needle, a guard, a biasing element, and a plunger is described. In some versions, the plunger may comprise a pre-filled cartridge. The pre-filled cartridge itself may therefore act as a plunger. In some versions, the needle may be in communication with the syringe body. The pre-filled cartridge may be operable to distally advance within the syringe body. During the advancement of the pre-filled cartridge, a fluid in the pre-filled cartridge may be released and the guard may be distally extended to cover at least a portion of the needle. | 10-14-2010 |
| 20100262086 | Passive Safety System with Pre-Filled Cartridge - An apparatus involving a syringe body, a needle, a guard, a biasing element, and a pre-filled cartridge is described. In some versions, the guard is able to move distally as a result of the movement of the pre-filled cartridge. In some versions, the biasing element is a spring. The spring may aid in the distal movement of the guard. In some versions, as the guard extends in the distal direction, the guard covers a portion of the needle. As the guard extends to cover a portion of the needle, the guard may help prevent accidental sticking from the needle. | 10-14-2010 |
| 20100262121 | Pre-Filled Cartridge Plunger Method - A method involving a syringe, a pre-filled cartridge, a needle, a guard, and a release mechanism is described. The method may involve inserting the cartridge into the syringe. In some versions, the method may involve releasing the guard to cover a portion of the needle. In some versions, the method may involve the release retaining the guard in a retracted position. In some versions, the release may be operable to be actuated to release the guard. In some versions, the guard may be extended and locked once extended to cover the needle. | 10-14-2010 |
| 20100262122 | Pre-Filled Syringe Having Internal Guard - A method involving a syringe, a plunger, a needle, and a guard is described. The method may comprise the guard moving and/or translating within the syringe. In some versions, the plunger may be inserted into a syringe body of the syringe. The plunger may be moved within the syringe body. In some versions, the guard may have a retracted position, and the guard may travel axially within the syringe body. In some versions, the guard may translate within the syringe body such that it touches the skin of the patient. In some versions, the guard may cover the needle by axial translation within the syringe body. | 10-14-2010 |
| 20100262123 | Pre-Filled Syringe Having Flexible Hinge - A method of using a syringe and a flexible member is described. In some versions, the method may involve providing a syringe, a needle, a pre-filled cartridge, an adapter, a flexible member, a biasing element, and a guard. The method may involve retaining the guard, releasing the guard by actuating the flexible member to translate the guard in the distal direction to cover the needle, and locking the guard. In some versions, the flexible member may have a first and second position for actuation. In some versions, the flexible member may engage and disengage the guard to retain and release the guard. | 10-14-2010 |
| 20100292655 | Passive Syringe with Internal Release - An apparatus having a syringe body, a plunger, a guard, a biasing member, a needle, and a release mechanism is described. In some versions, the release mechanism may include a flexible hinge mechanism. In some versions, the guard may have a retracted position and an extended position in communication with the flexible hinge mechanism. In some versions, the guard may have a first position and a second position in communication with a release mechanism. | 11-18-2010 |
| 20100331781 | SAFETY CATHETER - A device and method for positioning a catheter to establish a fluid access site into the vasculature of a patient includes a luer assembly that incorporates the catheter. Also included is a shuttle assembly that has a stylet for stiffening the catheter. In combination, the stiffened catheter and the shuttle assembly are held on a handle by the interaction of the luer assembly with the handle. Once the stiffened catheter is inserted into the vasculature, the luer assembly is separated from the handle and from the stylet, and is left in place. With this separation, the shuttle assembly is also released to be repositioned and concealed within the handle. | 12-30-2010 |
| 20110166528 | SAFETY CATHETER - A device and method for positioning a catheter to establish a fluid access site into the vasculature of a patient includes a luer assembly having a cannula or catheter, a shuttle assembly having a stylet for stiffening the catheter, and a holder assembly having an actuator for providing controlled retraction into a handle. The safety catheter comprises a flash window that allows a clinician to view when the vasculature of a patient has been properly accessed and to confirm that the stylet has been fully retracted into a safe position. | 07-07-2011 |
