A steering mechanism is preferably provided for orienting the device prior to operation of the anchoring mechanism. The anchoring mechanism and method are employed in drug delivery devices, brachytherapy devices or for anchoring a catheter or sheath to provide a working channel for reliable guidance of a wide range of tools to a target location within the body.

Abstract: The present invention provides a blood glucose system for treating a glucose metabolic disorder. The system includes a dosing device having a counter for generating a count and memory for storing dose quantities and counts, a blood glucose measuring device having memory for storing blood glucose measurements and measurement times, and a data processor for receiving data from the dosing device and blood glucose measuring device and converting counts to actual times. The data processor synchronizes the counts with the measurement times using a time standard.

Abstract: A medicine injector in which a barrel with a receiving cavity is adapted to slidably receive a syringe subassembly for axial movement therein. Upon removal of a safety and release of a syringe driver, the syringe driver moves forward and injects the syringe needle. Penetration controls are shown for controlling needle penetration depth. In one form the penetration control uses a sleeve and spring which are radially adjacent. A cushioning ring or other cushion may be used to reduce syringe breakage. A load distribution and guide ring may be used to distribute loading applied to the syringe and help guide the moving syringe.

Abstract: An I.V. flush syringe assembly includes a barrel having an inside surface defining a chamber for retaining fluid, an open proximal end and a distal end with a passageway therethrough in fluid communication with the chamber. An elongate plunger having a proximal end, a distal end and a flexible stopper is slidably positioned in fluid-tight engagement with the inside surface of the barrel for drawing fluid into and out of the chamber by movement of the stopper relative to the barrel. The barrel includes anti-reflux structure for holding said stopper in a partially deflected position after fluid has been delivered from the chamber and the stopper is being force against the distal end of the chamber.

Abstract: A fluid transfer assembly, drug container, and method for enabling fluid transfer in an infusion system is taught. The assembly includes a fluid container containing an infusion fluid, and a drug container. The fluid container has at least one inlet port for receiving a medical substance from the drug container. The assembly further includes at least one fluid barrier controlling fluid passage between the drug container and the fluid container. The inlet port exhibits a first luer-lock connector, and the drug container is sealed by a cap exhibiting a second luer-lock connector for attachment to the first luer-lock connector. The fluid barrier is designed and arranged to be ruptured by an external force to allow the fluid passage.

Abstract: The present disclosure relates to devices for injecting material into a body. The devices include a housing having a deployment cannula extending therefrom. The device also includes a rotary drive member wherein rotational movement of the drive member relative to the housing results in linear movement of an elongated injection member within a lumen of and out of a distal end opening of the deployment cannula. The elongated injection member includes a proximal end portion that may have a Tuohy-Huber tip and/or varying radii therealong.

Abstract: Syringe assemblies comprising a first cap and a second cap to ensure sterilization of the fluid path without the need for external packaging are described. Also described are methods of sterilizing the fluid path of a syringe assembly.

Abstract: An access port for providing subcutaneous access to a patient is disclosed. The access port includes a septum including palpable identification indicia thereon. In particular, the access port in one embodiment includes a body that defines a fluid cavity and a needle-penetrable septum covering the fluid cavity for providing access thereto. The septum defines an outer periphery. One or more palpation features are included on the septum. The palpation features each include a portion that extends in a radial direction beyond the outer periphery of the septum. The palpation features are therefore disposed relatively farther away from each other, simplifying palpation and identification thereof after the port has been subcutaneously implanted into a patient. The palpation features can be indicative of an attribute of the port, such as its ability to withstand fluid pressures and flow rates associated with power injection, for instance.

Abstract: A pen needle (101) for use with a drug delivery device (100) includes a hub body (113) having internal threads (216) to receive the drug delivery device (100). A post (121) is connected to the hub body (113). A needle (103) is rigidly fixed to the post (121). The post (121) is separable from the hub body (113) such that the needle (103) is removed with the post (121). The fluid path is not disturbed by such removal because the entire needle (103) is removed with the post (121). Removal of only the post (121) and needle (103) reduces the volume of waste required for disposal, thereby increasing the effective capacity of a sharps container.
