INJECTABLE MATERIALS DELIVERY DEVICES, SYSTEMS, AND METHODS
A transport and delivery system which may be used for injectable materials such as radioactive injectables. The system includes a base configured to hold a material transport device containing the injectable material, and a cover including a material delivery system and a material access device. The cover is configured to be mated over the base to result in alignment of the material access device with the material transport device to allow the material delivery system to deliver the injectable materials from within the material transport device to a patient. A priming cap may be provided to facilitate priming of the material delivery system and material access device to be substantially airless.
INSERTION DEVICE AND METHOD FOR INSERTING A MEDICAL DEVICE
An insertion device includes an insertion component that inserts a medical device into body tissue of a user. The insertion device also includes an insertion component retractor, a cap, a guide sleeve having a ramp, an insertion sleeve and an elastic member. For inserting the medical device, the cap, the insertion component retractor and the insertion sleeve are movable relative to the guide sleeve from a distal position to a proximal position. The ramp twists the insertion component retractor relative to the guide sleeve and the insertion sleeve when the cap is moved from its distal position to its proximal position. The cap is movable from its proximal position to its distal position and the insertion component retractor is thereby moved from its proximal position to its distal position. An associated method of using the insertion device is also disclosed.
INSERTION DEVICE
Embodiments relate to an insertion device that includes: a plunger coupled with a lock collar. The insertion device houses contents including: a striker including self-locking striker snap arm(s) where the striker is kept from firing by a striker spring captured between the plunger and the striker when the insertion device is in a cocked position; a sensor assembly; and a needle carrier that holds a piercing member, the needle carrier captured between the striker and a needle carrier spring where a self-releasing snap(s) keeps the needle carrier cocked, where the plunger prevents the self-releasing snap(s) from repositioning and releasing the needle carrier. The striker fires the needle carrier such that the self-locking striker snap arm(s) are positioned to allow the striker to snap down. The needle carrier is then retracted when the user releases the plunger and the piercing member is encapsulated within the insertion device.

APPARATUS AND METHODS FOR ADMINISTRATION OF MEDICINE INCLUDING MONITORING AND USER FEEDBACK
An apparatus including tubing sets, a modular constraint assembly, and methods of use are described for deliver a therapeutic medication to a patient, the apparatus can have a controller and a sensor. The controller is configured to receive data from the sensor, and to start and stop delivery of the therapeutic medication to the patient in response to data received from the sensor. In addition, apparatus, systems and methods are disclosed, which are configured to deliver a therapeutic medication to a patient. The apparatus, system and methods use a reservoir, a patient interface, a tubing set, a modular constraint assembly connected to the tubing sets, and a fluid pump, and the components are configured to provide a calibrated flow rate based upon specific characteristics of the therapeutic medications passing through and internal lumen of the tubing set.
METHOD OF MAKING LARGE NEEDLE INSERTION INTO AN ARTERY OR VEIN EASIER AND WITH LESS UNNECESSARY TRAUMA TO THE BLOOD VESSEL AND METHODS FOR MANUFACTURING SAME (NISE)
A method and devices for making needle insertion safer and easier (NISE). NISE or CISE device includes a small needle, cannula, and large needle in a nested assembly to provide less trauma to a target vessel during large needle insertion. The small needle is movable and within the cannula to a position exterior the cannula. The cannula is movable within the large needle. In a preferred assembly, the cannula is provided with a dulled tip having a beak and successive cutting edges along a tapered shape. The device can be provided in a stand-alone device or alternately integrated into existing off the shelf and currently available vascular devices.
Needle protective device for subcutaneous sensors
An introducer is provided for introducing a sensor into the body of a patient. The introducer connects to a sensor hub. When the sensor hub and introducer are connected, the introducer needle is exposed. When the sensor hub and introducer are disconnected, a needle cover and the needle move with respect to each other so that the needle cover substantially covers the needle, protecting a user from being injured by the needle.

Drawing drug from a vial
A substance delivery device engages with a reservoir, and includes a pump that draws therapeutic substance from the reservoir into a pump chamber of the delivery device without changing the internal dimensions of the reservoir. The volume of the therapeutic substance within the pump chamber varies in response to changes in the internal dimensions of the pump chamber. An orientation sensor generates an output indicating an orientation of the delivery device with respect to gravity. Control circuitry drives the pump to: calculate a volume of the substance within the reservoir, draw the substance into the pump chamber in response to (i) the calculated volume, in combination with (ii) an output from the orientation sensor that the delivery device is in an orientation that allows the substance to be drawn from the reservoir, and deliver the substance from the pump chamber to the subject. Other applications are also described.
PUNCTURE NEEDLE, CATHETER ASSEMBLY, AND VASCULAR PUNCTURE SYSTEM
A medical puncture needle includes: a metal needle body formed in a tubular shape, the needle body including: a blade surface located at a distal end portion of the needle body, a planar reflection portion located at an inner surface of the needle body and configured to reflect light, and a transmission window located proximal of the blade surface and configured to transmit reflected light reflected by the planar reflection portion.
