Abstract: A medical device has a distal member with a configuration that can be changed by means of a control handle with a control assembly employing a rotational cam, a shaft, and a pulley, where the rotational cam is rotationally mounted on a portion of the control handle for rotation by a user. The rotational cam operates on the shaft to move it proximally or distally depending on the direction of rotation which in turn rotates the pulley to draw or release a puller wire to change the configuration of the distal member of the medical device. The shaft is oriented along a diameter of the control handle. The shaft has two ends which extends through two axial guide slots in the portion of the control handle to sit two opposing helical tracks formed on inner surface of the rotational cam. The guide slots are parallel with the longitudinal axis of the control handle and therefore maintain the shaft's diametrical orientation as the rotational cam is rotated to move the shaft proximal or distally.

Abstract: Some embodiments of an infusion pump system can employ a number of power management techniques to avoid using substantially excessive power during operation of the pump drive system. Thus, the infusion pump system can draw upon the energy supply in an efficient manner that extends the useful life on the power supply. Furthermore, the infusion pump system can be configured estimate an amount of power remaining to operate the pump system without the requirement of directly detecting the remaining charge on power supply device (e.g., without detecting the remaining charge on a battery). As such, the infusion pump system can readily inform a user of a particular estimated amount of time remaining for medicine dispensing operations.

The medical injector further includes a needle having a sharpened first end and a second end in communication with the reservoir, a first cap covering the sharpened first end of the needle, and a second cap covering at least a part of the first cap. The second cap is engaged with the first cap such that removal of the second cap simultaneously removes the first cap from the first end of the needle.

Abstract: A drug delivery device for delivery of medicament having a delivery pump system and a cartridge system, the delivery pump system operating electromagnetically by driving two disk magnets that are housed within pump body inserts of the cartridge system. The displacement of the magnets and an elastomer membrane placed between the magnets of the cartridge system results in a volumetric change within two reservoirs and the flow of medicaments. The medicament flows from the reservoirs to the inlet/outlet members via the pump body inserts and discharged to a patient user's body through an infusion set.

Abstract: A syringe includes a barrel and a rotatable element on the barrel, for example, at a proximal location along the length of the barrel. The rotatable element rotates at least partially around the barrel. When a handle is associated with the rotatable element, the barrel may rotate as the handle is held substantially stationary or the handle may be rotated while the barrel and any peripheral device secured thereto remain substantially stationary. When handles are associated with a rotatable element that may be removed from a barrel, a barrel that is disassembled from the rotatable element may be replaced with another barrel of the same or a different configuration. The barrel and plunger may be configured to cause the barrel to rotate as the plunger moves along the length of the barrel. Methods of using a syringe with a rotatable element on a barrel thereof are also disclosed.

Abstract: A simplified insulin pump allows type II diabetics to identify routine patterns in their daily lifestyle that provide a generally accurate typical pattern of activity and meals. An infusion regimen can be programmed into the pump that generally correlates with this typical pattern to provide a viable treatment option for a type II diabetic without the need for specific and precise matching of insulin to carbohydrate consumption or activity level.

Abstract: An anti-reverse apparatus includes a latch capable of stopping an end sealing piece from moving reversely, and a loose switch capable of relieving a stop action by the latch on the reverse movement of the end sealing piece. Limitation of the latch on the reverse movement of the end sealing piece can be relieved by pressing the loose switch down. When the end sealing piece is detachably mounted at a near end of a sleeve in a rotating manner, the latch can stop reverse movement causing loosening of the end sealing piece and prevent air leakage or the end sealing piece from loosening from the near end of the sleeve. When the loose switch is pressed down, limitation of the latch on the reverse movement of the end sealing piece can be relieved, and the end sealing piece can be detached from the near end of the sleeve.

The processor arrangement is configured when the supplemental device is in a default mode to display both a quantity of medicament that was delivered since a last dose and a time elapsed since delivery of the last dose.

Abstract: An injection analgesia system advantageously numbs a patient's skin around an injection site. An injection window guides a caregiver's injection placement to a relatively small area while allowing standard injection procedures to be followed, such as stretching the skin and puncturing the site with a jabbing motion. The injection analgesia system has a needle shield and an analgesia, which are layered together and applied to a skin surface. A needle shield window and a analgesia window align to form the injection window. Advantageously, the needle shield may fold and/or wrap around the injection needle for sharp object protection during and after needle disposal.

Abstract: A resettable dosing mechanism comprises a dose button and a dial grip operatively coupled to the dose button. A spindle acts on a bung of a cartridge and a driver is operatively coupled between the dose button and the spindle. During an injection of the dose, the dose button moves in an axial direction to cause the spindle to administer the dose. During resetting of the dose setting mechanism, the spindle is retracted back into the dose setting mechanism. An advantageous resetting mechanism is described.
