Abstract: A resettable drive mechanism for a medication delivery device comprising a housing and a drive member rotatable in a second direction for delivering a dose. A piston rod driven distally when a drive member rotates in the second direction. A stop member prevents rotation of the drive member in a first direction opposite the second direction, when the stop member engages the drive member. A clutch member is movable between a delivery and reset position. When the clutch member is in the delivery position, the stop member and the drive member engage and the drive member is prevented from rotating in the first direction. When the clutch member is in the reset position, the drive member and the stop member disengage. The drive member is rotatable in the first direction.

Abstract: A fistula catheter which allows a supply tube to be easily connected to a body-external fixing member positioned on the body surface side, and which is only slightly invasive for a patient is provided. The fistula catheter 10 includes a tube body 11 which is inserted into a fistula formed in the abdominal wall and the wall of the alimentary canal; a body-external fixing part 12 which is linked to one end of the tube body 11 and positioned on the abdominal wall surface side of the fistula; and a body-internal fixing part 13 which is linked to the other end of the tube body 11 and positioned inside the wall of the alimentary canal. The body-internal fixing part 13, and the fistula catheter has a flow path allowing fluid to flow through the body-external and body-internal fixing members. The body-external fixing part 12 includes a flexible tube 1 and is connected substantially at right-angles to the axial direction of the tube body 11.

Abstract: An auto-injector comprising a housing arranged to contain a slidably arranged syringe. The housing having a distal end and a proximal end with an orifice. Spring means is capable of, upon activation: pushing the needle into an advanced position and into an injection site, operating the syringe to inject a dose of medicament, and retracting the syringe. Activating means locks the spring means in a pressurized state prior to manual operation and capable of releasing the spring means for injection. The spring means is a compression spring grounded distally in the housing and proximally bearing against a thrust tube arranged to transmit load from the spring means via a plunger to the syringe and/or the stopper. A tubular syringe carrier is arranged for holding the syringe and supporting it at a proximal end, the syringe and the syringe carrier arranged for joint axial translation.

Abstract: The present invention relates to a medicament delivery device that is reliable, safe and intuitive to use and configured to prevent a subsequent dose from being administered before a previously initialized dose has been fully delivered. This is accomplished by mechanically interacting structures arranged as an interface between a lockable delivery button and a release member.

Abstract: A mechanical patient-controlled analgesia device for injecting medicine into a patient's IV, includes an IV reservoir and a syringe communicated to the IV reservoir and having a syringe plunger. A mechanical biasing element is provided for exerting bias on the syringe plunger in a first syringe-filling direction to draw medicine from the IV reservoir into the syringe. An injection plunger is operable by the patient to move the syringe plunger in a second injection direction against the bias to inject the medicine in the syringe into a patient's IV. The injection plunger is movable independently of the syringe plunger and is engaged with but unconnected to the syringe plunger when the patient moves the injection plunger to inject the medicine. The patient can inject only a calibrated amount of medicine drawn into the syringe as determined by calibration of the biasing element and a metering element for a given viscosity of the medication.

Abstract: A protective cap coupled to a syringe having a needle attached thereto. The protective cap may be pivoted to a position in alignment with the needle so that the protective cap substantially envelops the needle. A plug may be inserted into the cap to envelop or capture the needle within a hollow body of the plug to secure at least a tip of the needle.

Abstract: A drive member and a rotation member are rotatable with respect to a housing. A stop member is rotationally locked with the housing. Clutches unidirectionally rotationally engage the drive member with the rotation member and with the stop member when a unit is attached to the housing. A separating member is disposed between the rotation member and the stop member. The separating member causes a separation of the rotation member, the drive member and the stop member when the unit is removed. A coupling feature of the separating member is provided to engage the unit and to move the separating member when the unit is being attached to the housing or is being removed.

Abstract: An irrigation sleeve for a phacoemulsification needle is constructed with a non-uniform distribution of mass. When the sleeve is used with torsional phacoemulsification apparatus the sleeve adds to the eccentric motion of the needle, adding efficiency to the phacoemulsification process. In one embodiment, weights are implanted in the sleeve. In another embodiment the sleeve is molded with concentrations of sleeve material at selected locations in the sleeve.

Abstract: A device (10) for at least partially inserting a needle (16) into the body of a patient is disclosed. The device (10) comprises a connector adapted for attachment to a needle (16), and a guard member (18) having a guide surface adapted to rest against a surface of the skin. The connector is adapted to set an attached needle (16) with a fixed position relative to the guard member (18), such that movement of the guide surface along the surface of the skin at least partially inserts the needle (16) into the body.

Abstract: Valves, valved fluid transfer devices and ambulatory infusion devices including the same. The valves may include a valve seat and a valve element, and be configured such that one of the valve seat and the valve element includes a main portion and a seal portion that is less tacky than the main portion and is in contact with the other of the valve seat and the valve element when the valve element is in a closed position.
