A portable electronic fluid dispensing system can provide pre-filled, pre-primed IV bag assemblies comprising therapeutic fluids. The same fluid line and connector in the IV bag assembly can be used to fill the IV bag as is used to withdraw fluid from the IV bag and infuse such fluid into the patient. The connection points along the IV assembly, such as the connection between the IV bag and a drip chamber, or between an IV bag and tubing, or between a drip chamber and tubing, or between tubing and a closeable, resealable connector, can each be resistant to disconnection by a user. The healthcare practitioner at the patient care site is not required to attach any of these components to each other, and the healthcare practitioner at the patient care site is not required to introduce a spike into a spike port on the IV bag.

A drip chamber assembly that functions irrespective of its orientation and in the presence of increased internal pressure is provided.

A patient support apparatus having a support structure with a primary support surface for a patient, and an extension manually movable by a user relative to the support structure from a stowed position to an extended position so that the extension provides auxiliary support for the patient in the extended position. A locking device is operable to releasably hold the extension relative to the support structure in the stowed position and the extended position. A release mechanism is operable to manipulate the locking device to release the extension for movement relative to the support structure, and is movable with the extension from the stowed position to the extended position.

According to aspects disclosed herein, an infusion lead assembly may include a housing including a needle receptacle, a housing lumen, a pin receptacle, and a housing conductive trace; a connector including an connector needle, an internal lumen, a metal pin, and a connector conductive trace, and an infusion lead body including an infusion lumen, an exit port, an internal wire, and a distal electrode. The infusion lead assembly may form an electrical path to transmit electrical signals across the connector conductive trace, the metal pin, the housing conductive trace, the internal wire, and the distal electrode. The infusion lead assembly may form a fluid path to transmit fluid across the internal lumen, the connector needle, the infusion lumen, and the exit port.

The present disclosure provides a coupling system for coupling a medical accessory to an accessory support is provided. The present disclosure also provides a system for powering a medical accessory with an accessory support.

An irrigated high density electrode catheter can comprise a catheter shaft. The catheter shaft can include a proximal end and a distal end and can define a catheter shaft longitudinal axis. A flexible tip portion can be located adjacent to the distal end of the catheter shaft. An irrigated coupler can be disposed on the distal end of the catheter shaft and can be configured to discharge fluid over the flexible tip portion.

A drug delivery device including a reservoir configured to contain a fluid to be delivered by advancing a piston in the reservoir at an advancement speed defining a delivery rate for the medicament. The device further includes an electric motor configured to drive the delivery mechanism by rotation to advance the piston at the advancement speed. The device further includes a control unit that controls a rotational speed and an on state/off state of the electric motor. The control unit determines rotational speed of the electric motor based on a back-electromagnetic force signal provided from the electric motor while operating in a monitoring mode. The control unit controls the rotational speed of the electric motor such that a back-emf signal can be detected in the monitoring mode. The control unit modulates the on state/off state of the electric motor to adjust the delivery rate of the medicament.

A method may include positioning a distal portion of a neuromodulation catheter in a first renal vessel of a patient. The distal portion may include a plurality of therapeutic elements arranged around a perimeter of the distal portion. The method also may include imaging the distal portion to visualize positions of the plurality of therapeutic elements; manipulating the distal portion so that at least one therapeutic element is oriented toward a second renal vessel adjacent the first renal vessel; deploying the at least one therapeutic element to extend at least partially through the wall of the first renal vessel such that the at least therapeutic element extends toward the second renal vessel; and delivering a chemical agent through the plurality of therapeutic elements to modulate activity of at least one renal nerve adjacent to the first renal vessel and at least one renal nerve adjacent to the second renal vessel.

A method for performing a medical procedure requiring effective, reliable and foolproof delivery of controlled amounts of a medical grade gas to a patient includes providing a compressed gas cylinder having a weight with medical grade gas sealed therein of at least twelve grams and not greater than fifty grams. The method also includes connecting the compressed gas cylinder to an integrated compressed gas unit including a regulator valve assembly positioned between an outlet port and an inlet port, wherein the regulator valve assembly includes a press button actuator and regulator adjustment dial. A flow control system is secured to the compressed gas unit and the medical grade gas is delivered in precisely controlled amounts by actuating the compressed gas unit and operating the flow control system to deliver the medical grade gas to vasculature of the patient.

A fill adapter system for an infusion pump assembly. The system includes a reusable fill adapter base, the base including a volume control mechanism to adjust an available fill volume of a reservoir of the infusion pump assembly and a pump mechanism configured to pump air into a fluid vial. The system also includes a vial adapter assembly including a first needle configured to penetrate a septum of the fluid vial for fluidly coupling the pump mechanism to the fluid vial and a second needle having a first end configured to penetrate the septum of the fluid vial and a second end configured to penetrate a septum of the reservoir of the infusion pump assembly to allow transfer of fluid from the fluid vial to the reservoir of the infusion pump assembly in response to air being pumped into the fluid vial and a needle carriage adapted to carry the first needle and the second needle, wherein the needle carriage slidably attached to the interior of the vial adapter assembly, wherein the needle carriage adapted to slide from a vial end of the vial adapter to a receptacle end of the vial adapter.
