A fluid delivery device comprising a fluid reservoir; a transcutaneous access tool fluidly coupled to the fluid reservoir, the transcutaneous access tool including a needle or a trocar; and a transcutaneous access tool insertion mechanism for deploying the transcutaneous access tool, wherein the insertion mechanism is configured to insert and retract the needle/trocar in a single, uninterrupted motion.

A fluid delivery device comprising a fluid reservoir; a transcutaneous access tool fluidly coupled to the fluid reservoir; and a drive mechanism for driving fluid from the reservoir, the drive mechanism comprising a plunger received in the reservoir; a leadscrew extending from the plunger; a nut threadably engaged with the leadscrew; a drive wheel; and a clutch mechanism coupled to the drive wheel, wherein the clutch mechanism is configured to allow the nut to pass through when disengaged and is configured to grip the nut when engaged such that the drive wheel rotates the nut to advance the drive rod and the plunger into the reservoir.

A valve is disclosed that has a body with an inlet, an outlet, and a needleless access port coupled to the body. The access port has an interior space and is configured to be actuated by a needleless connector. The inlet is selectively coupled to the outlet through the interior space such that fluid entering the inlet entirely flows through the interior space to the outlet.

Apparatus and methods for providing controlled pressure-flow pulses which purge a catheter system with turbulent flow flushing. Accomplishment of such controlled pressure-flow pulses is provided by a variety of inventive devices including a special plunger rod for a conventional syringe, other interactive parts for conventional syringes, an in-line catheter attachable device which automatically generates the controlled pressure-flow pulses and also single pulse, digitally operated devices.

A percutaneous transluminal angioplasty (PTA) catheter may be configured to perform vein expansion and occlusion. A infusion port (132) located proximal to the occlusion feature (162) can be used to inject contract enhancement agent as well as other substances. The catheter can be used especially advantageously in vascular regions associated with hemodialysis access.

Provided is a method for delivering a medical fluid. The method includes delivering a fluid volume, which includes contrast and/or a flush fluid, at a preselected total volumetric flowrate during a first duration of a fluid delivery procedure. The amount of the contrast agent and the flush fluid in the fluid volume can be controllably varied during the first duration of the fluid delivery procedure so as to substantially maintain a preselected total volumetric flowrate throughout the first duration of the fluid delivery procedure. Also provided is a fluid delivery system capable of performing this method.

A fluid delivery system includes a pressurizing mechanism. The pressurizing mechanism includes: a substantially cylindrical body having a movable member positioned therein that divides the body into a first chamber and a second chamber; a plunger rod connected to a first side of the movable member and extending through a substantially closed first end of the body; and an elongated member connected to a second side of the movable member and extending through a substantially closed second end of the body. The plunger rod configured to operatively engage a fluid container. Fluid is dispensed from the fluid container by forming a vacuum within at least the first chamber by moving the movable member toward the second end of the body, allowing atmospheric pressure to enter the second chamber, and actuating the pressurizing mechanism to cause the moving member to move towards the first end of the body.

A pump for delivering fluid from a reservoir to a patient includes at least one pumping syringe having a barrel and a plunger movable through the barrel and at least one actuator for moving the plunger through the barrel to draw the fluid from the reservoir into the barrel and to expel the fluid from the barrel towards the patient. The pump also includes at least one inflow valve between the reservoir and the barrel of the at least one pumping syringe that opens when the plunger moves to aspirate the fluid from the reservoir into the barrel; and at least one outflow valve between the barrel of the at least one pumping syringe and the patient that opens when the plunger moves to expel the fluid from the barrel of the at least one pumping syringe towards the patient.

A gas removal apparatus and a method for removing gas bubbles from at least a part of a medical device disposed in an interior chamber of a gas removal apparatus. The gas removal apparatus includes an interior chamber, a filling surface, a first opening arranged at an end of the filling surface and that provides a first path into the interior chamber, and a second opening that provides a second path into the interior chamber. When the apparatus is arranged in a liquid receiving position, at least a portion of the at least the part of the medical device is disposed above an uppermost surface of liquid in the interior chamber, and when the apparatus is arranged in another position different from the liquid receiving position, the entirety of the at least the part of the medical device is disposed below an uppermost surface of liquid in the interior chamber.

A communication device for near field communication (NFC) with a catheter includes an NFC coil and a communication circuit connected thereto and is configured for bidirectional near-field communication with the catheter. The device includes a rechargeable energy storage device, and an electric charging coil connected to a charging circuit for charging the energy storage device. A housing surrounds the NFC coil, the communication circuit, the energy storage device, the charging coil and the charging circuit. The housing is configured to be releasably secured to the catheter for near-field communication with the catheter. The housing is preferably in the form of a catheter handle. A system includes a docking station configured to communicate with and dock the communication device. The system can include a computer configured to communicate with the docking station.
