摘要： Embodiments generally relate to propulsion tube units and propulsion devices for progressing instruments along passages, and associated methods of use. For example, the instruments may include, tools, sensors, probes and/or monitoring equipment for medical use (such as endoscopy) or industrial use (such as mining). In some embodiments, the propulsion device may comprise an elongate tube defining a channel configured to accommodate a liquid and a pressure actuator in communication with the channel. The pressure actuator may be configured to selectively adjust a pressure of the liquid in the channel to alternatingly: reduce the pressure to induce cavitation and form gas bubbles in the liquid; and increase the pressure to collapse some or all of the gas bubbles back into the liquid, thereby accelerating at least part of the liquid towards the first end of the tube and transferring momentum to the tube to progress the tube along the passage.

摘要： An improved catheter assembly is provided for advancing a pair of guide wires to a bifurcated vessel in preparation for an interventional procedure. The delivery assembly of the present invention has the novel feature of containing two guide wire lumens in a single cathether to prevent wire wrapping and crossing of the wires. The tracking guide wire lumen and the integrated guide wire lumen run substantially parallel to each other throughout their lengths, and the tracking guide wire lumen and the integrated guide wire lumen do not move apart with respect to each other as the catheter is manipulated. The invention provides for a clip for clipping the wires at their proximal ends outside of the patient, thus helping to prevent wire wrapping, wire crossing, and confusion between wires. The assembly allows for the delivery of two wires to a bifurcation so that the bifurcation is ready for an interventional procedure, such as the implantation of a bifurcated stent.

摘要： An apparatus for steering a guidewire and for connecting the guidewire to an extension guidewire. The apparatus includes a steering device for gripping an exterior of the guidewire, the steering device defining a passageway therein through which the guidewire may pass; and a connecting device for connecting the guidewire to the extension guidewire. The connecting device is configured for mating with the steering device to form an integral unit. The invention further includes a method of inserting a guidewire in a body and connecting the guidewire to an extension guidewire. The method includes the steps of: providing an integral guidewire holder and tool for connecting a guidewire to an extension guidewire; gripping the guidewire with the integral guidewire holder; inserting the guidewire into a body lumen; displacing the integral guidewire holder and tool relative to the guidewire so that the proximal end of the guidewire is located in a slot of the integral guidewire holder and tool; inserting an extension guidewire into the slot of the integral guidewire holder and tool; and connecting the guidewire to the extension guidewire. The method further includes the step of aligning the guidewire and extension guidewire in the slot prior to the connecting step.

摘要： A medical device is provided for use in a nerve block procedure to dispense a numbing agent into a fascial plane of a patient's body that obviates the need for injecting a test dose to. The medical device can include a needle having a wire control mechanism and an echogenic feeler wire that can be viewed using an ultrasound probe. When the needle tip is positioned inside of the patient's body and the user controls the wire control mechanism to cause the feeler wire to move from the non-deployed state to the deployed state, a distal portion of the feeler wire extends out of the needle tip into the patient's body and moves within a region of the patient's body. Viewing the feeler wire on an ultrasound enables one to ascertain whether the needle tip is properly located in the fascial plane without having to inject a test dose.

摘要： Various systems and methods are provided for reducing pressure at an outflow of a duct, such as the thoracic duct or the lymphatic duct, for example, the right lymphatic duct. A catheter system can be configured to be at least partially implanted within a vein of a patient in the vicinity of an outflow port of a duct of the lymphatic system. The catheter system includes first and second selectively deployable restriction members each configured to be activated to at least partially occlude the vein within which the catheter is implanted and to thus restrict fluid within a portion of the vein. The catheter system includes an impeller configured to be driven by a motor to induce a low pressure zone between the restriction members by causing blood to be pumped through the catheter when the restriction members occlude the vein.
