Abstract: A thrombectomy catheter system is disclosed which includes a catheter having an exhaust lumen, an infusion lumen and a high pressure tube. The high pressure tube includes a nozzle orifice for forming a high pressure jet of fluid for cutting occlusive material from within a body lumen. The nozzle orifice is positioned to direct the high pressure jet of fluid into the distal end of the exhaust lumen which creates a suctioning effect. The infusion lumen replaces fluid that is removed from the body lumen through the exhaust lumen by a suctioning effect created by the fluid jet.

Abstract: A catheter system includes an elongate catheter having a lumen extending at least partially therethrough, and a leading catheter end segment, a guidewire positionable within the lumen of the catheter, and fastening structure supported adjacent the leading catheter end segment. The guidewire and the catheter are adapted for relative movement. The fastening structure is dimensioned to selectively engage the guidewire to secure the guidewire with respect to the leading catheter end segment such that movement of the guidewire causes deflection of the leading end segment with respect to the longitudinal axis.

Abstract: A compression device controller controls operation of a compression device to inflate at least one inflatable bladder to control forces applied to an arteriovenous fistula of a subject for maturing the arteriovenous fistula.

Abstract: In some examples, a pathogen detection sensor includes an electrical circuit changeable from a first impedance state to a second impedance state in response to a change in the presence of pathogens (e.g., in response to pathogen growth). A substrate of a vascular access includes at least a part of the pathogen detection sensor, such as, for example, part of the electrical circuit. In this way, the pathogen detection sensor may be positionable proximate to a vascular access site in order to detect the presence of pathogens at or near a vascular access site of a patient.

Abstract: A surgical apparatus includes an elongate outer sheath dimensioned for positioning within a body lumen of a patient, a reference member and a removal device. The reference member is adapted for longitudinal movement relative to the elongate outer sheath between a first position at least partially disposed within a longitudinal lumen of the outer sheath and a second position at least partially exposed from the longitudinal lumen. The reference member is adapted to expand when in the second position to generally conform to an internal dimension of the body lumen. The reference member includes a radiopaque material for visualizing the reference member to assist in determining physical characteristics of the body lumen when in the second position. The removal device is adapted for longitudinal movement relative to the reference member, and is configured for disrupting at least a portion of the occlusion within the body lumen.

Abstract: A compression garment includes a plurality of inflatable bladders, a valve body, an inlet, an exhaust, and a rotary valve. The plurality of inflatable bladders is positionable around a limb of a wearer. The manifold defines a plurality of bladder ports, each bladder port in fluid communication with a respective inflatable bladder. The inlet defines an inlet port, and the exhaust defines an exhaust port. The rotary valve is in fluid communication with the inlet port, the exhaust port, and the plurality of bladder ports. Rotation of the valve in a first direction controls fluid communication between the inlet port and the plurality of bladder ports, and rotation of the valve in a second direction, opposite the first direction, controls fluid communication between the exhaust port and the plurality of bladder ports.

Abstract: An indeflator for inflating a therapeutic balloon. A barrel has an interior chamber that receives fluid and an outlet in fluid communication with the interior chamber. A plunger sealingly engages the interior of the barrel. The plunger is selectively movable to dispense fluid through the outlet of the barrel. A coarse inflation control assembly includes a coarse inflation actuator that rotates about a coarse rotational axis to dispense fluid through the barrel at an inverse coarse inflation rate. A fine inflation control assembly includes a fine inflation actuator selectively rotatable about a fine rotational axis to dispense fluid through the outlet at an inverse fine inflation rate. The inverse fine inflation rate is greater than the inverse coarse inflation rate.
