To enhance diffusive mass transfer of solutes, the present hemodialyzer in a cylindrical configuration for hemodialysis comprises a blood compartment having a packed bundle of hollow fibers in a reversibly distensible doughnut configuration on a radial cross-section, and a dialysate compartment having an axial spiral flow converter slidably inserted in a center of the packed bundle of the hollow fibers and an outer circumferential space encircling an outer circumferential layer of the packed bundle of the hollow fibers. The axial spiral flow converter is configured to convert an axial dialysate flow to a centrifugal dialysate flow radially spreading from the center of the packed bundle of the hollow fibers to the outer circumferential space of the hemodialyzer.

A humidifier for delivering humidified gases to a patient includes an inlet, an outlet, a gases flow path extending from the inlet to the outlet, a permeable wall, a liquid reservoir, and a heater. The permeable wall separates the gases flow path from the liquid reservoir. The heater heats liquid stored in the liquid reservoir to form vapour, and the vapour passes through the permeable wall to the gases flow path to humidify gases in the gases flow path. Another inline humidifier for delivering humidified gases to a patient includes an inlet and an outlet and holds a tape made of hydrophilic or hygroscopic material. The tape is pre-soaked with water and can include a heating element. The heating element heats the tape and the stored water to release the stored water as vapour and thereby humidify gases passing through the inline humidifier.

An actuated telescoping system for navigation within a vascular lumen and thrombectomy of a thrombus. The system includes a tubular catheter member having an open distal end defining a catheter lumen, a vacuum source, a rotational drive system, a flexible shaft having a channel coupled to the rotational drive system for rotational movement in response thereto, and an optional guidewire selectively inserted at least partially within the flexible shaft. The flexible shaft is at least partially disposed within the tubular catheter member configured for uncoupled rotational and translational motion therein and to optionally define a corkscrew motion in response to rotational driving force by the drive system that results in formation of hydrodynamic vortices within the catheter lumen. The telescoping system can be capable of reversibly transitioning between navigation and thrombectomy modes by differentially disposing and actuating the components and enable faster, more efficient and simpler removal of thromboembolic material.

An inlet tube of a circulatory support device includes a first end configured to receive incoming blood and a second end coupled to a first end of a blood pump. A lumen extends from the first end to the second end, and a spiral feature is disposed within the lumen and configured to support a spiral flow of the incoming blood.

A vortex catheter thrombolytic system comprises an ultrasonic transducer; and a probe for transmitting a vortex acoustic field as well as a catheter, wherein the catheter is arranged in the probe for transmitting the vortex acoustic field, is connected to the ultrasonic transducer and is provided with a first inner channel and a second inner channel, the first inner channel is used for delivering drugs, and the second inner channel is used for vortex driving. A thrombolytic method comprises: performing an ultrasonic execution step through the vortex catheter thrombolytic system so as to generate an acoustic vortex; executing a focusing step so as to focus a drug delivery carrier to the center of the acoustic vortex; and executing a manipulation step so as to manipulate the drug delivery carrier to a lesion area.

A novel dry powder inhaler. By providing a plurality of capsule chambers (1a, 1b, 1c, 1d) arranged in parallel in a capsule dry powder inhalation device, a medicine dispenser containing active components of a composite product or their mixture separately is provided. The dry powder inhaler has a simple structure and is convenient to operate. In addition, the parameters of air inlet channels and an air outlet channel can be adjusted by means of each capsule chamber (1a, 1b, 1c, 1d) according to the properties of powder of a medicine or a combination, so as to provide an appropriate particle distribution for each active component.

Systems and methods for the treatment of a bodily fluid, for example, using a cartridge that may include a cartridge body configured to retain an adsorptive material and an end segment configured to cover a first end of the cartridge body. The end segment may include a circular face comprising an outwardly truncated conical shape and defining an internal conical space, a cylindrical wall joined to a periphery of the circular face, and an inlet configured to provide fluid connection to a source of the bodily fluid. The inlet may be disposed tangential to the circular face at the cylindrical wall so as to direct bodily fluid entering the cartridge into the internal conical space tangentially so as to decelerate the bodily fluid within the internal conical space prior to contact with the adsorptive material disposed within the cartridge body.

Gas exchange unit comprising an inlet that is acentrically slanted, and a method for producing a gas exchange unit.

A flow component particularly for hemodialysis medical lines includes a duct having a first and a second end tubular connector coaxial to each other and designed to be connected to the line, and an intermediate tubular connector of the female luer type arranged orthogonally to the duct. A hollow elastic element substantially extends along the entire intermediate tubular connector and the body is internally configured so that, in use, the flow along the duct is partly diverted towards the intermediate tubular connector and introduced with a swirling motion along the cavity of the hollow elastic element.
