An electronic device for producing an aerosol for inhalation by a person includes a mouthpiece, a liquid container, and a mesh assembly having a mesh material and a piezoelectric material. The mesh material is in contact with a liquid of the container. The mesh material is configured to vibrate when the piezoelectric material is actuated, whereby the aerosol is produced. The aerosol may be inhaled through the mouthpiece. The device also includes circuitry and a power supply for actuating the mesh assembly. The mouthpiece, the container, and the mesh assembly are located in-line along a longitudinal axis of the device between opposite longitudinal ends of the device, with the mesh assembly extending between and separating the mouthpiece and the container. The mesh material has a rigidity that is sufficient to prevent oscillations of varying amplitudes during actuation of the piezoelectric material of the mesh assembly for consistently producing the aerosol.

Described are articles formed of a pulp base material comprising fibers, wherein pores are formed between the fibers. A volatile composition with at least one top note component and at least one base note component at least partially fills the pores of the pulp base material. A release rate of the at least one top note component is modulated by the pulp base material, and a release rate of the at least one base note component is enhanced by the pulp base material.

A blood pump includes an impeller assembly housing; and an impeller assembly disposed within the impeller assembly housing. The impeller assembly includes an impeller having a main body, at least one impeller blade extending outwardly therefrom, and a skirt disposed around at least a portion of the main body. At least a portion of the at least one impeller blade is disposed between the main body and an inner surface of the skirt.

A therapeutic device for extended release drug delivery including a refillable reservoir configured to receive a therapeutic agent and having an outlet for delivery of the therapeutic agent to a patient from the reservoir over an extended period. A porous structure is coupled near the outlet of the reservoir, the porous structure formed of sintered material. A barrier layer is coupled to the reservoir on or adjacent a surface of the porous structure such that the therapeutic agent passes through both the porous structure and the barrier layer upon delivery from the reservoir through the outlet. The porous structure is tuned to deliver the therapeutic agent at a diffusion rate and the barrier layer is adapted to block passage of particles having an average particle size within an average particle size range that is outside an average particle size range blocked by the porous structure. Related methods and systems are provided.

A patient interface includes a positioning and stabilising structure having a knitted headgear strap comprising physical properties and/or characteristics that vary across the headgear strap. The entire headgear strap or portions thereof may be knitted as a single piece of material directly into its final shape. The variations in physical properties and/or characteristics may be provided by different knit structures and/or textile compositions.

In endotracheal tube positioning device for providing fixed positioning and slidable repositioning of a patient's endotracheal tube within a patient's oral cavity includes a neckband, slide track member, a bracket for securement of the tube, and a flexible overlay strip. The slide track member, bracket, and overlay strip are affixed to the neckband. The device permits slidable side-to-side adjustment of the secured endotracheal tube within the patient's oral cavity without having to remove or detach the neckband from around the patient's neck. The bracket can be secured to the endotracheal tube by with an adhesive backed tape or a tube securement strap having engagement elements mating with an adhesive backed patch adhered to the endotracheal tube.

An apparatus for providing a pressurised flow of breathable gas to the airways of a patient includes a pivotable outlet port structured and arranged to connect to an air delivery tube configured to pass the pressurised flow of breathable gas to a patient interface. The pivotable outlet port is able to pivot about at least one axis.

The catheter canal is a medical device. The catheter canal is configured for use with a guiding catheter or guide sheath. The catheter canal forms a canal that controls and eliminates potentially undesirable movement of a catheter, wire, stent, balloon or any other over the wire instrument as it is inserted into a patient. The catheter canal includes a guiding structure, a plurality of flexible structures, and an adhesive structure. The plurality of flexible structures and the adhesive structure attaches to the guiding structure. The plurality of flexible structures form a framework that creates the canal that controls and limits potentially undesirable movement of the catheter, wire, stent, balloon or any other over the wire instrument.

Systems, devices, and methods discussed herein can be for validating a position of a wirelessly powered electrostimulation device while the device is implanted in body tissue. A method can include situating the electrostimulation device in tissue and before an affixation mechanism of the electrostimulation device is deployed to maintain an implanted position of the electrostimulation device, and while electrodes of the device are in contact with the tissue, performing electrical testing of the electrostimulation device to determine whether the electrostimulation from the electrostimulation device evokes a specified response from the body that contains the tissue.

Provided is a blood component sampling cassette which can be efficiently manufactured at low cost compared to a conventional cassette, a method for manufacturing the blood component sampling cassette, a blood sampling circuit set and a blood component sampling system. The blood component sampling cassette includes a cassette main body having a plurality of flow paths including an introduction line, a blood component transfer line and a retransfusion line. The cassette main body includes a first sheet and a second sheet which are formed of a soft material compatible with autoclave sterilization. The first sheet and the second sheet are overlaid in a thickness direction and bonded to each other. A plurality of flow paths is formed between the first sheet and the second sheet.
