Described here are devices, systems, and methods for cannulating a vessel. Generally, the method may comprise advancing a stent into a first vessel and deploying the stent in the first vessel to hold open one or more valves. This may permit retrograde blood flow through the blood vessel in peripheral vasculature and aid in cannulation of the blood vessel.

The invention relates generally to wearable accessory carriers for mechanical circulatory support systems, and more specifically relates to belts for carrying peripheral components of a VAD. Such wearable accessory carriers may be suitable for carrying and retaining peripheral components of the VAD in a safe, comfortable, and convenient manner. In certain aspects, the invention provides a wearable accessory carrier configured as an elastic belt with several pockets for holding peripheral components. In other aspects, a wearable accessory carrier may be configured as a belt with a magnetic strip configured to carry one or more modular compartments or pockets for holding peripheral components via magnetic attachment. The wearable accessory carriers disclosed herein may be sized to fit around or configured to be worn on a patient's waist, lower or upper torso, thigh, calf, arm, or other limb.

The invention relates to a fluid pump or rotary cutter having at least one first element (9, 10) which can be brought from a transport state into an operating state by changing at least one mechanical property. Such a pump can, for example, be a blood pump for the medical, microinvasive area. The object of achieving a transition between the transport state and the operating state which is as comfortable as possible and in so doing leaving a freedom in the design of the corresponding apparatus, in particular of a pump, which is as large as possible, is achieved using the means of the invention in that the first element at least partly comprises a material (24, 25, 26, 27) or can be filled with a material or material mixture which passes through a chemical reaction, in particular cross-linking, or a crystallization for transition into the operating state.

A method for the fail-safe termination of in vivo drug delivery from an implantable drug delivery system, the method comprising: providing an implantable drug delivery system comprising: a housing having a reservoir for containing a drug, and a port for dispensing the drug to a patient; and an emergency deactivation unit disposed between the reservoir and the port, the emergency deactivation unit comprising a composite structure comprising a biocompatible ferromagnetic mesh open to fluid flow and a hydrophobic meltable material, the hydrophobic meltable material comprising at least one hole therein for enabling a fluid to pass through the hydrophobic meltable material; implanting the implantable drug delivery system within a patient; enabling the drug to flow from the reservoir, through the at least one hole in the hydrophobic meltable material and out the port; and when drug flow is to be terminated, applying a magnetic field to the composite structure, such that a current is induced in the ferromagnetic mesh which heats the ferromagnetic mesh and melts the hydrophobic meltable material, thereby closing the at least one hole in the hydrophobic meltable material and blocking drug delivery to the patient.

The present disclosure relates to aerosol delivery devices and cartridges for aerosol delivery devices. The cartridge comprises a mouthpiece having a proximal end and a distal end, the proximal end of the mouthpiece having an exit portal defined therethrough, a tank defining a proximal end and a closed distal end, the tank being configured to contain a liquid composition that includes a distinctive characteristic, and a heater configured to heat the liquid composition. The distal end of the mouthpiece is configured to engage the proximal end of the tank, and when the cartridge is coupled with the aerosol delivery device at least one feature of the cartridge, or at least one feature of the control device, or at least one feature of both the cartridge and the control device, provides a visual indication of a color associated with the distinctive characteristic.

A method and apparatus for a connection interface between a reservoir or syringe, infusion set tubing, and an infusion pump is provided. The reservoir, a base and a cap are connected to form an integrated unit that is capable of being inserted and secured in an infusion pump housing. The cap and the infusion pump are each provided with at least one sensor or at least one detectable feature, arranged to interact with at least one corresponding detectable feature or sensor on the other of the cap and infusion pump device, to detect one or more of the presence, position or other characteristic of the cap when the cap is aligned or coupled with the infusion pump housing. The detectable feature and sensor may be magnetic, RF, mechanical, optical or any combination.

The present disclosure generally relates to the field of nebulizers for aerosol generation and methods of using same for treating diseases and disorders.

A medical tubing hub can include: a body having a top, bottom, front and back. The body can include a plurality of conduits (e.g., 1, 2, 3, 4, 5, etc.) extending from a conduit top opening at the top to a conduit bottom opening at the bottom. The hub can include an attachment means configured for attaching the body to a patient. In some aspects, the dimension from the top to the bottom of the body (e.g., height) is larger than the dimension from the front to the back of the body (e.g., thickness). In some aspects, the attachment means is a clamp, clip, adhesive on the back, double sided adhesive tape, safety pin, magnet, magnetically responsive material, Velcro, cinch, or other attachment devices. In some aspects, the attachment means is a clamp, magnet, or magnetically responsive material.

An adapter set that is attached to artery-side and vein-side shunt connectors-that are provided on a blood circuit. The adapter set includes: an artery-side adapter that has one end thereof connected to the artery-side shunt connector, has the other end thereof connected to a drainage port that is provided on the outside of the blood circuit, and thereby connects the artery-side shunt connector and the drainage port fluid tight; and a vein-side adapter that has one end thereof connected to the vein-side shunt connector, has the other end thereof connected to a supply port that is provided on the outside of the blood circuit, and thereby connects the vein-side shunt connector and the supply port fluid tight. The structure of the other end of the artery-side adapter and the structure of the other end of the vein-side adapter are different.
