A protective dental needle includes a sheath having a cylindrical body with a channel along the cylindrical body. A needle assembly includes a hypodermic needle extending through a hub. The needle assembly is retained within the sheath and movable within the sheath between a retracted position and an extended position. A needle cap is positioned external to the sheath. The needle cap includes a plurality of longitudinal ribs that extend from an interior surface of the needle cap.

A method of localized delivery of a therapeutic and/or diagnostic agent to nasal tissue or cavities includes inserting a catheter into a nasal cavity, the catheter having an outer balloon with at least one opening therethrough and an inner surface, and an inner balloon disposed in the outer balloon and at least partially enclosing an inflation chamber and having an outer surface defining a space between the outer surface of the inner balloon and the inner surface of the outer balloon, supplying the agent to the space between the outer surface of the inner balloon and the inner surface of the outer balloon via a first lumen of the catheter, and inflating the inner balloon by supplying fluid to the inflation chamber via a second lumen of the catheter to urge the agent out of the opening in the wall of the outer balloon and into nasal tissue.

Devices and systems for delivering an aerosolized reperfusion-injury-modifying drug (RIMD) to a patient are described. In an embodiment, the devices include an RIMD; an aerosolizer in fluid communication with the RIMD configured to aerosolize the RIMD to provide an RIMD aerosol; and an exit port configured to direct the RIMD aerosol for receipt by the patient. In an embodiment, the systems include a ventilator configured to generate airflow and coupled to the exit port. Methods for delivering an aerosol comprising an RIMD to a patient are also described. In an embodiment, the methods include aerosolizing an RIMD to provide an RIMD aerosol comprising RIMD droplets; and introducing the RIMD aerosol into an inhalation airflow of the patient.

Disclosed herein is a dental anesthetic delivery device. The dental anesthetic delivery device may comprise a handle and a body having a trough with a concave, horseshoe-shaped inner cavity. The inner cavity, which may be positioned over and around the area of a painful tooth, may further provide a soft or otherwise non-irritating interior surface which may comprise materials such as mesh, gauze, padding, or similar. The interior surface may act as a carrier of and delivery platform for various dental anesthetic substances. The dental anesthetic delivery device may incorporate a temperature modulation system that allows for the delivery of heat or cold to the affected area.

The present disclosure relates to administration of fluid medication, in particular medication and dosing regimen for management of pain, more specifically to an anesthetic and dosing regimen for anesthetic for perioperative pain management and/or for palliative care. The present disclosure relates further to a medication pump and a method for delivering medication using the medication pump.

A drug delivery and monitoring device comprising a nerve stimulating element configured to deliver an electric stimulus, a recording element configured to detect a compound action potential, and a drug-delivery element.

Embodiments of the invention provide a system and method for accessing an internal body region using a catheter. The catheter includes a catheter body and a medication lumen positioned within the catheter body for delivering medication to the internal body region. An inflation lumen is positioned within the catheter body. A balloon is in fluid communication with the inflation lumen, and the balloon is configured to move between a collapsed position and an expanded position as fluid enters the balloon through the inflation lumen. An anchor covers at least a portion of the balloon on an outer surface of the catheter body and includes a movable section with a first retracted position and a second deployed position. Upon inflation of the balloon, the movable section of the anchor moves radially outward from the first contracted position to the second deployed position to secure the catheter in the internal body region.

The present invention relates to the titration and delivery of anesthetic and sedative medications to a subject. Further, the present invention relates to a device and methods for titrating and delivering such medications in a semi-automated or fully automated manner and which can be monitoring and controlled remotely. Even still further, the present invention relates to such a device that can perform the titration and delivery of medication in a manner that minimalizes occlusion and prevents back flow of the medication. More particularly, the present invention relates to a device for titration and delivery of medication using a non-concentric pumping mechanism that gradual or progressively increases and decreases occlusion in the medication delivery line within the pump to minimize and/or prevent sudden formation and release of occlusion in order to provide more steady and continuous flow of the medication through the device to the subject.
