A drug delivery device capable of forming a medicated mist that reaches the nasal and paranasal sinus cavities contains a puncturing element within its canister. The puncturing element is used in combination with a compartment that contains a filling. The compartment is optionally detachable from an interior of the device or entirely separate from the device. The puncturing element punctures the compartment, releasing the filling into the reservoir of the device to provide a medicated liquid. The device may store any form of medication so long as the medication remains stable. When dry powder forms are desired, the reservoir and/or compartment may be filled with a solution or diluent so as to form the medicated liquid, which may then be dispensed as a mist through the device following the puncturing.

A nasal nebulizer contains a main canister with at least one air exit port and an insert with at least one fluid channel. The fluid channel ends in a common bell housing above a base of the insert, which rests within the canister. The insert and the canister may form one integral unit for single usage, where a cap plugs the air exit port and the fluid channel, allowing for the transport or long-term storage of fluids within the nebulizer device. The insert may include an extension extending out to the canister and a vertical groove may extend down the fluid channel to a hole in the extension, which upon use helps create a vacuum that pulls in deflected fluid for re-use. The nebulizer may also contain a filter surrounding the tube portion near the top of the canister to catch any extraneous matter expelled from the nose during usage.

Nasal irrigator

Intranasal therapy delivery system

A pressurized air supply source for a portable nasal irrigator houses an airflow regulating system, instead of external bulky, heavy components, to power the atomization of fluid for irrigation of nasal passages. The airflow regulating system is made up of a pump, a motor to drive the pump, a filter with an inlet air manifold connected to the pump to eliminate additional tubing within the pressurized air supply source, and an optionally rechargeable battery to drive the motor. An external AC/DC power supply may charge the battery or operate the device when the battery is in a discharged state. A canister for holding fluid attaches on top of the pressurized air supply source and an insert fits that over a fluid channel in the canister to create a venturi effect and draw the fluid out. The pressurized air supply source creates a clinically effective airflow despite its small size.

A method of operating a remote medical navigation system using ultrasound, employs ultrasound imaging from a medical device to supplement or to replace conventional x-ray imaging of the operating region during navigation.

A nasal nebulizer with a main canister for receiving fluid and an insert with a fluid channel includes a contiguous pressurized air supply source. The fluid channel may be a tapered tube overlapping an air exit port in the canister. The fluid channel may also comprise a common bell housing surrounding the air exit port above a base of the insert, which rests within the canister. The insert may include an extension projecting out to the canister and a vertical groove may extend down the fluid channel to a hole in the extension, which upon use helps create a vacuum that pulls in deflected fluid. The main canister includes a convex top surface around the periphery of an opening for a reservoir that receives fluids. The top surface extends downwardly to a generally rectangular opening that connects to the pressurized air supply source.

An implantable medical device and method are provided for determining if a patient is in a substantially horizontal position and delaying a programmed cardioversion/defibrillation shock therapy in response to determining the patient is in a substantially horizontal position. In various embodiments, the shock therapy may be delayed by adjusting tachycardia detection criteria or scheduling the shock therapy after a maximum tachycardia episode duration.

Method and apparatus for controlling arrhythmia detection and treatment based on patient posture

A method and device for nasal irrigation and drug delivery wherein fluid held in a canister is atomized via a compressed air supply to create particles sized for penetration and retention in the nasal cavity under pressure that is able to stent open the soft tissues of the nose to deliver the resultant mist into the whole of the nasal passages without the need for the patient to create an airstream through inhalation. The device consists of a main canister with a reservoir to hold the fluid, two air outlets and an insert that is placed over the air outlets, the insert having at least one outlet that is larger than the holes in the air outlet and allows the fluid to be atomized and injected directly into the nasal cavity.

A connector system for an implantable lead, which includes a header having a lumen for receiving the implantable lead. The lumen defines a mating surface and has an internal diameter larger than the lead to be connected therein. A collar is slidably engageable with the lead. Part of the collar is slidable into the header lumen, and part of the collar is releasably securable to the header such that the lead is retained in the lumen. The part of the collar that is slidable into the header lumen may be tapered. The tapered part of the collar and/or the mating surface may be formed of a compressible material.

A catheter body of a catheter assembly includes a proximal portion, an intermediate portion extending from the proximal portion, a distal portion extending from the intermediate portion, and a locating device including a distal tip extending from the distal portion of the catheter body. The intermediate portion defines a longitudinal axis and the distal portion forms a loop including one or more loop segments formed around a central loop axis. The central loop axis is substantially parallel with the longitudinal axis and the one or more loop segments include at least one ablation electrode coupled thereto and adapted to create a lesion, the lesion electrically isolating a vessel from a chamber for treatment of a cardiac arrhythmia. The distal tip of the locating device is substantially parallel with the central loop axis.

Ablation catheter and method for isolating a pulmonary vein

A catheter assembly and method for treatment of cardiac arrhythmia, for example, atrial fibrillation, by electrically isolating a vessel, such as a pulmonary vein, from a chamber, such as the left atrium. The catheter assembly includes a catheter body and at least one electrode. The catheter body includes a proximal portion, an intermediate portion and a distal portion. The intermediate portion extends from the proximal portion and defines a longitudinal axis. The distal portion extends from the intermediate portion and forms a substantially closed loop transverse to the longitudinal axis. The at least one electrode is disposed along the loop. With this configuration, the loop is axially directed into contact with the chamber wall about the vessel ostium. Upon energization, the electrode ablates a continuous lesion pattern about the vessel ostium, thereby electrically isolating the vessel from the chamber.
