An apparatus and method of detecting an interchangeable tip of a handpiece of an ocular surgical system is disclosed. The interchangeable tip of the system includes an irrigation port that receives fluid flowing from an irrigation source and an aspiration port that removes or aspirates fluid and/or materials from the surgical field, in particular a patient's eye, through use of an aspiration source or pump. The method comprises attaching the interchangeable tip to the handpiece, introducing fluid flow into the system and determining the fluid flow rate of fluid flow in the system, determining the pressure of fluid flowing into the interchangeable tip, determining the pressure of fluid flowing out of the interchangeable tip and comparing the flow rate and pressure information to known flow rate and pressure readings of known types of interchangeable tips to determine the type of interchangeable tip being used.

A method of treatment and delivery device for mixed carbon dioxide, carbonic acid, saline and optional active additives for treating head ailments includes delivery of dosage of the treatment at specified flow rates, using a) main housing having a hollow central area containing the dosage; b) a dosage dispenser head located at the distal end of the main housing, and having at least one flow channel for movement of the dosage from the main housing through the dosage dispenser head and to external of the dosage dispenser head; c) a dosage release control component located between the main housing and the dosage dispenser head to permit flow of the dosage through the dosage dispenser head in response to increased pressure against the dosage; and d) a pressure-changing moveable component on the main housing.

A medical device is provided for irrigation of a patient wound site. The device contains a tube having a proximal portion adapted to receive an irrigation solution, a distal portion having a nozzle and an intermediate portion for transporting the solution. The tube has a barrel portion that may be manipulated by a user to position the device relative to the wound site. A distinctive nozzle has a body formed with a distally leading channel presenting a semispherical first spatial conformation and a proximally leading opening formed in the body presenting a second spatial conformation intersecting the semispherical terminus. This geometry, derived from principles of flow mechanics discussed herein, defines what will be described as an “effective diameter” of the nozzle. An assembly and system utilizing the device am also disclosed. The invention utilizes a fluid-isolating durable peristaltic pump for a continuous flow of irrigation solution, along with a single use tube set that embodies the device.

Disclosed is a medical device or system comprising an elongate member having a distal end and a proximal end; an inflow lumen disposed within the elongate member, the inflow lumen having a proximal end, a distal end and a slanting exit opening at the distal end of the inflow lumen; and an outflow lumen also disposed within the elongate member, the outflow lumen having a proximal end, a distal end and a slanting receiving opening at the distal end of the outflow lumen. The disclosed medical device or system further comprises pressure sensors disposed at the distal end of the elongate member. Also disclosed is a method of employing the above disclosed device or variations thereof to remove small stones or small stone fragments from within the body's lumen or internal organ of a subject.

Disclosed is a system for providing artificial saliva. The system can include the mouthpiece, a portable supply unit, and a stationary supply unit. The portable supply unit can be adapted to be carried by a user. The portable supply unit can include a first fluid system, a first interface module, and a first control module. The first fluid system can be adapted to fluidly couple to the mouthpiece.

Ophthalmic surgical devices, systems, and methods for regulating aspiration from a patient's eye are provided. A vacuum pump in fluid communication with an aspiration line provides fluid aspiration from a vitreous chamber of the eye through the aspiration line. A sensor disposed adjacent to or inside the eye determines sensor data relating to an intraocular pressure (IOP). The controller receives the sensor data and regulates the aspiration in response to changes in the TOP, such as by controlling the vacuum pump. The controller may determine whether a fluid infusion to the vitreous chamber through an infusion line is below a maximum infusion level, regulate the infusion in response to the TOP being below a threshold value and the infusion being below the maximum infusion level, and regulate the aspiration in response to the TOP being below the threshold value and the infusion being at or above the maximum infusion level.

Aspects of the present invention provide a method and an apparatus for delivering a solution to a region of a human body, and washing, cleaning, and drying the region. The apparatus include a toilet seat assembly, and a spraying nozzle assembly. The spraying nozzle assembly includes one or more spray nozzle units having one ore more spray nozzle bodies that are retractable and adapted to deliver the solution, a first driving motor being connected to the one or more spray nozzle units and adapted for moving the one ore more spray nozzle bodies in retracting-and-extending motion, and a second driving motor being connected to the one or more spray nozzle unit and adapted for moving the one or more spray nozzle units in three-dimensional circular rotational motion. The one or more spray nozzle units may further include one or more nozzle jet head openings.

Aspects of the present invention provide a method and a remote-controlled system for delivering and applying water, medicines, cleaning solutions to a region of the body that may not otherwise be easily accessible (e.g., to the perianal region). The system is designed to enable the users to relax and enjoy on a bidet seat system that can apply water, medicines, cleaning solutions at a desirable angle that they can control, while the user is in a relatively comfortable and efficacious position for the treatment. The apparatus include a toilet seat assembly, a drying nozzle assembly, a spraying nozzle assembly, and a medicine delivery assembly. A method and apparatus is provided for using and delivering medicine, washing, cleaning, and drying a region of a human body.

In accordance with some configurations, systems and methods for guided removal from an in vivo subject are provided. In some configurations, a method for removing an object is provided. The method comprising, guiding a flexible tube through a passageway of an in vivo subject, wherein the flexible tube comprises at least a first passageway and a second passageway. Positioning a distal end of the first passageway in proximity to the object. Infusing liquid through the second passageway substantially continuously. Removing the object through the first passageway with at least a portion of the liquid while suction is not being provided.

A composition for use in the treatment of fistula, the composition comprising activated carbon.
