A sterile implantable device inserted into the natural cornea to treat presbyopia [age-related hyperopia (far sightedness)] based on aperture reduction. It is typically made of plastic material and is shaped as a thin annulus (disc) formed to fit the curvat...
A standard, non-motorized, diagnostic x-ray beam-limiting device whose aperture size/length/shutter assembly must be manually adjusted in order to match the size of the x-ray beam to the size of the x-ray cassette in use. It includes designs with manual con...
A sterile device designed to be attached to the distal end of a lavage system or kit handpiece to function as an applicator/nozzle that produces an intentional jet, stream or spray of sterile fluid (typically saline) from its aperture to the site of operati...
A device designed to be attached to the distal end of a bone cleaning gas-jet handpiece to function as a nozzle that produces a jet of gas [usually carbon dioxide (CO2)] from its aperture to clean bone during an open surgical orthopaedic procedure. It is av...
A standard, non-motorized, diagnostic x-ray beam-limiting device that has a fixed size opening. It attaches by means of a slot or base plate to a diagnostic x-ray system tube housing and is used to limit the effects of scattered radiation on image quality a...
A metallic (e.g., steel, aluminium alloy) case that houses an x-ray tube to provide appropriate limits for x-ray leakage and adequate insulation to avoid electric risks during a diagnostic x-ray procedure. It includes sheet lead surrounds at appropriate loc...
A lifting device used together with a patient lifting system to provide a support for an incapacitated patient or a person with a disability that is being lifted in a sitting or semi-recumbent position with their body (back, head, arms, buttocks and upper l...
A surgically-invasive device designed to be attached to the distal end of a lavage system or kit handpiece to intraoperatively function as an applicator/nozzle that produces an intentional jet, stream or spray of sterile fluid (typically saline) from its ap...
A non-automated, x-ray beam-limiting device that is a component of a therapeutic x-ray system and whose opening size/length/shutter assembly is fixed. It is used in radiation therapy applications to limit the effects of scattered radiation and to protect th...
A standard, diagnostic x-ray beam-limiting and shaping device with a motorized shutter/length adjustment mechanism that requires the operator to manually adjust the collimator shutters or length of the cone prior to an exposure in order to match the size an...
A standard, diagnostic x-ray beam-limiting and shaping device that includes an automatically controlled motorized shutter mechanism. It is designed to adjust the shutters so that the x-ray beam shape matches the size of the film cassette in the holder and i...
A heavy-duty, hand-held, surgical instrument with specially designed sturdy handles and gripping jaws intended to be used to securely grip around or hold an object during a surgical intervention. It is made of high-grade stainless steel and is designed like...
A sterile optical device intended to be implanted into the posterior chamber of the eye to replace the natural lens (crystalline lens), typically because it has been clouded by a cataract. It consists of an intraocular lens (IOL) containing a small aperture...
A non-motorized, x-ray beam-limiting and shaping device that is a component of a therapeutic x-ray system and that is adjusted manually. It is attached to the x-ray tube housing assembly and adjusts the size and shape of the x-ray beam to match the size and...
A battery-powered hand-held digital electro-optical device designed to capture video or still image data for a variety of medical applications (e.g., ophthalmoscopic, otoscopic and dermatoscopic) using dedicated interchangeable lenses. It typically consists...
An electrically-powered, head-worn, ophthalmic device used for the stereoscopic examination and laser treatment of the eye, particularly the retina. It typically consists of a headband, a built-in light with aperture control for adjustment of the illuminati...
An electrically-powered, hand-held digital electro-optical device designed to capture video or still image data for multiple medical applications (e.g., ophthalmoscopic, otoscopic, and dermatoscopic) using dedicated interchangeable lenses/attachments. It ty...
A mains electricity (AC-powered), head-worn, ophthalmic device used for the stereoscopic examination and laser treatment of the eye, particularly the retina. It typically consists of a headband, a built-in light with aperture control for adjustment of the i...
A material designed for creating a custom-made beam block used to size, shape, or control depth of penetration of a beam of radiation delivered to a patient during radiation therapy treatments, to limit or eliminate exposure to non-target body areas. Beam b...
A motorized, radiation beam-limiting device that is a component of a therapeutic accelerator system and composed of highly-attenuating materials or alloys [e.g., lead (Pb), tungsten (W)] with jaw or leaf positioning functions that are computer-controlled. M...
An electro-optical device that is designed to be attached, either directly or with an adaptor, to a flexible or rigid endoscope to obtain moving-picture documentation of endoscopic findings and procedures. It typically consists of a lightproof chamber with ...
A non-bioabsorbable device designed to be endoscopically implanted into the mucosa/submucosa of the gastrointestinal tract (e.g., stomach, colon) to function as an anchor for a suture used to facilitate healing of post-surgical wounds/defects; the suture ma...
