Balloon urethral dilator catheters are used for transluminal dilation of ureteral strictures or ureteral dilation prior to ureteroscopy or stone manipulation. A special pin-vise handle is included to stabilize the wire guide during introduction.

Balloon urethral dilator sets are used for ureteral dilation prior to ureteral stone manipulation or ureteroscopy, and dilating the intramural ureter.

Bandage contact lenses are frequently used in the setting of such LASIK postoperative complications as large epithelial defects, poor flap adherence, flap displacement, and free caps. It promotes corneal epithelial healing and can improve patient comfort. It also reduces flap movement secondary to eyelid excursions, thus theoretically reducing the development of flap wrinkles, flap displacement, and flap loss. It also introduces a potential for flap slippage at the time of removal, and a potential for tight lens syndrome.

Bandage scissors have a small foot on one of the blade tips, which allows them to be placed directly against a patient's skin when cutting bandages. These are mostly used to cut through medical gauze, custom-fit bandages, and through bandages.

Soft lenses are often used in the treatment and management of non-refractive disorders of the eye. A bandage contact lens protects an injured or diseased cornea from the constant rubbing of blinking eyelids thereby allowing it to heal. These are used in the treatment of conditions including bullous keratopathy, dry eyes, corneal ulcers and erosion, keratitis, corneal edema, descemetocele, corneal ectasis, anterior corneal dystrophy, and neurotrophic keratoconjunctivitis.

Bandage is a piece of material that is used either to support a medical device such as a dressing or splint, or on its own to provide support to the body. These are available in a wide range of types, from generic cloth strips, to specialised shaped bandages designed for a specific limb or part of the body. It is often used to mean a dressing, which is used directly on a wound, whereas a bandage is technically only used to support a dressing, and not directly on a wound.

Plastic adhesive bandages are ideal for minor cuts, abrasions and puncture wounds. It is made of a pliable vinyl; each bandage is ventilated to aid in the natural healing process.

Bar Electrodes are composed of pieces of different lengths joined together with dowels of the same substance as the electrode is made of. The bar electrodes are used to detect if water is entering the pump unit of the water-pump apparatus. Bar electrodes are non-ferrous and consist of two tin electrodes placed 30mm apart in a watertight acrylic bar.
