Injection needles designed to penetrate into the urethra and/or the urinary bladder neck or wall during cystoscopic procedures. These devices typically consist of 23-gauge needles, 35 to 45 cm (14 to 18 inches) in length, with appropriate 7 to 8 mm tips to minimize cutting and/or lesion of adjacent tissues and nerves. Cystoscopic injection needles are frequently intended to administer filling materials such as collagen to treat stress urinary incontinence; they are also used to inject Teflon and/or other polymers in the treatment of vesicoureteral reflux.
