Abstract
Abstract The apparatus is a sheath which includes a substantially puncture-proof cap and a flexible tubular extension for covering a portion of the cable which extends between the ultrasound scanhead and the ultrasound apparatus. The apparatus is sterilizable to prevent contamination of the patient during procedures, such as a biopsy, which may be conducted under the guidance of ultrasound.
