{0}------------------------------------------------ ## JUN 1 0 1998 K 981477 #### 510(K) SUMMARY #### 1. SUBMITTER: Medical Biopsy, Inc. 10800 Lyndale Avenue South Suite 110 Bloomington, MN 55420 Telephone: 800-714-7788 Contact: Stephen M. Page, Regulatory Consultant Date Prepared: April 23, 1998 #### 2. DEVICE: Classification Name: Instrument, Biopsy Trade Name: Medical Biopsy Automatic Cutting Needle Class II per 21 CFR 876.1075 The Product Code is 78 KNW #### 3. PREDICATE DEVICE: The predicate device used to determine substantial equivalence for the Medical Biopsy Automatic Cutting Needle is the Manan Pro-Mag Automatic Biopsy Device (K914874). #### 4. DEVICE DESCRIPTION: The Medical Biopsy Automatic Cutting Needle is a two-piece design consisting of a cannula and an obturator (stylet). The needles are made of 304 Stainless Steel. Etched markings have been incorporated along the shaft of both the cannula and the obturator, at intervals of 1cm, to guide depth of insertion. The distal end of the stylet is notched for tissue retention. The proximal end of the Automatic Cutting Needle incorporates a plastic fitting for attachment to the "gun" portion of the Biopsy System, which houses, guides and manipulates the Automatic Cutting Needle during use. This "gun" component is sold separately by another company and is not covered within this 510(k) Premarket Notification. {1}------------------------------------------------ When loaded into the "gun", the plastic spacer clip is removed from the end of the Automatic Cutting Needle. The hinged cover of the "gun" is then closed. At this point, the device is cocked, thereby spring-loading the Automatic Cutting Needle within. The distal end of the protruding Automatic Cutting Needle is then inserted into the body towards the target tissue. Once in the proximity of the target, the "gun" is fired and within a fraction of a second, the stylet penetrates the target tissue, which drops into the notch and is subsequently severed by the cannula which moves to recover the entire stylet tip. The gun/needle assembly is then removed from the body and the specimen is removed from the stylet, thus completing the procedure. #### 5. INTENDED USE: The Medical Biopsy Automatic Cutting Needle is intended for use in obtaining samples of tissues or lesions. ### 6. COMPARISON OF CHARACTERISTICS: The Medical Biopsy Automatic Cutting Needle and the currently marketed Manan Pro-Mag Automatic Biopsy Device are very similar in design: - Both devices consist of a two-piece design utilizing a cannula and a stylet. a. - b. The devices have the same Intended Use. - The devices are offered in the same sizes. C. - d. The devices are manufactured from the same material (stainless steel). - Both devices incorporate etched markings to guide depth of insertion. e. റി {2}------------------------------------------------ Image /page/2/Picture/2 description: The image shows the logo for the U.S. Department of Health & Human Services.
