E700 Golden, CO 80401 303-279-7500 Contact Person: Jeff Hill, RA/QA Coordinator This 510(k) summary was prepared on June 11, 2001. #### Device Identification This special 510(k) is for a modification to the Denver Ascites Shunts and Denver PAK: Percutane-I mis opecial 910(x) is to to a speritoneovenous) Shunt. The modification is a change in supplier for the tubing used to fabricate the peritoneal cottagers and the venous catheter of the surgicallythe tubing used to tablied on py the new supplier is very similar in formulation and physical properties to the tabing made of all seen used previously. The shunt with the tubing produced by the new supplier has been found to be substantially equivalent to the legally marketed shunt. #### Intended Use The Denver Ascites Shunts are used to symptomatically treat intractable ascites due to dissemi-I ne Denver Hotelsease, hepatic disease, and other underlying diseases and conditions that cause ascites fluid to build up in the abdominal cavity. ## Device Description The Denver Ascites shunt is made of a fenestrated peritoneal catheter, which collects the ascites r nic Delver I setted on and ich allows flow from the peritoneum to the venous system but no reverse flow; and a venous catheter, which discharges the ascites fluid into the central venous system. The fluid transfer happens automatically when the patient lies down, because of the pressure differential between the peritoneal cavity and the central venous system. The spontaneous rate of transfer can be supplemented by manual pumping of the chamber. Pumping may also help limit buildup of fibrinous debris in the chamber. All components of the shunt are made of silicone rubber. #### Summary of the change The change that was the subject of the special 510(k) was a change in supplier for the tubing that forms the peritoneal catheters of all ascites shunts and the venous catheter of the surgically-placed shunts. The new tubing has been found to be equivalent to the previous tubing by 53 {1}------------------------------------------------ - 1.

E-700 GOLDEN CO 80401 Re: K011862 Denver® Ascites Shunt and Percutaneous Access Kit with Ascites Shunt Dated: June 11, 2001 Received: June 14, 2001 Regulatory Class: II 21 CFR §876.5955/Procode: 78 KPM Dear Ms. Vivian: We have reviewed your Section 510(k) notification of intent to market the device referenced above and we have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28,1976, the enactment date of the Medical Device Amendments or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act). You may, therefore, market the device, subject to the general controls provisions of the Act. However, you are responsible to determine that the medical devices you use as components in the kit have either been determined as substantially equivalent under the premarket notification process (Section 510(k) of the act), or were legally on the market prior to May 28, 1976, the enactment date of the Medical Device Amendments. Please note: If you purchase your device components in bulk (i.e., unfinished) and further process (e.g., sterilize) you must submit a new 510(k) before including these components in your kit. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, and labeling, and prohibitions against misbranding and adulteration. If your device is classified (see above) into either class II (Special Controls) or class III (Premarket Approval) it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 895. A substantially equivalent determination assumes compliance with the Current Good Manufacturing Practice requirements, as set forth in the Quality System Regulation (QS) for Medical Devices: General regulation (21 CFR Part 820) and that, through periodic QS inspections, FDA will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, the Food and Drug Administration (FDA) may publish further announcements concerning your device in the Federal Register. Please note: this response to your premarket notification submission does not affect any obligation you might have under sections 531 through 542 of the Act for devices under the Electronic Product Radiation Control provisions, or other Federal Laws or Regulations. {3}------------------------------------------------ Page 2 - Ms. Bonnie Vivian This letter will allow you to begin marketing your device as described in your 510(k) premarket notification. The FDA finding of substantial equivalence of your device to a legally marketed predicate device results in a classification for your device and thus, permits your device to proceed to the market. If aconed four and since for your device on the labeling regulation (21 CFR Part 801 and additionally 809.10 for in vitro diagnostic devices), please contact the Office of Compliance at (301) 594-4616. Additionally, for questions on the promotion and advertising of your device, please contact the Office of Addrivinally, for questions on the ply please note the regulation entitled, "Misbranding by reference to premarket notification''(21 CFR 807.97).
