## Indications for Use

The ContiDrain™ Catheter is indicated for continuous urine drainage.

## Device Story

ContiDrain™ Catheter is an indwelling urinary catheter for continuous urine drainage. Device functions similarly to a conventional Foley catheter, utilizing a tubular catheter to transport urine from the bladder through the urethra into a drainage bag. Distinguishing features include open-sided flow channels and a retention mechanism adapted from ureteral stent designs. Used in clinical settings by healthcare professionals for insertion and removal. Output is the physical drainage of urine. Benefits include effective bladder drainage and retention. Device is intended for prescription use.

## Clinical Evidence

Feasibility study conducted with 9 adult male patients across three centers. Evaluated insertion/removal ease and retention capability. Results indicated adequate retention when properly secured, satisfactory insertion/removal reported by clinicians, and favorable patient acceptance. Urine drainage was evaluated in one patient and found to be good.

## Technological Characteristics

Indwelling urinary catheter; polyurethane construction; features open-sided flow channels and ureteral stent-style retention mechanism. Bench testing performed using modified Foley and stent draft ASTM methods.

## Regulatory Identification

A urological catheter and accessories is a flexible tubular device that is inserted through the urethra and used to pass fluids to or from the urinary tract. This generic type of device includes radiopaque urological catheters, ureteral catheters, urethral catheters, coudé catheters, balloon retention type catheters, straight catheters, upper urinary tract catheters, double lumen female urethrographic catheters, disposable ureteral catheters, male urethrographic catheters, and urological catheter accessories including ureteral catheter stylets, ureteral catheter adapters, ureteral catheter holders, ureteral catheter stylets, ureteral catheterization trays, and the gastro-urological irrigation tray (for urological use).

## Predicate Devices

- Foley catheter (generic)
- Bard Figure Four Ureteral Stent ([K861478](/device/K861478.md))
- Tower peripheral stent
- Bard Polyurethane (Flexible tip) Ureteral Catheters ([K950300](/device/K950300.md))

DATE SUMMARY PREPARED: 06-19-97

TRADE NAME: ContiDrain™ Catheter & Accessories
COMMON NAME: Urological catheter

SUBSTANTIALLY EQUIVALENT TO: The ContiDrain™ Catheter is substantially equivalent to the Foley catheter indications for use. The ContiDrain™ Catheter is substantially equivalent to the technological characteristics for retention to the Bard Figure Four Ureteral Stent and pigtail ureteral stents (K861478). The ContiDrain™ Catheter employs the same type of open-sided flow channels as are found in the Tower peripheral stent. The ContiDrain™ Catheter is substantially equivalent to the materials of the Bard Polyurethane (Flexible tip) Ureteral Catheters (K950300).

DESCRIPTION OF THE DEVICE: The ContiDrain™ Catheter is an indwelling urinary catheter with the same indication for use and function as a conventional Foley catheter. Like a Foley catheter, the ContiDrain™ Catheter is indicated for continuous urine drainage. Both devices use a tubular catheter to pass urine from the bladder through the urethra and meatus into a urinary drainage bag. Both devices also have a mechanism for retention in the bladder. The ContiDrain™ Catheter has two design features that are different from the conventional Foley catheter. The ContiDrain™ Catheter incorporates two design features found in conventional ureteral stents. These features involve the methods of urine flow and of retention in the bladder.

INDICATIONS FOR USE: The ContiDrain™ Catheter is indicated for continuous urine drainage.

SUPPORTING INFORMATION:

BENCH TESTING: Flow and retention bench testing that has been conducted according to (modified) methods and fixtures described in the Foley and stent (draft) ASTM methods.

CLINICAL EVALUATION: The ContiDrain™ Catheter Feasibility Study protocol has been cleared as a non-significant risk clinical study by the FDA and by three IRB-centers with three investigators. The feasibility study, lasting less than 15 minutes per patient, evaluated how well the healthcare professional can insert and remove the 16 Fr catheter and if the catheter will remain in place during the evaluation period. Nine adult male patients in three centers presenting with either an indwelling Foley catheter or at the urodynamic lab for routine evaluation were enrolled. Data from these centers indicate that retention is adequate when the catheter is properly secured. Furthermore, the healthcare professionals have reported satisfactory insertion and removal, with generally favorable acceptance from the patients. Urine drainage was evaluated in one patient and found to be good.

Dear Dr. Tihon:

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 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. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, 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 Good Manufacturing Practice for Medical Devices: General (GMP) regulation (21 CFR Part 820) and that, through periodic GMP inspections, the Food and Drug Administration (FDA) will verify such assumptions. Failure to comply with the GMP regulation may result in regulatory action. In addition, FDA may publish further announcements concerning your device in the Federal Register.
