Indications for Use

The CLIMBER - Partially Coated Guide Wire for Endoscopic Use is designed for endoscopic use. The CLIMBER is used for supporting cannulation or insertion into bile duct strictures and pancreatic duct strictures.

Device Story

The CLIMBER is a 450 cm long, 0.035" diameter guide wire used in endoscopic procedures.

Regulatory Classification

Identification

An endoscope and accessories is a device used to provide access, illumination, and allow observation or manipulation of body cavities, hollow organs, and canals. The device consists of various rigid or flexible instruments that are inserted into body spaces and may include an optical system for conveying an image to the user's eye and their accessories may assist in gaining access or increase the versatility and augment the capabilities of the devices. Examples of devices that are within this generic type of device include cleaning accessories for endoscopes, photographic accessories for endoscopes, nonpowered anoscopes, binolcular attachments for endoscopes, pocket battery boxes, flexible or rigid choledochoscopes, colonoscopes, diagnostic cystoscopes, cystourethroscopes, enteroscopes, esophagogastroduodenoscopes, rigid esophagoscopes, fiberoptic illuminators for endoscopes, incandescent endoscope lamps, biliary pancreatoscopes, proctoscopes, resectoscopes, nephroscopes, sigmoidoscopes, ureteroscopes, urethroscopes, endomagnetic retrievers, cytology brushes for endoscopes, and lubricating jelly for transurethral surgical instruments. This section does not apply to endoscopes that have specialized uses in other medical specialty areas and that are covered by classification regulations in other parts of the device classification regulations.

Special Controls

*Classification* —(1)*Class II (special controls).* The device, when it is an endoscope disinfectant basin, which consists solely of a container that holds disinfectant and endoscopes and accessories; an endoscopic magnetic retriever intended for single use; sterile scissors for cystoscope intended for single use; a disposable, non-powered endoscopic grasping/cutting instrument intended for single use; a diagnostic incandescent light source; a fiberoptic photographic light source; a routine fiberoptic light source; an endoscopic sponge carrier; a xenon arc endoscope light source; an endoscope transformer; an LED light source; or a gastroenterology-urology endoscopic guidewire, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 876.9.(2) Class I for the photographic accessories for endoscope, miscellaneous bulb adapter for endoscope, binocular attachment for endoscope, eyepiece attachment for prescription lens, teaching attachment, inflation bulb, measuring device for panendoscope, photographic equipment for physiologic function monitor, special lens instrument for endoscope, smoke removal tube, rechargeable battery box, pocket battery box, bite block for endoscope, and cleaning brush for endoscope. The devices subject to this paragraph (b)(2) are exempt from the premarket notification procedures in subpart E of part 807of this chapter, subject to the limitations in § 876.9.

## ADDITIONAL SAFETY INFORMATION

Sterilization conditions have been validated according to the European Standard, EN 550 (1994); Sterilization of Medical Devices - Validation and Routine Control of Ethylene Oxide Sterilization, to provide a Sterility Assurance Level (SAL) of 10 °.

Ethylene oxide residuals will not exceed the maximum residue limits proposed for Part 821 of Title 21 in the Federal register of June 23, 1978 (or as finalized or amended).

Manufacturing control test methods include: functional, extraction and sterility tests.

Blood contacting materials were tested in accordance with the tests recommended in the FDA General Program Memorandum #G95-1 (5/1/95): Use of International Standard ISO-10993, "Biological Evaluation of Medical Devices Part 1: Evaluation and Testing." [External Communicating Devices. Blood Path Indirect, Limited Duration of Contact (<24 hours).] days). The blood contacting materials were found to be biocompatible.

The expiration dating for the CLIMBER - Partially Coated Guide wire for Endoscopic Use has been established to be 24 months.

#### CONCLUSION

The CLIMBER - Partially Coated Guide Wire for Endoscopic Use submitted in this 510(k) is substantially equivalent in intended use, design, technology/principles of operation, materials and performance to the cleared Terumo 450 cm Guide Wire for G.I. Use (K910722); the Microvasive GEENEN ENDOTORQUE™ Guide Wire; and the WILSON-COOK® TRACER™ WIRE GUIDE Slip-Coat™ Tip. Differences between the devices cited in this section do not raise any new issues of safety or effectiveness.
