GAG · Stapler, Surgical

General Hospital · 21 CFR 878.4740 · Class 2

Overview

Identification

Surgical stapler for external use: A specialized prescription device used to deliver compatible staples to skin during surgery. Surgical stapler for internal use: A specialized prescription device used to deliver compatible staples to internal tissues during surgery for resection, transection, and creating anastomoses.

Classification Rationale

Surgical stapler for external use: Class I (general controls). The device is exempt from the premarket notification procedures in subpart E of part 807 of this chapter, subject to the limitations in § 878.9. Surgical stapler for internal use: Class II (special controls).

Special Controls

*Classification.* Class II (special controls). The special controls for this device are:(i) Performance testing must demonstrate that the stapler, when used with compatible staples, performs as intended under anticipated conditions of use. Performance testing must include the following: (A) Evaluation of staple formation characteristics in the maximum and minimum tissue thicknesses for each staple type; (B) For manual staplers only, measurement of the worst-case deployment pressures on stapler firing force; (C) Measurement of staple line strength; (D) Confirmation of staple line integrity; and (E) In vivo confirmation of staple line hemostasis. (ii) For powered staplers only, appropriate analysis/testing must demonstrate the electromagnetic compatibility and electrical, thermal, and mechanical safety of the device. (iii) For powered staplers only, appropriate software verification, validation, and hazard analysis must be performed. (iv) Human factors testing must demonstrate that the clinician can correctly select and safely use the device, as identified in the labeling, based on reading the directions for use. (v) The elements of the device that may contact the patient must be demonstrated to be biocompatible. (vi) Performance data must demonstrate the sterility of the device. (vii) Validation of cleaning and sterilization instructions must demonstrate that any reusable device components can be safely and effectively reprocessed per the recommended cleaning and sterilization protocol in the labeling. (viii) Performance data must support the shelf life of the device by demonstrating continued device functionality, sterility, and package integrity over the identified shelf life. (ix) Labeling of the device must include the following: (A) Unless data demonstrates the safety of doing so, contraindications must be identified regarding use of the device on tissues for which the risk of stapling outweighs any reasonably foreseeable benefit due to known complications, including the stapling of tissues that are necrotic, friable, or have altered integrity. (B) Unless available information demonstrates that the specific warnings do not apply, the labeling must provide appropriate warnings regarding how to avoid known hazards associated with device use including: ( *1* ) Avoidance of use of the stapler to staple tissue outside of the labeled limits for maximum and minimum tissue thickness;( *2* ) Avoidance of obstructions to the creation of the staple line and the unintended stapling of other anatomic structures;( *3* ) Avoidance of clamping and unclamping of delicate tissue structures to prevent tissue damage;( *4* ) Avoidance of use of the stapler on the aorta;( *5* ) Establishing proximal control of blood vessels prior to stapling where practical and methods of blood vessel control in the event of stapler failure;( *6* ) Ensuring stapler compatibility with staples; and( *7* ) Risks specifically associated with the crossing of staple lines.(C) Specific user instructions for proper device use including measures associated with the prevention of device malfunction, and evaluation of the appropriateness of the target tissue for stapling. (D) List of staples with which the stapler has been demonstrated to be compatible. (E) Identification of key performance parameters and technical characteristics of the stapler and the compatible staples needed for safe use of the device. (F) Information regarding tissues on which the stapler is intended to be used. (G) Identification of safety mechanisms of the stapler. (H) Validated methods and instructions for reprocessing of any reusable device components. (I) An expiration date/shelf life. (x) Package labels must include critical information and technical characteristics necessary for proper device selection.
