The device description and performance studies focus on mechanical components and bench testing, with no mention of AI, ML, image processing, or data-driven performance metrics.
No.
The device is used to remove foreign bodies, which is an intervention rather than a therapeutic treatment for a disease or condition.
No
The device is described as an "extractor" for removing foreign bodies, which is a therapeutic function, not a diagnostic one. While it operates "under direct vision," this is for guidance during the removal procedure, not for identifying pathologies or making a diagnosis.
No
The device description explicitly states it is made of stainless steel and lists multiple physical components (obturator, sheath, grasper, etc.), indicating it is a hardware device, not software-only.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use is the "removal of a foreign body from the bladder under direct vision." This is a therapeutic procedure performed directly on a patient's body, not a test performed on a sample taken from the body.
- Device Description: The device is a surgical instrument designed for grasping and removing objects from the bladder. It does not involve the analysis of biological samples.
- Lack of IVD Characteristics: There is no mention of analyzing blood, urine, tissue, or any other biological sample. The device's function is purely mechanical for removal.
IVD devices are used to examine specimens derived from the human body to provide information for diagnosis, monitoring, or screening. This device does not fit that description.

Device Description
The AMS Foreign Body Extractor is made of stainless steel and consists of an obturator, sheath, grasper, seals, handle, security clip, telescope stabilizers and ACMI adaptor ring. The AMS Foreign Body Extractor Accessory Kit contains replacement security clip, telescope stabilizers, ACMI adaptor ring, and seals. To facilitate insertion into the urethra and bladder, the obturator is placed inside the sheath. Once inside the bladder, the obturator is removed and the grasper is placed within the lumen of the sheath. The handle is then attached and the telescope inserted into the sheath. The grasping jaws are operated by moving the handle to open and close the grasping jaws to capture and remove the foreign body.

DEVICE DESCRIPTION IV.
The AMS Foreign Body Extractor is made of stainless steel and consists of an obturator, sheath, grasper, seals, handle, security clip, telescope stabilizers and ACMI adaptor ring. The AMS Foreign Body Extractor Accessory Kit contains replacement security clip, telescope stabilizers, ACMI adaptor ring, and seals.

V. INDICATION FOR USE
The AMS Foreign Body Extractor is intended for use in the removal of a foreign body from the bladder under direct vision.

COMPARISON TO PREDICATE DEVICE VI.
The AMS Foreign Body Extractor is substantially equivalent to the Richard Wolf 8393 Modular Biopsy Forceps and the Richard Wolf series 8962 Rigid Forceps with Alligator Jaws which are in commercial distribution.
a. Intended Use
The AMS Foreign Body Extractor is intended to remove a foreign body from the bladder under direct vision. The Richard Wolf 8393 series modular biopsy forceps are used for removal of tissue for biopsy. The Richard Wolf Rigid Forceps with alligator jaws are intended for the percutaneous removal of kidney stones.
Principles of Operation b.
The AMS Foreign Body Extractor utilizes a grasper operated by handle grips to grasp foreign bodies, retract within a sheath and subsequently remove from the bladder. The Richard Wolf series 8393 modular forceps similarly utilize a grasper which is operated by handle grips to transurethrally grasp and subsequently remove material. The Richard Wolf 8962 Rigid forceps with alligator jaws utilize a similar grasper which is manipulated by handle grips to grasp and remove stones from the kidneys.
Device Performance C.
The AMS Foreign Body Extractor is manufactured primarily from stainless steel, which is widely used in the medical device industry. The material has previously undergone biocompatibility testing.
All components are verified to ensure that only those meeting all parameters are released for sale.
The Richard Wolf series 8393 modular forceps and the Richard Wolf rigid forceps with alligator jaws both utilize stainless steel in the functional components of the tools.
d. Bench Testing
American Medical Systems has provided descriptive data on the test plan and test results for the Foreign Body Extractor. These data support that the function and characteristics of the device are suitable for its intended use.
In summary, American Medical Systems has provided information within the 510(k) Premarket Notification to indicate that the Foreign Body Extractor is safe and effective for its intended use in the removal of foreign bodies from the bladder. Additionally, the Foreign Body Extractor has been shown to be comparable in terms of intended use and technological characteristics to biopsy forceps currently in commercial distribution.
