The device description and performance studies focus on mechanical properties and biocompatibility, with no mention of AI/ML components or data processing.
No
The device is a surgical instrument used to temporarily occlude blood vessels during surgery, not to treat or permanently alter a condition.
No
Explanation: The device, PICOCLAMP, is described as a surgical instrument used to temporarily occlude blood vessels during surgery. Its function is to physically block blood flow, not to diagnose a condition or disease.
No
The device description clearly outlines physical components made of PEEK and stainless steel, designed for direct patient contact and surgical manipulation. It is a physical surgical instrument, not software.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices intended for use in the collection, preparation, and examination of specimens taken from the human body (such as blood, urine, or tissue) to provide information for diagnostic purposes. This testing is performed outside of the living body (in vitro).
- Device Description and Intended Use: The description clearly states that the PICOCLAMP is a surgical instrument used to "temporarily occlude blood vessels during the anastomosis process." This is a direct surgical intervention performed on the patient's body (in vivo).
- Lack of Diagnostic Function: The device does not analyze specimens or provide diagnostic information. Its function is purely mechanical – to temporarily stop blood flow.
The PICOCLAMP is a surgical instrument, not an in vitro diagnostic device.

Device Description
PICOCLAMP is Ethylene Oxide sterile single-use hemostasis clamp consisting of Polyetheretherketone (PEEK) and stainless steel (SUS series). PICOCLAMP is designed for use during surgery to temporarily occlude blood vessels during the anastomosis process. PICOCLAMP consists of three main direct patient-contacting parts, all of them are streilized; main body, axis, and spring. The body is consisting of two parts; the jaw which is used to occlude the blood vessel temporarily and the grip which functions to open and close jaws using the surgeon hand or the clamp forceps. The axis integrates the body and keep its parts intact. The spring functions to give clamping force to the jaws. Two types of clamps are provided: green color clamps used for arteries temporary occlusion and blue color clamps used for veins temporary occlusion. Both of the artery and vein clamp are having two types: single and double. PICOCLAMP is available in three different sizes; S (Small), M (Medium), and L (Large). PICOCLAMP is used for temporary occlusion of blood vessels with diameters ranging from 0.2mm to 2.0mm. The clipping power applied at the blood vessel differs depending on the size of the clamp and the pressure of the spring selected. Once the anastomosis process is complete, PICOCLAMP is removed from the patient.

Biocompatibility Testing
The following biocompatibility testing was conducted to demonstrate substantial equivalence with the predicate device: Cytotoxicity, Sensitization, Intracutaneous irritation, Acute systemic Toxicity, Pyrogenicity.
Bench Performance Testing
Since no guidance documents or FDA recognized consensus standards exist for the device type, structural and dimensional confirmation, clipping power testing, ability for repeated clamp opening and closing, and resistance to dislodgement testing were conducted as performance testing. Testing reports of both the proposed device (PICOCLAMP) and the predicate device demonstrate that PICOCLAMP is substantially equivalent to the predicate device.
Animal Performance Testing
Animal performance testing was not required to demonstrate safety and effectiveness of the device.
Clinical Performance Testing
Clinical testing was not required to demonstrate the safety and effectiveness of the device.
CONCLUSIONS
After performing non-clinical performance testing, Biocompatibility testing, Sterilization and Shelf-life testing, the data shows that PICOCLAMP is substantially equivalent to the predicate device.

DEVICE DESCRIPTION IV.
PICOCLAMP is Ethylene Oxide sterile single-use hemostasis clamp consisting of Polyetheretherketone (PEEK) and stainless steel (SUS series). PICOCLAMP is designed for use during surgery to temporarily occlude blood vessels during the anastomosis process. PICOCLAMP consists of three main direct patient-contacting parts, all of them are streilized; main body, axis, and spring. The body is consisting of two parts; the jaw which is used to occlude the blood vessel temporarily and the grip which functions to open and close jaws using the surgeon hand or the clamp forceps.

Both of the artery and vein clamp are having two types: single and double. PICOCLAMP is available in three different sizes; S (Small), M (Medium), and L (Large). PICOCLAMP is used for temporary occlusion of blood vessels with diameters ranging from 0.2mm to 2.0mm.

V. INDICATIONS FOR USE
A surgical instrument used to occlude a blood vessel temporarily.
COMPARISON OF TECHNOLOGICAL CHARACTERISTICS WITH THE VI. PREDICATE DEVCE
In terms of technological characteristics, PICOCLAMP does not completely share them with the predicate device. The main differences are the material used for the clamp body, using different sterilization method and a slight change in the device design.
The proposed device's body is made of PEEK (Polyether ether ketone), while the predicate device is made of poly carbonate. Based on the Biocompatibility testing results, Kono Seisakusho Co., Ltd. considers that using different material does not raise different questions of the safety and effectiveness of the proposed device.
The sterilization method of the proposed device is Ethylene Oxide (EO), while the predicate device sterilization method is by radiation. Ethylene Oxide residuals testing results shows that the difference of the sterilization method does not affect the safety and effectiveness of the proposed device.
The proposed device's body contains "hook" at the top of its jaw to help holding the blood vessel. Bench performance testing results of both the proposed device and the predicate device shows that this design change does not impact the proposed device's performance.
