The device description and performance studies focus on the mechanical properties and biocompatibility of a physical stent, with no mention of software, algorithms, or data processing.
Yes
The device is intended for intubation to treat nasolacrimal conditions like stenosis or obstruction, aiming to improve patient health by addressing these pathologies.
No
The device is a bicanalicular intubation device intended for the treatment of epiphora, a clinical condition, rather than for diagnosing a condition. Its function is to facilitate drainage, not to provide diagnostic information.
No
The device description clearly describes a physical medical device made of silicone tubes and guides, intended for surgical intubation. There is no mention of software as a component or the primary function of the device.
No, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- IVD Definition: In Vitro Diagnostics are devices used to examine specimens taken from the human body (like blood, urine, tissue) to provide information for diagnosis, monitoring, or screening.
- Nunchaku Stents Function: The Nunchaku stents are implanted devices used to physically open and maintain the patency of the nasolacrimal duct. They are used in vivo (within the body) to treat a physical condition (obstruction or stenosis).
- Lack of Specimen Analysis: The device description and intended use do not involve the analysis of any biological specimens.
Therefore, based on the provided information, the Nunchaku stents are a medical device used for surgical intervention, not an In Vitro Diagnostic.

Summary of Performance Studies
Bench top testing was performed on samples before and after sterilization to validate the mechanical characteristics of the silicone tube. Testing included an evaluation of guide detachment during insertion, the mechanical integrity of the device during guide insertion and removal, and tensile strength testing. All non-clinical test results met the established specifications for the device. Test results on the silicone material demonstrated that the silicone was of sufficient tensile strength to resist breakage and device pull-out. The biocompatibility of the raw materials was tested to the applicable ISO standards for cytotoxicity (MEM elution assay), irritation (intracutaneous reactivity in rabbits), sensitization (guinea pig maximation), systemic toxicity, muscular implantation, and to USP standards for endotoxins. The biocompatibility test results met the required specifications for all tests. The biocompatibility of the finished devices were also tested for Ethylene oxide sterilization studies, shipping and package integrity studies were performed according to the applicable standards; and, the test results support the shelf-life and storage conditions for the device.

General Description
The Nunchaku is a bicanalicular intubation device for the treatment of epiphora in patients 12 months and older. The device consists of two lateral silicone tubes connected to a silicone body that is delivered pre-mounted on two guides facilitate insertion of the Nunchaku and are completely removed once insertion of the device is complete. The Nunchaku comes in two different model lengths (90 or 105 mm depending on length of tube required) and is provided as a sterilized product.
Intended Use
The Nunchaku stents are intended for use for nasolacrimal intubation in patients 12 months and older. Indications for nasolacrimal intubation performed with the Nunchaku are:
- . Canalicular pathologies (e.g., congenital or acquired stenosis, lacerations)
- During dacryocystorhinostomy ●
- Congenital lacrimal duct obstruction
Comparison of Technological Characteristics
The Nunchaku, Crawford Bicanaliculus Intubation, and Self-Retaining Bicanaliculus Intubation Set II manufactured by FCI are identical, or nearly identical, in every respect except the Nunchaku is pre-mounted on two metal guides to facilitate insertion of the device. The Nunchaku (manufactured by FCI) and the Lacriflow (manufactured by Kaneka) are also identical, or nearly identical, in every respect including pre-mounting onto two metal guides, except that the Lacriflow is manufactured from a polyurethane material. All three devices have a stent body (tube) that is manufactured from nearly identical grade silicone (Nunchaku, Crawford Bicanaliculus Intubation, Self-Retaining Bicanaliculus Intubation Set II) or medical grade polyurethane material (Lacriflow). The Nunchaku, Crawford Bicanaliculus Intubation, and Self-Retaining Bicanaliculus Intubation Set II are manufactured using the same processes and gluing methods, are ethylene oxide sterilized, and provided in similar packaging. The stainless steel materials used in each device are medical grade with well characterized mechanical and biocompatibility properties. The Nunchaku and Crawford Bicanaliculus Intubation are used with a sizer that is packaged and sold separately by FCI S.A.S.. The Self-Retaining Bicanaliculus Intubation Set II uses the same sizer, which is pre-packaged with the Self-Retaining device along with a disposable dilator.
Brief Summary of Non-Clinical Tests and Results
The manufacturing process was validated, demonstrating the capacity of FCI S.A.S. and FCI SUD to manufacture the Nunchaku. Bench top testing was performed on samples before and after sterilization to validate the mechanical characteristics of the silicone tube. Testing included

an evaluation of guide detachment during insertion, the mechanical integrity of the device during guide insertion and removal, and tensile strength testing. All non-clinical test results met the established specifications for the device. Test results on the silicone material demonstrated that the silicone was of sufficient tensile strength to resist breakage and device pull-out. The biocompatibility of the raw materials was tested to the applicable ISO standards for cytotoxicity (MEM elution assay), irritation (intracutaneous reactivity in rabbits), sensitization (guinea pig maximation), systemic toxicity, muscular implantation,and to USP standards for endotoxins. The biocompatibility test results met the required specifications for all tests. The biocompatibility of the finished devices were also tested for Ethylene oxide sterilization studies, shipping and package integrity studies were performed according to the applicable standards; and, the test results support the shelf-life and storage conditions for the device.
From the testing, it can be concluded that the Nunchaku performs as intended and is constructed of biocompatible materials.
Basis of Substantial Equivalence
The Nunchaku is substantially equivalent to the Crawford Bicanaliculus Intubation and Self-Retaining Bicanaliculus Intubation Set II in material, intended use, basic design concept, sterilization methods, and biocompatibility. The Nunchaku is also substantially equivalent to the Lacriflow in intended use, design concept, and dimensions. The main difference is that the Nunchaku, Lacriflow, and Self-Retaining Bicanaliculus Intubation Set II devices are all premounted onto metallic guides to facilitate insertion; whereas, the Crawford Bicanaliculus Intubation device has a flexible metallic guide affixed to each end of the silicone tube that is removed nasally after fixation of the device is confirmed as part of the stent placement procedure. The Nunchaku, Crawford Bicanaliculus Intubation, and Self-Retaining Bicanaliculus Intubation Set II are both manufactured by FCI S.A.S. and distributed in the U.S.A. by FCI Ophthalmics, Inc. The Lacriflow is manufactured by Kaneka Corporation in Japan and distributed in the U.S.A. by Kaneka Pharma America, LLC.
