The summary describes a laser applicator system with different fiber types for delivering laser energy to soft tissue. There is no mention of any software, algorithms, or data processing that would suggest the use of AI or ML. The performance studies focus on the physical effects of the laser and the biocompatibility of the materials, not on any intelligent analysis or decision-making by the device.
Yes
The device is indicated for use to necrotize or coagulate soft tissue through interstitial irradiation or thermal therapy, which are therapeutic medical interventions.
No
Explanation: The device is indicated for therapeutic purposes (necrotizing, coagulating, vaporization, cutting, ablation) of soft tissue, not for diagnosing conditions.
No
The device description explicitly details physical components (Laser Diffusing Fiber, Cooling Catheter System, Bare Tip Fiber) which are hardware, not software.
Based on the provided information, this device is not an IVD (In Vitro Diagnostic).
Here's why:
- Intended Use: The intended use clearly states that the device is used to "necrotize or coagulate soft tissue through interstitial irradiation or thermal therapy" and for "vaporization, cutting, ablation and coagulation of soft tissues." These are therapeutic procedures performed directly on the patient's body.
- Device Description: The description details components like laser fibers and cooling catheters designed to deliver energy to tissue. This aligns with a therapeutic device, not a diagnostic one.
- Lack of Diagnostic Elements: There is no mention of analyzing samples (blood, urine, tissue, etc.) or providing diagnostic information about a patient's condition. IVDs are used to diagnose diseases or conditions.
The Visualase Cooled Laser Applicator System is a therapeutic medical device used for surgical procedures involving soft tissue.

Intended Use / Indications for Use
The LDF and CCS are indicated for use to necrotize or coagulate soft tissue through interstitial irradiation or thermal therapy in medicine and surgery in cardiovascular thoracic surgery (excluding the heart and the vessels in the pericardial sac), dermatology, ear-nose-throat surgery, gastroenterology, general surgery, gynecology, head and neck surgery, neurosurgery, plastic surgery, pulmonology, radiology, and urology, for wavelengths 800nm through 1064nm,
The Bare Tip Fiber (BTF) is intended for use in vaporization, cutting, ablation and coagulation of soft tissues with or without scopes or handpieces, for contact or non-contact surgery in medicine and surgery in cardiovascular thoracic surgery (excluding the heart and the vessels of the pericardial sac), dermatology, earnose-throat surgery, gastroenterology, general surgery, gynecology, head and neck surgery, neurosurgery, plastic surgery, pulmonology, radiology and urology for the wavelength range of 800nm through 1064nm.

Device Description
The VCLAS family consists of three components, the LDF, CCS, and BTF. The LDF and BTF transmit laser energy to the tissue situated at their distal regions. The LDF is comprised of a standard silica fiber optic cable affixed with a diffusing tip assembly. The diffusing tip assembly is comprised of a plastic tube that is filled with a transparent matrix in which light dispersing particles are embedded. The distal end of the tube is sealed with a higher concentration of scattering particles in a conical structure to prevent significant forward transmission of energy.
The LDF may be used with a cooling catheter, in particular the compatible CCS, but such a catheter is not required. The CCS can be employed with or without coolant flow. The use of coolant provides cooling for the surfaces of the CCS in contact with both the tissue and the LDF.
The BTF is comprised of a standard silica fiber optic cable identical to fiber optic used in the LDF. The distal end of the BTF is terminated in a flat, polished face and is designed for use in both contact and non-contact applications.

Summary of Performance Studies
Engineering studies have demonstrated the substantial equivalence of the Laser Diffusing Fiber (LDF) to the SLT Diffuser Fiber Delivery Systems (K 010041).
The studies concluded that the treated tissue displayed an ellipsoidal coagulation area surrounding the diffusing region of the laser diffusing fiber. In all instances, the fiber and lasers functioned as intended and performed in a manner similar to the predicate device when used in accordance with the labeled directions for use and specified indications.
The materials used in the Visualase Laser Diffusing Fiber (LDF). Cooling Catheter System (CCS), and Bare Tip Fiber (BTF) were determined to be biocompatible according to appropriate international test standards.

Description of Device
The VCLAS family consists of three components, the LDF, CCS, and BTF. The LDF and BTF transmit laser energy to the tissue situated at their distal regions. The LDF is comprised of a standard silica fiber optic cable affixed with a diffusing tip assembly. The diffusing tip assembly is comprised of a plastic tube that is filled with a transparent matrix in which light dispersing particles are embedded. The distal end of the tube is sealed with a higher concentration of scattering

particles in a conical structure to prevent significant forward transmission of energy.
The LDF may be used with a cooling catheter, in particular the compatible CCS, but such a catheter is not required. The CCS can be employed with or without coolant flow. The use of coolant provides cooling for the surfaces of the CCS in contact with both the tissue and the LDF.
The BTF is comprised of a standard silica fiber optic cable identical to fiber optic used in the LDF. The distal end of the BTF is terminated in a flat, polished face and is designed for use in both contact and non-contact applications.
Indications for Use
The LDF and CCS are indicated for use to necrotize or coagulate soft tissue through interstitial irradiation or thermal therapy in medicine and surgery in cardiovascular thoracic surgery (excluding the heart and the vessels in the pericardial sac), dermatology, ear-nose-throat surgery, gastroenterology, general surgery, gynecology, head and neck surgery, neurosurgery, plastic surgery, pulmonology, radiology, and urology, for wavelengths 800nm through 1064nm,
The Bare Tip Fiber (BTF) is intended for use in vaporization, cutting, ablation and coagulation of soft tissues with or without scopes or handpieces, for contact or non-contact surgery in medicine and surgery in cardiovascular thoracic surgery (excluding the heart and the vessels of the pericardial sac), dermatology, earnose-throat surgery, gastroenterology, general surgery, gynecology, head and neck surgery, neurosurgery, plastic surgery, pulmonology, radiology and urology for the wavelength range of 800nm through 1064nm.
Comparison to Predicate Device
The Laser Diffusing Fiber (LDF) and Cooling Catheter System (CCS) have been shown to be substantially equivalent to the SLT Diffuser™ fiber (K010041). The Bare Tip Fiber (BTF) has been shown to be substantially equivalent to the bare tip fiber marketed with the Indigo Diffuser Fiberoptic (K963081). Differences were determined to be minor and are each within the specifications listed by the predicate devices and does not raise any concerns regarding the overall safety and effectiveness of the device.
Non-clinical Performance Tests:
Engineering studies have demonstrated the substantial equivalence of the Laser Diffusing Fiber (LDF) to the SLT Diffuser Fiber Delivery Systems (K 010041).
The studies concluded that the treated tissue displayed an ellipsoidal coagulation area surrounding the diffusing region of the laser diffusing fiber. In all instances,

the fiber and lasers functioned as intended and performed in a manner similar to the predicate device when used in accordance with the labeled directions for use and specified indications.
The materials used in the Visualase Laser Diffusing Fiber (LDF). Cooling Catheter System (CCS), and Bare Tip Fiber (BTF) were determined to be biocompatible according to appropriate international test standards.
Conclusion
BioTex has demonstrated the Visualase Laser Diffusing Fiber (LDF), Cooling Catheter System (CCS), and Bare Tip Fiber (BTF) are substantially equivalent to the predicate devices based on design, test results, and indications for use.
