The laser system generates non-ionizing radiation which is transferred to the relevant anatomical treatment site through surgical fibers that serve as the delivery vehicle from the laser energy generator to the treatment site. The laser system includes a universal, three-pedal footswitch that can operate in wired and wireless mode for hands-free control. The system can utilize a customer-supplied, medical grade external surgical monitor to display endoscope video as well as the device's user interface. The laser system's front panel includes a surgical fiber connection port and a touchscreen with a user interface. The rear panel includes electrical and interface cable ports. The laser system may be placed on an optional, mobile cart. The system can utilize an auxiliary video monitor to display operating parameters. The laser system can operate at a maximum power output of 60 watts in CW, regular and advanced Pulsed modes with a maximum frequency output of 2400 Hz and a maximum pulse energy of 6 Joules. The laser system must be operated with the IPG Medical Surgical Fibers. The surgical fibers are flexible optical fibers that deliver the laser energy to the target tissue. The surgical fibers are the only patient-contacting components of the IPGTFL-02. | | | {6} The purpose of this 510(k) is to add an optional module called StoneSense™ for lithotripsy procedures. During these procedures it is possible that the fiber tip loses contact or quasi-contact with the stone which is undesirable. The module is designed to detect if the object in contact or quasi-contact with the distal fiber tip is "Stone" or "Not Stone". If Stone is not detected, the system will not allow emission of the laser. The addition of Stone sense will add an indication for the device. Also, three advanced power modes have been added: - Fragmentation Pulse - Special pulse shape, optimized for stone ablation into large fragments. - Minimal Carbonization Pulse - Special pulse shape for soft tissues vaporization, incision and excision with minimization of tissue carbonization. - Enucleation Pulse - Special pulse shape, developed for enucleation procedure to maximize thermo-mechanical separation of adenomic tissue and capsule with simultaneous strong hemostasis effect. # Intended Use/Indications for Use 21 CFR 807.92(a)(5) The IPGTFL-02 is intended for incision, excision, resection, ablation, coagulation, hemostasis, and vaporization of soft tissue, with or without an endoscope, in the following indications: urology, lithotripsy, gastroenterological surgery and gynecological surgery. Urology: - Ablation of Benign Prostatic Hyperplasia (Hypertrophy) [BPH] - Laser Resection of the Prostate (LRP) - Laser Enucleation of the Prostate (LEP) - Laser Ablation of the Prostate (LAP) - Transurethral Incision of the Prostate (TUIP) - Condylomas - Urethral strictures - Lesions of external genitalia - Bladder neck incisions (BNI) - Ablation and resection of bladder tumors, urethral tumors, and ureteral tumors - Endoscopic fragmentation of urethral, ureteral, bladder, and renal calculi with integrated detection of calculi and mucosal tissue by StoneSense module that reduces exposure of mucosal tissue to laser energy and reduces resulting damage to mucosal tissue - Treatment of distal impacted fragments remaining in the ureters following lithotripsy Lithotripsy and Percutaneous Urinary Lithotripsy: - Endoscopic fragmentation of urethral, ureteral, bladder and renal calculi including cystine, calcium oxalate, monohydrate and calcium oxalate dihydrate stones. - Endoscopic fragmentation of renal calculi - Treatment of distal impacted fragments of steinstrasse when guide wire cannot be passed. Gastroenterology: Open and endoscopic gastroenterology surgery (incision, excision, resection, ablation, vaporization, coagulation and hemostasis) including: - Appendectomy - Angiodysplasia - Polyps - Colorectal cancer - Biopsy - Telangiectasias - Gall Bladder calculi - Telangiectasias of the Osler-Weber-Renu disease - Biliary/Bile duct calculi - Vascular Malformation - Ulcers - Gastritis - Gastric ulcers - Esophagitis - Duodenal ulcers - Esophageal ulcers - Non Bleeding Ulcers - Varices - Pancreatitis - Colitis - Hemorrhoids {7} - Mallory-Weiss tear - Cholecystectomy - Gastric Erosions - Benign and Malignant Neoplasm Gynecology: Open and laparoscopic gynecological surgery (incision, excision, resection, ablation, vaporization, coagulation and hemostasis) of soft tissue. ## Indications for Use Comparison **21 CFR 807.92(a)(5)** The indications for use statement has been amended to include the StoneSense module. After the indication of "Endoscopic fragmentation of urethral, ureteral, bladder, and renal calculi" the following was added: "with integrated detection of calculi and mucosal tissue by StonseSense module that reduces exposure of mucosal tissue to laser energy and reduces resulting damage to mucosal tissue." This addition falls within the same intended use as the predicate which is: incision, excision, resection, ablation, coagulation, hemostasis, and vaporization of soft tissue. ## Technological Comparison **21 CFR 807.92(a)(6)** The IPGTFL-02 is similar to the predicate in fundamental technological characteristics. Both devices are Thulium Fiber lasers, with a wavelength of 1920 nm - 1960 nm, peak power of 125, 250 and 500 W, average power of 2-60 W and use optical fiber cable with the identical size and patient contacting materials. There are some technology characteristics that are different. They are described below: The operating modes are similar. Instead of Assistant Mode in predicate, IPGTFL-02 uses Guided Mode. The predicate used the location of the stone, stone size and stone density to determine the recommended treatment parameters. IPGTFL-02 uses location of the stone, flow rate and stone density to determine recommended treatment parameters. It was found that using flow rate instead of stone size allowed better match between relevant clinical situation and optimal laser settings. The surgical fibers are similar to the surgical fibers in the predicate submission. The patient contacting area of the fiber optics cables are identical in both devices. The method of sterilization and SAL of the sterilization cycle remained the same. The shelf life has been extended to 3 years. Both devices have Standard Power Modes, Regular Pulse and Continuous Wave (CW), and Minimal Retropulsion Pulse (MRP) for predicate. IPGTFL-02 has three additional Advanced Power Modes which are: Fragmentation Pulse, Minimal Carbonization Pulse and Enucleation Pulse. Similar to MRP, these three power modes modify the pulse to improve the effect on tissue or stone without compromising safety profile. StoneSense: The StoneSense module is a new feature for lithotripsy procedures. Due to retropulsion (movement of stone during lithotripsy), inadvertent movement of the scope or the patient, or error in positioning of the fiber tip by the operator, it is possible that the fiber tip is no longer in contact or is in quasi-contact with the stone, with laser pulses no longer being incident on the stone but possibly a) on mucosal tissue or b) within the fluid away from the stone, both of which are undesirable. Laser pulses incident on mucosal tissue can cause ablative or coagulative burn injuries, which may lead to unwanted side effects. Laser pulses within the ambient fluid cause heating of the fluid, increasing load on the irrigation system and decrease stone ablation efficiency. IPG Medical has developed StoneSense technology to detect if the object in contact or quasi-contact with the distal fiber tip is "Stone" or "Not Stone". If Stone is not detected, the system will not allow emission of the laser. ## Non-Clinical and/or Clinical Tests Summary & Conclusions **21 CFR 807.92(b)** IEC 60601-1:2005/AC 1:2006/A1:2012/AC1:2014/AMD2:2020 Medical electrical equipment - Part 1: General requirements for basic safety and essential performance IEC 60601-1-2:2014; IEC 60601-1-2:2014/A1:2020 Collateral Standard: Electromagnetic disturbances - Requirements and tests IEC 60601-1-6: Edition 3.2 2020-07 Usability IEC 62366-1: 2015+AMD1:2020 Part 1: Application of usability engineering to medical devices IEC 62304: 2006/AMD1: 2015 Medical device software (SW) IEC 60601-2-22: 2019 Particular requirements for basic safety and essential performance of surgical, cosmetic etc. IEC 60825-1: 2014 Safety of laser products - Part 1: Equipment classification and requirements {8} Ex-vivo testing was completed to compare effects such as fragmentation efficiency, ablation depth, coagulation width and carbonization grade and coagulation of the new power modes to the predicate device. Testing of the StoneSense Module was performed by comparing StoneSense determination of "Stone or "Not Stone" during a simulated procedure with a known value of "Stone or "Not Stone".
