Intended Use

SureFlex™ and AccuFlex™ are intended for use in laser-based surgical applications, including but not limited to endoscopic, laparoscopic and open surgical procedures involving vaporization, ablation and fragmentation of calculi (urinary and biliary) and surgical procedures involving vaporization, abaltion, coagulation, hemostasis, excision, resection and incision of soft and cartilaginous tissue. While designed primarily for holmium (Ho:YAG) lasers, SureFlex™ and AccuFlex™ fibers may be used with any laser wavelength between 500nm and 2200nm that have been cleared for surgical use including, but not limited to frequency doubled Nd: YAG (KTP) lasers, argon lasers, diode lasers, alexandrite lasers, ruby lasers, dye lasers, Nd:YAG lasers and Tm:YAG lasers.

Device Story

SureFlex and AccuFlex are laser lithotripsy fibers designed for delivery of laser energy to target tissue or calculi. Fibers function as optical waveguides, transmitting energy from external surgical lasers (500nm–2200nm range, primarily Ho:YAG) to the surgical site. Used in endoscopic, laparoscopic, or open procedures by surgeons to perform lithotripsy, tissue ablation, or hemostasis. Device acts as a passive conduit for laser energy; output is determined by the connected laser system settings. Benefits include precise energy delivery for stone fragmentation and soft tissue management in minimally invasive settings.

Clinical Evidence

No clinical data provided; bench testing only.

Technological Characteristics

Optical fiber delivery system for laser energy. Compatible with laser wavelengths 500nm–2200nm. Designed primarily for Ho:YAG lasers. Passive waveguide technology.

Indications for Use

Indicated for patients requiring laser-based surgical procedures including vaporization, ablation, and fragmentation of urinary and biliary calculi, and vaporization, ablation, coagulation, hemostasis, excision, resection, and incision of soft and cartilaginous tissue. Suitable for endoscopic, laparoscopic, and open surgical procedures.

Regulatory Classification

Identification

(1) A carbon dioxide laser for use in general surgery and in dermatology is a laser device intended to cut, destroy, or remove tissue by light energy emitted by carbon dioxide.(2) An argon laser for use in dermatology is a laser device intended to destroy or coagulate tissue by light energy emitted by argon.
