Intended Use

The LAPEX-2000 is indicated for adjunctive use in the temporary relief of hand and wrist pain associated with Carpal Tunnel Syndrome.

Device Story

Lapex 2000 is a low-level laser therapy (LLLT) device; utilizes semiconductor laser diodes to emit 830nm light; operates in continuous or modulated continuous modes; output power 30mW x 3. Device is portable; features LCD monitor for therapy information and key-based operation. Used in clinical settings for adjunctive pain relief; non-invasive application to hand and wrist. Healthcare provider operates device to deliver light therapy; output provides non-painful, non-heating treatment. Intended to provide temporary relief of pain associated with Carpal Tunnel Syndrome, potentially reducing patient discomfort.

Clinical Evidence

Bench testing only. No clinical data provided. Safety and effectiveness supported by bench, electrical safety, EMC, and user testing comparisons to predicate devices.

Technological Characteristics

Low-level laser therapy device; GaAlAs semiconductor laser diodes; 830nm wavelength; 30mW x 3 output power; continuous and modulated continuous modes. Portable form factor with LCD display and keypad interface. Non-heating, non-invasive. Electrical safety and EMC testing performed.

Indications for Use

Indicated for patients experiencing hand and wrist pain associated with Carpal Tunnel Syndrome for temporary relief as an adjunctive therapy.

Regulatory Classification

Identification

An infrared lamp is a device intended for medical purposes that emits energy at infrared frequencies (approximately 700 nanometers to 50,000 nanometers) to provide topical heating.

Special Controls

*Classification.* Class II (special controls). The device, when it is an infrared therapeutic heating lamp, is exempt from the premarket notification procedures in subpart E of part 807 of this chapter subject to the limitations in § 890.9.
