Device Facts

• Record ID: K021588
• Device Name: ELECTRO NEUROMUSCULAR STIMULATOR, MODEL BMLS02-5
• Applicant: Biomedical Life Systems, Inc.
• Product Code: IPF · Physical Medicine
• Decision Date: Feb 13, 2003
• Decision: SESE
• Submission Type: Traditional
• Regulation: 21 CFR 890.5850
• Device Class: Class 2
• Attributes: Therapeutic

Intended Use

External electrical neuromuscular stimulation using biphasic output is indicated as therapeutic adjunct for: prevention or retardation of muscle disuse atrophy; relaxation of muscle spasm; muscle reeducation; maintaining and increasing the range of motion; increasing local blood circulation and as immediate postsurgical stimulation of calf muscles to prevent venous thrombosis.

Device Story

The BMLS02-5 is an electrical neuromuscular stimulator (EMS) providing biphasic electrical output to muscles. It functions as a therapeutic adjunct for muscle reeducation, atrophy prevention, spasm relaxation, range of motion maintenance, circulation improvement, and postsurgical venous thrombosis prevention. The device is intended for clinical or home use under professional guidance. It delivers electrical pulses to the patient's muscles to induce contraction or relaxation, aiding in physical therapy and rehabilitation protocols. Healthcare providers use the device to manage musculoskeletal conditions and post-operative recovery, potentially improving patient mobility and reducing complications associated with muscle disuse.

Clinical Evidence

No clinical data provided; substantial equivalence is based on technological characteristics and intended use.

Technological Characteristics

Powered muscle stimulator; biphasic electrical output; Class II device; 21 CFR 890.5850; Product Code IPF.

Indications for Use

Indicated for patients requiring muscle reeducation, prevention/retardation of disuse atrophy, muscle spasm relaxation, range of motion maintenance/increase, local blood circulation improvement, and immediate postsurgical calf muscle stimulation to prevent venous thrombosis.

Regulatory Classification

Identification

A powered muscle stimulator is an electrically powered device intended for medical purposes that repeatedly contracts muscles by passing electrical currents through electrodes contacting the affected body area.

Dear Mr. Saxon:

We have reviewed your Section 510(k) premarket notification of intent to market the device referenced above and have determined the device is substantially equivalent (for the indications for use stated in the enclosure) to legally marketed predicate devices marketed in interstate commerce prior to May 28, 1976, the enactment date of the Medical Device Amendments, or to devices that have been reclassified in accordance with the provisions of the Federal Food, Drug, and Cosmetic Act (Act) that do not require approval of a premarket approval application (PMA). You may, therefore, market the device, subject to the general controls provisions of the Act. The general controls provisions of the Act include requirements for annual registration, listing of devices, good manufacturing practice, labeling, and prohibitions against misbranding and adulteration.

If your device is classified (see above) into either class II (Special Controls) or class III (PMA), it may be subject to such additional controls. Existing major regulations affecting your device can be found in the Code of Federal Regulations, Title 21, Parts 800 to 898. In addition, FDA may publish further announcements concerning your device in the Federal Register.
