Intended Use

The Hygia Health Services Reprocessed Huntleigh Flowtron® DVT Sleeve is designed to operate in the identical manner as the predicate device, the Huntleigh Flowtron® DVT. It is designed to apply compression to a patient's lower limbs for the prevention of deep vein thrombosis (DVT) as well as the treatment of edema secondary to venous insufficiency. The device is used in both the home and institutional settings on patient populations for which this device applicable.

Device Story

Compressible limb sleeve; provides intermittent pneumatic compression to lower limbs. Input: ambient air via external controller. Operation: controller cycles inflation/deflation of single PVC bladder; compression collapses veins to eject blood toward heart; deflation allows venous refill. Used in home and institutional settings; operated by clinicians or patients. Output: mechanical compression of limb. Benefits: DVT prevention; treatment of venous insufficiency-related edema. Reprocessed via thermal high-level disinfection (HLD) for multi-patient reuse.

Clinical Evidence

Clinical and nonclinical test results indicated substantial equivalence to the predicate. Comparative bench testing assessed compression, pressure control, and timing sequences. No specific clinical trial metrics (e.g., p-values, sensitivity) provided.

Technological Characteristics

Compressible limb sleeve; brushed nylon exterior with polyester foam lining; single PVC bladder; polyester/cotton binding; polyethylene hook fasteners; snap lock connector. Operates via external pneumatic controller. No internal electronics or software.

Indications for Use

Indicated for prevention of deep vein thrombosis (DVT) and treatment of venous leg ulcers and edema due to venous insufficiency. Contraindicated in patients with dermatitis, gangrene, recent skin grafts, untreated infected wounds, recent vein ligation, congestive heart failure, severe arteriosclerosis/ischemic vascular disease, pulmonary edema, known/suspected DVT or phlebitis, or leg deformity.

Regulatory Classification

Identification

A compressible limb sleeve is a device that is used to prevent pooling of blood in a limb by inflating periodically a sleeve around the limb.

#### Statement of Substantial Equivalence 4.

The Hygia Health Services Reprocessed Huntleigh Flowtron® DVT Sleeve employs no new technology other than the method used to reprocess the sleeve in order to allow the device to be utilized more than once. The Hygia Health Services Reprocessed Huntleigh Flowtron® DVT Sleeve is substantially equivalent to the Huntleigh Flowtron® DVT in that the basis of operation for both of the devices is the intermittent inflation of a single bladder, which is placed around the patient's lower limbs. The sleeves are then connected to a controller via a set of connecting tubes that range from 60-inches in length to 120-inches in length. Inflation of the sleeve is accomplished using ambient air and a controller cycle that functions to alternately inflate and deflate the sleeves in a predetermined manner and interval.

The Hygia Health Services Reprocessed Huntleigh Flowtron® DVT Sleeve is substantially equivalent in function, operating parameters, and intended use to the Huntleigh Flowtron® DVT sleeve that is currently commercially available and in distribution. There is no significant change in the device, the predicate Huntleigh Flowtron® DVT sleeve is marked for "single-patient use" only. Hygia Health Services reprocess the sleeve via thermal high-level disinfection (HLD) so as to make the sleeve able to be reused. The Hygia Health Services HLD protocol does not alter the device's efficacy, safety, composition, or intended use.

#### 5. Description of the Device

The Hygia Health Services Reprocessed Huntleigh Flowtron® DVT sleeve is a compressible limb device that, when attached to an approved controller, provides intermittent pneumatic compression. The sleeve is constructed out of brushed nylon with a polyester foam lining. The single bladder is constructed of poly vinyl chloride (PVC), as is the inflation/deflation tube. The binding is a polyester/cotton blend, and the hook fasteners are made of polyethylene. The tube terminates in a snap lock connector. The sleeves are placed around the leg and secured with a hook and loop fastener. As the sleeves compress the leg, veins collapse, increasing the venous pressure thus ejecting the blood upward toward the heart. After compression, the sleeves deflate allowing the veins to refill and bring oxygenated blood to the lower limbs. The controller predetermines the inflation

and deflation sequence. The pressure of compression is determined by the controller and is adjusted by altering the readout on the controller.

#### Intended Use of Device 6.

The Hygia Health Services Reprocessed Huntleigh Flowtron® DVT Sleeve is designed to operate in the identical manner as the predicate device, the Huntleigh Flowtron® DVT. It is designed to apply compression to a patient's lower limbs for the prevention of deep vein thrombosis (DVT) as well as the treatment of edema secondary to venous insufficiency. The device is used in both the home and institutional settings on patient populations for which this device applicable.

#### 7. Technological Characteristics

The technological characteristics of the Hygia Health Services Reprocessed Huntleigh Flowtron® DVT sleeve are identical to the original Huntleigh Flowtron® DVT in overall design, materials, energy source, mode of operation, and performance characteristics.

#### Performance Data 8.

Nonclinical Tests- Comparative bench testing was utilized to assess and prove similarity of function between the Hygia Health Services Reprocessed Huntleigh Flowtron® DVT sleeve and the predicate device, the Huntleigh Flowtron® DVT. All tests found that functional and operational performance characteristics including compression, pressure control, timing sequence, and both safety and operational parameters used when connected to a controller were substantially equivalent.

Clinical Tests- Clinical tests were summarized in support of the premarket notification submission.

Test Conclusions- Clinical and nonclinical test results of the Hygia Health Services Reprocessed Huntleigh Flowtron® DVT Sleeve indicated substantial equivalence in all aspects to the predicate device, the Huntleigh Flowtron® DVT Garment.
