Intended Use

The C-Boot™ is a prescriptive device that induces controlled compression of the calf, the foot or a combined compression of both. The C-Boot™ is intended to assist patients, suffering from lymphatic or venous disorders, by treating many conditions including: - Prevention of deep vein thrombosis (DVT) - Enhancement of blood circulation - Reduction of post-operative pain and swelling - Reduction of wound-healing time - Stasis dermatitis - Treatment and assist healing of cutaneous ulceration - Venous stasis ulcers - Leg ulcers - Chronic venous insufficiencies - Reduction of edema - Prevent pooling of fluids in limbs - Lymphedema

Device Story

Wearable pneumatic compression boot for peripheral vascular and lymph disorders; utilizes mechanical energy generated by patient movement and weight transfer during walking to inflate sleeves; provides sequential, cyclical compression to calf/foot; replaces electrical pumps found in traditional systems with self-powered mechanical actuation; operates via patient mobility; enhances lymphatic/venous return; reduces edema and promotes healing; used by patients to manage chronic conditions; clinical benefit derived from harnessing gravitational force and body weight to drive therapeutic massaging effect on vessel walls.

Clinical Evidence

Bench testing only. Functional, performance, and safety testing conducted; comparative analysis performed against predicate devices (WizAir and Lympha Press) to demonstrate substantial equivalence.

Technological Characteristics

Wearable pneumatic compression boot; mechanical energy source (patient movement/weight transfer) vs electrical; sequential, intermittent compression; 1-2 cycles per minute; fabric construction; non-networked; non-electronic.

Indications for Use

Indicated for patients with lymphatic or venous disorders requiring compression therapy for DVT prevention, circulation enhancement, edema reduction, wound healing, and management of venous/leg ulcers or chronic venous insufficiency. Contraindicated in patients with advanced peripheral arterial occlusive disease, decompensated heart disease, specific phlebitis, phlegmasia coerulea dolens, sensory loss/neuropathy in lower limbs, supportive dermatosis, or primary chronic arthritis.

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.

Predicate Devices

• WizAir™ Ambulant Pneumatic Compression System (K002287)
• Lympha Press® (K810338)

Lymph and Venous Insufficiency System

{1}------------------------------------------------

## 7. Predicate Devices

The "C-Boot® Lymph and Venous-Insufficiency System" is substantially equivalent to the commercially available "WizAir™ Ambulant Pneumatic Compression System" (of MCS), 510(k) number K002287 cleared on 25-Aug-2000:

It is also substantially equivalent to the commercially available Lympha Press® (of Mego-Afek), 510(k) number K810338 cleared on 20-Oct-1981.

## 8. Device Description

C-Boot Ltd. introduces a wearable pneumatic compression technology embodied in a therapeutic boot that has the potential to increase treatment efficacy and improve the quality of life for peripheral vascular and lymph distorders patients.

C-Boot's solution integrates the technological advantages of dynamic compression pumps, that enable preset sequential pressure control to individualize treatment regimes, with the mobility benefit of static compression stockings, that activate the calf muscle pump and strengthened the body's natural tendency to enhance lymphatic and venous return.

The device relates to a self-powered compression devices and methods for promoting circulation and therapeutic compression: It is comprising a pump, a plurality of sleeves or limb massager, which utilizes sequential, cyclical pressure, energy or vector forces, to aid circulation in a body part such as the limbs. The inflatable sleeves are filled with air by the pump and transmit massaging movement to the vessel walls whenever the patient wearing the device - walks or transmits body's weight from one leg to another. The pressure generated is a function of the user's body weight and gravitational force. The device provides methods to harness energy generated during movement and weight transfer and uses the energy for compressing to create a massaging effect on the circulation and the muscular-skeletal system.

## 9. Indications for Use

The C-Boot™ is a prescriptive device that induces controlled compression of the calf, the foot or a combined compression of both.

The C-Boot™ is intended to assist patients, suffering from lymphatic or venous disorders, by treating many conditions including:

- ਕ. Prevention of deep vein thrombosis (DVT)
- Enhancement of blood circulation b.
- Reduction of post-operative pain and swelling C.
- d. Reduction of wound-healing time
- e. Stasis dermatitis
- f. Treatment and assist healing of cutaneous ulceration
- g . Venous stasis ulcers
- Leg ulcers h.
- Chronic venous insufficiencies i.
- i. Reduction of edema
- Prevent pooling of fluids in limbs k.
- -Lymphedema

## 10. Contraindications

The C-Boot™ should not be used in the following cases: Advanced peripheral arterial occlusive diseases (calves pain while walking), Decompensated heart disease, Specific phlebitis, Phlegmasia coerulea dolens (swollen blue limb), Diabetic patients with lack of reduced sensation in lower limb or foot, Supportive dermatosis, Intolerance of C-Boot™ fabric, sensory disturbances of the limb, Advance peripheral neuropathy, Primary chronic arthritis.

{3}------------------------------------------------

## 11. Technological Characteristics and Substantial Equivalence

The C-Boot™ has combined indications of its two (2) predicate devices - WizAir™ and Lympha Press®- into one product. All three (3) devices have same shape of surrounding sleeves, inflation mode (sequential), mode of Compression (intermittent), number of Cycles (1-2 per minute) and are made all of basically same materials.

The main differences are the dynamic compression pumps, the overlapping-massaging-movements and the mechanical power source of C-Boot™ (compared to an electrical source of the other predicate devices), which raise neither safety nor effectiveness questions, as C-Boot™ functions within same boundaries of performances.

## 12. Performance Data

A series of functional, performance and safety testing, including comparative analysis to Mego-Afek® and WizAir™ - demonstrates that C-Boot™ is substantially equivalent to Mego-Afek® and WizAir™, without raising new safety and/or effectiveness issues.
