Product Description
The CalfPad™ garments and A-V Impulse System are designed to increase venous blood flow in order to help prevent deep vein thrombosis and pulmonary embolism in at-risk patients.
CalfPad- Closely replicates the natural physiological process of mobilisation.
- Effectively reduces stasis, the principal risk factor for DVT formation.
- Easy to use – Easy to wear.
Indication
The CalfPad garments and A-V Impulse System are designed to increase venous blood flow in order to help prevent deep vein thrombosis and pulmonary embolism in at-risk patients.
The A-V Impulse System and accessories offer a clinically effective, non-invasive method of mechanical prophylaxis designed to reduce the incidence of DVT after all major types of surgery including orthopaedic, trauma, urological and general surgery. A-V Impulse System is also suitable for other patient groups including neurology, critical care, general medical and obstetrics.

Clinical References
Clinical studies and Consensus Groups have confirmed that Intermittent Pneumatic Compression (IPC) results in a total DVT relative risk reduction of 60.8% in orthopaedics and 69% in general surgery.

Testimonials
“We could see the value of using calf compression to prevent deep vein thrombosis, but the devices I had used in the past were cumbersome and non-physiological. The design for CalfPad was initiated because of our desire to make a device available that actually mimicked the natural physiological process of mobilisation and was easy for the nurse to apply and the patient to wear”. Mr Richard Johnson, MBChB BSc(Hons) MRCS. Specialist Registrar in Breast Surgery, South Manchester University Hospital.
“It is widely recognised that ambulatory exercise is the most effective form of thromboprophylaxis, yet I know of no calf compression garments that actually mimics this process. CalfPad now allows the clinician to choose a method of mechanical compression for the calf that mimics the process as nature intended. This is an evolution in mechanical compression”. Mr Nile Allaf. BSc, MBChB, MRCS(Eng). Specialist Registrar, Transplant and Vascular Surgery, Manchester Royal Infirmary.

Contraindications
The CalfPad garment may not be recommended for patients with the following:
- Any local leg condition in which sleeves would interfere, such as dermatitis, vein ligation (immediate post-operative), gangrene or recent skin graft.
- Severe arteriosclerosis or other ischaemic vascular disease.
- Extreme deformity of leg.
- Massive oedema of legs or pulmonary oedema from congestive heart failure or any condition where an increase in fluid to the heart may be detrimental.
- Suspected pre-existing deep vein thrombosis.
- Pulmonary embolism.
- When increased lymphatic or venous return is not desirable.
If you are unsure of any contraindications refer to the patient’s physician before using the device. For contraindications 1, 2, and 3 we recommend use of the ImPad® rigid sole foot garment or ImPad One™ foot garments as an alternative method of prophylaxis.
