The Fitbit has just been launched. It accurately tracks calories burned, steps taken, distance traveled and even sleep quality. The Fitbit contains a 3D motion sensor similar to the one found in the Nintendo Wii. It works by tracking your movement in three dimensions and converts this data into useful information about your daily activities.

The main improvement over the Nike + Ipod sensor is its wireless capacity. Anytime you walk past the included wireless base station, data from your Fitbit is automatically uploaded to Fitbit.com. The Web site's detailed data includes a food budget, calories burned, steps taken, and daily trends.

In the U.S., Juvéderm™ injectable gel is indicated for injection into the mid to deep dermis for correction of moderate to severe facial wrinkles and folds such as nasolabial folds.

The key ingredient of Juvéderm is hyaluronic acid which is a naturally occurring, biodegradable complex sugar found in the human body and in all living animals. Among other things, hyaluronic acid hydrates the skin and adds volume, contributing to the overall appearance of the skin.

As we age, the ability of cells to produce hyaluronic acid diminishes, often resulting in facial wrinkles and folds as the skin loses volume. Juvéderm is administered in small doses by intradermal injection directly into wrinkles and folds, such as nasolabial folds, temporarily filling and augmenting the treated area.

Heartware is an Australian company that manufactures a Ventricular Assist System. It's designed to help patient's with weakened hearts by removing blood from the left side of the heart and pumping the blood into the aorta.

A miniaturized centrifugal pump called the HVADTM is designed to rest inside the chest and can generate up to 10 liters per minute of blood flow. Two small motor stators inside the pump housing cause an impeller within the device to rotate, pumping blood through the system.

In the entire branch of dentistry having a Dental Implant is the most difficult form of dental surgery. It is generally carried out only by an orthodontist who holds a MDS degree (Master of dental surgery).

Dental Implant is a procedure of implanting an artificial tooth into the gums. The implant is a permanent solution for teeth loss and is considered as an advanced dental cosmetic treatment. There was a time when Dental Implants were considered as an exceptionally risky procedure but today the situation has changed. Nowadays, different advanced technologies are deployed for different forms of dental treatments and orthodontic procedures. This has invariably increased the quality of treatment and has provided for guaranteed and quicker results. Nevertheless, these procedures have become highly expensive compared to the olden times. A new age Dental Implant is more durable and more secure. With the high level of success rates exhibited by this complex procedure more and more people are opting for dental implants in order to fix their missing, chipped or broken dentures.

The Verichip™ is the first human-implantable RFID chip and personal health record, cleared for medical use by the United States FDA. The $200 chip is about the size of a grain of rice and inserted just under the skin in the back of your right arm. The VeriMed™ Health Link system, incorporates the RFID microchip (the VeriChip), a handheld scanner and and an online, electronic, personal health record.

Recent advances mean the chips are now also able to read bio markers such as glucose levels. This enables diabetics to get live readings of their glucose levels without having to prick their fingers.

In September 2009 Verichip gained the exclusive rights from their development partner RECEPTORS LLC to use "artificial receptors” technology to develop a virus triage detection system for the H1N1 virus also known as swine flu. This technology can also be applied to detect other viruses and biological threats such as Staphylococcus aureus (MRSA).

Russian scientists have developed a new laser which can correct eyesight without cutting the surface of the eye. Laser surgery to restore eyesight has been performed for nearly two decades, and every year the procedure becomes safer and easier. Currently, it can be done using two lasers, one opening the eye's surface and the other working with the cornea itself. But soon even this futuristic technology may seem ancient as true technology of the 21st Century steps in.

“Our laser is able to penetrate the eye's cornea without damaging its surface. As a result we can make the needed changes inside the eyeball without having to open it first,” shares Konstantin Lapshin, senior researcher at Physics Instrumentation Centre. The femtosecond laser generates impulses of light less than one billionth of a second long. Such beams can cut or evaporate matter when several lasers are aimed at one spot.

St. Jude Medical, Inc. makes the “Brio” system, which is a pacemaker-like device used to treat the symptoms of Parkinson’s disease. Its currenlty the world’s smallest, longest-lasting rechargeable deep brain stimulation (DBS) device for treating Parkinson’s symptoms. Slightly larger than a typical man’s watch, the neurostimulator has a thin 10 mm profile and weighs 29 grams (approximately 1 oz). The device also has the greatest recommended implant depth of any rechargeable DBS device, making the neurostimulator less noticeable and more comfortable for patients.

The system has received CE Mark approval of its Brio™ neurostimulator in 2009. In March 2010 it was approved by the Australian Therapeutic Goods Administration, however it hasn’t yet received FDA approval in the U.S.
