In mice, the implants cut the number of tumour cells that migrated to secondary sites like the lungs.
but the implant could boost people chances of survival by identifying early on that cancer cells are on the move allowing the patient to begin chemotherapy right away.
The new implant should in theory attract a wide range of cancer cells although so far the team have shown only it works for one tumour type other than breast cancer,
the implant could even be removed and the cells analysed to see which cancer drugs they are most susceptible to.
The perforated center section of the implant is the prosthetic sternum. Four thin rods on the left mimic ribs.
The eight clamps on either side attach the implant to bone. Screws hold the clamps in place.
They manufactured the implant with a $1. 3 million metal printer at a government-run lab. The printer uses an electron beam to melt titanium powder,
"But for complex and customized implants, the cost to print them is more affordable and the time to produce it is shorter than with traditional manufacturing,"Crystal Ladiges,

the transmitting power of the magnetic signals sent through the body is expected to be many times lower than that of MRI SCANNERS and wireless implant devices.
#Antimicrobial film for future implants The implantation of medical devices is not without risks. Bacterial or fungal infections can occur
and the body's strong immune response may lead to the rejection of the implant. Researchers at Unit 1121"Biomaterials and Bioengineering"(Inserm/Strasbourg university) have succeeded in creating a biofilm with antimicrobial, antifungal and anti-inflammatory properties.
It may be used to cover titanium implants (orthopaedic prostheses, pacemakers...prevent or control postoperative infections. Other frequently used medical devices that cause numerous infectious problems, such as catheters, may also benefit.
This may cause the implant to be rejected. These infections are caused mainly by bacteria such as Staphylococcus aureus,
which lead to an immune response that compromises the success of the implant. Antibiotics are used currently during surgery
or to coat certain implants. However, the emergence of multi-resistant bacteria now restricts their effectiveness.
in particular catestatin, to prevent possible infection around the implant. This is an alternative to the antibiotics that are used currently.
that the presence of the film on the implant suppresses the activation of inflammatory markers normally produced by immune cells in response to the implant.
Researchers conclude that this film may be used in vivo on implants or medical devices within a few years to control the complex microenvironment surrounding implants

#Physiologists uncover a new code at the heart of biology UT Southwestern physiologists trying to understand the genetic code have found a previously unknown code that helps explain which protein should be created to form a particular type of cell.
"Another of our goals is to use calcium phosphate fibers and biocompatible plastics to design surgical implants."
Once the implant is colonized by germs, the result is an inflammatory reaction, which can result in bone atrophy.
and improve the long-term effectiveness of the implant, researchers at the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM in Bremen have developed a new type of implant coating in cooperation with industry partners.
The Dentaplas coating helps prevent the growth of bacteria, thus allowing the implant to properly take hold
and thereby form a faster and more permanent bond with the jawbone. The trick to this lies in combining surface materials that feature physical as well as chemical properties."
This allows the silver ions to penetrate the outermost plasma polymer layer over a set period of time deemed necessary to properly integrate the implant.
In trials using finished implants and titanium test samples the IFAM researchers demonstrated that the Dentaplas coating is not only antimicrobial but also fully biocompatible and sterilizable.
Here, they subjected the Dentaplas coated implants to the rigors of being screwed into place using the instruments found in modern dental practices.
#This Robotic Hand Wired to a Brain Implant Restored a Paralyzed Man Sense of touch In the last few years,
a paralyzed 28-year-old man reported a ear-naturalsense of touch from a sensor-laden robotic hand wired to a brain implant.
however, robotic arms wired directly to the brain via an implant have been primarily one-way devicesllowing action but not yielding sensory information.
however, the only way to link up to a robotic arm is directly through the brain by way of an implant.
The implant was wired then to a robotic hand built by the Applied Physics laboratory at Johns Hopkins. Using advanced pressure sensors,
the hand converts physical sensations into electrical signals that are communicated to the brain through the brain implant.
invasive surgery and wired brain implants are not an ideal solution. And limited to pressure,

#Unusual skin cancer linked to chronic allergy from metal orthopedic implant In rare cases patients with allergies to metals develop persistent skin rashes after metal devices are implanted near the skin.
Metal alloys help make orthopedic implants stronger and more durable. But people with sensitivity to these metals which include nickel cobalt
After the surgery the patient developed a skin rash on her ankle near the location of the implant.
The patient turned out to be allergic to nickel in the implant which led surgeons at the other hospital to remove it.
The finding suggests that patients with metal implants near the skin may need to be monitored for this type of inflammation according to the researchers.
and further research on whether physicians should test for metal sensitivity in patients preparing for surgery to get these types of implants.
Chronic inflammation from metal implants can cause joint pain and swelling and contribute to joint failure.
And when these implants are placed near the skin fewer than 5 percent of patients develop an inflammatory rash related to the implant.
To investigate whether inflammation from the implant contributed to the tumor the researchers studied mouse models of contact allergy.
If the contact allergen remains a long time--as was the case with the patient's implant--different inflammatory cells
and was still present in her skin even after the implant was removed. It's as if a patient allergic to poison ivy kept putting poison ivy on the skin.
To prevent such adverse events the researchers suggested that the potential for allergic reactions to metal implants be assessed in patients who have had the implants
Allergen-free versions of some implants are said available Demehri. These versions may cost more or be less durable
Similar to metal implants some dental restoration materials and tattoo inks contain substances associated with allergic reactions and cancers on the skin or in the mouth.
A novel osseointegrated (bone-anchored) implant system gives patients new opportunities in their daily life and professional activities.
Because the implant is a bidirectional interface, it can also be used to send signals in the opposite direction--from the prosthetic arm to the brain.
