The electrophysiology team at the Montreal Heart Institute (MHI) recently performed the first implantation of a new type of cardiac pacemaker (Accent RF) in Canada. This landmark procedure was carried out on October 22, 2009 by Drs. Bernard Thibault and Peter Guerra. Both are cardiologists, electrophysiologists at the MHI and professors at the Université de Montréal. The Accent RF(TM) pacemaker uses wireless technology and is intended for people with bradycardia, an abnormally slow heart rate. The patient responded favourably to the procedure, and four additional implantations have since been performed, again with successful outcomes. http://www.physorg.com/news180081429.html Medicine & Health Tue, 15 Dec 2009 06:50:04 EST news180081429 (PhysOrg.com) -- The first year to two years of life is a critical time for hearing impaired children and their language development. Whilst young babies with hearing difficulties can now be fitted with cochlear implants, accurately assessing the effectiveness of the implants does present challenges prior to their development of language skills. http://www.physorg.com/news179764984.html Medicine & Health Fri, 11 Dec 2009 15:00:01 EST news179764984 A novel technology involving use of stem cells, developed by Hebrew University of Jerusalem researchers, has been applied to provide better and rapid healing for patients suffering from complicated bone fractures. http://www.physorg.com/news178802935.html Medicine & Health Mon, 30 Nov 2009 11:50:02 EST news178802935 Malaysian wildlife authorities are using electronic implants to keep track of orangutans in a bid to protect the endangered apes after they are freed into the wild, an official said Tuesday. http://www.physorg.com/news178296802.html Biology Tue, 24 Nov 2009 15:20:01 EST news178296802 As many as 10 million people around the world suffer from cataracts.

In August, the 6-year-old had surgery to place a cochlear implant in her right ear. Now Ava plays with toys while Ginger Stickney describes to Dave and Gabrielle Martin the tests that will gauge how their daughter`s auditory nerve is responding to the implant. But first Stickney must activate the device that could restore function to Ava`s right ear - an ability lost years ago due to a congenital inner-ear defect that`s also destroying the hearing in her left ear. http://www.physorg.com/news176659178.html Medicine & Health Thu, 05 Nov 2009 18:00:01 EST news176659178 Radiation dose delivered to the prostate and nearby organs in every brachytherapy procedure should be carefully analyzed using post-implant CT or MRI and uniformly documented in every patient, according to a new guideline co-authored by Yan Yu, Ph.D., director of Medical Physics in the department of Radiation Oncology at Thomas Jefferson University. http://www.physorg.com/news176449414.html Medicine & Health Tue, 03 Nov 2009 06:00:01 EST news176449414 Animal research is suggesting new ways to aid recovery after spinal cord injury.

However, artificial catheters known as "stents" can remediate this problem. Stents are medical implants which reopen narrowed bile ducts to allow the outflow of bile. However, bacteria colonize these catheters forming dense communities, so-called biofilms. Inside these biofilms, bacteria are not only protected from the immune response initiated by the host but also from antibiotics. http://www.physorg.com/news161257134.html Biology Mon, 11 May 2009 10:42:06 EST news161257134 Despite the common perception that total hip replacements last about 10 years, researchers at Rush University Medical Center have found that the devices are extremely durable, even 20 years after surgery. http://www.physorg.com/news160405493.html Medicine & Health Fri, 01 May 2009 14:05:21 EST news160405493 (AP) -- Wisconsin could become the first state requiring private insurance companies to cover cochlear implants for children with severe hearing problems.
