Boston Scientific faces stinging setback for vagus nerve stimulation device in mid-stage trial

Boston Scientific is facing a stinging setback in the highly competitive neuromodulation field as the company's vagus nerve stimulation (VNS) device failed to improve cardiac function in a recent mid-stage clinical trial.

Dime-sized device can separate healthy and cancerous cells

MIT scientists have developed a dime-sized microfluidic device that can sort rare cancer cells from healthy ones using sound waves--an innovation that could have applications for cancer diagnosis, drug discovery and clinical research.

Transcranial magnetic stimulation can improve memory, study shows

Researchers used transcranial magnetic stimulation to stimulate the hippocampus region in the brain. This resulted in increased connectivity in related regions and improved memory that persisted in healthy volunteers for more than 24 hours after stimulation, according to a study in the latest issue of the journal Science.

New imaging system uses biomarker to guide brain cancer surgery

Brain surgeons have long relied on a pathology analysis to determine if they have completely removed a tumor. This can be a time-consuming and inaccurate process. Results of a study for a new imaging system that detects a molecular marker found in brain gliomas suggest it could improve upon that surgical practice.

Medtronic launches clinical trial of AdaptivCRT physiologic pacing algorithm

Medtronic announced an international clinical trial comparing standard cardiac resynchronization therapy against CRT with the AdaptivCRT physiologic pacing algorithm that makes automatic adjustments to the therapy.

ReShape targets U.S. approval as EU study shows major weight loss

ReShape Medical revealed the first postapproval data from the EU for its nonsurgical, balloon-based weight-loss system: 42% of excess weight loss on average with a variance of 23%. But the company cautions that because of the different way the trials are designed, it won't have similar results when it releases pivotal U.S. trial data in November.

White House spotlights need for electrical implants to treat inflammatory and neurological diseases

President Obama highlighted a $78.9 million BRAIN Initiative project to improve service members' and veterans' health through the development of nano-scale electrical implants to modulate nerve signaling and record health biomarkers.

Study finds robotic prostate removal surgery results in faster recovery times

A study of robotic laparoscopic radical prostatectomy found that though it is more expensive than traditional prostate removal surgery and technically more demanding, it is also associated with a quicker recovery of continence and shorter operating time.

Researchers develop implant/app combo to monitor glaucoma in aging eyes

Researchers are developing an implantable sensor for glaucoma that allows intraocular pressure to be read by a smartphone camera. Diagnosis and monitoring now relies on a trip to the ophthalmologist and a reading of intraocular pressure that can vary widely. The implant/smartphone combination is expected to allow at-home monitoring and a series of readings that could improve diagnosis and monitoring of glaucoma patients.

Cardiologists overstate benefits of stenting, patients fail to recall their precautions

When the heart is at risk, patients are eager to listen to their doctor's recommendations. But three studies have found that many cardiologists oversell the benefits of percutaneous coronary interventions involving stenting, and patients often fail to remember the doctor's precautions about the procedure.
