Synthetic biology is seeing rapid advances, but the medical applications have thus far remained largely elusive. But now researchers from the Wyss Institute for Biologically Inspired Engineering at Harvard University and Harvard Medical School (HMS) have developed a tool that can track specific populations of bacteria in the gut of living organisms and document population changes over time.

The routine application of medical device technology to neurological indications beyond pain remains challenging in all but the most severe patients. Micro-cap Neuronetics Inc. is aiming to change all that with its Neurostar transcranial magnetic stimulation (TMS) system that is noninvasive and used in the physician's office.

Arm and hand prosthetics have long been the focus for researchers aiming to offer sensation as well as more precise and easily controlled movement by connecting patient nerves to sensors in the prosthetic. But now that effort has been extended to leg prosthetics as well.

Radiation reduction during imaging procedures is a top priority for hospitals and health care providers. Startup Controlrad Inc. has raised a $15 million series B round to market its Trace mobile C-arm radiation reduction technology for use during fluoroscopically guided procedures. That has already been FDA cleared.

SAN FRANCISCO – Abbott Laboratories expects that its self-expanding transcatheter aortic valve replacement (TAVR) system Portico will be able to become a top competitive product. A pivotal trial of Portico has found that the implant is noninferior to current FDA-approved TAVR systems that are marketed in the U.S. The results from the 750-patient, randomized trial were presented here last week at the Transcatheter Cardiovascular Therapeutics (TCT) conference.

SAN FRANCISCO – As the transcatheter aortic valve replacement (TAVR) field matures, it is becoming increasingly difficult to develop a new implant that can distinguish itself vs. competitors. The incremental benefits are narrowing rapidly, making it tough to distinguish new iterations from one another using standard, randomized trials.

SAN FRANCISCO – Mitraclip from Abbott Park, Ill.-based Abbott Laboratories, has long been the only minimally invasive mitral valve repair device that's approved by the FDA. Edwards Lifesciences Corp., of Irvine, Calif., aims to challenge that dominance with its Pascal. This week at the Transcatheter Cardiovascular Therapeutics (TCT) conference, positive one-year data from the small CLASP study on Pascal were presented, offering a further glimpse of data for comparison.

SAN FRANCISCO – The accelerating confluence of information technology and medical devices is transforming the latter into a true embodiment of med tech. That was the conclusion of early keynote sessions at the Transcatheter Cardiovascular Therapeutics (TCT) that began here yesterday.
