Photodynamic coatings kill bacteria on near-patient surfaces in intensive care units with low light intensities.

Background: Surfaces in close proximity to patients within hospitals may cause healthcare-associated infections. These surfaces are repositories for pathogens facilitating their transmission among staff and patients. Regular cleaning and disinfection of these surfaces provides only a temporary elimination of pathogens with inevitable recontamination.

Magnetic Mini-Mover Procedure for pectus excavatum IV: FDA sponsored multicenter trial.

Purpose: The Magnetic Mini-Mover Procedure (3MP) is a minimally invasive treatment for prepubertal patients with pectus excavatum. This multicenter trial sought to supplement safety and efficacy data from an earlier pilot trial.

Methods: Fifteen patients with pectus excavatum had a titanium-enclosed magnet implanted on the sternum.

A low-frequency versatile wireless power transfer technology for biomedical implants.

Implantable biomedical sensors and actuators are highly desired in modern medicine. In many cases, the implant's electrical power source profoundly determines its overall size and performance . The inductively coupled coil pair operating at the radio-frequency (RF) has been the primary method for wirelessly delivering electrical power to implants for the last three decades .

Magnetic mini-mover procedure for pectus excavatum III: safety and efficacy in a Food and Drug Administration-sponsored clinical trial.

Purpose: The magnetic mini-mover procedure (3MP) uses magnetic force to gradually remodel pectus excavatum deformity. A magnet is implanted on the sternum and coupled with an external magnetic brace. Under Investigational Device Exemption and Institutional Review Board approval, we performed a pilot study of safety, probable efficacy, and cost-effectiveness of this new treatment of an orphan disease using an implantable pediatric device.

Magnamosis II: Magnetic compression anastomosis for minimally invasive gastrojejunostomy and jejunojejunostomy.

Background: Previously we demonstrated the safety and patency of a magnetic compression anastomosis (magnamosis). We present the further development of this technique, with specific focus on optimizing device design for minimally invasive magnamosis.

Study Design: The magnamosis device was designed to incorporate 3 features: 2 convex-concave radially symmetric halves that magnetically self-align, a central channel for immediate patency, and specially engineered radial topography of the mating surfaces to promote gradual remodeling.
