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(More)
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(More)
BACKGROUND/PURPOSE Correction of pectus excavatum (PE) results in measurable improvement in lung capacity and cardiac performance as well as improved appearance and self-image. The Nuss and modified Ravitch approaches attempt to correct the chest wall deformity by forcing the sternum forward in 1 step and holding it in place using a metal strut. The initial(More)
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(More)
Implantable biomedical actuators are highly desired in modern medicine. However, how to power up these biomedical implants remains a challenge since most of them need more than several hundreds mW of power. The air-core based radio-frequency transformer (two face-to-face inductive coils) has been the only non-toxic and non-invasive power source for implants(More)
Failure Mode Effect Analysis (FMEA) offers a prospective approach to reducing the risk associated with health care delivery. Beginning in February, 2002, an interdisciplinary team of fifteen individuals, including end-users, conducted an FMEA for the use of infusion pumps at UCSF Medical Center. The use of infusion pumps was identified as the area of(More)
PURPOSE The Magnetic Mini-Mover Procedure (3MP) uses a magnetic implant coupled with an external magnet to generate force sufficient to gradually remodel pectus excavatum deformities. This is an interim report of the evolution of the 3MP during a Food and Drug Administration-approved clinical trial. METHODS After obtaining Institutional Review Board(More)
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. Externally, patients wore(More)
