Abstract: An electromagnetic immune tissue invasive system includes a primary device housing. The primary device housing having a control circuit therein. A shielding is formed around the primary device housing to shield the primary device housing and any circuits therein from electromagnetic interference. A lead system transmits and receives signals between the primary device housing. The lead system is either a fiber optic system or an electrically shielded electrical lead system.

Abstract: Devices and methods are disclosed for the treatment or repair of regurgitant cardiac valves, such as a mitral valve. An illustrative annuloplasty device can be placed in the coronary sinus to reshape the mitral valve and reduce mitral valve regurgitation. An improved protective device can be placed between the annuloplasty device and an underlying coronary artery to inhibit compression of the underlying coronary artery by the annuloplasty device in the coronary sinus. In addition, the protective device can inhibit compression of the coronary artery from inside the heart, such as from a prosthetic mitral valve that exerts radially outward pressure toward the coronary artery. The annuloplasty device can also create an artificial inner ridge or retaining feature projecting into the native mitral valve region to help secure a prosthetic mitral valve.

Abstract: A medical device enables effective magnetic resonance imaging inside a lumen of a medical device. The medical device includes a plurality of conductive traces formed on a substrate. The conductive traces form an inductive-capacitance circuit or a resistive-inductive-capacitance circuit. The inductive-capacitance circuit or resistive-inductive-capacitance circuit is tuned to a frequency associated with magnetic resonance imaging, an operating frequency associated with a magnetic resonance imaging scanner, a harmonic of an operating frequency associated with a magnetic resonance imaging scanner, or a sub-harmonic of an operating frequency associated with a magnetic resonance imaging scanner.

Abstract: An electromagnetic interference immune defibrillator lead has a first electromagnetic insulating layer. A first layer is formed on the first electromagnetic insulating layer, the first layer having a plurality of first conductive rings composed of first conductive material, each first conductive ring being separated by first insulating material. A second electromagnetic insulating layer is formed on the first layer. A second layer is, formed on the second electromagnetic insulating layer, the second layer having a plurality of second conductive rings composed of second conductive material, each second conductive ring being separated by second insulating material. A third electromagnetic insulating layer is formed on the second layer. The second conductive rings of second conductive material are positioned such that a second conductive ring overlaps a portion of a first conductive ring and overlaps a portion of a second conductive ring, the second conductive ring being adjacent to the first conductive ring. The second electromagnetically insulating layer is composed of a self-healing dielectric material.
