Abstract: Devices and methods are disclosed for the treatment or repair of regurgitant cardiac valves, such as a mitral valve and/or tricuspid valve. An illustrative annuloplasty device can be placed in the coronary sinus to reshape the mitral valve and reduce mitral valve regurgitation as well as tricuspid regurgitation. The disclosure also provides improved techniques for cardiac pacing.

Abstract: A voltage compensation unit reduces the effects of induced voltages upon a device having a single wire line. The single wire line has balanced characteristic impedance. The voltage compensation unit includes a tunable compensation circuit connected to the wire line. The tunable compensation circuit applies supplemental impedance to the wire line. The supplemental impedance causes the characteristic impedance of the wire line to become unbalanced, thereby reducing the effects of induced voltages caused by changing magnetic fields.

Abstract: An implantable medical assist device includes a medical device. The medical device has a housing and electronics contained therein. A lead provides an electrical path to or from the electronics within the medical device. A resonance tuning module is located in the housing and is connected to the lead. The resonance tuning module includes a control circuit for determining a resonant frequency of the implantable medical assist device and an adjustable impedance circuit to change the combined resonant frequency of the medical device and lead.

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.
