Abstract: A catheter includes an elongated body, a distal assembly with a shape-memory member defining a generally circular form, and a control handle adapted to actuate a deflection puller wire for deflecting a portion of the elongated body, and a contraction wire for contracting the generally circular form. The generally circular form which carries at least one ring electrode has an off-edge configuration relative to the elongated body such that a longitudinal axis of the elongated body does not intersect the circumference of the circular form and the generally circular form spirals about the longitudinal axis of the elongated body. Moreover, the circular form can have an on-axis configuration such that the longitudinal axis of the elongated body is axially aligned with a central longitudinal axis of the circular form, or an off-axis configuration such that these axes are axially offset from each other. In a more detailed embodiment, the catheter has a distal assembly with a helical form or a crescent form carrying a plurality of irrigated ablation ring electrodes and a plurality of smaller ring electrodes adapted for impedance recording or PV potential recording. A support member with shape memory extends through the distal assembly to provide the helical or crescent form. The support member has a varying stiffness along its length, for example, a decreasing stiffness toward a distal end of the support member. The support member can also be hollow so that it can receive a mandrel whose stiffness is greater than that of the support member.

Abstract: Tissue shaping methods and devices are provided for reinforcing and/or remodeling heart valves. In certain embodiments, magnetic tissue shaping devices are implanted in tissue adjacent heart valve leaflets. The devices are mutually attractive or repulsive so as to remodel the heart tissue and improve heart valve function. In certain other embodiments, one or more tissue shaping devices including shape memory material are implanted in a patient's body within or on tissue adjacent a heart valve leaflet. The shape memory material can be activated within the patient in a less invasive or non-invasive manner, such as by applying energy percutaneously or external to the patient's body. The shape memory tissue shaping devices are implanted in a first configuration and then activated to remember a second configuration that displaces tissue so as to remodel the heart valve geometry and improve heart valve function. In certain other embodiments, a brace is crimped to the base of a heart valve leaflet to support the leaflet and improve valve closure.

Abstract: Methods and devices are provided for support of a body structure. The devices can be adjusted within the body of a patient in a minimally invasive or non-invasive manner such as by applying energy percutaneously or external to the patient's body. The energy may include, for example, acoustic energy, radio frequency energy, light energy and magnetic energy. Thus, as the body structure changes size and/or shape, the size and/or shape of the annuloplasty rings can be adjusted to provide continued reinforcement. In certain embodiments, the devices include an anterior portion, a posterior portion and two lateral portions corresponding to intersections of the anterior portion and the posterior portion. The devices have a first shape in a first configuration and a second shape in a second configuration and are configured to transform from the first configuration to the second configuration in response to an activation energy applied thereto. The transformation is configured to reduce a distance between the anterior portion and the posterior portion more than a distance between the two lateral portions.

Abstract: An annuloplasty device for supporting a heart valve is described. The system includes a body member having a proximal end, a distal end, and a length extending therebetween. The body member is configured to be implanted within a patient's heart at or near a base of a heart valve. The body member includes a first portion, including a shape memory material and being transformable from a first configuration to a second configuration in response to an activation energy. The body member also includes a second portion coupled to the first portion. The second portion includes a magnetic material that is responsive to a magnetic field. When in position at or near the base of the heart valve and when the body member transforms from the first configuration to the second configuration, the body member reshapes a tissue of the heart so as to exert a force on the heart valve base.

Abstract: The present invention includes a body implantable lead having a multi-polar proximal connector, at least a first conductor coupled to at least one stimulating electrode, a sensor for sensing at least one physiologic parameter of the body, and a second and a third conductor coupled to the sensor. The sensor is hermetically sealed in a D-shaped housing. Sensor components are mounted onto a microelectronic substrate which is advantageously placed on an inner flat portion of the D-shaped housing. End caps having glass frit sealing rings are used to seal the ends of the shell. A hermetic seal is easily achieved by heating the glass frit such that the glass frit reflows between the end caps and the shell. Advantageously, the sensor terminals are sized to fit snugly within a narrow bore of the end cap which is then welded closed. The D-shaped sensor is placed on a carrier having at least two lumens. At least the first and second conductors pass through the lumens for connection with the stimulating electrode and the distal end of the sensor. Advantageously, the D-shaped housing reduces the area that needs to be hermetically sealed by more than half, and thus reduces the overall diameter of the lead. Advantageously, the conductors coupled to the sensor function independently from the stimulation conductors so that interference with basic operation of the pacemaker is prevented.
