摘要： An MRI-compatible catheter includes an elongated flexible shaft having opposite distal and proximal end portions. A handle is attached to the proximal end portion and includes an actuator in communication with the shaft distal end portion that is configured to articulate the shaft distal end portion. The distal end portion of the shaft may include an ablation tip and includes at least one RF tracking coil positioned adjacent the ablation tip that is electrically connected to an MRI scanner. The at least one RF tracking coil is electrically connected to a circuit that reduces coupling when the at least one RF tracking coil is exposed to an MRI environment. Each RF tracking coil is a 1-10 turn solenoid coil, and has a length along the longitudinal direction of the catheter of between about 0.25 mm and about 4 mm.

摘要： The systems include a display with a User Interface in communication with a circuit, the display is configured to display a patient model/map or model of target anatomical structure. The User Interface is configured to allow a user to select at least one target site (e.g., ablation site) on the model/map whereby scan planes for a corresponding location in 3-D space for the selected target ablation site are pre-set for future use. The circuit can be configured to automatically direct the MRI Scanner to use the pre-set scan planes to obtain MR image data when an intrabody device such as an ablation catheter is at the location that corresponds with the selected target site.

摘要： A ventricular apex connector for quick connection and disconnection of an inflow tube of a ventricular assist device, comprising a sewing ring, a cylindrical ring, gripping pins, a spring ring and a sealing O-ring is provided. The cylindrical ring defines two openings, diametrically opposed to each other, in its walls. Gripping pins, comprising rods with gripping pads, are placed in the openings in the cylindrical ring so that the gripping pads are at rest within the inner circumference of the cylindrical ring. The spring ring is placed around the cylindrical ring and the rods of the gripping pads, which extend out of the outer wall of the cylindrical ring, are welded to the spring ring. The gripping pins are thus biased towards each other by the force of the spring ring. When the spring ring is squeezed, at points away from the gripping pin connection points, the deformation of the spring ring causes the gripping pads to be pulled out towards the inner wall of the cylindrical ring. An inflow tube of a heart pump may then be inserted into the ventricular apex connector, and upon the release of the spring ring, the inflow tube is sealedly held within the ventricle of the heart. In an embodiment an adapter sleeve may be attached to the inflow tube. In a further embodiment, the inflow tube may include an inner sleeve that is slidably and rotatably mounted therein. The inflow tube may have a bend at an end.
