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.

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.

The head fixation frame includes a pair of upwardly extending spaced-apart arms defining a free space therebetween. At least one upper head fixation member extends from each of the respective arms of the head fixation frame, with each upper head fixation member adjustable relative to the head fixation frame and adapted to engage a patient's head within the free space of the head fixation frame. The lower head fixation members extend from the head fixation frame between the pair of arms, with each member adjustable relative to the head fixation frame and adapted to engage an underside of the patient's head within the free space of the head fixation frame. The at least one drive mechanism is in communication with the lower head fixation members, and is externally accessible so as to allow a user to be able to directly or indirectly advance and/or retract the lower head fixation members while the patient's head resides in the free space of the head fixation frame.
