Abstract: A delivery device includes a handle, a central elongate member extending from the handle, a sheath configured to slide over and relative to the central elongate member, a distal tether retainer at a distal end of the central elongate member, a proximal tether restraining mechanism positioned along the central elongate member distal of the handle and proximal of the distal tether retainer, and a plurality of tethers. The tethers are configured to extend from the proximal tether restraining mechanism to the distal tether retainer.

Abstract: A delivery device includes a central elongate structure, a sheath, a plurality of tethers extending through the central elongate structure configured to hold a cardiac valve, a cutting mechanism, a handle, and a control. The sheath is configured to slide over the central elongate structure. The cutting mechanism is configured to cut the tethers upon activation to release the cardiac valve. The handle is connected to the central elongate structure. The control on the handle is configured to activate the cutting mechanism.

Abstract: A delivery device includes a central elongate structure including an annular member at the distal end, a sheath, a plurality of tethers extending through the central elongate structure, a handle, and a control on the handle. The handle is connected to the elongate structure, the sheath, and the plurality of tether. The control is configured to move the sheath proximally and distally over the central elongate structure. The annular member includes a plurality of pockets extending radially therearound. Each tether includes a feature on a distal end thereof configured to fit within a pocket of the plurality of pockets to hold the tether in place.

Abstract: The invention comprises a virtual window system that creates a visual coherency between the image of the patient and his or her anatomy and the patient by aligning the image of the patient anatomy on the display to the patient and presenting the image to the user that feels as if the user is looking directly into the patient through the display. The invention is designed to also display medical devices, such as a minimally invasive tool. The system substantially unifies the coordinate systems of the patient, the medical device, the display, and the physician's hands. The invention creates a visual coherency between the motion of the medical device in the image and the motion of the physician's hands manipulating the device. This invention also creates a visual coherency between the motion of the image in the display and of that display.

Abstract: An image display system is provided comprised of a virtual window system that creates a visual coherency between the patient's anatomical images and the actual patient by aligning the image on the display to the patient and then presenting the image to the user in a way that feels as if the user is looking directly into the patient through the display. The image shown within the image display system is dependent upon the position of the image display apparatus and the position of the user so that the display orientation of the image may be biased slightly toward the user to improve ergonomics and usability.

Abstract: A method of manipulating an elongate member in at least two degrees of freedom includes holding an elongate member between two rotary members that define respective rotational axes, the elongate member having a flexible proximal portion, a distal rigid needle attached to the proximal portion, and an operative element for delivering energy, the needle having a distal port, actuating at least one of the rotary members in a rotational direction about its rotational axis to generate a corresponding linear motion of the elongate member along a longitudinal axis of the elongate member, and actuating at least one of the rotary members in a linear direction along its rotational axis to generate a corresponding rotational motion of the elongate member about the longitudinal axis of the elongate member.
