A delivery device for a collapsible prosthetic heart valve includes an inner shaft, an outer shaft, and a distal sheath. The distal sheath may be disposed distal to the outer shaft and about a portion of the inner shaft to form a compartment with the inner shaft, the compartment being sized to receive the prosthetic heart valve in a collapsed condition. The inner shaft and the distal sheath may be movable relative to one another. The delivery device may also include a tube member and an outer sleeve overlying the tube member. The tube member may be configured to rotate or twist upon axial movement of the outer sleeve with respect to the tube member, the rotation or twisting of the tube member configured to rotate the prosthetic heart valve when the prosthetic heart valve is received within the compartment in the collapsed condition.

A delivery device for a collapsible prosthetic heart valve includes an inner shaft, an outer shaft, and a distal sheath. The distal sheath may be disposed distal to the outer shaft and about a portion of the inner shaft to form a compartment with the inner shaft. The compartment may be sized to receive the prosthetic heart valve. The inner shaft and the distal sheath may be movable relative to one another. A spine may extend along the outer shaft, the spine biasing the outer shaft so that the outer shaft tends to bend in a pre-determined direction.

Passive alignment of commissures in prosthetic heart valve implantation

An implantable delivery system has an inner shaft () with a device-carrying region () and an outer shaft () surrounding the inner shaft. A sheath () at a distal end of the outer shaft covers the device-carrying region when the outer shaft is in an advanced position. A sleeve () surrounding the outer shaft is in proximity to the sheath when the sleeve is in an advanced position. After insertion, the sleeve is retracted to increase flexibility of the distal end of the device. A handle () includes a control element for retracting the outer shaft and sheath relative to the inner shaft to release the implantable device. The sleeve may be fixed to the body of the handle when the sleeve is retracted. Engagement between the sleeve and an introducer at the insertion site can stabilize the handle and inner shaft against movement relative to the patient during retraction of the outer shaft.

Systems and methods for device implantation

A transcatheter valve delivery system includes a longitudinal member extending between a proximal end and a distal end, and having a compartment adjacent the distal end for holding a medical device in a collapsed condition. An alignment element is connected to the longitudinal member and is movable relative to the longitudinal member between a stowed position and a deployed position. In the deployed position, the alignment element is configured to urge against an anatomical surface to position the longitudinal member at a desired location relative to the anatomical surface.

A steerable guide wire includes a core wire having a proximal end and a distal end. A braided filament is affixed to the distal end of the core wire. An outer coil surrounds at least a portion of the core wire and the braided filament. A proximal end of the braided filament is secured to a distal end of the coil. By locating the braided filament in the distal tip portion of the guide wire, a guide wire is provided that is highly flexible, has a high degree of tensile integrity, and is highly steerable, even in tortuous vasculature. Filter and balloon catheters having braided filaments at the distal end are also described.

A tool holder having two distinct phases, a first phase in which the tool is held in an interference fit with sufficient mechanical interaction between the two for the tool to be rotated at high speed and perform its intended purpose on a workpiece, and a second phase in which the tool is sufficiently released from the interference fit to be rapidly removed from the holder (as by an automated apparatus).
