A delivery device for a collapsible prosthetic heart valve, the delivery device including an inner shaft, a distal sheath disposed about a portion of the inner shaft and forming a compartment with the inner shaft, the compartment being adapted to receive the prosthetic heart valve, the inner shaft and the distal sheath being movable relative to one another, and a handle including a frame having a longitudinal axis, a proximal end and a distal end, the handle further including a deployment actuator and a hub, each of the deployment actuator and the hub being independently capable of opening and closing the compartment, the hub further including a hub actuator coupled to the inner shaft.

Transcatheter delivery system with wheel actuation

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

A delivery device for a collapsible prosthetic heart valve may include an operating handle and a catheter assembly. The handle may include a housing, a piston cylinder, a piston longitudinally slidable within the piston cylinder, the piston and the piston cylinder together defining at least one pressure chamber, a deployment actuator coupled to the housing and rotatable relative thereto, and a pneumatic switch adapted to provide a pressurized fluid to the pressure chamber to apply a longitudinal force to the piston. The catheter assembly may include a first shaft around which a valve-receiving compartment is defined, the first shaft being operatively connected to the housing, and a distal sheath operatively connected to the piston, the distal sheath being moveable between a closed condition covering the compartment and an open condition uncovering the compartment. Longitudinal movement of the piston may move the distal sheath between the closed and open conditions.

A delivery device for an implantable medical device includes an inner shaft with a device-carrying region, an outer shaft surrounding the inner shaft, a sheath at a distal end of the outer shaft, and a sleeve. The outer shaft is movable relative to the inner shaft from an advanced position in which the sheath surrounds the device-carrying region to a retracted position in which the sheath exposes the device-carrying region. The sheath includes a proximal structure having a cylindrical portion between first and second transition zones. The sleeve surrounds the outer shaft and is movable relative to the outer shaft from an advanced position in which a distal end portion of the sleeve surrounds the cylindrical portion to a retracted position in which the distal end portion of the sleeve is spaced proximally from the cylindrical portion.

Integrated sheath interface feature

A delivery device for a collapsible prosthetic heart valve may include an operating handle having a housing and a carriage movable relative to the housing, and a catheter assembly. The catheter assembly may have an inner shaft around which a compartment is defined, an outer shaft surrounding at least a portion of the inner shaft, a distal sheath fixedly connected to the outer shaft, and a spline tube surrounding at least a portion of the inner shaft. The spline tube may have thinner portions having a first maximum thickness in a radial direction of the inner shaft and thicker portions having a second maximum thickness in the radial direction that is greater than the first maximum thickness. The spline tube and the outer shaft may together define one or more channels that provide liquid communication between the operating handle and the compartment.

Catheter shaft construction for TAVR delivery systems

A guide wire configured for intravascular insertion includes a core wire having a flattened portion configured to allow the core wire to preferentially bend in at least one plane that passes through a longitudinal axis of the core wire. A distal most end of the flattened portion is spaced from a distal most end of the core wire. The guide wire may further include a sensor element configured to measure a physiological variable in a living body and a coil surrounding a portion of the core wire.

A delivery device for a collapsible prosthetic heart valve, the delivery device comprising an inner shaft, a distal sheath disposed about a portion of the inner shaft and forming a compartment with the inner shaft, the compartment adapted to receive the valve, the inner shaft and the distal sheath being slidable relative to one another, and a handle including a frame, a deployment actuator, a lever, and a hub, each of the deployment actuator, the lever, and the hub being independently capable of opening and closing the compartment, a resheathing lock configured to alert a user of a position of the distal sheath relative to the inner shaft and to impede movement of the distal sheath relative to the frame, and an indicator disposed on the frame and capable of showing an extent of deployment of the valve.

Transcatheter delivery system with two modes of actuation

A delivery device for a collapsible prosthetic heart valve includes an outer shaft having a first end and a second end, an inner shaft disposed inside the outer shaft and longitudinally movable relative to the outer shaft, and a distal sheath coupled to the inner shaft and movable with the inner shaft to selectively cover and uncover a compartment for housing the valve. The outer shaft includes a plurality of disks each having at least two hinges to allow articulation of adjacent disks relative to one another, and at least one rib for coupling the adjacent disks to one another.

Flexible catheter and methods of forming same

A delivery device for an implantable medical device includes an inner shaft extending in a longitudinal direction and an outer sheath adapted to surround at least a portion of the inner shaft, the outer sheath being slideable relative to the inner shaft in the longitudinal direction. A compartment defined between the inner shaft and the outer sheath is adapted to receive the medical device in an assembled condition. A retaining assembly positioned at one end of the compartment includes a first member rotatable with respect to the inner shaft, and a second member rotationally fixed with respect to the inner shaft. The medical device includes at least one retainer adapted to be received within at least one retainer slot of the first member. This arrangement enables the medical device to rotate within the compartment as the delivery device is advanced to an implantation site.
