A delivery device for a collapsible medical device may include a handle and a delivery assembly having a compartment for receiving the medical device. A catheter member may extend from the handle to the delivery assembly. The catheter member may have a first portion with a first compliance value and a second portion with a second compliance value different from the first compliance value. An internally threaded member may be fixedly connected to the delivery assembly. An externally threaded member may have a first portion operatively connected to the actuation member and a second portion threadedly coupled to the internally threaded member so that manipulation of the actuation member causes axial movement of the compartment relative to the catheter member.

A distractible intervertebral implant configured to be inserted in an insertion direction into an intervertebral space that is defined between a first vertebral body and a second vertebral body is disclosed. The implant may include a first body and a second body. The first body may define an outer surface that is configured to engage the first vertebral body, and an opposing inner surface that defines a rail. The second body may define an outer surface that is configured to engage the second vertebral body, and an inner surface that defines a recess configured to receive the rail of the first body. The second body moves in a vertical direction toward the second vertebral body as the second body is slid over the first body and the rail is received in the recess.

A stent comprising: two or more stent sections; one or more rods extending between the two or more stent sections; wherein one the one or more rods is fixedly connected to a fixed anchor that is connected to a first of the two or more stent sections, and a second of the two or more of stent sections are movable connected to one of the one or more rods by a movable anchor; and wherein the stent supports an opening of an anatomical passageway.

A modular prosthetic valve device for implantation in a patient and a system for and method of delivering such a modular valve device and assembling it in vivo are disclosed. The valve device is designed as two or more modules to be delivered unassembled, spatially separate, and combined into an assembled valve device in the body at or near the site of implantation. The valve device of the invention is deliverable as modules, providing a smaller delivery diameter than pre-assembled percutaneous valves, permitting use of a delivery device of reduced diameter, and increasing the flexibility of the valve device during delivery, compared to percutaneous valve devices in the art. The modules of the valve device may be connected by pull wires for delivery sequentially, and then assembled by remote manipulation using the pull wires. Various locking mechanisms are provided for attaching the device modules together.

A transport device comprises a transport tube that extends from a rear end of a medical device. The transport tube has a double tube structure comprising an inner tube and an outer tube. The inner tube projects from a distal end part of the outer tube, and a distal end part of the inner tube is connected to the medical device. The outer tube and the inner tube are firmly fixed at a proximal end part of the outer tube.

Systems for mitral valve repair are disclosed where one or more mitral valve interventional devices may be advanced intravascularly into the heart of a patient and deployed upon or along the mitral valve to stabilize the valve leaflets. The interventional device may also facilitate the placement or anchoring of a prosthetic mitral valve implant. The interventional device may generally comprise a distal set of arms pivotably and/or rotating coupled to a proximal set of arms which are also pivotably and/or rotating coupled. The distal set of arms may be advanced past the catheter opening to a subannular position (e.g., below the mitral valve) and reconfigured from a low-profile delivery configuration to a deployed securement configuration. The proximal arm members may then be deployed such that the distal and proximal arm members may grip the leaflets between the two sets of arms to stabilize the leaflets.

A distractible intervertebral implant configured to be inserted in an insertion direction into an intervertebral space that is defined between a first vertebral body and a second vertebral body is disclosed. The implant may include a first body and a second body. The first body may define an outer surface that is configured to engage the first vertebral body, and an opposing inner surface that defines a rail. The second body may define an outer surface that is configured to engage the second vertebral body, and an inner surface that defines a recess configured to receive the rail of the first body. The second body moves in a vertical direction toward the second vertebral body as the second body is slid over the first body and the rail is received in the recess.

An anchor anchors a therapeutic device having an elongated body within a body lumen. The anchor includes a fixation member carried on the device which is adjustable from a first configuration that permits placement of the device in the body lumen to a second configuration that anchors the device within the body lumen. The anchor further includes a lock that locks the fixation member in the second configuration. The fixation member may be locked in any one of a plurality of intermediate points between the first configuration and a maximum second configuration.

A spinal implant has a proximal region and a distal region, and includes an upper body and a lower body each having inner surfaces disposed in opposed relation relative to each other. A proximal adjustment assembly is disposed between the upper and lower bodies at the proximal region of the spinal implant and is adjustably coupled to the upper and lower bodies, and a distal adjustment assembly is disposed between the upper and lower bodies at the distal region of the spinal implant and is adjustably coupled to the upper and lower bodies. The proximal and distal adjustment assemblies are independently movable with respect to each other to change a vertical height of at least one of the proximal region or the distal region of the spinal implant.

An implant with an open-worked, hollow cylindrical main structure composed of a multiplicity of crosspieces, wherein the implant adopts a compressed state and an expanded state. So as to achieve a greater level of radial rigidity and an increased collapse pressure in the expanded state compared to conventional implants, wherein the deliverability is not adversely affected at the same time, the density of the crosspieces in the expanded state is greater than the density of the crosspieces in the compressed state, at least in one portion of the implant. The invention further provides a system including a catheter with a balloon and an implant of the type disclosed above.
