Stented prosthetic heart valve crimping tools and methods, and transcatheter delivery systems for delivering a crimped prosthetic heart valve. Methods of the present disclosure include crimping or compressing a stented prosthetic heart valve via spherical compression to a spherically compressed shape, and then delivering the so-shaped prosthesis to a target site. Delivery systems carrying a spherically-compressed prosthesis have a reduced length profile as compared to conventional, elongated configurations, providing increased maneuverability and positioning.

In one embodiment, the present invention includes an intramedullary osteosynthesis or arthrodesis implant including a central body, a first pair of legs extending from the central body to a pair of leg tips, and a second pair of legs extending from the central body, in a direction opposite the first pair of legs, to a pair of leg tips such that the central body, first pair of legs and second pair of legs are positioned alongside a longitudinal axis.

The invention relates to a device for use in the transcatheter treatment of mitral valve regurgitation, specifically a coaptation enhancement element for implantation across the valve; a system including the coaptation enhancement element and anchors for implantation; a system including the coaptation enhancement element, catheter and driver; and a method for transcatheter implantation of a coaptation element across a heart valve.

A mitral valve replacement device is adapted to be deployed at a mitral valve position in a human heart. The device has an atrial flange defining an atrial end of the device, a ventricular portion defining a ventricular end of the device, the ventricular portion having a height ranging between 2 mm to 15 mm, and an annulus support that is positioned between the atrial flange and the ventricular portion. The annulus support includes a ring of anchors extending radially therefrom, with an annular clipping space defined between the atrial flange and the ring of anchors. A plurality of leaflet holders positioned at the atrial end of the atrial flange, and a plurality of valve leaflets secured to the leaflet holders, and positioned inside the atrial flange at a location above the native annulus.

An apical pad for securing a prosthetic heart valve within a native valve annulus. The apical pad includes a first collar, a second collar and plurality of struts extending between the first collar and the second collar. The plurality of struts has a delivery condition in which the plurality of struts collectively form a first cross-section and a deployed condition in which the plurality of struts collectively form a second cross-section greater than the first cross-section. The apical pad may be coupled to a tether extending from a prosthetic heart valve and may transition from the delivery condition to the deployed condition by tensioning the tether.

A stent includes a first longitudinally extended cylinder having a C-shaped cross-section and a second longitudinally extended cylinder having a C-shaped cross-section. The first cylinder includes a plurality of first longitudinal struts and an array of first radial struts extending between the first longitudinal struts. The second cylinder includes a plurality of second longitudinal struts and an array of second radial struts extending between the second longitudinal struts. The first cylinder and the second cylinder are configured to form a dense mesh structure when assembled. When assembled, the second cylinder may be disposed in the first cylinder. The first cylinder may overlap with the second cylinder to form the dense mesh structure.

Delivery devices for a stented prosthetic heart valve. The delivery device includes a spindle, at least one cord, and a covering feature associated with the spindle for selectively covering at least a portion of a stented prosthetic heart valve tethered to the spindle in a delivery state. In some embodiments, the covering feature includes a tip mounted to the spindle. The tip can include an overhang region for selectively covering a portion of the stented prosthetic heart valve. In other embodiments, the tip can include a tip body and a compressible foam bumper. In yet other embodiments, the covering feature includes an outer sheath arranged to selectively cover the stented prosthetic heart valve. The outer sheath can be elastic and stretchable for recapturing a partially expanded prosthesis, for example by including one or more windows covered by a stretchable covering layer.

A heart valve anchor apparatus may include a body having a proximal portion and a distal portion. The body may include a first radially expandable portion at the proximal portion of the body, a second radially expandable portion at the distal portion of the body, and a root portion extending from the first radially expandable portion to the second radially expandable portion, the root portion having an outer extent. The first radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. The second radially expandable portion may be configured to self-expand to an outer extent greater than the outer extent of the root portion when radially unconstrained. In an unstressed configuration, the body may define a longitudinal centerline that extends away from a plane tangent to the root portion.

A medical device is disclosed and may have a spiral shape structure that can function as a stent, such as a flow diversion stent to treat aneurysms. The medical device may have a spiral shape structure that can function as an occlusive device, for instance to occlude aneurysms. The medical device may include a shape setting structure to selectively adjust the shape of the medical device.

This invention relates to the design and function of a compressible valve replacement prosthesis, collared or uncollared, which can be deployed into a beating heart without extracorporeal circulation using a transcatheter delivery system. The design as discussed focuses on the deployment of a device via a minimally invasive fashion and by way of example considers a minimally invasive surgical procedure preferably utilizing the intercostal or subxyphoid space for valve introduction. In order to accomplish this, the valve is formed in such a manner that it can be compressed to fit within a delivery system and secondarily ejected from the delivery system into the annulus of a target valve such as a mitral valve or tricuspid valve.
