The present disclosure is directed to an Inferior Vena Cava (IVC) filter apparatus and related methods. The IVC filter apparatus comprises a body having a proximal hook thereon. A plurality of filter legs extends away from the proximal hook. A distal hook is position interior to at least a portion of the plurality of legs.

Valve holders and introducers for delivering a prosthetic heart valve to an implant site are configured to facilitate insertion of prosthetic valves through small incisions or access sites on a patient's body. The valve holders can also be configured to reduce or eliminate the occurrence of suture looping or other damage to the prosthetic valve during implantation. A valve holder according to embodiments of the invention includes features that reduce or eliminate mistakes during implantation of the prosthetic valves, such as a handle that prevents implantation of the valve prior to proper deployment or adjustment of the holder. An introducer is provided which can facilitate temporary deformation of a nitinol prosthetic valve to pass between adjacent ribs of a patient without rib spreading. Valves are provided having a wireform and stiffener band made of materials that exhibit superelastic properties. Valve holders, introducers, and valves according to the various embodiments can be used in minimally invasive procedures, such as thoracotomy procedures.

Mitral valve prolapse and mitral regurgitation can be treating by implanting in the mitral annulus a transvalvular intraannular band. The band has a first end, a first anchoring portion located proximate the first end, a second end, a second anchoring portion located proximate the second end, and a central portion. The central portion is positioned so that it extends transversely across a coaptive edge formed by the closure of the mitral valve leaflets. The band may be implanted via translumenal access or via thoracotomy.

In particular, some embodiments provide shunts having a plurality of individually actuatable flow control elements that can control the flow of fluid through associated ports and/or flow lumens. For example, each individually actuatable flow control element can be actuated to modify a flow of a corresponding port and/or flow lumen. The individually actuatable flow control elements may be actuated along a given actuation axis. A flow control assembly may include a plurality of flow control elements arranged about a collection region. Accordingly, the shunts described herein can be manipulated into a variety of configurations that provide different drainage rates based on a degree to which the ports and/or flow lumens are blocked or unblocked, therefore providing a titratable glaucoma therapy for draining aqueous from the anterior chamber of the eye.

Medical devices utilizing shape memory alloys and associated methods are disclosed herein. One aspect of the present technology, for example, is directed toward a treatment element configured to be positioned within a body lumen and coupled to an energy source. At least a portion of the treatment element may be made of a shape memory alloy, and wherein application of thermal energy to the treatment element from the energy source transforms the treatment element from the martensitic state to the austenitic state in which the treatment element is configured to cut, ablate, resect, and/or cauterize tissue.

Implant (10) for a heart valve comprising two leaflets, particularly a mitral valve (MV), the implant (10) comprising: a clamp (11) comprising a body (13) and a jaw (14) rotationally hinged with the body (13) to pivot between an open position and a closed position in which the body (13) and the jaw (14) are able to clamp a first leaflet among the heart valve leaflets, so as to attach the implant (10) onto the first leaflet, a movement device (41, 42) comprising a pusher element (41), the movement device being configured to move the jaw (14) relative to the body (13) from the open position to the closed position or vice versa, when the pusher element (41) is pushed by a rod (101), and a balloon (12) attached to the clamp (11) and configured to close at least partially an open portion (O1) remaining between the heart valve (MV) leaflets during systole, when the implant (10) is attached to the first leaflet, so as to limit a reflux of blood through said open portion (O1) remaining during systole.

An atrioventricular valve clamping device and an atrioventricular valve clamping system are provided in the disclosure. The atrioventricular valve clamping device includes a support member, an occluding member, and a clamping member. A direction of a central axis of the occluding member is regarded as a Z-direction, a direction parallel to a width direction of the clamping member and perpendicular to the Z-direction is regarded as a Y-direction, and a direction perpendicular to the Y-direction and the Z-direction is regarded as an X-direction. The support member has a length in the Z-direction. The occluding member is sleeved on the support member in the Z-direction. The clamping member is disposed outside the occluding member and configured to be unfolded or folded relative to the occluding member. The occluding member is resilient and has a three-dimensional shape.

A prosthetic spacer assembly includes a spacer, a first anchor, and a second anchor. The first anchor and the second anchor are each connected to the spacer. The first anchor curves around the spacer when viewed from an upstream end. The second anchor curves around the spacer when viewed from the upstream end.

An implantable artificial bronchus including a body having a proximal upper opening and a distal lower opening. The distal lower opening being in fluid communication with the proximal upper opening, and the body at least partially tapering along a length toward the distal lower opening. The body having a plurality of side openings configured to allow air to enter into and exit the implantable artificial bronchus through the body. A length of the body is greater than 4 times the size of a largest diameter of the body, and the diameter of the proximal upper opening is larger than a diameter of the distal lower opening.

An adjustable artificial chordae tendineae fixing assembly includes an occlusion device and an adjusting rod which are both a hollow structure allowing the artificial chordae tendineae to pass through. The occlusion device is configured to be clamped on the interventricular septum. The occlusion device is provided with a switch adjusting device which controls the artificial chordae tendineae to move and to be fixed. The adjusting rod is connected to the occlusion device, and is capable of repeatedly adjusting the switch adjusting device on the occlusion device. The artificial chordae tendineae fixing assembly can fix the artificial chordae tendineae on the interventricular septum, and can also overcome the problem of unsuitable length of the artificial chordae tendineae in most of patients after the procedure due to cardiac changes. The artificial chordae tendineae is retained at the skin puncture point for a short time.
