An apparatus for collapsing a prosthetic heart valve and retrieving the prosthetic heart valve from a native heart valve annulus includes a delivery tube having a lumen therethrough and a retrieval device extendable from the lumen. The retrieval device includes a first shaft including a plurality of first arms selectively moveable between a collapsed condition and an expanded condition, and a second shaft slidable relative to the first shaft, the second shaft including a plurality of second arms selectively moveable between a collapsed condition and an expanded condition. The first and second arms in the expanded condition grasp portions of the prosthetic heart valve, and in the collapsed condition collapse the prosthetic heart valve for removal through the delivery tube.

A prosthetic heart valve includes a self-expanding wire frame body, a valve disposed in the body, a leaflet clip coupled to the body, and a control element operably coupled to the leaflet clip. The body has a proximal end and a distal end. The leaflet clip is configured to be transitioned between a first configuration in which the prosthetic valve can be inserted into a heart, and a second configuration in which the leaflet clip is disposed to capture a native valve leaflet between the leaflet clip and the wire frame body when the body is disposed in a native annulus of an atrioventricular valve of a heart. The control element extends from the leaflet clip through a ventricle of the heart and out a wall of the ventricle to allow a user to transition the leaflet clip from its first configuration to its second configuration.

Medical devices and methods for making and using a medical device are disclosed. An example medical device may include an implantable medical device. The implantable medical device may include a stent having a covered portion and an uncovered portion. The covered portion may be releasably attached to the uncovered portion. A cover member may be disposed along the covered portion. The uncovered portion may include a release tab that is designed to release the uncovered portion from the covered portion. A removal member may be coupled to the covered portion for aiding in the removal of the covered portion from an implantation site.

Funnel-trap type devices made of shape-set (e.g., heatset) braid for delivery and/or retrieval of Inferior Vena Cava (IVC) filters or other medical devices are described. Delivery and/or retrieval devices, kits in which they are included, methods of use and methods of manufacture are all contemplated herein.

A stent graft delivery device includes a handle body, a distal handle, a proximal handle, a guidewire lumen, a nose cone, a rigid outer catheter, a graft push lumen, a sheath lumen, an inner sheath and a locking ring. The locking ring is switchable between an advancement position and a delivery position. The stent graft delivery device is employed in methods for endovascular delivery of stent grafts.

A thrombectomy system and method of extraction of thrombus are disclosed. The thrombectomy system comprises a delivery catheter; an aspiration catheter, comprising an aspiration funnel, configured to be movably disposed within the delivery catheter in a retracted position and at least partially outside the delivery catheter in an extended and expanded position, the funnel comprising a non-permeable covering, the funnel being configured to adapt its shape and length to a surrounding blood vessel such that the funnel reduces blood flow through the blood vessel and lengthens as it narrows to retain a thrombus within the funnel; a clot-capture element configured to capture the thrombus and to be at least partially withdrawn with the captured thrombus into the funnel; and a microcatheter adapted to carry the clot-capture element to the thrombus. The clot-capture element is movably disposed within the microcatheter in a retracted position. The microcatheter is movably disposed within the aspiration catheter.

Devices and methods for establishing trans-radial access for medical intervention are described. In particular, some embodiments are optimized for consistently safely achieving complete cerebral angiography via a single trans-radial access site. A system may include a catheter with at least two active steering sites. Some embodiments may include at least one balloon. The methods include using said steering mechanisms to help guide and support said catheter. In some embodiments, additional use is made of at least one vascular arch to provide further support and prevent kickback and prolapse of said catheter and any additional devices passed therethrough.

A method for endovascularly replacing a patient's heart valve including the following steps: endovascularly delivering an anchor and a replacement valve supported within the anchor to a vicinity of the heart valve in a collapsed delivery configuration, the anchor having grasping elements adapted to grasp tissue in a vicinity of the heart valve; expanding the anchor, thereby rotating the grasping elements; and grasping the tissue with the rotating grasping elements.

A surgical anchor device for being anchored on the mucous membrane of the inner wall of the intestine, the device having a temporary anchor element presenting anchoring that can be modified in a controlled manner and having a first substantially cylindrical multiply-perforated wall presenting properties of radial elasticity whereby the first wall presents an outer diameter that can be varied in controlled manner, wherein a portion of the inner surface of the first wall is lined with an independent leakproof inner sheath having only its longitudinal ends fastened to the anchor element to define a suction chamber between the inner sheath and the first wall, the temporary anchor element being coupled to a flexible or semi-rigid tube extending outside the anchor element, an open end of the injection-suction tube opening out into the suction chamber enabling air to be injected into or sucked out from the suction chamber.

The present invention provides a filter device, including a filtering part, a constraining part, a stent part, and a connecting part. The filtering part has a first end and a second end opposite to each other. The constraining part is degradable and at least configured to constrain the first end of the filtering part. The stent part has a first end and a second end opposite to each other. The first end of the stent part is connected to the second end of the filtering part, and disposed coaxial with the filtering part. The connecting part is disposed on one or more of the first end of the filtering part and the second end of the stent part, and is configured to connect to an external mechanism, and the constraining part is further configured to constrain the second end of the stent part when the connecting part is disposed at the second end of the stent part. The present invention can be taken out from the human body and can also be partially degraded in the human body so that the occurrence rate of long-term complications is reduced, and secondary surgery can thus be avoided.
