Embolic protection device for insertion into an aortic arch, with a filter unit, a frame and a feed unit, wherein the filter unit is arranged at the frame and the frame provides a proximal area having a proximal shape, which is arranged in an inner area of the frame and is connected to the feed unit, wherein the proximal shape has a first part and a second part, wherein the second part is formed at one end of the first part.

A method for treating hypertrophic cardiomyopathy (HCM) utilizes an RF ablation electrode needle system that has an RF ablation generator, and an electrode needle. The electrode needle is introduced to puncture within myocardium and to reach the hypertrophic area of the interventricular septum. The RF ablation generator is then turned on to implement single-point or multi-point ablation on the hypertrophic area of the interventricular septum, and then the RF electrode needle is withdrawn from the patient.

A catheter device for transvascular delivery of a medical device to a cardiac valve region of a patient comprises an elongate sheath with a first lumen, a distal end for positioning at a heart valve, a second lumen that extends parallel to or in the sheath, and an expandable embolic protection filter. The filter is arranged to extend from an orifice of the second lumen and, in the expanded, covers ostia of the side branch vessels in the aortic arch.

A percutaneous transluminal angioplasty device includes a catheter defining one or more lumens. A filter is coupled to the catheter adjacent a distal end of the catheter, and the filter is movable between an unexpanded and expanded configuration via a filter activation wire that extends through a lumen. An expandable balloon is coupled to the catheter proximally of the filter, and a stent is disposed over at least a portion of the balloon. To deploy the stent to a target site, the filter is first moved into its expanded position via the filter activation wire. Then, the stent is expanded, and the balloon is inflated to expand the stent further radially. The balloon is then deflated, the filter is contracted, and the catheter, balloon, and filter are removed from the body.

Devices and methods are configured to allow transcarotid or subclavian access via the common carotid artery to the native aortic valve, and implantation of a prosthetic aortic valve into the heart. The devices and methods also provide for embolic protection during such an endovascular aortic valve implantation procedure.

A delivery sheath includes an outer tubular layer and an initially folded inner tubular layer. When an implant passes therethrough, the outer tubular layer expands and the inner tubular layer unfolds into an expanded lumen diameter. The sheath may also include selectively placed longitudinal support rods that mediate friction between the inner and outer tubular layers to facilitate easy expansion, thereby reducing the push force needed to advance the implant through the sheath's lumen.

Devices and methods for providing protection from embolisms and microembolisms in a subject undergoing catheter-based intravascular procedures. The embolic protection devices have an expandable support frame comprising U-shaped members and leg members which facilitate proper placements in a defective valve annulus. The filtering devices expand in the vessels and allow blood flow to continue through the vessels, thereby catching and removing debris of the flowing blood. Also disclosed are embolic protection devices for use with a sutureless valve prosthesis which is implanted via catheter-based methods.

In some examples, a capture assembly configured to remove material of interest, including blood clots, from a body region, including but not limited to the circulatory system, includes a body configured to receive the material of interest. The body can be configured to axially lengthen and shorten.

The invention concerns an embolic protection device for inserting into an aortic arch to prevent embolisms. The invention moreover concerns a handle for such an embolic protection device, as well as a system consisting of said handle and the embolic protection device and a system consisting of a handle, an embolic protection device and a catheter. Through the invention, an embolic protection device for inserting into an aortic arch, comprising a filtering unit and a feeding unit, is provided, wherein the filtering unit comprises a frame and a filter mesh, and the filter mesh is placed on the frame, the filtering unit has a proximal area and a distal area, wherein the filtering unit is designed in such a way that it can, at least partially, be positioned in the aortic arch, and wherein, once the filtering unit is appropriately positioned, haptic feedback is generated, which signals to the user the final position.

Systems and methods can remove material of interest, including blood clots, from a body region, including but not limited to the circulatory system for the treatment of pulmonary embolism (PE), deep vein thrombosis (DVT), cerebrovascular embolism, and other vascular occlusions.
