Abstract: Devices and methods for closing access points in tissue are described. The devices include a tubular element fabricated form, for example, biologic material, a biologic tubular structure, or synthetic material. Using minimally invasive procedures, the devices and methods described herein allow implantation of the tubular element through the access point or wound such that it traverses the tissue. The tube has a sealed end which prevents leakage of fluid from, for example, the heart or a vessel upon securing the tube to the tissue.

Abstract: 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.

Abstract: A crimper device can facilitate sheathing of a stent frame for vascular delivery. The device can include first and second components that rotate relative to each other to drive radial movement of one or more compression members of the device. The one or more compression members can direct and balance a compressive force within an aperture of the device. In use, the stent frame can be positioned within the aperture and be compacted by actuation of the compression members.

Abstract: A valve prosthesis and implantation device, and methods for use are provided. The devices may be used for transcatheter delivery of an aortic valve prosthesis or transapical delivery of a mitral valve prosthesis. The implantation device utilizes movable claspers for both positioning and anchoring the valve prosthesis, reducing the extent of imaging needed during the implantation procedure.
