摘要： Percutaneous access sheaths used to provide access to the vasculature and heart for the introduction of percutaneous ventricular assist devices (pVADs), and to remain in place for the duration of pVAD use. The sheaths include actively closeable seals engageable to seal against the drive lines of the pVADs to minimize blood loss during pVAD use.

摘要： An intravascular electrode system includes an expandable anchor and a flexible substrate which carries at least one electrode. The anchor is positioned in a blood vessel and expanded to an expanded position to bias the electrode in contact with the vessel wall. The flexible substrate may be longitudinally withdrawn from its position between the anchor and the vessel wall without removing the anchor from the blood vessel. A second flexible substrate may be longitudinally inserted into position between the anchor and vessel wall as replacement for the first substrate.

摘要： To percutaneously deliver a replacement tricuspid valve, a cable is percutaneously positioned with a first end extending out of the venous vasculature at the neck, and a second end extending out of a femoral access point. An eyehook device is positioned over the first end. A tricuspid valve delivery device (TVDD) is advanced over the second end, and then advanced through an IVC into a right atrium. The eyehook device is advanced into the right ventricle, drawing an intermediate portion of the cable into the right ventricle. Contact between the distal end of the eyehook device and the right ventricle is maintained while the TVDD is pushed from the femoral vein. The intermediate portion of cable applies a force to a distal nose of the TVDD that causes the distal nose to be steered into a tricuspid valve annulus as the TVDD is advanced.

摘要： A conduit for creating a passage from a right atrium to a left atrium, through a mitral valve into the left ventricle, and to provide a passage from the left ventricle into the aortic valve. The conduit includes an elongate tubular member having a shaft with a proximal section and a distal loop section at a distal end of the proximal section. The distal loop section includes a passive proximal curve, a steerable distal curve, a generally straight segment extending between the curves, and a distal tip. The shaft in the distal loop section is steerable to cause it to curve back on itself so that proximal curve is formed by a part of the shaft that is closer along the length of the shaft to the distal tip. The shapes of the proximal and distal curves are selected to direct the distal tip into the mitral valve after it has crossed the inter-atrial septum from the right atrium to the left atrium of the heart, and to orient the distal opening of the distal tip towards the aortic valve when the proximal curve is in the mitral valve and the distal tip is in the left ventricle.

摘要： Disclosed are a system and method for performing a medical procedure using direct percutaneous access of an aorta. A main sheath is introduced through an incision formed in proximity to the sternum, and positioned along (and preferable against) a posterior portion of the sternum. Instruments passed through the main sheath are used to form a purse-string suture in an exterior wall of the aorta. An opening is formed in the wall of the aorta in a region encircled by the purse-string suture, and a distal end of an introducer sheath is advanced through the opening into the aorta. A medical procedure, which may be a transcatheter aortic valve replacement, is performed using instruments passed through the introducer sheath into the aorta. After the medical procedure, the introducer sheath is withdrawn from the aorta and, as the introducer sheath is withdrawn, the purse-string suture is tightened to close the opening.

摘要： A steering catheter includes an elongate shaft with an actively steerable distal part. An internal pull wire and an external pullwire extend through the shaft. The shaft has a first position in which the elongate shaft is generally straight and the external pullwire extends along the exterior of the distal portion of the shaft, a second position in which the shaft is curved and in which the external pullwire extends along the exterior of the distal portion of the shaft, and a third position in which the shaft is curved and in which the external pullwire extends laterally between laterally adjacent portions of the distal portion of the shaft, wherein the external pull wire locks the shaft in the curved position.

摘要： A system for use in transseptally delivering a cardiac therapeutic device (“CTD”) to a target site in the heart, includes a CTD having an elongate flexible advancer on its distal end, and a flexible member proportioned for introduction into a vasculature and having a length to extend from the right subclavian vein, through the heart via a transseptal puncture, and to a femoral artery such that a first end of the flexible member is external to the patient at the right subclavian vein or other venous access site and a second end of the flexible member is external to the patient at the femoral artery. The flexible member has a grasper releasably engageable with the advancer.

摘要： A device for facilitating use of instruments disposed through an aortic arch includes an embolic deflector having a first surface positionable in contact with a wall of an aortic arch such that a porous barrier portion of the embolic deflector covers ostia of at least the brachiocephalic and left common carotid arteries. A second surface is disposed on an opposite face from the first surface. A lubricious guide track is disposed on the second surface and extends longitudinally on the embolic deflector. The deflector and/or guide track is supported by a shaft that is extendable through a femoral artery and descending aorta to position the guide within the aortic arch. During use, the device is percutaneously introduced via the femoral artery and advanced into the aorta. The porous barrier portion of the deflector is positioned over the target ostia, and the guide track thus faces into the aortic arch. An instrument passed through the aortic arch, such as an aortic valve delivery system introduced via a femoral artery, is advanced along the lubricious guide track towards a target site (e.g. the aortic valve), minimizing contact between the instrument and the wall of the aorta.
