Abstract:
The present invention relates to apparatus and methods for endovascularly delivering and releasing a prosthesis, e.g., an aortic prosthesis, within and/or across a patient's native heart valve, referred to hereinafter as replacing the patient's heart valve. In some embodiments the delivery system comprises a plurality of first actuatable element adapted to engage a plurality of second elements in a first configuration to capture the implant within the delivery system, and wherein the plurality of first actuatable element are adapted to engage the plurality of second elements in a second configuration and to release the implant from the delivery system.
Abstract:
The disclosure pertains to profile reduction seals associated with heart valve replacements which may reduce or eliminate paravalvular regurgitation and methods of fabricating such seals. The generally cylindrical multilayer seals of the disclosure include a crown-like end and reinforcing elements which facilitate compression of the seal and associated device by minimizing bunching of the seal as it enters a delivery system.
Abstract:
Apparatus for endovascularly replacing a patient's heart valve, including: a delivery catheter having a diameter of 21 french or less; an expandable anchor disposed within the delivery catheter; and a replacement valve disposed within the delivery catheter. The invention also includes a method for endovascularly replacing a heart valve of a patient. In some embodiments the method includes the steps of: inserting a catheter having a diameter no more than 21 french into the patient; endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve through the catheter; and deploying the anchor and the replacement valve.
Abstract:
The invention includes methods of and apparatus for endovascularly replacing a heart valve of a patient. One aspect of the invention provides a method including the steps of endovascularly delivering a replacement valve and an expandable anchor to a vicinity of the heart valve in an unexpanded configuration; and applying an external non-hydraulically expanding or non-pneumatically expanding actuation force on the anchor to change the shape of the anchor, such as by applying proximally and/or distally directed force on the anchor using a releasable deployment tool to expand and contract the anchor or parts of the anchor. Another aspect of the invention provides an apparatus including a replacement valve; an anchor; and a deployment tool comprising a plurality of anchor actuation elements adapted to apply a non-hydraulically expanding or non-pneumatically expanding actuation force on the anchor to reshape the anchor.
Abstract:
An elongated member and a method of manufacturing an elongated member may include first, second, and third elongated rod mandrels. The first, second, and third elongated rod mandrels may be fixed together at predetermined proximal and distal locations and at a ball tip. The first, second, and third rod mandrels may be disposed within a tubular coupling element and fixed to the tubular coupling element at the ball tip. The tubular coupling element may be placed into abutment with and fixed to the distal end of an elongated shaft.
