摘要:
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.

The invention provides a two-part package and method of use for a pre-attached medical implant and delivery tool system. The package includes a wet compartment and a dry compartment and allows a pre-attached implant and delivery tool system to be at least partially stored immersed in a fluid in the wet compartment and at least partially stored in the dry compartment. In one embodiment the implant comprises a replacement heart valve, and the heart valve is stored inside the wet compartment while the heart valve delivery tool remains dry in the dry compartment.

摘要:
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.
摘要:
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.
摘要:
A support member for a catheter sheath is disclosed. The support member has a series of ribs with a distal member having integrated fingers for providing radial compliance. The support member provides sufficient axial stiffness to provide a desired pushability of a minimally invasive device for replacing a heart valve. Various alternative embodiments are also described.
