Abstract
A tether system for securing a prosthetic heart valve within a patient, the tether system comprising a tether defining a longitudinal axis, and a deformable element coupled to the tether, the deformable element having a first deformed shape in a first condition of the deformable element, and having a second substantially straight shape in a second condition of the deformable element so that, when the deformable element is in the second condition, the deformable element extends in a direction along the longitudinal axis.
Claims24
A tether system for securing a prosthetic heart valve within a patient, the tether system comprising:
- a tether defining a longitudinal axis;
- and
- a deformable element coupled to the tether, the deformable element having a first deformed shape in a first condition of the deformable element, and having a second substantially straight shape in a second condition of the deformable element so that, when the deformable element is in the second condition, the deformable element extends in a direction along the longitudinal axis.
A method of tensioning a prosthetic heart valve system, the method comprising:
- positioning a tether at least partially within a heart of a patient, the tether being coupled to at least one of a prosthetic heart valve and an anchor device, a deformable element being coupled to the tether and having a first deformed shape in the absence of applied force;
- tensioning the tether to a threshold tensile force and causing the deformable element, via the tensioning, to change into a second shape different than the first deformed shape;
- and
- imaging the deformable element to confirm if the deformable element has the first deformed shape or the second shape.
