Abstract
A sensing device for a collapsible prosthetic heart valve, the sensing device including an elongated shaft having a proximal end and a distal end, a sensing body coupled to the distal end of the shaft, the sensing body being adapted to fit within a native valve annulus and at least one microelectromechanical sensor attached to the sensing body, the at least one sensing body being capable of measuring a property of tissue.
Claims24
A sensing device for measuring a property of tissue for selecting a collapsible prosthetic heart valve, the sensing device comprising:
- an elongated shaft having a proximal end and a distal end;
- a rigid body having an outer surface, the body being coupled to the distal end of the shaft, the body being adapted to fit within a native valve annulus;
- and
- at least one microelectromechanical sensor attached to the body and being disposed on the outer surface of the body, the at least one sensor having a deflectable portion and being capable of measuring a property of tissue adjacent to the native valve annulus by contacting the tissue against the deflectable portion.
A method for measuring a property of tissue for selecting a collapsible prosthetic heart valve, comprising:
- introducing a device to the native annulus, the device comprising (i) a rigid body having an outer surface and adapted to fit within a native valve annulus and having a first diameter and (ii) at least one microelectromechanical sensor that is attached to the body and disposed on the outer surface thereof, the at least one microelectromechanical sensor being capable of measuring a property of tissue and having a deformable portion;
- and
- obtaining data related to a property of tissue adjacent the native annulus by contacting the deformable portion of the microelectromechanical sensor with the tissue.
A system of measuring a property of tissue for selecting a collapsible prosthetic heart valve, the system comprising:
- a device having (i) a rigid body having an outer surface and adapted to fit within a native valve annulus, and (ii) at least one microelectromechanical sensor attached to the body and disposed on the outer surface of the body, the at least one sensor having a deformable portion and being capable of measuring a property of tissue adjacent to the native valve annulus by contacting the tissue;
- a memory for storing a predefined dataset;
- and
- a processor for using the predefined dataset and information received from the at least one sensor for determining a property of the tissue.
