Abstract
Medical devices and methods that provide for improved accuracy when positioning of a synthetic structure, such as a MEMS device or a stent, within a biological feature of a patient, such as a blood vessel, are disclosed. A blood vessel sizing device is configured for placement on the skin of a patient near a feature of interest (e.g. a blood vessel to be imaged). The device may include one or more radiopaque elements, including a target element, and one or more positioning markers having known sizes. A clinician may use the radiopaque elements to identify a portion of a blood vessel suitable for positioning of the synthetic structure.
Claims20
A non-transitory computer-readable medium comprising computer-executable instructions, that when executed, cause a processor to:
- receive radiological image data of an area of a body of a patient as a radiopaque contrast agent is present in one or more biological features within the area;
- identify, from the received radiological image data, a radiopaque target element of a sizing device positioned on an area of skin of the patient;
- compare the radiopaque target element to the one or more biological features to identify a biological feature, from the one or more biological features, with a dimensional property within an acceptable dimensional range indicated by the radiopaque target element;
- determine a target location of the biological feature relative to one or more radiopaque positioning markers of the sizing device;
- identify, from the radiological image data, a radiopaque portion of a synthetic structure to be positioned at the biological feature;
- and
- determine a location of the radiopaque portion of the synthetic structure relative to the target location.
(canceled)
A method comprising:
- receiving radiological image data of an area of a body of a patient as a radiopaque contrast agent is present in one or more biological features within the area;
- identifying, from the received radiological image data, a radiopaque target element of a sizing device positioned on an area of skin of the patient;
- comparing the radiopaque target element to the one or more biological features to identify a biological feature, from the one or more biological features, with a dimensional property within an acceptable dimensional range indicated by the radiopaque target element;
- determining a target location of the biological feature relative to one or more radiopaque positioning markers of the sizing device;
- identifying, from the radiological image data, a radiopaque portion of a synthetic structure to be positioned at the biological feature;
- and
- determining a location of the radiopaque portion of the synthetic structure relative to the target location.
(canceled)
A sizing device, comprising:
- a planar base structure having a front surface and a back surface, wherein the base structure is:
- configured to be placed on a user's skin during radiological imaging of a target area of the user;
- and
- radiolucent to light with a wavelength in the visible spectrum;
- a series of radiopaque positioning markers positioned on the base structure and spaced apart along a longitudinal axis of the sizing device;
- and
- a radiopaque target element positioned on the front surface of the base structure, wherein the radiopaque target element indicates an acceptable dimensional range of a biological feature for positioning of a synthetic structure therein.
