Abstract
Determining a shape of a medical device to be implanted into a subject produces an image including a defective portion and a non-defective portion of a surface of a tissue of interest included in the subject. The tissue of interest is segmented within the image. A template, representing a normative shape of an external anatomical surface of the tissue of interest, is superimposed to span the defective portion. An external shape of an implant, is determined as a function of respective shapes of the defective portion as seen in the template, for repairing the defective portion.
Claims16
A three-dimensional medical device comprising:
- an outer surface having a shape corresponding to a deformed three-dimensional template,
- wherein the deformed three-dimensional template is formed by deforming a three-dimensional template representing a normative shape of an anatomical surface of a target tissue, wherein the target tissue comprises a portion with a defect and a portion without a defect,
- wherein the three-dimensional template representing a normative shape of an anatomical surface of a target tissue is deformed to a computer-generated three-dimensional representation rendered from the image data of the target tissue.
A three-dimensional model for use in fabricating an implantable medical device, the model comprising:
- an outer surface having a shape corresponding to a deformed three-dimensional template,
- wherein the deformed three-dimensional template is formed by deforming a three-dimensional template representing a normative shape of an anatomical surface of a target tissue, wherein the target tissue comprises a portion with a defect and a portion without a defect,
- wherein the three-dimensional template representing a normative shape of an anatomical surface of a target tissue is deformed to a computer-generated three-dimensional representation rendered from the image data of the target tissue.
A three-dimensional medical device comprising:
- an outer surface configured to drop-in to a missing segment of bony structure,
- wherein the body fits precisely within contours of the missing segment,
- wherein the body is fabricated based on a determined three-dimensional shape of the medical device, which is determined by deforming a computer-generated three-dimensional template to a computer-generated three-dimensional representation,
- wherein the computer-generated three-dimensional representation is rendered from image data of target tissue, which includes tissue surrounding the missing segment of bony structure that defines the contours of the missing segment, and
- wherein the three-dimensional template represents a normative shape of an anatomical surface of the target tissue.
