Devices and methods for anatomic mapping for prosthetic implants
A method of generating a patient-specific prosthetic includes receiving anatomic imaging data representative of a portion of a patient's anatomy. A first digital representation of the anatomic imaging data is defined. The first digital representation of the anatomic imaging data is modified. A second digital representation of the portion of the patient's anatomy is defined based on the modifying of the first digital representation of the anatomic imaging data. A patient-specific prosthetic template of the portion of the patient's anatomy is generated based at least in part on the second digital representation of the anatomic imaging data.
1. A device for locating a fenestration position on a stent graft, the device comprising:
a) a patient-specific fenestration template configured to be coupled to the stent graft, the patient-specific fenestration template representing a portion of a patient's aorta, the portion of the patient's aorta having a first branch blood vessel extending from the aorta and a second branch blood vessel extending from the aorta,
b) the patient-specific fenestration template having a first marker corresponding to a predicted location of the first branch blood vessel, and a second marker corresponding to a predicted location of the second branch blood vessel;
wherein the predicted location of the first marker is based on a modified digital representation of the portion of the aorta including:
data representative of a first location of the first branch blood vessel, and data representative of a second location of the first branch blood vessel,
the second location of the first branch blood vessel is different than the first location of the first blood vessel.
2. The device of claim 1 , wherein the portion of the patient's aorta has a first configuration, and the modified digital representation of the portion of the patient's aorta is associated with a second configuration of the portion of the patient's aorta, the portion of the patient's aorta being transitioned from the first configuration to the second configuration in response to insertion of the stent graft.
3. The device of claim 2 , wherein the modified digital representation of the portion of the patient's aorta is based on a centerline of the portion of the patient's aorta in the second configuration.
4. The device of claim 3 , wherein the predicted location of the first marker and the predicted location of the second marker is determined based on the centerline of the portion of the patient's aorta in the second configuration.
5. The device of claim 1 , wherein the patient-specific fenestration template is hollow.
6. The device of claim 5 , wherein the patient-specific fenestration template is configured to receive a stent graft within a lumen thereof.
7. The device of claim 1 , wherein the patient-specific fenestration template is substantially annular.
8. The device of claim 1 , wherein the first branch blood vessel corresponds to a renal artery.
9. The device of claim 1 , wherein the diameter of a first fenestration corresponds to a diameter of the first branch blood vessel.
10. The device of claim 1 , wherein the predicted location of the second marker is based on a modified digital representation of the portion of the aorta including: data representative of a first location of the second branch blood vessel, and data representative of a second location of the second branch blood vessel, the second location of the second branch blood vessel is different than the first location of the second blood vessel.
