Method of manufacturing a medical device for external application to the head of a patient

1. A method of manufacturing a custom protective device configured to be removably and externally affixed to a peripheral scalp portion of a patient's head, the peripheral scalp portion overlying a depressed portion of said patient's head where a portion of the cranium of said patient has been removed, and the peripheral scalp portion defined by a portion of said scalp extending outward about the entire periphery of said depressed portion by a predetermined distance on said scalp surrounding said depressed portion, the method comprising:

generating a three dimensional digital image of the external surface of said scalp of said patient's head, said three dimensional digital image representing at least said peripheral scalp portion and said depressed portion;

processing said three dimensional digital image to identify said peripheral scalp portion and said depressed portion represented by said three dimensional digital image;

generating a three dimensional digital image file of said identified scalp and depressed portions;

processing said three dimensional digital image file to determine one or more of a size, a shape, a contour, and a positional alignment for said custom device with respect to said patient's head;

generating a device data file from said processed three dimensional digital image file; and

utilizing said device data file to fabricate said custom device for said patient, the custom device further configured to cover said peripheral scalp portion and said depressed portion upon said affixing until the removed cranium portion is replaced.

2. A method in accordance with claim 1 ,

wherein said processing of said three dimensional digital image file is conducted such that said custom device is further configured to engage said peripheral scalp portion in a fluid tight and airtight engagement.

3. A method in accordance with claim 1 ,

wherein at least a portion of said custom device is formed from a transparent material.

4. A method in accordance with claim 1 , further comprising:

providing said custom device with at least one port.

5. A method in accordance with claim 4 , further comprising:

providing said at least one port with one of a valve, a sensor, and a transducer.

6. A method in accordance with claim 1 ,

wherein said fabricating is conducted by a three dimensional printer using said device data file.

7. A method in accordance with claim 1 ,

wherein at least a portion of said custom device comprises a convex shape.

8. A method in accordance with claim 1 , wherein said removed cranium portion is a bone flap.

9. A method in accordance with claim 1 , wherein said custom device is a cranial plate.

10. A method in accordance with claim 1 , wherein said custom device comprises optically transparent polycarbonate permitting observation of the depressed portion therethrough after said affixing.

11. A method in accordance with claim 1 , wherein said fabricating is conducted by one of an additive machining process, a subtractive machining process, and a combination of additive and subtractive machining.

12. A method in accordance with claim 1 , wherein said fabricating is conducted by thermoplastic forming.

13. A method in accordance with claim 1 , wherein said generating of a three dimensional digital image is conducted by steps of:

capturing a plurality of images of the external surface of said scalp of said patient's head; and

processing the plurality of images to generate the three dimensional digital image.

14. A method in accordance with claim 13 , wherein said capturing is conducted using a stereographic digital camera apparatus.

15. A method in accordance with claim 13 , wherein said plurality of images are captured simultaneously.

16. A method in accordance with claim 1 , wherein upon said affixing, said custom device is further configured to protect intracranial contents of said patient from atmospheric pressure.
