Fenestration template for endovascular repair of aortic aneurysms
ActiveUS20130296998A1Improving fenestration processStentsAdditive manufacturing apparatusMedical imaging dataComputed tomography
To provide simple yet accurate stent graft fenestration, a patient-specific fenestration template is used as a guide for graft fenestration. To generate the fenestration template, a patient's medical imaging data such as CT scan data may be used to generate a 3-D digital model of an aorta lumen of the patient. The aorta lumen may encompass one or more branch vessels, which may be indicated on the 3-D digital model. Based on the 3-D digital model or a segment thereof, the fenestration template may be generated, for example, using 3-D printing technology. The fenestration template may include one or more holes or openings that correspond to the one or more branch vessels. To fenestrate a stent graft, the fenestration template is coupled to the stent graft so that the holes or openings on the fenestration template indicate the fenestration locations.

Method for rapid generation of multiple investment cast parts such as turbine or compressor wheels
ActiveUS20100006252A1Remove capital expenditureReduce processing timeAdditive manufacturing apparatusFoundry mouldsInvestment castingRefractory
The process for investment casting of complex shapes has historically had 6 basic steps in it. Depending upon the path taken, these discrete steps have been reduced to either 5 steps, or to 2 steps, discarding the unwanted steps. Instead of having to generate the shape of each sacrificial pattern, the process generates either(A) a male tree containing a plurality of sacrificial patterns, already on their runners, onto which a mold shell can be formed, or,(B) a female shell, made of a refractory material, and forming internally the outside surfaces of the plurality of patterns and runners.This process removes both capital expenditure for tooling and process time by up to 90%. By removing several lengthy, time-dependant steps from the process the part cost and lead time are reduced.
