  • Patent number: 11957572
    Abstract: Implementations described and claimed herein provide systems and methods for manufacturing customized cardiovascular devices. In one implementation, patient cardiovascular data for a patient is received at a controller. The patient cardiovascular data is captured using a patient interface. A printing profile for a cardiovascular medical device is received at the controller. A patient specific three-dimensional model of the cardiovascular medical device customized for the patient using the patient cardiovascular data and the printing profile is generated. The patient specific three-dimensional model of the cardiovascular medical device is sliced into a plurality of outlines using the controller. Print instructions based on the plurality of outlines are generated using the controller. A polymeric material is manipulated according to the print instructions into a customized polymeric cardiovascular medical device for the patient.

  • Publication number: 20220168474
    Abstract: A method for treating a bone defect extending between a proximal bone structure and a distal bone structure of a patient may include resecting a region of bone between the proximal bone structure and the distal bone structure and encompassing the bone defect, positioning a biodegradable osteogenic scaffold within a biodegradable sleeve, coupling the biodegradable sleeve to a fixation member, positioning the biodegradable sleeve between the proximal bone structure and the distal bone structure, and attaching the fixation member to each of the proximal bone structure and the distal bone structure.
