3D PRINTING OF BIOMEDICAL IMPLANTS - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240009357 titled '3D PRINTING OF BIOMEDICAL IMPLANTS

Simplified Explanation

Methods, compositions, devices, and systems for 3D printing of biomedical implants are disclosed in this patent application. Specifically, the invention relates to the 3D printing of biomedical devices, such as endovascular stents, using photo-curable biomaterial inks, such as methacrylated poly(diol citrate).

• The patent application describes methods and systems for 3D printing of biomedical devices using photo-curable biomaterial inks.
• The biomaterial inks used in the 3D printing process are photo-curable, meaning they can solidify when exposed to light.
• The specific biomaterial ink mentioned in the patent application is methacrylated poly(diol citrate).
• The invention focuses on the 3D printing of biomedical implants, particularly endovascular stents.
• The 3D printing process described in the patent application involves depositing layers of the biomaterial ink and curing them with light to create the desired biomedical device.
• The use of 3D printing technology allows for the fabrication of complex geometries and customized designs for biomedical implants.
• The patent application suggests that the 3D printing of biomedical implants using photo-curable biomaterial inks can provide improved biocompatibility and mechanical properties compared to traditional manufacturing methods.

Potential Applications

• The technology described in the patent application can be used for the 3D printing of endovascular stents, which are used to treat narrow or blocked blood vessels.
• It can also be applied to the 3D printing of other biomedical implants, such as orthopedic implants, dental implants, or tissue scaffolds.

Problems Solved

• Traditional manufacturing methods for biomedical implants may have limitations in terms of design complexity and customization.
• The use of photo-curable biomaterial inks in 3D printing can overcome these limitations by allowing for the fabrication of complex geometries and customized designs.
• The technology described in the patent application can potentially solve the problem of limited biocompatibility and mechanical properties associated with traditional manufacturing methods.

Benefits

• 3D printing of biomedical implants using photo-curable biomaterial inks can provide improved biocompatibility and mechanical properties.
• The ability to fabricate complex geometries and customized designs allows for better patient-specific implant fitting and functionality.
• The technology has the potential to reduce the manufacturing time and cost of biomedical implants compared to traditional methods.
• The use of 3D printing technology enables rapid prototyping and iterative design improvements for biomedical implants.
