ADDITIVE MANUFACTURING FOR MEDICAL DEVICES - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240009925 titled 'ADDITIVE MANUFACTURING FOR MEDICAL DEVICES

Simplified Explanation

The abstract describes an additive manufacturing system for producing a medical catheter or lead, along with the method involved. The system includes a heating cartridge with an interior volume and at least one filament port. It also has a heating element that is thermally coupled to the heating cartridge to heat the interior volume. A filament handling system is included to feed at least one filament through the filament port, and a substrate handling system is present. The substrate handling system includes a clamp to secure a portion of a substrate, which can be moved relative to the heating cartridge to apply a jacket to the substrate. In some embodiments, a subassembly with an electrode ring is positioned on the substrate, and the jacket is printed to cover at least a portion of the subassembly while being spaced apart from the electrode ring.

• The system includes a heating cartridge with an interior volume and at least one filament port.
• A heating element is thermally coupled to the heating cartridge to heat the interior volume.
• A filament handling system is present to feed at least one filament through the filament port.
• A substrate handling system includes a clamp to secure a portion of a substrate.
• The substrate can be moved relative to the heating cartridge to apply a jacket to the substrate.
• A subassembly with an electrode ring can be positioned on the substrate.
• The jacket is printed to cover at least a portion of the subassembly while being spaced apart from the electrode ring.

Potential applications of this technology:

• Manufacturing medical catheters or leads with improved functionality and customization.
• Producing medical devices with precise and controlled jacketing of subassemblies.
• Creating complex geometries and structures for medical devices.

Problems solved by this technology:

• Traditional manufacturing methods may not allow for precise and controlled jacketing of subassemblies.
• Limited customization options for medical catheters or leads.
• Difficulty in creating complex geometries and structures for medical devices.

Benefits of this technology:

• Improved functionality and customization of medical catheters or leads.
• Enhanced control and precision in jacketing subassemblies.
• Ability to create complex geometries and structures for medical devices.
