Summary of the Inventive Concept

An improved microneedle fabrication and implantation system for precise and efficient implantation of devices into biological tissues, addressing limitations of existing microneedle designs.

Background and Problem Solved

The original patent for microneedle fabrication and device implantation has limitations in terms of precision, safety, and efficiency. The new inventive concept addresses these limitations by introducing temperature control mechanisms, ablating outer membranes, and applying nano-coatings to enhance biocompatibility.

Detailed Description of the Inventive Concept

The new system comprises a microneedle fabricated using the methods of claim 1, with additional features such as temperature control mechanisms to regulate the temperature of the biological tissue during implantation. The system also includes a method for inserting an implantable device into a biological tissue, involving ablating a section of the outer membrane using a laser and inserting the implantable device through the ablated section using a microneedle. Furthermore, the microneedle is designed with a primary helix and a secondary helix, where the primary helix is brazed with a braze material and the secondary helix is coated with a bio-compatible material. The fabrication method involves applying a nano-coating to the primary helix to enhance its biocompatibility.

Novelty and Inventive Step

The new claims introduce novel features such as temperature control mechanisms, ablating outer membranes, and applying nano-coatings, which are not present in the original patent. These features provide a significant improvement in precision, safety, and efficiency of the microneedle fabrication and implantation system.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include using different materials for the microneedle, varying the design of the primary and secondary helices, or incorporating additional features such as sensors or actuators to enhance the implantation process.

Potential Commercial Applications and Market

The enhanced microneedle fabrication and implantation system has potential commercial applications in the fields of neurosurgery, ophthalmology, and dermatology, with a target market including medical device manufacturers, research institutions, and hospitals.
