AI Technical Summary

Benefits of technology

This patented technology helps improve the mechanical property of certain materials used for medical purposes like cervixes or tissue ablation tools by adding specific elements that enhance their performance. These improvements include increased tensile strength without increasing weight, reduced costs due to fewer steps needed during production compared with traditional methods such as casting molten metal into ingots made from other metals, and enhanced hardness when heat treated at different stages after fabrication.

Problems solved by technology

This patented technical problem addressed in that patents relates to an apparatus called uteri-dilators which can be inserted into the vagina during medical procedures such as endovascular intervention (EVI) treatment without causing damage due to their specific shapes and precise dimensions required.
