Latest Patents

Boutani's latest patents include a groundbreaking biodegradable and resorbable surgical material. This material is composed of molded articles made from poly(lactic acid) or copolymers of lactic acid and glycolic acid. The articles are molecularly oriented, exhibiting impressive mechanical properties such as a bending strength ranging from 1.6 × 10^3 to 2.5 × 10^3 kg/cm² and a bending modulus between 5.5 × 10^2 and 24.0 × 10^2 kg/cm². Additionally, the crystallinity of the material, determined by density measurement, falls between 10% and 60%. Notably, at least 80% of the initial strength of these articles is maintained after immersion in saline at 37°C for three months.

Another significant patent involves a one-component polyurethane gel and couplers designed for ultrasonic diagnostic probes. This gel is synthesized by reacting a polyol with a room temperature liquid alkylene oxide chain and a polyurethane polyisocyanate prepolymer. The resulting gel is notable for its safety, as it does not cause bleeding or evaporation of the dispersion medium, making it highly suitable for medical applications.
