The present invention relates to a silicone coating process that enhances the durability of silicone coatings on the surfaces of surgical needles and other medical devices. surgical needles or silicone-coated medical devices produced by this process have superior lubricity and durability characteristics to facilitate repeated and successive passage through the tissue. The coating compositions used in the novel process contain an excess amount of the polymethyl hydrosiloxane-based crosslinker. After curing, the process uses gamma radiation to treat the lubricant coatings. the coatings have improved durability and performance. The penetration performance of the coated needles by this innovative method remains constant and flat over at least one hundred repeated passes through the tissue or tissue simulating medium. This provides a consistent or flat tactile needle response to the surgeon's hand during a long closure process, rather than an unpredictably increasing force profile. The process is also advantageous for coating reusable instruments, robotic instruments and instruments used in minimally invasive procedures.a presente invenção refere-se a um processo de revestimento com silicone que aprimora a durabilidade dos revestimentos de silicone sobre as superfícies de agulhas cirúrgicas e de outros dispositivos médicos. as agulhas cirúrgicas ou os dispositivos médicos revestidos com silicone produzidos por meio desse processo têm características superiores tanto de lubricidade como de durabilidade, a fim de facilitar passagens repetidas e sucessivas através do tecido. as composições de revestimento usadas no processo inovador contêm uma quantidade em excesso do reticulador à base de polimetil-hidrossiloxano. após a cura, o processo usa radiação gama para tratar os revestimentos lubrificantes. os revestimentos têm durabilidade e desempenho aprimorados. o desempenho de penetração das agulhas revestidas por meio deste método inovador permanece constante e plano ao longo
