With a total of 5 patents to his name, Roche's work has had a lasting impact on the development of specialized products.
Latest Patents
One of Roche's latest patents is the "Low Profile Ostomy Filter." This innovative filter is designed for ostomy appliances and features a heat-sealable microporous film layer, a filter layer made of melt-blown microfibers loaded with adsorbent particles, and a cover layer. The microporous film layer allows for the rapid release of flatus or other gases, achieving a Gurley value of less than about 100 seconds per 50 cc. The estimated service life of the melt-blown microfiber filter web is about three days or more, with a web basis weight of approximately 700 grams/m² or less. This low-profile filter can be securely sealed to the outside face of an ostomy appliance, ensuring no liquid or gas bypass occurs.
Another significant patent by Roche is the "Mass Terminable Cable." This invention involves a ribbon cable or discrete wires that are surrounded by a layer of thermally stable, crush-resistant, fibril microporous heat-sealable thermoplastic crystallizable polymer dielectric. The thermoplastic dielectric has a void volume exceeding 70%, and the propagation velocity of the insulated conductor is greater than 85% of the propagation velocity in air. Additionally, the crush resistance of the material is impressive, with a recovery rate greater than 92% of the initial thickness after being subjected to a 500-gram weight for 10 minutes.
