Patent number: 8967077Abstract: A system and method for photo-grafting a coating polymer onto the surface of a medical device are provided. The system comprises a plurality of stations including a novel grafting station. The system and method of the invention are both time- and resource-efficient. The system includes several stations, each station including a dipping tank. The system allows for the automated, semi-automated, or manual dipping of medical devices into the dipping tanks in a specified order, as desired, wherein at least one of the stations is a grafting station for photo-grafting the coating polymer onto the surface of the medical device. The system is modular, which allows for modification of the process as required, depending on the needs of the user. The system may comprise stations for incorporating an antimicrobial agent into the coating, and/or for rendering the coating lubricious.Type: GrantFiled: September 28, 2010Date of Patent: March 3, 2015Assignee: Covalon Technologies, Inc.Inventors: Hamed Abbasian, Pamela Chan, Valerio DiTizio, Vyacheslav Dudnyk, Zhaopeng Li, Said Loloie, Natali Yakeemovich, Frank DiCosmo

Patent number: 8920886Abstract: One aspect of the present disclosure can include a method for grafting a coating polymer onto a surface of a device. The method can include the following steps: a) submerging the device into a photoinitiator solution; b) without first drying the device, submerging the device into a polymerizable solution; c) bubbling an oxygen-scavenging gas through the polymerizable solution; d) applying a UV light to the device to activate the photoinitiator, thereby grafting the coating polymer onto the device; and e) drying the device.Type: GrantFiled: September 28, 2010Date of Patent: December 30, 2014Assignee: Covalon Technologies, Inc.Inventors: Hamed Abbasian, Pamela Chan, Valerio Ditizio, Vyacheslav Dudnyk, Zhaopeng Li, Said Loloie, Natali Yakeemovich, Frank DiCosmo

Patent number: 8697112Abstract: A method for treating a surface with a therapeutic agent is disclosed. The method comprises precipitating a therapeutic agent from a hydrophilic polymeric base layer with which the therapeutic agent has been complexed, to form a layer comprising microparticles of the therapeutic agent on the hydrophilic polymeric base layer, the hydrophilic polymeric base layer being grafted to the surface. Devices comprising a surface having a hydrophilic polymeric base layer comprising a hydrophilic polymer grafted to the surface and a layer comprising microparticles of a therapeutic agent disposed on and complexed with the hydrophilic polymeric base layer are also disclosed.Type: GrantFiled: July 6, 2012Date of Patent: April 15, 2014Assignee: Covalon TechnologiesInventors: Vyacheslav Dudnyk, Valerio DiTizio
