Patent number: 8081307Abstract: A system and method for inspecting stents can involve an inspection camera to take an image of the stent and a computer system for analyzing the image to determine the presence of any coating defects. The determination can be made by masking out a portion of the stent, identifying deviations from a strut edge, and/or highlighting features protruding from a stent external boundary defining an outer diameter. The image can be taken after a focus feedback camera determines the position of the stent.Type: GrantFiled: September 22, 2010Date of Patent: December 20, 2011Assignees: Abbott Cardiovascular Systems Inc., ATS Automation Tooling Systems Inc.Inventors: Ian Cameron, Andrew David Coppin Maw, Hong Zhang, Calden Wloka, Sidney Watterodt, Sang joon Park, Anthony S. Andreacchi, Yung-Ming Chen, Arnoldo M. Currlin, Antonio Garcia, Jason Van Sciver, Bryan D. Glenn

Publication number: 20110281019Abstract: A system and method for coating an expandable member of a medical device comprises providing a dispenser in fluid communication with a fluid source with the dispenser having at least one outlet to dispense fluid of the fluid source therefrom. The outlet(s) of the dispenser is positioned proximate a surface of an expandable member, with relative movement between the outlet(s) and the surface of the expandable member established along a coating path, and fluid is dispensed from the dispenser to form a substantially continuous bead of fluid between the at least one outlet and the surface of the expandable member along the coating path, and simultaneously drying the fluid while dispensing the fluid from the dispenser to control flow of fluid on the surface of the expandable member. The fluid source can include a variety of therapeutic agents.Type: ApplicationFiled: May 16, 2011Publication date: November 17, 2011Applicant: Abbott Cardiovascular Systems Inc.Inventors: Victoria M.

Publication number: 20110281020Abstract: A system and method for coating an expandable member of a medical device comprising a support structure to support the expandable member and a dispenser positioned with at least one outlet proximate a surface of an expandable member. A drive assembly establishes relative movement between the at least one outlet and the surface of the expandable member to apply fluid on the surface of the expandable member along a coating path. A guide maintains a substantially fixed distance between the at least one outlet and the surface of the expandable member during relative movement therebetween by displacing the expandable member relative to the at least one outlet.Type: ApplicationFiled: May 17, 2011Publication date: November 17, 2011Applicant: Abbott Cardiovascular Systems Inc.Inventors: Victoria M.

Patent number: 8055360Abstract: A system and method of aligning a stent with a stent support involves taking two images of the stent that has been placed on the stent support and determining from the two images whether the stent is aligned with the stent support. The stent can be rotated so that the two images are of different views of the stent. A computer can be configured to receive the images and to determine the whether the stent is aligned. A backlight can be used to take images of the stent in silhouette. A portion of the stent support can be re-positioned based on an image taken of the stent.Type: GrantFiled: October 23, 2010Date of Patent: November 8, 2011Assignees: Abbott Cardiovascular Systems Inc., ATS Automation Tooling Systems Inc.Inventors: Sang joon Park, Shaulaine Choo, Anthony S.

Patent number: 7853340Abstract: A method for aligning a stent with a stent support includes the steps of (1) placing a stent support and a stent mounted on the stent support in a vertically position with the stent support's first support element at a lower position and the stent support's second support element at an upper position; (2) obtaining a digital image of the stent support and stent; (3) analyzing the digital image of the stent support and stent to compute the vertical position of the stent's upper end; (4) computing a desired position of the second support element based on the position of the stent's upper end; and (5) using a positioning device to move the second support element to the desired position. The movement of the second support element causes the conical sections of the first and second support elements to engage the respective ends of the stent to center the stent around a core element of the stent support and to secure the stent in a longitudinal direction of the stent support.Type: GrantFiled: September 11, 2009Date of Patent: December 14, 2010Assignees: Abbott Cardiovascular Systems Inc., ATS Automation Tooling Systems Inc.Inventors: Sang joon Park, Shaulaine Choo, Anthony S.

Publication number: 20090317537Abstract: A system and method for coating an endoprosthesis involves an applicator capable of delivering a coating substance to the endoprosthesis without spraying. The applicator may have a tube or die through which a coating substance is moved upwards by capillary action or by means of a pump so as to form an accumulation of the coating substance at an upper portion of the applicator. The endoprosthesis can be lowered onto the accumulation, then axially translated or rotated in order to transfer the coating substance to selected portions of the endoprosthesis. The applicator is lowered and/or the endoprosthesis is raised in order to form gaps in the coating. Selective coating of abluminal or luminal surface of the endoprosthesis may also be performed by allowing the surface to skip on a liquid surface of a pool of the coating substance.Type: ApplicationFiled: June 24, 2008Publication date: December 24, 2009Inventor: Anthony S.

Publication number: 20090255827Abstract: An electropolishing system including an anode, a cathode, a rolling block and a motion controller. The anode is configured to removably retain a metal device to be electropolished, and may be formed as a bar made from a solid cylindrical piece of metal or other configurations, such as wires with hooks. The anode transfers the electricity to the metal device while grooming the surface of the metal device as it contacts the rolling block. The cathode may be configured as a mesh and completes the electrical circuit. The rolling block is formed from a relatively smooth, solid material and positioned so as to allow the metal device to roll against the surface of the block. The motion controller is configured to provide vertical and horizontal movement of the anode and metal device, using force transducers to control the compression of the metal device against the rolling block.Type: ApplicationFiled: April 10, 2008Publication date: October 15, 2009Applicant: ABBOTT CARDIOVASCULAR SYSTEMS INC.Inventors: Anthony S.
