Patent number: 6647803Abstract: A machine, and operating procedures for a machine, for automatically threading, swaging and packaging surgical needles. A first mechanism is used to suture the needles and to pull test the needles to determine if certain maximum and minimum pull test requirements are met. The sutured needles are then transferred to packages on a second mechanism, and that mechanism indexes the packages through a series of stations to complete the packaging of the needles. Various checks are made at the packaging mechanism before that mechanism is operated to index the needle packages; and different items at the station used to pull test the needles, are monitored to determine if they return timely to predetermined positions. Also, check are made at the station at which the needles are transferred to the packages, to be sure that those items are in preferred positions before the packages are moved.Type: GrantFiled: February 16, 2000Date of Patent: November 18, 2003Assignee: Ethicon, Inc.Inventors: David Demarest, Michael G. Hodulik, Timothy P. Lenihan, John F. Blanch

Patent number: 6138053Abstract: Methods and systems for packaging surgical needles. In this system, a plurality of packages are indexed, by means of a package carrier, through a plurality of work stations, at which various operations are performed on the packages. In particular, at each work station, an operating device is moved from a home position to an operating position to perform an operation on the package: and after finishing the operation, the operating device is returned to the home positions. With all of the operating devices in their respective home positions, the package carrier can then be moved to index the packages forward. Each of the work stations generates a respective return home signal when the operating device of the work station returns to its home position.Type: GrantFiled: June 17, 1997Date of Patent: October 24, 2000Assignee: Ethicon, Inc.Inventors: David Demarest, Michael G.

Patent number: 5983601Abstract: A machine and a method for the automated packaging of armed sutures or; in effect, surgical needles having sutures attached thereto and, more particularly, an automated machine for the high-speed individualized packaging of single or individual surgical needles each having an attached suture into a tray and detachable cover providing a suture package utilized for the packaging of the individual or single needles and attached sutures. Additionally, the automated packaging machine incorporates operative mechanism adapted to wind the sutures into a peripheral channel of the tray and facilitating the attachment of the cover to the tray which contains the single needle and attached wound suture, and which cover concurrently constitutes a product-identifying label as a component of the tray, and upon removal of the cover enables a user to gain access to the contents of the tray; in essence, the armed suture.Type: GrantFiled: February 6, 1998Date of Patent: November 16, 1999Assignee: Ethicon, Inc.Inventors: John F. Blanch, David D. Demarest, Robert A. Daniele, Anthony Esteves, William F. Smith, Michael G. Hodulik, Teresa M. Shaw, George Horst Reinemuth, Richard Paul Branco, Matthew Cafone

Patent number: 5920482Abstract: Methods and procedures for varying parameters at a work station where different size and/or type needles are automatically sutured to different size and/or type sutures, such as: a method and system for applying a predetermined, given tension to different size and/or type sutures; a system and method for inserting a suture into different size and/or type needles to a predetermined, given depth; and a method and system to cool different size and/or type sutures for a predetermined, given length of time. Values for these parameters may be stored in a supervisor computer and then transmitted to controllers to operate the work station with these parameter values for each of a plurality of different size and/or type sutures and/or needles.Type: GrantFiled: February 21, 1997Date of Patent: July 6, 1999Assignee: Ethicon, Inc.Inventors: David D. Demarest, Michael G. Hodulik, Timothy P. Lenihan, Loy William Shreve, II

Patent number: 5793634Abstract: Procedures for adjusting or reseting the pressure used to swage needles to suture at a needle swaging station. The forces required to break the sutures from the needles are measured and added to a data base; and each time a value, or sample, is added to that data base, an average of all the sample values in the data base is calculated. Each time an average value is calculated, that value is compared to a first range, referred to as a reject range. If any calculated average value falls outside that reject range, then the swaging pressure is adjusted and the procedure is restarted, with a new, or empty, data base. Also, once the sample reaches a given size, such as eight or nine samples, the calculated average values are also compared to a second range, referred to as an accept range, and which is within and narrower than the reject range. If a calculate average value is within this accept range, the swaging pressure is considered acceptable and the procedure terminates immediately.Type: GrantFiled: February 21, 1997Date of Patent: August 11, 1998Assignee: Ethicon, Inc.Inventors: David D. Demarest, Michael G. Hodulik, Teresa M. Shaw, Irwin J. Shiffer, Anthony Esteves
