Patent number: 8388349Abstract: An anastomosis training device and related methods of use that provides medical professionals with real-time feedback of pulling force. The anastomosis training device can include a housing portion, a spring member, a proximal catheter portion and a distal catheter portion. The housing portion can include an external tubing member that slidingly retains an internal tubing element and the spring member. A proximal wire assembly attaches the spring member to a manipulation assembly and a distal wire assembly attaches the spring member to a retention member that allows the anastomosis training tool to be anchored to a suitable surface. As a user applies a pulling force to the manipulation assembly, the internal tubing member is slidably withdrawn from the external tubing member to expose a visible force scale that indicates the level of pulling force being applied by the user.Type: GrantFiled: January 14, 2010Date of Patent: March 5, 2013Assignee: AMS Research CorporationInventors: Jonathan J. Lund, Larry E. Waldack

Patent number: 8276591Abstract: A method of preventing inadvertent inflation of an implantable prosthetic includes biasing a valve assembly such that an outlet is substantially closed and using inadvertent pressure increases from the inlet to supplement the biasing of the valve assembly. It may further include the step of preventing fluid flow through the outlet by selectively varying fluid pressure within a bypass passageway having a first end which is in fluid communication with an inlet and a second end which is in fluid communication with a chamber. And, may also additionally include the step of displacing a flexible abutting wall disposed between the chamber and the valve assembly so that the abutting wall is caused to contact the valve assembly and urge the valve assembly into a closed position when the fluid pressure within the chamber exceeds a predetermined amount.Type: GrantFiled: October 14, 2008Date of Patent: October 2, 2012Assignee: AMS Research CorporationInventors: Gregory J. Henkel, Larry E. Waldack, Charles C. Kuyava, Randy L. Morningstar, John G. Almli

Patent number: 7438682Abstract: A pump assembly for a penile implant is provided having a mechanism which prevents spontaneous inflation of the cylinders implanted within the patient. The pump assembly has an actuating bar with ribs to enhance the spring force applied to a flow valve, a support structure to support and appropriately position the actuating bar, and a check valve made of metal with a segment covered with a plastic material. The preventative mechanism uses overpressure generated by the reservoir during unintentional compression to effectively seal the cylinders from unintended fluid flow. The prevention mechanism itself creates all necessary forces to prevent the undesired fluid flow to the cylinders. This is accomplished by incorporating appropriate mechanisms within the pump itself.Type: GrantFiled: April 8, 2004Date of Patent: October 21, 2008Assignee: AMS Research CorporationInventors: Gregory J.

Publication number: 20040093030Abstract: A bone anchor assembly having a bone screw and a suture attachment, with the suture attachment threaded to the bone screw with a pair of mating threads that are of the opposite hand from the bone-engaging thread of the bone screw. Overtravel clearance is provided between the bone screw and the suture attachment to permit rotation of the suture attachment with respect to the bone screw at least in the same direction as the direction of engagement of the mating threads. The suture attachment can be an eye bolt or an eye nut. A pilot boss is received in a pilot bore in the engaging portions of the bone anchor and suture attachment. The bone anchor and suture attachment are anodized implant grade titanium material.Type: ApplicationFiled: December 31, 2002Publication date: May 13, 2004Inventors: James E. Cox, Brian P. Watschke, Robert E. Lund, Larry E. Waldack, Richard M. Johnson

Publication number: 20040079208Abstract: The present invention relates to an ultrasonic cutting system including a protective sheet for protecting a cutting blade. The ultrasonic cutting system includes an ultrasonic cutting device, a base plate, and a protective device. The ultrasonic cutting device is configured to cut a material and includes a cutting blade. The base plate is configured to support the material during interaction with the cutting blade. The protective device includes a protective sheet routed over the base plate. During use of the ultrasonic cutting system, the material is routed over the protective sheet prior to interaction with the cutting blade, and the protective sheet is configured to decrease contact between the cutting blade and the base plate.Type: ApplicationFiled: October 25, 2002Publication date: April 29, 2004Applicant: Raymedica, Inc.Inventors: John V.
