Patent number: 8083686Abstract: An embodiment of the invention includes a method for acquiring a plurality of tissue samples. The method includes using a device to cut a first tissue sample from an internal tissue tract of a patient and storing the first tissue sample in a container. Without removing the device from the patient, the method further includes using the device to cut a second tissue sample from the internal tissue tract and storing the tissues ample in the container. The method also includes coupling a fluid delivery device to the container to flush the first and second tissue samples from the container.Type: GrantFiled: August 5, 2009Date of Patent: December 27, 2011Assignee: Boston Scientific Scimed, Inc.Inventors: Adam L.

Patent number: 8034034Abstract: A syringe and a method of using the syringe are disclosed. The syringe includes a longitudinal body having proximal and distal ends and including an aperture between the proximal and distal ends. An injectable material, such as an adhesive bone cement, may be loaded into the body of the syringe through the aperture. After the injectable material is inserted, the aperture may be closed by covering the aperture with an aperture cover. The aperture cover may be configured to slide into a position covering the aperture, or the aperture cover may be placed in a position covering the aperture, such as by pivoting about a hinge. After the aperture is closed, the injectable material may be dispensed from the distal end of the syringe body by depressing a plunger. Depressing the plunger may initiate the closing of the aperture, or the aperture may be closed independently of plunger movement.Type: GrantFiled: January 12, 2009Date of Patent: October 11, 2011Assignee: Howmedica Osteonics Corp.Inventors: Brian J. Hess, Richard L. Walker, Jr., Liem T. Vu

Patent number: 5913865Abstract: A supporting structure for a ligating band dispensing device adapted to be coupled to a distal end of an endoscope comprises a substantially cylindrical outer support surface adapted to receive a plurality of ligating bands thereon, wherein the support surface includes a channel extending therethrough from a distal end to a proximal end. The support surface further includes a plurality of shallow slots and deeper slots disposed on the distal end for retaining a trigger string. The shallow slots and deeper slots may be arranged in an alternating fashion, and each of the slots may be narrower than the trigger string to prevent the trigger string from prematurely exiting the slots. The support surface may also include a plurality of axially extending ridges to assist in deployment of the ligating bands by preventing the bands from sliding along the trigger line and facilitating rolling of the bands along the support surface.Type: GrantFiled: May 15, 1998Date of Patent: June 22, 1999Assignee: Scimed Lifesystems, Inc.Inventors: Richard C.
