Patent number: 10245026Abstract: The present invention relates to devices, and methods for using the devices, to create and secure a tissue fold during an endoluminal medical procedure. The devices and methods may be used for folding and securing, for example, a fundus wall onto an esophagus wall or esophageal tissue in the region of the lower esophageal sphincter (LES) to reduce the diameter of the esophagus opening in that region. One aspect of the invention includes forming the tissue fold by closing a grasping arm that is pivotably connected to an overtube that has been positioned at the juncture of the fundus wall and esophagus wall. A further aspect of the invention includes tissue clips configured to be inserted and positioned through an endoluminal device.Type: GrantFiled: August 31, 2015Date of Patent: April 2, 2019Assignee: Boston Scientific Scimed, Inc.Inventors: Marc O. Schurr, Kurt Geitz, Robert Sakal, Gerhard F. Buess, Daniel Kalanovic

Patent number: 9955854Abstract: An endoluminal access system for accessing a body lumen includes a guide track which, when in an operative position, extends through a body lumen to a desired location therewithin and a modular device selectively coupleable to the guide track, the modular device including a drive mechanism for engaging the guide track to move the modular device along the guide track within the body lumen. A method of resecting tissue from a site within a body includes the steps of inserting a guide track to a desired location within the body lumen, coupling a modular device to a proximal end of the guide track and actuating a motor mounted within the modular device to drive the modular device distally along the guide track to the site, drawing tissue at the site into the modular device in combination with the steps of coupling together a portion of tissue adjacent to the site, resecting the tissue from the site and actuating the motor to drive the modular device proximally to withdraw the modular device from the body lumen.Type: GrantFiled: April 20, 2015Date of Patent: May 1, 2018Assignee: BOSTON SCIENTIFIC SCIMED, INC.Inventors: German Trabada, Russell F.

Patent number: 8460334Abstract: A modular device for tissue resection includes a housing, a motor, a tissue receiving chamber, a grabbing mechanism and a resection mechanism. The housing includes a guide track receiving lumen extending therethrough. The motor is mounted within the housing. The motor is selectively engageable with a guide track received within the guide track lumen to move the modular device therealong. The tissue receiving chamber is formed within the housing. The grabbing mechanism draws a selected portion of tissue into the tissue receiving chamber. The resection mechanism resects the selected portion of tissue.Type: GrantFiled: December 21, 2006Date of Patent: June 11, 2013Assignee: Boston Scientific Scimed, Inc.Inventors: German Trabada, Russell F.

Patent number: 8137289Abstract: Sample vials and methods of processing the sample vials are provided. The sample vial comprises a vial container, a sample collection chamber within the vial container, a vial cap configured to be mated with the vial container to enclose the collection chamber, an aliquot chamber, which may be carried by the vial cap or the vial container, and a valve mechanism for selectively sealing and unsealing the aliquot chamber from the collection chamber. The method may comprise flowing an aliquot of the sample from the collection chamber while the sample within the collection chamber is isolated from an environment exterior to the vial, sealing the aliquot chamber from the collection chamber to isolate the aliquot sample from the remaining sample portion, and transferring at least some of the remaining sample portion from the collection chamber to a microscope slide while the aliquot chamber is sealed from the collection chamber.Type: GrantFiled: March 4, 2010Date of Patent: March 20, 2012Assignee: Cytyc CorporationInventors: Hal Watts, Robert Sakal
