Patent number: 9289197Abstract: Methods and apparatus for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being with an anchor, a sealing plug and a filament connecting the anchor and sealing plug are disclosed. The methods and apparatus provide for automatic tamping of the sealing plug. In addition, torque required to tamp the sealing plug is automatically sensed and gear ratios of an automatic tamping device are automatically changed in response to sensed changes in torque. A planetary transmission may be used to automatically change gear ratios in response to the changes in torque.Type: GrantFiled: June 5, 2013Date of Patent: March 22, 2016Assignee: ST. JUDE MEDICAL PUERTO RICO LLCInventor: Andrew Thomas Forsberg

Patent number: 8518075Abstract: The present invention is directed to methods and apparatus for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being with an anchor, a sealing plug and a filament connecting the anchor and sealing plug. The method and apparatus provide a magazine fed tamping system for automatic tamping and/or cinching of the sealing plug when the apparatus is withdrawn from the puncture site. The automatic tamping and/or cinching is facilitated by transducing a motive force generated by the withdrawal of the apparatus into a tamping and/or cinching force.Type: GrantFiled: April 2, 2010Date of Patent: August 27, 2013Assignee: St. Jude Medical Puerto Rico LLCInventor: Andrew Thomas Forsberg

Patent number: 8465517Abstract: A method and apparatus for sealing a puncture or incision formed percutaneously in tissue separating two internal portions of the body of a living being with an anchor, a sealing plug and a filament connecting the anchor and sealing plug. The method and apparatus provide for a tamping device that is coilable in some configurations and stiff and straight in other configurations.

Patent number: 8382795Abstract: The present invention provides a method and apparatus for sealing a subcutaneous tissue puncture. The method and apparatus increases the reliability of device function by creating a multi-level anchor nest in a carrier tube of a tissue puncture closure device. The multi-level nest allows an insertion sheath or other deployment member to slide between the carrier tube and the anchor to rotate and deploy the anchor within an artery or other lumen.Type: GrantFiled: August 27, 2009Date of Patent: February 26, 2013Assignee: St. Jude Medical Puerto Rico LLCInventors: Andrew Thomas Forsberg, Loran Paprocki

Patent number: 7717875Abstract: A hydraulically assisted actuator in a handle connects with a catheter having a deflectable distal ablation tip. The hydraulic actuator translates small mechanical movement by a clinician into large travel movements of connected steering cables and increased tension in the ablation tip for greater deflection. The hydraulic system further dampens the return of the ablation tip from a deflected position to an equilibrium position. The hydraulic actuation system is also incorporated into a set of foot pedals.Type: GrantFiled: July 20, 2004Date of Patent: May 18, 2010Assignee: St. Jude Medical, Atrial Fibrillation Division, Inc.Inventors: John Christian Knudson, Andrew Thomas Forsberg
