Publication number: 20170265938Abstract: A system for ablating internal heart tissue in an ablation pattern on a surface of the tissue within the heart. The system includes an ablation catheter with a distal end having an ablating tip portion operative to allow selective ablation of tissue. A guiding device is engageable with the ablation catheter and includes a tissue anchoring portion operable to engage with tissue proximate to the tissue to be ablated so as to temporarily anchor the guiding device relative to the tissue. Engagement of the guiding device with the ablation catheter operates to assist with guiding the ablating tip portion in moving along the pattern. Various devices and methods of use are further disclosed.Type: ApplicationFiled: June 2, 2017Publication date: September 21, 2017Inventors: Paul A. Spence, Sean Warren, Erica J. Wells, Kurt Dierking, W., Daniel R. Bachman, Landon H. Tompkins

Patent number: 9216055Abstract: A system (60) for ablating internal heart tissue (12) in an ablation pattern (50) on a surface of the tissue within the heart. The system (60) includes an ablation catheter (14) with a distal end having an ablating tip portion (20) operative to allow selective ablation of tissue. A guiding device (62) is engageable with the ablation catheter (14) and includes a tissue anchoring portion (74) operable to engage with tissue proximate to the tissue to be ablated so as to temporarily anchor the guiding device (62) relative to the tissue (12). Engagement of the guiding device (62) with the ablation catheter (14) operates to assist with guiding the ablating tip portion (20) in moving along the pattern (50). Various devices and methods of use are further disclosed.Type: GrantFiled: August 5, 2010Date of Patent: December 22, 2015Assignee: SCR Inc.Inventors: Paul A. Spence, Sean P. Warren, Erica J.

Patent number: 8894667Abstract: An endoscopic closure device comprises: a coupling member; a helical needle mounted to the coupling member and carrying a suture; and a plurality of grasping needles, each of said plurality of grasping needles moveable between a storage position and a deployed position. The plurality of grasping needles is configured to be (a) advanced in the storage position into a luminal defect, (b) moved into the deployed position, and (c) then refracted from the luminal defect, thus pulling and drawing tissue surrounding the luminal defect together. Then, upon rotation of the coupling member and the helical needle, the helical needle is driven into and pierces the tissue, carrying the suture through the tissue.Type: GrantFiled: March 9, 2011Date of Patent: November 25, 2014Assignee: University of Louisville Research Foundation, Inc.Inventors: Farid Kehdy, Guruprasad A. Giridharan, Erica J. Wells, Kenny J. King, Lindsay N. Strotman, William R. Ross
