Publication number: 20090299364Abstract: An ablation device for ablating tissue having an outer wall and an inner wall, approximately parallel and concentric with said outer wall, defining an inner fluid chamber and an outer low pressure chamber. Each of the outer wall and the inner wall have an edge defining an open face of the fluid chamber and the low pressure chamber. An ablative element is contained within the fluid chamber. A source of low pressure is coupled to the low pressure chamber. When the edge of the outer wall and the edge of the inner wall contact a surface, the ablation device is at least partially secured to the surface by low pressure created in the low pressure chamber by the source of low pressure. The fluid chamber is at least partially fluidly isolated from the low pressure chamber when the ablation device is at least partially secured to the surface.Type: ApplicationFiled: April 21, 2009Publication date: December 3, 2009Applicant: Medtronic, Inc.Inventors: Kester Batchelor, David Francischelli, Tom Daigle, Dan Haeg, Paul Rothstein, Adam Podbelski, Sarah Ahlberg, Steve Ramberg, Tom Conway

Publication number: 20080108878Abstract: An improved tissue engagement device such as a suction stabilizer or retractor. The stabilizer or retractor is provided with one or more suction pods mounted to the distal end of a flexible arm. The flexible arm is coupled to a base assembly, which attaches the arm to an associated retractor or other structure that is fixedly located relative to the operative site. The base assembly includes a fixed portion, which is coupled to the retractor or other fixed mounting point and a rotatable turret, allowing rotation of the arm relative to the fixed portion of the base assembly. A tensioning mechanism mounted to the turret applies tension to compress the turret around a corresponding pivot mounted to the fixed portion of the base to rotationally lock the turret and to lock the arm in its current configuration.Type: ApplicationFiled: December 21, 2007Publication date: May 8, 2008Inventors: Jack Goodman, Tom Daigle, Douglas Gubbin, David Kim

Publication number: 20060195083Abstract: A hemostat-type device for ablative treatment of tissue, particularly for treatment of atrial fibrillation, is constructed with features that provide easy and effective treatment. A swiveling head assembly can allow the jaws to be adjusted in pitch and roll. Malleable jaws can permit curved lesion shapes. A locking detent can secure the jaws in a closed position during the procedure. An illuminated indicator provides confirmation that the device is operating. A fluid delivery system simplifies irrigated ablation procedures.Type: ApplicationFiled: April 26, 2006Publication date: August 31, 2006Inventors: Scott Jahns, David Francischelli, Alison Lutterman, James Keogh, Roderick Briscoe, William O'Neill, Jack Goodman, Tom Daigle, Paul Rothstein, Adam Podbelski, Stephen Roddy, David Kim, Mark Bilitz
