Title: Laser pulmonary vein isolation
Inventor: SCHWARTZ YITZHACK
IPC: A61B18/22
Filed: 2003-09-11
Granted: 2012-03-20
Abstract: A catheter introduction apparatus provides an optical assembly for emission of laser light energy. In one application, the catheter and the optical assembly are introduced percutaneously, and transseptally advanced to the ostium of a pulmonary vein. An anchoring balloon is expanded to position a mirror near the ostium of the pulmonary vein, such that light energy is reflected and directed circumferentially around the ostium of the pulmonary vein when a laser light source is energized. A circumferential ablation lesion is thereby produced, which effectively blocks electrical propagation between the pulmonary vein and the left atrium.

Title: Method and apparatus to permit data transmission to traverse firewalls
Inventor: PICHE CHRISTOPHER
IPC: H04L12/56
Filed: 2002-02-19
Granted: 2011-12-20
Abstract: Currently data transmission over the Internet between two client computers where both client computers are protected by firewalls is problematic, since firewalls block incoming packets. A method is provided for permitting packet based data transmission between a first computer protected by a first NAPT or NAT firewall and a second computer protected by a second NAPT or NAT firewall to traverse the first and the second firewalls. The method includes the first and second computers sending first and second data packets to a designated recipient computer. The designated recipient computer communicates the first external address from the first data packet to the second computer and also communicates the second external address from the second data packet to the first computer. The second computer subsequently sends a data packet to the first external address and the first computer sends a data packet to the second external address.
