CATHETER WITH CORONARY SINUS OSTIUM ANCHOR
First Claim
1. A medical device, comprising:
- an elongate body having a proximal portion and a distal portion;
an electrode on the distal portion;
a chamber positioned on the elongate body between approximately 1 cm to 10 cm proximally of the electrode; and
a cryogenic coolant source in fluid communication with the chamber.

Abstract
A method of treating cardiac tissue is provided, including positioning a first chamber of a medical device adjacent an atrial wall; directing a cryogenic coolant into the first chamber; anchoring the first chamber to the atrial wall through cryoadhesion; directing a distal portion of the medical device into the coronary sinus; and positioning a cardiac lead through at least a portion of the coronary sinus with the distal portion. The method may include measuring a temperature of the first chamber; removing the first chamber from the atrial wall once a predetermined threshold temperature of the first chamber is reached; anchoring a second chamber of the medical device to a portion of the coronary sinus; and/or perfusing blood flow through at least a portion of the second chamber.

21. A method of treating a patient, comprising:
-
performing a first procedure, the first procedure including; positioning at least one of a diagnostic element and a therapeutic element of a first medical device adjacent a first tissue region; operating the at least one of a diagnostic element and therapeutic element proximate to the first tissue region; obtaining positional information of the at least one of a diagnostic element and a therapeutic element; generating a first map based on the positional information; and performing a second procedure, the second procedure including; positioning at least one of a diagnostic element and a therapeutic element of a second medical device adjacent a second tissue region; operating the at least one of a diagnostic element and therapeutic element proximate a tissue region; obtaining positional information of the at least one of a diagnostic element and a therapeutic element; generating a second map based on the positional information; registering the second map to the first map. - View Dependent Claims (22, 23, 24)
