DELIVERY SYSTEM FOR DELIVERING A MEDICAL DEVICE TO A LOCATION WITHIN A PATIENT'S BODY
First Claim
1. A medical device comprising:
- a sheath having a near portion, a far portion, and at least a first lumen extending therethrough;
a member having a first and second portions and a loop section located therebetween, where the loop section has a shape and is advanceable out of the far portion of the sheath;
a first steering arm moveable on the first portion of the member, where a proximal end of the first steering arm allows manipulation of the a distal end of the first steering arm to alter the shape of loop section;
a second steering arm moveable on the second portion of the member, where a proximal end of the second steering arm allows manipulation of a distal end of the second steering arm to alter the shape of loop section; and
wherein the member is configured such that axial movement of the first and/or second portion of the member through the sheath alters a size of the loop section, and manipulation of the first and/or second steering arms alters the shape of the loop section.

Abstract
Devices, systems and methods are provided for deployment of one or more functional devices, such as therapeutic or diagnostic medical devices, or positioning devices, at various locations relative to a defined operative path. The devices, systems, and methods can include a guide system and a positioning element. The guide system defines the operative path when deployed within a patient'"'"'s body. The positioning element cooperates with the guide system to define one or more positions relative the defined operative path from which the one or more functional devices are deployed. The present inventions allow for the accurate and reliable placement of the one or more functional devices at the one or more positions relative the operative path. In one embodiment, the functional device is an ablation device adapted to ablate cardiac tissue for the treatment of cardiac arrhythmias, such as atrial fibrillation.

10. A method of guiding a medical device along a path in an anatomy of a patient, the method comprising:
-
navigating a sheath towards the anatomy, where the sheath includes a near portion, a far portion, and at least a first lumen extending therethrough, the sheath including a member located within the lumen, the member having a first and second portions extending from a near portion of the sheath, and a loop section located therebetween, where the loop section is advanceable out of the far portion of the sheath; defining a path in the anatomy by advancing at least one portion of the rail to adjust a size of the loop section in the anatomy; altering the profile of the path by manipulating at least one steering arm coupled to a portion of the member, where manipulation of the steering arm alters the loop section to alter the path in the anatomy; advancing the medical device along the loop section to position the medical device along the path in the anatomy. - View Dependent Claims (11, 12, 13)
