Abstract
Abstract A method for treating tissue comprising the steps of providing a probe including a body having a distal tip, a position sensor for determining a position of the distal tip and a hollow needle movable from the distal tip of the body. The probe is brought into contact with a tissue portion and the hollow needle is moved out of the distal tip of the body and into the tissue portion whereby a therapeutic agent is injected into the tissue portion through the hollow needle.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
172 words
A method for treating tissue comprising the steps of: providing a probe including a body having a proximal end and a distal end, said probe also including a position sensor for determining an instantaneous position and an orientation of said distal end of said body, and a hollow needle movable from said distal end of said body; navigating said probe to a tissue portion using said position sensor of said probe; sensing the instantaneous position and orientation of said distal end of said body using said position sensor; bringing said distal end of said probe into contact with said tissue portion based on the position and orientation of said distal end of said body using said position sensor of said probe; moving said hollow needle out of said distal end of said body and into said tissue portion; injecting a therapeutic agent into said tissue portion through said hollow needle; and urging said hollow needle back into said distal end of said body after injecting said therapeutic agent into said tissue portion.
Claim 2
Independent Claim
172 words
A method for treating tissue comprising the steps of: providing a probe including a body having a proximal end and a distal end, said probe also including a position sensor for determining an instantaneous position and an orientation of said distal end of said body, and a hollow needle movable from said distal end of said body; navigating said probe to a tissue portion using said position sensor of said probe; sensing the instantaneous position and orientation of said distal end of said body using said position sensor; bringing said distal end of said probe into contact with said tissue portion based on the position and orientation of said distal end of said body using said position sensor of said probe; moving said hollow needle out of said distal end of said body and into said tissue portion; injecting a therapeutic agent into said tissue portion through said hollow needle; and urging said hollow needle back into said distal end of said body after injecting said therapeutic agent into said tissue portion.
Claim 3
Dependent Claim
15 words
The method according to claim 1 , including performing functional mapping of said tissue portion.
Claim 4
Dependent Claim
19 words
The method according to claim 2 , including performing said functional mapping and said injecting during the same procedure.
Claim 5
Dependent Claim
27 words
The method according to claim 1 , including determining the position of said distal end of said body by receiving a generated field with said position sensor.
Claim 6
Dependent Claim
15 words
The method according to claim 4 , including generating said generated field with a transmitter.
Claim 7
Dependent Claim
24 words
The method according to claim 5 , wherein generating said generated field with a transmitter includes generating an AC magnetic field with said transmitter.
Claim 8
Dependent Claim
28 words
The method according to claim 1 , further comprising determining the instantaneous position and the orientation including pitch of said distal end of said body of said probe.
Claim 9
Dependent Claim
28 words
The method according to claim 7 , further comprising determining the instantaneous position and the orientation including yaw of said distal end of said body of said probe.
Claim 10
Dependent Claim
28 words
The method according to claim 8 , further comprising determining the instantaneous position and the orientation including roll of said distal end of said body of said probe.
Claim 11
Dependent Claim
31 words
The method according to claim 7 , further comprising determining when said probe is not in motion when said probe is in contact with said tissue portion using said position sensor.
Claim 12
Dependent Claim
31 words
The method according to claim 8 , further comprising determining when said probe is not in motion when said probe is in contact with said tissue portion using said position sensor.
Claim 13
Dependent Claim
31 words
