Abstract
A catheter system that includes a catheter element sized to pass through blood vessels to an organ of an animal. The distal end portion of the catheter element is capable of assuming and maintaining a curved configuration. A medical element is disposed with respect to the catheter element so as to interact therewith, the medical element being capable of assuming and maintaining a curved configuration. At least one ablating or mapping tool is disposed on the distal end portion of either the medical element or the catheter element, or both, for either mapping or ablating tissue in the organ when the distal end portion of the catheter system is disposed in the organ. The catheter system can include a hand grip for controlling the catheter system.
Claims32
A catheter system comprising:
- a medical element sized to be routed through passageways to an organ of a patient, the medical element having a distal end portion for assuming and maintaining a curved configuration;
- a catheter element operationally disposed with respect to the medical element so as to permit manipulation of the medical element, wherein the catheter element is capable of assuming and maintaining curved configurations such that the distal end portion of the catheter system can be formed into at least one of either an up-going configuration, a down-going configuration, or an out-of-plane configuration;
- at least one medical tool disposed at the distal end portion of at least one of either the catheter element or the medical element wherein the medical tool is used for medical treatment of the organ when the distal end portion of the catheter system is disposed in the patient.
An electrophysiology catheter system comprising:
- a medical element sized to pass through blood vessels to a heart of a patient, wherein the distal end portion of the medical element is capable of assuming and maintaining a curved configuration and defining a plane when in a curved configuration, the distal end portion, when curved, defining a plane;
- a catheter element disposed with respect to the medical element for manipulation of the medical element, the catheter element being capable of assuming and maintaining curved configurations such that the distal end portion of the electrophysiology catheter system is formed into at least one of either an up-going configuration, a down-going configuration, or an out-of-plane configuration;
- at least one of either an ablation tool or a mapping electrode including a receiver disposed at the distal end portion of at least one of either the catheter element or the medical element for one of either ablating a tissue or mapping signals respectively in the heart when the distal end portion of the electrophysiology catheter system is disposed in the heart.
A method of manipulating an electrophysiology catheter comprising:
- curving an electrophysiology catheter into a desired shape;
- bending the distal end portion of a catheter element disposed in a predetermined relationship with respect to the electrophysiology catheter to fix the electrophysiology catheter in a desired position in a heart;
- changing a relative position of the electrophysiology catheter and the catheter element one of either translationally or rotationally to change the position of the electrophysiology catheter in the heart;
- and
- ablating or mapping a portion of the heart.

A catheter comprising:
- a catheter tube having a first proximal end, a first distal end portion, and a lumen extending therethrough, the catheter tube being suitably sized to be inserted into a human body;
- a medical element disposed in a predetermined relationship with respect to the catheter tube, wherein the medical element has a second proximal end and a second distal end portion;
- a medical tool that is disposed at the at least one of either the first distal end portion of the catheter tube or the second distal end portion of the medical element;
- a hand grip adapted to be held by a human user wherein one of either the medical element or the catheter tube is rotationally fixed to the hand grip so that rotation of the hand grip results in corresponding rotation of at least one of either the medical element or catheter tube respectively;
- means for rotating at least one of either the medical element or the catheter tube with respect to the hand grip such that the rotation of the element is controllably rotated with respect to the non-rotating element;
- and
- means for curving at least one of either the distal end portion of the catheter tube or the medical element so that the catheter element is controlled to at least one of either an up-going configuration, a down-going configuration, or an out-of-plane configuration.

A method of manipulating an electrophysiology catheter comprising:
- curving an electrophysiology catheter into a shape which conforms to the shape of a cavity in a heart in which the electrophysiology catheter is disposed so as to place at least one of either an ablating tool or a mapping tool at a first desired position in the heart;
- moving a distal end portion of the electrophysiology catheter to a second position in the heart;
- and
- recurving the electrophysiology catheter into a second shape that conforms to the shape of the cavity in the heart at the second position within the heart so as to place one of either the ablating tool or the mapping tool at a second desired position in the heart.
1 more element
An electrophysiology catheter system comprising:
- an inner element sized to pass through blood vessels to a heart of a patient wherein the inner element is capable of assuming a curved shape at its distal end portion such that the distal end portion of the inner element, when curved, defines a first plane;
- a catheter disposed with respect to the inner element so as to permit manipulation of the electrophysiology catheter system so as to form a stable platform in a cavity of the heart from which a medical element may be extended and used, and wherein the catheter is capable of assuming a curved shape at its distal end portion such that the distal end portion of the catheter, when curved, defines a second plane;
- and
- at least one of either the inner element, the catheter, or the medical element has at least one ablation tool or mapping tool disposed at the distal end portion thereof.
