Abstract
Abstract Methods, systems and devices for establishing communication between organs and/or tissue lumens. The devices include catheters having magnetized distal ends which are configured to magnetically couple to each other such that a coaxial alignment is established between two or more catheters. The systems include two or more the subject catheters. The methods include use of the catheters and magnetically coupling them to establish a continuous passageway between them.

Claims Analysis
Total Claims: 23
Claim 1
Independent Claim
47 words
A system comprising: a first percutaneous catheter comprising a magnetized distal end; and a second percutaneous catheter comprising a magnetized distal end; wherein the magnetized distal ends are configured and have magnetic polarities wherein magnetic coupling between the distal ends provides a coaxial alignment between the catheters.
Claim 2
Independent Claim
47 words
A system comprising: a first percutaneous catheter comprising a magnetized distal end; and a second percutaneous catheter comprising a magnetized distal end; wherein the magnetized distal ends are configured and have magnetic polarities wherein magnetic coupling between the distal ends provides a coaxial alignment between the catheters.
Claim 3
Dependent Claim
16 words
The system of claim 1 , wherein each magnetized distal end comprises at least one magnet.
Claim 4
Dependent Claim
23 words
The system of claim 1 , wherein each magnetized distal end comprises a plurality of magnetic segments wherein adjacent segments are oppositely polarized.
Claim 5
Dependent Claim
25 words
The system of claim 3 , wherein the plurality of magnetic segments are axially arranged with respect to the longitudinal axis of the catheter lumen.
Claim 6
Dependent Claim
27 words
The system of claim 1 , wherein the magnetized distal ends are configured whereby the catheters are only able to magnetically couple in a single rotational orientation.
Claim 7
Dependent Claim
27 words
The system of claim 1 , wherein the magnetized distal ends are configured whereby the catheters are able to magnetically couple in a plurality of rotational orientations.
Claim 8
Dependent Claim
17 words
The system of claim 1 , wherein at least one of the catheters comprises a tissue-penetrating member.
Claim 9
Dependent Claim
20 words
The system of claim 7 , wherein at least one of the catheters is configured to receive the tissue-penetrating member.
Claim 10
Dependent Claim
18 words
The system of claim 1 , further comprising at least one additional catheter having a magnetized distal end.
Claim 11
Dependent Claim
15 words
A kit comprising: the system of claim 1 ; and Instructions for using the system.
Claim 12
Dependent Claim
18 words
The kit of claim 10 , further comprising at least one additional catheter having a magnetized distal end.
Claim 13
Dependent Claim
32 words
The system of claim 1 , wherein the magnetized distal ends are configured to be concentrically positioned with respect to each other when the distal ends are in contact with each other.
Claim 14
Independent Claim
49 words
A method comprising: delivering a first percutaneous catheter comprising a magnetized distal end to a target site within a body; delivering a second percutaneous catheter comprising a magnetized distal end to the target site; and magnetically coupling the distal ends wherein a coaxial alignment is established between the catheters.
Claim 15
Independent Claim
49 words
A method comprising: delivering a first percutaneous catheter comprising a magnetized distal end to a target site within a body; delivering a second percutaneous catheter comprising a magnetized distal end to the target site; and magnetically coupling the distal ends wherein a coaxial alignment is established between the catheters.
Claim 16
Dependent Claim
18 words
The medical method of claim 13 , further comprising penetrating a tissue structure positioned between the distal ends.
Claim 17
Dependent Claim
54 words
The medical method of claim 14 , wherein the first catheter is delivered within a first tissue chamber or lumen and the second catheter is delivered within a second tissue chamber or lumen adjacent said first tissue chamber or lumen, and wherein penetrating the tissue comprises establishing communication between the first and second catheters.
Claim 18
Dependent Claim
71 words
The method of claim 13 , wherein the method further comprises: placing the distal end of the first percutaneous catheter on one side of a tissue structure at the target site; and placing the distal end of the second percutaneous catheter on the other side of the tissue structure at the target site so that the tissue structure is positioned between the distal ends of the first and second percutaneous catheters.
Claim 19
Dependent Claim
17 words
The method of claim 13 , wherein the method is a method of ventricular septal defect repair.
Claim 20
Independent Claim
53 words
A device comprising: a catheter having a distal end comprising a tissue-penetrating member, wherein said distal end is configured for the axial passage of an object and/or fluid there from; and a magnetic element positioned at the distal end wherein the magnetic element comprises at least one magnet having a forward facing surface.
Claim 21
Independent Claim
53 words
A device comprising: a catheter having a distal end comprising a tissue-penetrating member, wherein said distal end is configured for the axial passage of an object and/or fluid there from; and a magnetic element positioned at the distal end wherein the magnetic element comprises at least one magnet having a forward facing surface.
Claim 22
Dependent Claim
22 words
The device of claim 18 , wherein the magnetic element is configured to be disengagable from the distal end of the catheter.
Claim 23
Dependent Claim
