Abstract
A catheter for endovascular treatment of a blood vessel includes a treatment portion, a proximal magnetic array positioned proximal to the treatment portion, and a distal magnetic array positioned distal to the treatment portion. Each of the proximal magnetic array and the distal magnetic array include a first magnetic segment having a first polarity, and a second magnetic segment having a second polarity opposite to the first polarity, wherein the second magnetic segment is disposed adjacent to the treatment portion.
Claims21
A catheter for endovascular treatment of a blood vessel, the catheter comprising:
- a treatment portion, a proximal magnetic array positioned proximal to the treatment portion, and a distal magnetic array positioned distal to the treatment portion, wherein each of the proximal magnetic array and the distal magnetic array comprise:
- a first magnetic segment comprising a first contiguous block of like-polarity magnets, said first magnetic segment having a first polarity;
- and
- a second magnetic segment comprising a second contiguous block of like-polarity magnets, said second magnetic segment having a second polarity opposite to the first polarity, wherein the second magnetic segment is disposed adjacent to the treatment portion.
A system for endovascular treatment of a blood vessel, the system comprising:
- a first catheter and a second catheter, each of the first catheter and the second catheter comprising a treatment portion, a proximal magnetic array positioned proximal to the treatment portion, and a distal magnetic array positioned distal to the treatment portion, wherein each proximal magnetic array and each distal magnetic array comprises:
- a first magnetic segment comprising a first contiguous block of like-polarity magnets, said first magnetic segment having a first polarity;
- and
- a second magnetic segment comprising a second contiguous block of like-polarity magnets, said second magnetic segment having a second polarity opposite to the first polarity of the first magnetic segment, the second magnetic segment is disposed adjacent to the treatment portion,
- wherein the second polarity of second magnetic segment of the first catheter has a same polarity orientation as the second magnetic segment of the second catheter when the first catheter and the second catheter are aligned for endovascular treatment.
A method for endovascular treatment of a blood vessel comprising:
- advancing a first catheter within a first blood vessel to a treatment location;
- aligning a treatment portion of the first catheter with the treatment location, wherein the first catheter comprises:
- a proximal magnetic array positioned proximal to the treatment portion, and a distal magnetic array positioned distal to the treatment portion, wherein each of the proximal magnetic array and the distal magnetic array comprises:
- a first magnetic segment comprising a first contiguous block of like-polarity magnets, said first magnetic segment having a first polarity;
- and
- a second magnetic segment comprising a second contiguous block of like-polarity magnets, said second magnetic segment having a second polarity opposite to the first polarity, the second magnetic segment being disposed adjacent to the treatment portion;
- and
- modifying the first blood vessel at the treatment location with the treatment portion.
