Abstract
A method, device and system having dual catheters each containing a large circular, circumferential and oppositely polar magnet at each catheter tip.
Claims34
A catheter system comprising:
- first and second catheters, each catheter having a distal end including a magnet, said magnet of said first catheter is the polar opposite of said magnet used with said second catheter, each catheter having a lumen, and said lumens are substantially aligned when said catheters are magnetically paired.
A medical system comprising:
- first and second instruments, each instrument having a distal end including a magnet, said magnet of said first instrument is the polar opposite of said magnet used with said second instrument, and magnets are substantially aligned when said instrument are magnetically paired.
A method of advancing a device from a first lumen to a spaced apart second lumen comprising the steps of:
- providing first and second catheters, each catheter having a distal end including a magnet, the magnet of the first catheter is the polar opposite of the magnet used with the second catheter, each catheter having a lumen;
- and advancing said distal end of each catheter close to one another until said magnets pair said ends together to aligned said lumens so as to permit the passage of the device from said first lumen to said second lumen.
