Magnetic introducer systems and methods

Abstract

Systems and methods for placing a treatment device within a patient involve advancing a magnetic first introducer into the patient, advancing a magnetic second introducer into the patient, coupling the first introducer with the second introducer via magnetic force, and using the introducer devices to place a treatment device at a desired location within the patient. Optionally, such techniques involve visualization of the introducers or treatment devices during the procedure.

We claim: 
     
         1 . A method for placing a treatment device at a location within a patient, comprising:
 advancing a first introducer into the patient, wherein the first introducer comprises a distal portion and a proximal portion, the distal portion of the first introducer comprising a coupling member;   advancing a second introducer into the patient, wherein the second introducer comprises a distal portion and a proximal portion, the distal portion of the second introducer comprising a coupling member;   coupling the coupling member of the first introducer and the coupling member of the second introducer;   moving the first introducer and the second introducer while the coupling member of the first introducer and the coupling member of the second introducer are coupled, so as to place a treatment device that is coupled with the proximal portion of the first introducer at a location within the patient.
