Abstract
Methods of delivering a medical device to a point of treatment in a body vessel are described. In methods according to the invention, a reference device comprising a plurality of reference markings and a medical device comprising at least one position marker are provided. The reference device is associated with an external surface of the patient in a region adjacent the body vessel in which the medical device is to be implanted. A target implant site is determined and correlated with at least one selected reference marking on the reference device. The medical device is percutaneously advanced to the target implant site by visually referencing the at least one selected reference marking and the at least on position marker using an appropriate imaging system.

A method for delivering a medical device to a point of treatment in a body vessel of a patient, comprising:
- providing an imaging system;
- providing a medical device comprising at least one position marker visible with the imaging system;
- providing a reference device comprising a plurality of reference markings;
- associating the reference device with an external surface of said patient in a region adjacent said body vessel;
- determining a target implant site in said body vessel;
- correlating the target implant site with at least one selected reference marking of the plurality of reference markings;
- and
- percutaneously advancing the medical device to the target implant site by visually referencing the at least one selected reference marking and the at least one position marker with the imaging system.
A method for delivering a medical device to modify fluid flow in a body vessel of a patient, comprising:
- providing an imaging system;
- providing a valve device comprising at least one position marker visible with the imaging system;
- providing a reference device comprising a plurality of reference markings;
- associating the reference device with an external surface of said patient in a region in which the prosthetic valve is to be implanted;
- determining a valve location of at least one insufficient valve in said body vessel;
- determining a target implant site in said body vessel relative to the valve location;
- correlating the target implant site with at least one reference marking of the plurality of reference markings;
- and
- percutaneously advancing the valve device to the target implant site by visually referencing the at least one reference marking and the at least one position marker with the imaging system.
A method for delivering a medical device in a body vessel of a patient;
- comprising:
- providing an imaging system;
- providing a valve device comprising at least one position marker visible with the imaging system;
- associating a reference device with an external surface of said patient in a region in which the prosthetic valve is to be implanted, the reference device including a plurality of reference markings visible with the imaging system;
- determining an anatomical point of reference;
- correlating the anatomical point of reference with a first reference marking of the plurality of reference markings;
- and
- percutaneously advancing the valve device to a target implant site by visually referencing a second reference marking and the at least one position marker with the imaging system, the second reference marking spaced from the first reference marking by a predetermined distance.
