Pre-deployment positioning of an implantable device within a moving organ

A method for deploying an implantable tool at a pre-designated implantation location within a blood vessel of a subject, comprising:

• advancing the implantable tool to the pre-designated implantation location;
• while the implantable tool, in a non-deployed configuration, is disposed at the pre-designated implantation location, acquiring a plurality of image frames of the implantable tool, during respective phases of a cardiac cycle of the subject;
• using at least one computer processor, by analyzing at least some of the image frames, automatically determining that, due to variations in blood flow within the blood vessel at the respective phases of the subject's cardiac cycle, the implantable tool shifts with respect to the blood vessel, moving from the pre-designated implantation location by a given distance in a first direction;
• using the at least one computer processor, in order to account for movement of the implantable tool by the given distance, determining a deployment location, at which to deploy the implantable tool, the deployment location being distant from the pre-designated implantation location in a second direction, the second direction being an opposite direction to the first direction;
• and
• using the at least one computer processor, automatically generating an output indicating the determined deployment location.
