Pre-deployment positioning of an implantable device within a moving organ
First Claim
1. 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.

Abstract
Apparatus and methods are described for deploying an implantable tool at an implantation location of a blood vessel. The tool is placed at the implantation location in a non-deployed configuration. A plurality of image frames are acquired of the non-deployed tool at the implantation location, during respective phases of the vessel'"'"'s motion cycle. A stabilized image stream is generated of the non-deployed tool at the implantation location. It is determined based upon the stabilized image stream of the non-deployed tool that, during the vessel'"'"'s motion cycle, the tool moves from the implantation location by a given distance in a first direction. Movement of the tool by the given distance is accounted for, by deploying the tool at a deployment location that is distant from the implantation location in the opposite direction to the first direction. Other embodiments are also described.

9. Apparatus comprising:
-
an implantable tool configured to be advanced to a pre-designated implantation location of a blood vessel of a subject, while the implantable tool is in a non-deployed configuration; an image acquisition device configured, while the implantable tool is disposed at the pre-designated implantation location in a non-deployed configuration, to acquire a plurality of image frames of the implantable tool, during respective phases of a cardiac cycle of the subject; a display; and at least one computer processor configured to; determine, by analyzing at least some of the image frames, 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, account for movement of the implantable tool by the given distance, by 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 that is an opposite direction to the first direction, and drive the display to display an output indicating the determined deployment location. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
