20080221439 | Tools for use with moving organs - A sensor senses a phase of cyclic activity of a portion of a subject's body. A control unit, in a first cycle of the cyclic activity, moves a portion of a tool, in a given direction, in response to the sensor sensing that the cyclic activity is at a first given phase thereof. The control unit, following the given phase and prior to an occurrence of the given phase in a subsequent cycle, inhibits the tool's movement. The control unit in a second cycle, subsequent to the inhibiting, moves the tool in the given direction, in response to the sensor sensing that the second cycle is at the given phase, without moving the tool in an opposite direction, between (a) moving the tool in the given direction in the first cycle, and (b) moving the tool in the given direction in the second cycle. Other embodiments are also described. | 09-11-2008 |
20080221440 | Imaging and tools for use with moving organs - Apparatus is described for use with a portion of a subject's body that moves as a result of cyclic activity of a body system. An imaging device acquires a plurality of image frames of the portion. A sensor senses a phase of the cyclic activity. A medical tool performs a function with respect to the portion. A control unit generates a stabilized set of image frames of the medical tool disposed within the portion, actuates the tool to perform the function or move, in response to the sensor sensing that the cyclic activity is at a given phase thereof, and inhibits the tool from performing the action or moving in response to the sensor sensing that the cyclic activity is not at the given phase. A display facilitates use of the tool by displaying the stabilized set of image frames. Other embodiments are also described. | 09-11-2008 |
20080221442 | Imaging for use with moving organs - Apparatus is described for imaging a portion of a body of a subject that moves as a result of cyclic activity of a body system of the subject and that also undergoes additional motion. An imaging device acquires a plurality of image frames of the portion. A sensor senses a phase of the cyclic activity of the body system. A control unit generates a stabilized set of image frames of the portion by identifying a given phase of the cyclic activity, and outputting a set of the image frames corresponding to image frames of the portion acquired during the given phase, and by image tracking at least the set of image frames to reduce imaged motion of the portion associated with the additional motion. A display displays the stabilized set of image frames of the portion. Other embodiments are also described. | 09-11-2008 |
20090306547 | STEPWISE ADVANCEMENT OF A MEDICAL TOOL - Apparatus is provided, including a sensor for sensing a phase of cyclic activity of a subject's body system. A tool modulator includes a gate configured:

20140111541 | AUTOMATIC IDENTIFICATION OF A TOOL - Apparatus and methods are described for use with a portion of a body of a subject including acquiring a plurality of images of the portion, and displaying one of the images. In response to receiving an input that is indicative of a given location within the image, an indication of a region within the portion is generated on the image. In response to receiving a further input, a dimension of the region that is indicated within the image is modified. In response thereto, at least one tool that is suitable for being placed at the region is identified, and/or a dimension of at least one tool that is suitable for being placed at the region is identified. An output is generated is response to the identification. Other applications are also described. | 04-24-2014 |
20140114308 | STABILIZED ENERGY-DELIVERY PROCEDURES - Apparatus and methods are described for use with a portion of a subject's body that moves as a result of cyclic activity, including sensing a phase of the cyclic activity. In a first cycle of the activity, in response to sensing that the activity is at a given phase, a therapeutic tool is actuated to apply a treatment to the portion by applying energy to the portion. Following the given phase in the first cycle and prior to an occurrence of the given phase in a subsequent cycle, the tool is inhibited from applying energy to the portion. In a second cycle of the activity, subsequent to the inhibiting of the application of energy to the portion, and in response to sensing that the second cycle is at the given phase, the tool is actuated to apply energy to the portion. Other applications are also described. | 04-24-2014 |
20140114333 | TREATMENT OF AN OCCLUSION OF A BLOOD VESSEL - Apparatus and methods are described including sensing a phase of a cyclic activity of a subject. In a first cycle of the cyclic activity, at a given phase of the cycle, movement of a distal portion of a tool toward an occlusion in the subject's blood vessel is allowed. Following the given phase in the first cycle, and prior to an occurrence of the given phase in a subsequent cycle, movement of the tool is inhibited. In a second cycle of the cyclic activity, at the given phase of the cycle, the occlusion is at least partially penetrated by the tool, by allowing movement of the distal portion of the tool through at least a portion of the occlusion. Other applications are also described. | 04-24-2014 |
20150283319 | AUTOMATIC CONTRAST-AGENT INJECTION DETECTION - Apparatus and methods are described, for use with a contrast agent that is injected into a blood vessel of a subject. The apparatus and methods include acquiring a plurality of image frames of the subject's blood vessel, acquisition of the image frames commencing prior to injection of the contrast agent into the blood vessel. Using at least one processor, one of the image frames is automatically identified as being an image frame in which an angiographic sequence commenced, by determining that, in the image frame, there is a change in a characteristic of the image frame relative to at least one image frame acquired prior to the image frame that is indicative of a presence of contrast agent within the image. An output is generated at least partially in response thereto. Other applications are also described. | 10-08-2015 |
