  • Patent number: 10653320
    Abstract: A volume mapping instrument (20), deployable within a partially or a completely enclosed anatomical volume, employs one or more medical tools (40) with each medical tool (40) being transitional between a deployable structural configuration to orderly position each medical tool (40) within the anatomical volume and a mapping structural configuration to anchor the medical tool (40) against the boundary of the anatomical volume. The volume mapping instrument (20) further employs an optical shape sensor (30) to generate one or more encoded optical signals indicative of a shape of the boundary of the anatomical volume in response to each medical tool (40) being transitioned from the deployable structural configuration to the mapping structural configuration within the anatomical volume. Based on the encoded optical signal(s), a volume mapping module (51) is utilized to map a portion or an entirety of the boundary of the anatomical volume.

  • Publication number: 20160081760
    Abstract: The invention relates to an assisting apparatus (2) for assisting a user in moving an insertion element (11) like a catheter to a target element within, for instance, a person (8). A target element representation representing the target element within the object in its three-dimensional position and three-dimensional orientation and with its size is generated based on a provided target element image. Moreover, a three-dimensional position of the insertion element is tracked, while the insertion element is moved to the target element, and the target element representation and the tracked position of the insertion element are displayed. The three-dimensional position and orientation of the target element relative to the actual position of the insertion element can therefore be shown to the user, while the insertion element is moved to the target element, which allows the user to more accurately and faster move the insertion element to the target element.
