    Abstract: A filler delivery device is configured to place a filler inside a bulge occurring in a body lumen. The filler delivery device includes a frame member configured to be expandable and compressible, and a tubular member through which a catheter for injecting the filler into the bulge is insertable. The tubular member is provided such that, when the frame member is in an expanded state, an open end of the tubular member is directed in a direction intersecting an extending direction of the body lumen. The filler material includes a base gel having flowability with which the filler material flows inside the catheter, and shape retainability with which the filler material stays inside the bulge after being injected from the catheter into the bulge, and a solidification promoting substance that promotes solidification of blood inside the bulge.

  • Patent number: 11197720
    Abstract: A robotic device for performing intracranial procedures, comprising a baseplate for mounting on the subject's skull and a rotatable base element rotating on the baseplate. The rotatable base element has a central opening through which a cannulated needle can protrude such that it can rotate around an axis perpendicular to the baseplate. This cannulated needle is robotically controlled to provide motion into and out of the subject's skull. A flexible needle is disposed coaxially within the cannulated needle, and it is controlled to move into and out of a non-axial aperture in the distal part of the cannulated needle. Coordinated control of the insertion motion of the cannulated and flexible needles, and rotation of the combined cannulated/flexible needle assembly enables access to be obtained to a volume of a region of the brain having lateral dimensions substantially larger than the width of the cannulated needle.
