  • Publication number: 20240269288
    Abstract: Methods of non-contact lithotripsy are disclosed, wherein photonic nanoparticles are delivered in the vicinity of kidney stones, e.g. within a kidney. The nanoparticles then are irradiated with non-ionizing electromagnetic radiation to activate the nanoparticles and fragment the stone. In preferred embodiments, the nanoparticles are placed effectively into contact with the kidney stone, via functionalizing the particles with ligands that will adhere to the known or anticipated chemical composition of the stone surface. A combination of a kidney stone and a photonic nanoparticle in its vicinity or adhered thereto at its surface also is disclosed.

  • Publication number: 20220378474
    Abstract: A cannula is provided that includes a head portion that defines a proximal opening sized to receive one or more surgical instruments; an elongated inner tube rigidly fastened to the head portion defines an elongated conduit; a surgical instrument can be inserted within the conduit; an elongated overtube rigidly fastened to the head portion is coaxially aligned with the inner tube and extends about a portion of the inner tube; an inner wall of the overtube is spaced apart from an outer wall of the inner tube; sensors are disposed on the overtube to provide an indication of forces applied to the outer wall of the overtube in a direction generally transverse to the longitudinal dimension of the overtube.
