The FUS pressure field highly amplifies the power density, highly amplifies the intensity, sharpens the diameter, and reduces the full width at half maximum (FWHM) of the laser beam. The FUS pressure field keeps the laser beam's lensing power positive, with small fluctuations, as long as the ultrasound wave is coaxially propagated with the laser beam. | 2021-05-06 |
| 20210128239 | MEDICAL DEVICES AND METHODS INCORPORATING FRUSTRATED TOTAL INTERNAL REFLECTION FOR ENERGY-EFFICIENT SEALING AND CUTTING OF TISSUE USING LIGHT ENERGY - A medical instrument includes two jaw members, at least one of which creates conditions of frustrated total internal reflection at a tissue-contacting surface when tissue is grasped between the two jaw members. The first jaw member may include an optical element having a tissue-contacting surface. The medical instrument also includes a light source that provides a light beam for sealing tissue. The light source is positioned so that the light beam is totally internally reflected from an interface between the tissue-contacting surface and air when tissue is not grasped by the jaw members. When tissue is grasped by the jaw members, at least a portion of the light beam is transmitted through that portion of the tissue-contacting surface that is in contact with the tissue. The light source may be movably coupled to a jaw member to scan the light beam and/or to change the incident angle based on optical properties of the tissue. | 2021-05-06 |
| 20210128240 | SYSTEM AND DEVICE FOR TREATING BODY TISSUE - A medical device that includes a hand piece; a beam fiber; and a beam disperser located at a distal end of the beam fiber through which beam energy is dispersed. The beam disperser includes one face, or a plurality of substantially planar faces through which the beam energy is dispersed. | 2021-05-06 |
| 20210128241 | ASYMMETRICAL BALLOON FOR LITHOPLASTY DEVICE AND METHOD - A catheter system for treating a treatment site within or adjacent to a vessel wall within a body of a patient includes an energy source, a balloon, and an energy guide. The energy source generates energy. The balloon includes a balloon wall that defines a balloon interior. The balloon is configured to retain a balloon fluid within the balloon interior. The balloon is selectively inflatable with the balloon fluid to expand to an inflated state, wherein when the balloon is in the inflated state the balloon wall is configured to be positioned substantially adjacent to the treatment site. The balloon further includes a balloon central axis that extends through a geometric center of the balloon when the balloon is in the inflated state. The energy guide selectively receives energy from the energy source and guides the energy from the energy source into the balloon interior. The energy guide including a guide distal end that is positioned on the balloon central axis when the balloon is in the inflated state. | 2021-05-06 |
