Publication number: 20170151016Abstract: A system and method are provided for minimally-invasive selective fat removal from a target area by injecting the area with a solution of photo-absorbing nanoparticles and irradiating the injected area with a beam of near infrared (NIR) light. The NIR emission wavelength excites the nanoparticles to melt fat within the target area so that the liquefied fat can be aspirated from the target area. The nanoparticles may be gold nanorods having aspect ratios selected to produce surface plasmon resonance when irradiated with NIR light around 800 nm.Type: ApplicationFiled: December 7, 2016Publication date: June 1, 2017Inventors: Adah ALMUTAIRI, Khalid ALMUTAIRI

Publication number: 20170151017Abstract: Expandable laser catheters for utilizing laser energy to remove obstructions from body passages are described. In one embodiment, the laser catheter includes a shaftway having a distal end including a flexible portion configured in a series of radial folds. Multiple optical fibers, configured to transmit laser energy, extend along the shaftway and are attached to the flexible portion. An inflatable, ring-shaped balloon is attached to the catheter within the flexible portion. In use, the catheter is inserted into a body passage such as an artery, and advanced until the distal end is adjacent to an obstruction. The balloon is inflated to expand the flexible portion and to bring the optical fibers nearer the inner wall of the body passage. Laser energy is directed by the optical fibers toward targeted regions of the obstruction. As the catheter is advanced and the process repeated, a core is formed from the obstruction and contained within the flexible portion.Type: ApplicationFiled: February 10, 2017Publication date: June 1, 2017Inventors: Thomas R. Winston, John M. Neet

Publication number: 20170151019Abstract: Examples of an orthopedic surgical device for use in operating on a target bone and methods for operating a system for use in orthopedic surgery on a bone are generally described herein. An orthopedic surgical device can include an primary positioning block, and a secondary positioning component removably coupled to the primary positioning block. The secondary positioning component can be configured to: engage a prepared engagement feature machined into the target bone, and guide the primary positioning block to a predetermined position on a target bone. The orthopedic surgical device can include a first cutting block configured to: removably couple to the primary positioning block, and guide a cutting tool to cut the target bone.Type: ApplicationFiled: February 9, 2017Publication date: June 1, 2017Applicant: Blue Belt Technologies, Inc.Inventors: Constantinos Nikou, Branislav Jaramaz, Barry M.

Publication number: 20170151021Abstract: The invention generally pertains to a combination of a surgical with a computer-assisted surgery system. The surgical tool may be used as an input device, allowing information to pass from the user to the computer-assisted surgery system, and providing functionality similar to common user interface devices, such as a mouse or any other input device. When used as an input device, it may be used for defining anatomical reference geometry, manipulating the position and/or orientation of virtual implants, manipulating the position and/or orientation of surgical approach trajectories, manipulating the positions and/or orientation of bone resections, and the selection or placement of any other anatomical or surgical feature.Type: ApplicationFiled: February 13, 2017Publication date: June 1, 2017Applicant: MAKO Surgical Corp.Inventor: Arthur E. Quaid, III
