Abstract: An ultrasonic tool system with a console and a tip that has a distal end that when vibrated vibrates both longitudinally and torsionally. The console applies a drive signal to the drivers that vibrate the tip that is at a longitudinal mechanical cancellation frequency. Consequently, when the tip is vibrated, at the distal end the longitudinal component of a first resonant mode of the tip cancel out the longitudinal component of the second resonant move of the tip so the distal end of the tip engages in vibrations that substantially torsional and only minimally longitudinal.

Abstract: A buttress is applied to an end effector of a surgical stapler. The buttress is loaded on a platform of a buttress applier cartridge. The end effector is closed upon the platform. An adhesive layer of the buttress secures the buttress to the end effector. The buttress is thus adhered to the end effector when the end effector is opened. The end effector is then actuated on tissue of a patient, thereby stapling the buttress to the tissue.

Abstract: Systems and methods related to polymer foams are generally described. Some embodiments relate to compositions and methods for the preparation of polymer foams, and methods for using the polymer foams. The polymer foams can be applied to a body cavity and placed in contact with, for example, tissue, injured tissue, internal organs, etc. In some embodiments, the polymer foams can be formed within a body cavity (i.e., in situ foam formation). In addition, the foamed polymers may be capable of exerting a pressure on an internal surface of a body cavity and preventing or limiting movement of a bodily fluid (e.g., blood, etc.).

Abstract: A method and prosthesis is provided for percutaneous repair of an anatomical defect, such as an inguinal hernia. The method involves percutaneously accessing the inguinal canal of a patient. Following hernia reduction, if required, the hernia defect may be accessed and repaired percutaneously from within the inguinal canal. An implantable prosthesis may be percutaneously delivered into the inguinal canal. The prosthesis may be advanced along the inguinal canal from the percutaneous entry location to the defect site, where it may be deployed over and/or within the defect. A biocompatible foam material may be percutaneously delivered into the inguinal canal to reduce and/or repair the hernia defect. The foam may fill and solidify in the canal to prevent abdominal viscera from reentering the canal. Ablative therapy may be performed within the inguinal canal to cause a fibrotic response resulting in scar tissue formation and/or tissue shrinkage that narrows the canal.

Abstract: A system for registering operating space includes a back bracing, a computer system and a robotic arm. The back bracing includes positioning marks which can be imaged in a computer tomography (CT) image, and the back bracing is used to be worn by a patient. The computer system computes image coordinates of the positioning marks in an image space. A base of the robotic arm is connected to the back bracing in an operating space after the CT image is generated. The robotic arm contacts the positioning marks in the operating space and meanwhile the computer system obtains arm coordinates of the robotic arm in an arm space. The computer system generates conversion models among the image space, the operating space, and the robot arm space according to the image coordinates and the arm coordinates.
