The force-receiving portion is disposed so that the pressing force applied from the wire generates a moment causing the gripping pieces to be pivoted in a direction causing the gripping pieces to be opened.Type: ApplicationFiled: November 26, 2018Publication date: March 28, 2019Applicant: OLYMPUS CORPORATIONInventor: Noriaki YAMANAKA

Publication number: 20190090895Abstract: A tissue fusing clamp comprises a pair of components pivotably attached, having a component end with a finger loop for manipulation of the components, and each component having a fusing end comprising fusing jaws that are able to be motivated towards one another into a closed position. A depressor depresses tissue between the tissue areas to be fused, resulting in a tightening of the tissue after fusing. The fusing jaws may each comprise a fusing element, such as an ultrasonic transducer or laser, that is in electrical communication with a fusing circuit for providing electrical power to the fusing element as desired by a user. The fusing circuit may be controlled by use of a foot switch or other controller that may be manipulated by the user when it is desired to activate the fusing elements.Type: ApplicationFiled: March 3, 2017Publication date: March 28, 2019Inventor: Ralph Zipper

Publication number: 20190090896Abstract: Methods and devices are provided for preventing binding between components of a drive assembly of a surgical device. In an exemplary embodiment, a surgical device is provided having a ball-and-socket joint that allows bending of various drive shafts relative to the handle without causing movement of a drive rack disposed within the handle. Since the drive rack does not move in response to bending of the shaft, the drive gear and rack will remain aligned thus preventing jamming of the device.Type: ApplicationFiled: November 21, 2018Publication date: March 28, 2019Applicant: Ethicon LLCInventor: Chad P.

Publication number: 20190090901Abstract: Rotational atherectomy devices and systems can remove or reduce stenotic lesions in blood vessels by rotating an abrasive element within the vessel. The abrasive element can be attached to a distal portion of an elongate flexible drive shaft that extends from a handle assembly. In particular embodiments, the handle assembly includes a compressed gas driven turbine member that drives rotation of the drive shaft. The turbine member can be rotatably attached to a carriage that is longitudinally translatable in relation to a housing of the handle assembly. The handle assembly can include a latch mechanism that when actuated allows the carriage to translate to a proximal-most position. While the carriage is in the proximal-most position, an open pathway is created so that a guidewire can be slidably passed through the handle assembly and a lumen of the drive shaft.Type: ApplicationFiled: November 21, 2018Publication date: March 28, 2019Inventors: Cassandra Ann Piippo Svendsen, Charles Anthony Plowe, Albert Selden Benjamin, Paul Joseph Robinson, Evan Leingang
