Abstract: Cryogenic testing systems for testing electronic components such as wafers under cryogenic conditions are provided. The novel designs enable fast throughput by use of a cryogenically maintained test surface to which wafers may be rapidly introduced, cooled, and manipulated to contact testing elements while maintaining high quality cryogenic conditions. Thermal shielding is achieved by floating shields and/or flexible bellows that provide effective thermal shielding of the test environment while enabling manipulation of wafers with a wide range of motion. Also provided are novel door assemblies, chuck configurations, and vacuum plate bases that enable effective maintenance of cryogenic conditions and high throughput.

Abstract: Described herein are systems, devices, and methods for removing material from patient vasculature. In some embodiments, an aspiration device may include a sheath and a catheter slidably disposed within the sheath and defining a lumen. The catheter may include a distal end portion and an elongate portion, the distal end portion being disposable adjacent to a clot, the elongate portion being couplable to a vacuum source that is configured to apply a negative pressure to the lumen to draw the clot into the distal end portion. The distal end portion may include a plurality of sections, each of the plurality of sections having a different cut pattern.

Abstract: An end effector includes first and second members that each have a tissue contacting surface and are moveable relative to one another. The first and second members are configured to clamp tissue therebetween when in an approximated configuration. The tissue contacting surface of the first member defines a first groove. The end effector also includes a bladder that is defined within the first groove and is configured to receive and retain fluid.

Abstract: A surgical sleeve includes a sheath and a contact surface. The sheath defines a lumen therein. The lumen is configured to receive at least a portion of a surgical instrument therein. The sheath is expandable to transition from an un-deployed configuration to a deployed configuration. As the sheath transitions from the un-deployed configuration to the deployed configuration, a length of the lumen increases. The contact surface is disposed along at least a portion of the sheath and is configured to dampen an impact force thereon.

Abstract: An end effector includes first and second jaws, first and second buttresses, and an ultrasonic blade. The first jaw includes a fastener cartridge having a first tissue contacting surface and a plurality of fasteners arranged in rows parallel to a longitudinal axis of the first jaw. The first buttress is attached to the first tissue contacting surface and the second buttress is attached to a second tissue contracting surface of the second jaw. The first and second jaws are movable relative to one another and are configured to grasp tissue therebetween. The ultrasonic is activatable to weld the first buttress to the second buttress and to subsequently cut the welded first and second buttresses and tissue grasped between the first and second jaws.

Abstract: A surgical instrument for surgically joining tissue is disclosed. The surgical instrument includes a handle portion, an endoscopic portion, a pair of jaw members and at least one flexible member attachment structure. The endoscopic portion extends distally from the handle portion and defines a first longitudinal axis. The pair of jaw members is disposed adjacent a distal end of the endoscopic portion and extends generally distally therefrom. At least one of the jaw members is movable with respect to the other between an open position and an approximated position for engaging body tissue therebetween. The flexible member attachment structure is disposed in mechanical cooperation with at least one jaw member and is configured to facilitate the attachment of a flexible member thereto.
