Abstract: An end effector has three degrees of freedom in operation: (1) opening and closing of the jaws, (2) adjustable articulation of the jaw plane relative to the longitudinal axis, and (3) rotation of the jaw assembly, regardless of its articulation, about the longitudinal axis. A split yoke assembly is coupled to rotatable jaw mounts, which in turn are coupled to the jaws. A pushrod is configured to open and close the jaws, and cables coupled to the rotatable jaw mounts cause articulation of the jaw plane.

Abstract: Apparatus, systems and methods for use thereof are disclosed. An example apparatus includes a filter having an expandable frame and a semipermeable membrane coupled to the expandable frame. The expandable frame has a cone-shape in an expanded position. An apex of the expandable frame is arranged at the filter's first end. The expandable frame has a plurality of polygonal supports coupled together at the apex and that are radially biased outward such that in the expanded position the polygonal supports are spaced apart at a second end of the filter with the semipermeable membrane extending therebetween. The semipermeable membrane covers an area defined by the polygonal supports. A plurality of struts each have a first and second end, and the first end of each of the struts is coupled to a second end of the expandable frame. A stent is coupled to each of the second ends of the struts.

Abstract: A device for removing an obstruction from a lumen in a human or animal subject may include an inflatable balloon. The inflatable balloon may include a proximal tapered portion having a proximal taper angle, a central portion, and a distal tapered portion having a distal taper angle that is greater than the proximal taper angle. The balloon may also include at least one eversion feature on the proximal tapered portion and/or the distal tapered portion. The eversion feature may facilitate preferential eversion of the distal tapered portion into an inside of the balloon without the proximal tapered portion collapsing. Preferential eversion of the distal tapered portion may be provided by the differences in the distal and proximal taper angles and by one or more of a number of different types of eversion features.

Abstract: An endoscopic stone-extraction device is provided comprising a support filament (910) comprising an end portion, a sheath (930) comprising a lumen (940), wherein the support filament (910) is disposed in the lumen (940) such that the sheath (930) is slideable with respect to the support filament (910), and a handle comprising an actuator (1700). Movement of the actuator (1700) in a first direction retracts the sheath (930) and causes a shape to expand outside the lumen (940). Movement of the actuator (1700) in a second direction advances the sheath (930) and causes the shape to at least partially collapse inside the lumen (940). Other embodiments are provides, and any of these embodiments can be used alone or in combination.
