20220257255 | MEDICAL SLIDING SHAFT INSTRUMENT - A medical sliding shaft instrument includes a tool element carrier, a tubular sliding shaft surrounding the tool element carrier and defining a sliding direction, and an actuating device for moving the sliding shaft relative to the tool element carrier in the distal direction. At least one tool element is arranged or movably mounted on the distal end of the tool element carrier. The at least one tool element is arranged or formed so as to cooperate with a distal end region of the sliding shaft in such a way that the at least one tool element is moved as a result of a movement of the sliding shaft in the distal direction. The sliding shaft instrument further comprises a locking device for blocking a movement of the sliding shaft relative to the tool element carrier in at least one advancing position. | 2022-08-18 |
20220257256 | CLAMP DEVICE USED IN COOPERATION WITH ENDOSCOPE, AND CLAMPING PORTION OF CLAMP DEVICE - Disclosed is a clamp device used in cooperation with an endoscope. A clamping portion of the clamp device comprises clamping pieces, a clamp tube, a clamping piece fixing seat and a connecting tube, wherein the clamping piece fixing seat is arranged in the clamp tube and can move forwards and backwards; the connecting tube is fixed at the rear end of the clamping piece fixing seat; the tails of the two clamping pieces are accommodated in the clamp tube, and the tails of the clamping pieces are movably connected to the front end of the clamping piece fixing seat by means of a deformation hole; stopping steps are arranged on an inner wall of the tail of the clamp tube. | 2022-08-18 |
20220257257 | IMPLANTABLE SPHINCTER ASSISTANCE DEVICE WITH DEFORMABLE ELEMENTS - A sphincter augmentation device includes a plurality of interlinked bodies and a pair of device ends configured to releasably couple together to secure the bodies in a loop formation sized to fit around an internal anatomical passageway of a patient. The device further includes a plurality of resilient members, with each resilient member extending between an adjacent pair of the bodies. The resilient members are configured to elastically deform to permit the device to transition between a radially contracted state and a radially expanded state. The resilient members bias the device toward the radially contracted state in which the device exerts an inwardly directed force on the anatomical passageway to selectively limit passage of fluids therethrough. The device further includes an expansion limiting member that extends between and is slidably received by an adjacent pair of the bodies, and is configured to limit radial expansion of the device. | 2022-08-18 |
20220257258 | FILAMENTARY DEVICES FOR TREATMENT OF VASCULAR DEFECTS - Devices and methods for treatment of a patient's vasculature are described. Embodiments may include a permeable implant such as a permeable shell or mesh having a radially constrained state configured for delivery within a catheter lumen, an expanded state, and a plurality of elongate filaments that are woven together. The permeable implant may include a stiffer proximal portion that is configured to sit at the neck of an aneurysm. The stiffer proximal portion may include additional mesh layers on either the inside or the outside of a first permeable shell. The distal portion of the device may be softer and deformable. | 2022-08-18 |
20220257259 | OCCLUSION DEVICE - An occlusion device includes a sealing disc, and a fixing frame connected to the sealing disc and located on one side of the sealing disc. The fixing frame includes a connecting portion connected to the sealing disc and at least one supporting body. The at least one supporting body radiates from the connecting portion and extends towards a proximal end to form a plurality of supporting sections. The supporting section is provided with at least one first restraint portion. The fixing frame is provided with at least one second restraint portion. The occlusion device further includes at least one restraint member. The restraint member is connected to the first and second restraint portion so a portion of the restraint member between the first and second restraint portion generates a restraint force that restrains movement of at least the supporting section. | 2022-08-18 |
