  • Patent number: 11617429
    Abstract: A scraping device has a scissor-like construction with two blades. Each blade can extend in a same plane as handle of the device. One of the blades is more dull than the other, the dull blade adapted to abut a part of the human body without causing any permanent physical change thereto, and the other being sharper than the dull blade which is designed to cut or remove part of the body. In some embodiments, one or both blades are rotatable in a plane which is normal to the direction of rotation of the handles relative to each other. In other embodiments, the blades are fixed at an angle relative to the handles and/or direction of movement of the handles. The dull blade may be inline with the handles while the sharp blade and/or cutting edge of the sharp blade is out of line therewith.

  • Patent number: 11596428
    Abstract: A surgical instrument is provided having an actuator mechanism with an integrated extension element. The surgical instrument comprises a handle assembly, an elongate shaft, and an end effector. The end effector comprises a jaw assembly having atraumatic pads to reduce force on grasped tissue. An actuator is movable within the elongate shaft to actuate jaws of the jaw assembly responsive to a movable handle of the handle assembly. The actuator can have an integrated extension element that allows the actuator to translate within the elongate shaft upon application of a relatively low force and translate and extend upon application of a relatively higher force to the actuator to limit the force applied by the jaw assembly. The actuator also utilizes forces stored with the integrated extension element to provide a dynamic amount of force used to grasp the tissue when the tissue volume decreases while in the jaws.

  • Patent number: 11426187
    Abstract: The forceps instrument includes a central pull-push member formed by transmission and actuating elements. The central push-pull member opens and closes the branches, and also acts as a tissue abutment that is variable based on the degree of closure of the branches. The variable tissue abutment may be configured as a slider element and is adjustable proportionally to the opening angle of the branches. When grasped, the vessels are brought proximally. The tissue abutment acts as a spacer between the hinge region and the grasped material. While the branches are being closed, the vessel is held stationary and compressed. During compression, expansion of the vessel occurs axially in distal and proximal directions. Due to the receding of the variable tissue abutment during the closing operation, room is created for the grasped material to escape. Tissue accumulations can thus be restricted and overstressing of the tissue can be counteracted.

  • Patent number: 10667804
    Abstract: Procedures may be performed on the heart after the installation of a mitral valve fixation device. In order to prepare the heart for such procedures, the fixation device may be removed or disabled in minimally invasive ways (e.g., through an endovascular procedure), without requiring open access to the heart. The fixation device may be partitioned so that one portion may remain attached to each leaflet of the mitral valve. In another example, the leaflets may be cut along the edges of the distal element(s) of the fixation device, so as to cut the fixation device from the leaflet(s). Systems and devices for performing such procedures endovascularly are disclosed. Fixation devices with improved access to a release harness are also disclosed.

  • Patent number: 10660506
    Abstract: Embodiments of the present disclosure are directed to apparatuses, devices, and methods for locks for endoscopic accessories. In one implementation, an adjustable lock for an endoscopic accessory includes a body slidably mounted upon a rail of the endoscopic accessory, and an arm extending about a portion of the body. The arm may be connected to the body and pivotable relative to the body between a closed position and an open position. In the closed position, teeth on an inner surface of the arm may engage a toothed rack on the rail such that the adjustable lock is secured to the rail. In the open position, the teeth on the inner surface of the arm may be clear of the toothed rack such that the lock may slide relative to the rail.

  • Patent number: 10639056
    Abstract: A differential dissecting instrument for differentially dissecting complex tissue is disclosed. The differential dissecting instrument comprises a handle and an elongate member having a first end and a second end, wherein the first end is connected to the handle. The differential dissecting instrument comprises a differential dissecting member configured to be rotatably attached to the second end and further comprises at least one tissue engaging surface. The differential dissecting instrument comprises a mechanism configured to mechanically rotate the differential dissecting member around an axis of rotation, thereby causing the at least one tissue engaging surface to move in at least one direction against the complex tissue. The at least one tissue engaging surface is configured to selectively engage the complex tissue such that the at least one tissue engaging surface disrupts at least one soft tissue in the complex tissue, but does not disrupt firm tissue in the complex tissue.

  • Patent number: 10603097
    Abstract: A treatment energy application structure includes a flexible substrate having an electric resistance pattern and a lead wire connection portion. A heat transfer plate faces the flexible substrate and transfers heat to the body tissue. An insulating adhesive sheet is interposed between the flexible substrate and the heat transfer plate. The insulating adhesive sheet comprises a first area to cover an entire surface of the electric resistance pattern and the heat transfer plate and a second area protruding from the heat transfer plate to cover a part of the lead wire connection portion. The heat transfer plate has a chamfered corner facing the insulating adhesive sheet. An adhesive may adhere the second area to at least one of the heat transfer plate and the substrate. The insulating adhesive sheet may adhere the substrate to both the heat transfer plate and the bridge portion of a cover.
