Abstract: A device for treating trigger thumb or trigger finger may include a handle, an introducer shaft extending from the handle, a blade shaft slidably disposed on the handle and the introducer shaft, a blade at or near a distal end of the blade shaft, a slider on the handle, attached to a proximal end of the blade shaft, for sliding the blade shaft and the blade distally and proximally along the introducer shaft, and a neurovascular guard slidably coupled with the handle and disposed over at least part of the blade shaft. The neurovascular guard may be made of a material that allows passage of ultrasound waves, such as Ultem, PEEK, PPS, or other polymers.

Abstract: The invention provides a tissue cutting device comprising a handle, a first blade, and a second blade. The second blade is coupled to the handle. The second blade is rotatable relative to the first blade such that the second blade is configured to rotate between a first position and a second position. The second blade is in a same plane as the first blade when the second blade is in the first position. The second blade is rotated into a different plane from the first blade when the second blade is rotated from the first position toward the second position.

Abstract: A device for treating de Quervain's tenosynovitis may include a handle, an introducer shaft extending from the handle, and a blade that includes a blade shaft extending along a top surface of the introducer shaft and onto the handle and a blade cutting edge that faces toward the handle. The device may further include a blade slider attached to a proximal portion of the blade shaft, a blade pivot attached to at least one of the proximal portion of the blade shaft or the blade slider, an upper deck along which the blade slider slides in an upper horizontal orientation, and a lower deck along which the blade slider slides in a lower horizontal orientation. The blade pivot is configured to allow the blade slider to rotate in a plane that is perpendicular to a plane of the introducer shaft.

Abstract: Some embodiments provide a soft tissue device, such as a transverse carpal ligament cutting device having one or more balloons that are deflated when the device is in an inactive position and are inflated when the device is in an active position. Other embodiments provide a soft tissue cutting method, such as a method of cutting a transverse carpal ligament that uses a soft tissue cutting device.

Abstract: The presently disclosed subject matter relates generally to a device for cutting soft tissue, such as transverse carpal ligaments and annular ligaments of the finger, and methods of using the soft tissue cutting device. A soft tissue cutting device includes an inner tubular member extending between a distal end and a proximal end of the inner tube, an outer tubular member disposed over at least a portion of the inner tubular member and movable between an initial position and an extended position, an outer tubular member movement controller that controls movement of the outer tubular member between the initial position and the extended position, and an attachment mechanism for removably coupling the proximal end of the inner tubular member to a dispensing member. A distal end of the outer tubular member includes a cutting member.

Abstract: Methods of using a soft tissue cutting device are disclosed. The methods include providing the soft tissue cutting device, positioning the soft tissue cutting device in a priming slot of a tray configured for receiving and holding the soft tissue cutting device, attaching a priming syringe to the soft tissue cutting device, priming a balloon disposed on a distal end of the soft tissue cutting device by equalizing a first pressure inside the balloon to a second pressure inside the priming syringe, removing the soft tissue cutting device from the priming slot, and positioning the distal end of the soft tissue cutting device on a safety slot included in the tray to determine whether the tissue cutting device has been properly primed.

Abstract: A method of cutting soft tissue in a hand to treat trigger finger involves advancing an introducer shaft into the hand to position a distal end of the introducer shaft beyond a pulley in a finger of the hand, advancing a blade along a guiding channel on an upper surface of the introducer shaft, to position a distal end of the blade at or near the distal end of the introducer shaft, and rotating a cutting surface of the blade to an orientation at or near perpendicular relative to the upper surface of the introducer shaft. The method further involves retracting the blade along the introducer shaft to cut the pulley and removing the introducer shaft and the blade from the hand.

Abstract: Device, systems, and method for cutting body tissue may include a handle, a blade, a shaft, and an expander. The handle may include a slider and a lever in communication with the slider. The blade may be coupled with the slider. The shaft may extend distally from the handle and the shaft may define a guideway along which the blade is configured to travel. The expander may be in communication with the lever and extend along the shaft. Actuation of the lever may adjust the expander to an expanded position and unlock the slider to allow actuation of the slider and longitudinal movement of the blade along the guideway. The expander may be or may include one or more balloons.
