A recently granted patent (Publication Number: US11925380B2) discloses a tissue slitting device designed for removing objects implanted in a patient. The device comprises a shaft with a cutting edge at the distal end that pivots on a pin following an actuation guide track. The support element of the device has a tapered outer surface and a lumen in communication with the shaft's inner lumen. The cutting edge pivots away from the longitudinal axis of the shaft as the pin travels through a non-linear portion of the guide track, aiding in the removal process.

Furthermore, the tissue slitting device includes features such as a slitting orientation control feature to prevent rotation into a vessel wall, an actuation element connected to an end support device lock for clamping onto the implanted object, and a collet arrangement in the support element to reduce the lumen diameter. The device's cutting edge is designed to pivot away from the implanted object with a lifting motion, creating tension on tissue fibers around the object. These innovative features aim to enhance the efficiency and safety of removing implanted objects in patients, showcasing advancements in medical device technology for surgical procedures.
