Patent number: 12193753Abstract: A system is provided for stimulating renal nerves. The system includes an interstitial device to provide stimulation and denervation of the renal nerves from outside the renal artery. The interstitial device extends through non-vascular tissue and into a periarterial space. The system also includes a control unit in communication with the interstitial device, configured to: obtain, from a sensor, first information pertaining to a blood pressure or heart rate; stimulate, using one or more electrodes of the interstitial device, renal sympathetic nerves associated with the renal artery; and obtain, from the sensor, second information pertaining to the blood pressure or heart rate of the subject. Based on a difference between the first information and the second information, the control unit determines whether the subject is suitable for a sympathetic denervation procedure and causes the interstitial device to perform the sympathetic denervation procedure if the subject is suitable.Type: GrantFiled: January 9, 2023Date of Patent: January 14, 2025Assignee: KONINKLIJKE PHILIPS N.V.Inventor: Steffen Weiss

Patent number: 12121287Abstract: An improved drive shaft for controlling an end effector of surgical instrument having advantages over the prior art, specifically, the drive shaft includes two separate elongate elements, each including a flange at its proximal end for restricting the lateral movement of the drive shaft when installed within an outer shaft of the instrument. The dimensions of the flanges are such that they fit within the outer shaft with minimal clearance. This allows the drive shaft to be moved longitudinally within the outer shaft to actuate an end effector whilst minimizing any lateral movement. This consequently prevents the end effector from tilting as it is actuated. The drive members are arranged so that the flanges extend in opposite directions perpendicular to the length of the drive shaft. This helps to improve ease of assembly and provides space within the outer shaft for features such as connection wires and the like.Type: GrantFiled: April 26, 2021Date of Patent: October 22, 2024Assignee: GYRUS ACMI, INCInventors: Daniel Thomas, Marno Nagtegaal, Nafiseh Ahanchian

Patent number: 12114911Abstract: A medical system for ablating a tissue site by electroporation with real-time pulse monitoring during an electroporation treatment procedure is provided. The treatment control module monitors applied pulses and detect an abnormal condition that indicates either an ineffective electroporation of the tissue or an imminent excessive current such as a spark event that may exceed the capacity of the pulse generator. Rather than terminating the procedure entirety, the treatment control module temporarily pauses the procedure to allow the user to adjust the pulse parameters so as to complete the procedure without starting the procedure over again.Type: GrantFiled: August 27, 2015Date of Patent: October 15, 2024Assignee: ANGIODYNAMICS, INC.Inventor: Robert Neal, II
