Abstract: The present technology relates to endoscope devices and methods of use for said endoscope devices. In one embodiment, the device comprises a semicircular aspiration channel with a blocking bar disposed at an outlet of the semicircular aspiration channel to prevent clogging of said channel. The endoscope devices of the present invention may further comprise a plurality of working channels, an image sensor, and a light source. In addition, for work within the ureter, a force sensor is incorporated to ensure safe passage of the largest flexible ureteroscope.

Abstract: Various embodiments herein comprise a handheld load sensing device. In one embodiment, the device comprises a force sensor (e.g., a mechanical spring or an electromechanical load cell) adapted to receive a force, an input/output interface, and an adjustable attachment mechanism adapted to reversibly attach a surgical device. In another embodiment, the force sensor detects the amount of force applied during the deployment of the surgical device in a patient and outputs a force value representative thereof via the input/output interface. Also provided herein are methods of making and using load sensing devices.

Abstract: A medical urology device for drug delivery to the lining and deeper tissues of the ureter and kidney. The present invention features an electromotive drug administration (EMDA) catheter device for deploying a fluid to deep tissues of a patient. The device includes a catheter body with fenestrations along its distal length. The device may further comprise a multiport component for allowing access to the catheter body. The device may further comprise a conductive wire removably disposed through the multiport component within the catheter body. Fluid may be directed through the multiport component and the plurality of fenestrations to the body structure of the patient. Electrical stimulation directed through the conductive wire enhances the penetration of medications with the same polarity to electrical stimulation into a body structure of the patient to allow the fluid to penetrate deep tissues.
