Publication number: 20230089310Abstract: Devices and methods are disclosed for determining prostatic urethral length. A balloon catheter subassembly is in fluid communication between an inner cavity of a syringe body and an expandable balloon is positioned at a distal end of the balloon catheter subassembly. An adapter secured to the syringe body having a syringe plunger includes a lock that engages the syringe plunger at a predefined position with respect to the syringe body corresponding to a desired inflation state of the expandable balloon. Prostatic urethral length can then be determined using markings indicating distance from the expandable balloon.Type: ApplicationFiled: September 20, 2022Publication date: March 23, 2023Inventors: Chun-Chia Juan, Yu-Chen Lin, Yu-Shih Weng, Yue-Teh Jang

Publication number: 20220387165Abstract: Devices and methods are disclosed for determining prostatic urethral length. A measuring device having an elongated shaft member with associated markings may be advanced through a working channel of the cystoscope so that a positioning aid disposed on the elongated shaft member is located at a bladder neck of the patient. A first position of the elongated shaft member is determined using the markings. The elongated shaft member is then withdrawn to a second position at which the positioning aid is located at the patient's verumontanum. The prostatic urethral length is determined based at least in part on relative translational movement of the elongated shaft member between the first position and the second position using the markings.Type: ApplicationFiled: June 3, 2022Publication date: December 8, 2022Applicant: Prodeon Medical CorporationInventors: Yue-Teh Jang, Yu-Shih Weng, Chun-Chia Juan, De-Yu Chu

Patent number: 11076849Abstract: An elongated deployment shaft carrying a needle deployment assembly with needles carrying sutures and a stabilizer. A catcher tube over the shaft having a catcher assembly at a distal end may retain a portion of the needles when passed through the tissue into engagement with catcher assembly. The catcher and needle deployment assemblies are configured to asynchronously engage the plurality of needles when moved distally beyond the catcher assembly. A sheath over the catcher tube may sandwich the tissue against the stabilizer when expanded. A first actuator may move catcher tube distally to decrease distance between proximal and distal ends of the stabilizer expand it and may move the sheath distally to sandwich the tissue. A second actuator may deflect the needles outward to move proximally through the tissue and engage the catcher and return a portion of each not retained by the catcher to a distal position.Type: GrantFiled: January 31, 2019Date of Patent: August 3, 2021Assignee: TERUMO MEDICAL CORPORATIONInventors: Chun-Chia Juan, Yu-Shih Weng
