Patent number: 11925376Abstract: Apparatus and methods are described for treatment of a urethra that is constricted due to benign prostatic hyperplasia (BPH). A positioning device is used to determine a location of the area of the urethra that is constricted and is to be treated. An execution device includes a dilation balloon, a cutter, an implant carrier, and an implant, the implant and the implant carrier both being disposed outside the outer surface of the dilation balloon. The urethra is dilated by expanding the dilation balloon, and a cut is formed in the inner surface of the urethra using the cutter. The implant is released into the cut within the inner surface of the urethra subsequent to the cutter forming the cut in the inner surface of the urethra, to thereby maintain the urethra in a dilated state. Other embodiments are also described.Type: GrantFiled: November 23, 2021Date of Patent: March 12, 2024Assignee: ProArc Medical Ltd.Inventors: Shai Golan, Raz Bar-On, Boaz Harari, Yair Feld

Publication number: 20220079577Abstract: Devices and methods of endolumenal formation of gastric sleeves are described. In some embodiments, a bougie capsule section comprises one or more mechanisms to allow flexing that induces a bend through a suction clamping domain that grabs, positions, and holds body lumen tissue (e.g., gastric wall tissue). In some embodiments, a needle drive is configured to allow longitudinal movement of a helical needle through a suturing space defined by the suction clamping domain, optionally while the suction clamping domain is bent. In some embodiments, the suction clamping domain can insert to the stomach in a collapsed configuration, then expanded once in the stomach. Potentially, this allows grabbing and positioning larger and/or deeper folds of tissue for suturing.Type: ApplicationFiled: January 9, 2020Publication date: March 17, 2022Applicant: Nitinotes Ltd.Inventors: Raz BAR-ON, Gilad HEFTMAN, Itshak COHEN, Eli SHAPIRA, Marina DROR

Publication number: 20160000455Abstract: A system and method for treating a constricted bodily lumen, for example, a urethra constricted due to BPH. The method includes a planning stage, during which an area requiring treatment is visually identified, and an execution stage during which the lumen is expanded, a cut is formed in the inner surface of the tissue defining the lumen, and an implant is deployed in the cut. The implant can be an open C-shaped ring, and can be formed of a biodegradable material, or can be removed at a selected time after implantation. The system is formed of a planning device anchorable in the lumen and constructed to facilitate location of an area to be treated, and execution device constructed to deliver an implant, to expand the lumen, to form a cut in the inner surface of tissue defining the lumen, and to release the implant for deployment into the cut.Type: ApplicationFiled: March 13, 2014Publication date: January 7, 2016Inventors: Shai GOLAN, Raz BAR-ON, Boaz HARARI, Yair FELD

Publication number: 20150246210Abstract: A delivery system for a self-expandable prosthesis includes a catheter having a distal portion and a proximal portion, a balloon portion positioned on the distal portion, and a self expanding medical device positioned about the balloon portion. The medical device has a compressed state and an expanded state. A sheath couples the medical device in its compressed state about the balloon portion and has only a single opening in a wall of the sheath. When the balloon is expanded, the sheath is configured to (i) first rupture at the single opening, thereby allowing the medical device to self-expand and engage an inner wall of a vessel, and (ii) controllably continue the rupturing from the single opening to the proximal end of sheath, thereby allowing the medical device to expand to its expanded state and a portion of the medical device to engage an inner wall of the vessel.Type: ApplicationFiled: March 10, 2015Publication date: September 3, 2015Applicant: CAPPELLA, INC.Inventors: Menashe YACOBY, Ascher SHMULEWITZ, Raz BAR-ON, Gil NAOR, Damian KELLY, Michael GILMORE, Mark STECKEL

Publication number: 20090299486Abstract: Gastrointestinal prosthesis for restraining the rate of the gastric digestion consists of a compressible proximal member connected by a string to a distal member, to be introduced into the intestine. The proximal member has an internal space, which is opened to the gastric lumen and may include passageways for the gastric content as well as open grooves or niches disposed on its external wall. The volume of a proximal member compressed by the gastric wall cannot get smaller than a lower threshold. Anchoring the gastrointestinal prosthesis at its desired location is accomplished by means of the proximal member the geometrical shape of which conforms the geometrical shape of a portion of the gastric lumen; as well as by means of the geometrical shape of the distal member which conforms the geometrical shape of a segment of the duodenum and/or a segment of the intestine.Type: ApplicationFiled: June 28, 2007Publication date: December 3, 2009Applicant: Slimedics Ltd.Inventors: Shaul Shohat, Raz Bar-On

Publication number: 20070043422Abstract: A delivery system for delivering a stent to a bifurcation in a vessel. The delivery system includes two guidewire lumens for directed the stent through the anatomy to the bifurcation. A main branch guidewire lumen has entry and exit ports that are positioned in order to limit how far the delivery system will be allowed into a side branch vessel. The orientation of the main branch guidewire lumen causes the delivery system to bind on the main branch guidewire as the system is positioned in the side branch. The location of the main branch guidewire lumen openings will physically limit the distance into the side branch that the stent will be placed.Type: ApplicationFiled: August 18, 2006Publication date: February 22, 2007Applicant: Cappella, Inc.Inventors: Ascher Shmulewitz, Menashe Yacoby, Gil Noar, Raz Bar-On
