Patent number: 6482213Abstract: An apparatus including a serrated cone for interoperation with a loader. The cone includes a conical ramp portion, a cylindrical base portion, and at least one fin slot. The ramp portion defines a cone ramp surface and has a large diameter end and a small diameter end. The base portion extends longitudinally from the large diameter end of the ramp portion and has a radially outer surface. The fin slot is defined in the cone ramp surface and the radially outer surface of the base portion. The loader includes a plunger and a glider. The plunger has a fin for urging the elastomeric band along the ramp portion. The glider has a surface for engaging the elastomeric band and urging the elastomeric band over the base portion. The glider is moveably related to the plunger.Type: GrantFiled: May 30, 2000Date of Patent: November 19, 2002Inventor: Erol D. Riza

Patent number: 6464708Abstract: A fluid circuit connects a pressure applying portion (17, 20) and a distal device (1) to charge fluid into the distal device (1). The fluid circuit includes a controller (10, 11) to control the movement of ligating rings (13). The controller (10, 11) senses a pressure drop in the distal device (1) when one or a plural number of the ligating rings (13) are separated from the distal device (1). The movement of the ligating rings (13) is stopped in accordance with the pressure drop so that at least two or more of the ligating rings can be separated at a time. Accordingly, ligation of esophageal varices and internal hemorrhoids can be performed successively.Type: GrantFiled: June 18, 2000Date of Patent: October 15, 2002Assignee: Sumitomo Bakelite Co., Ltd.Inventors: Masato Higuma, Haruhiko Masuda

Patent number: 6464685Abstract: An endoscopic ligation kit including an inner cylinder, an outer cylinder having at least two step portions of diminishing outer radii formed on the outer periphery of its distal end portion, and a slide cylinder provided between the inner cylinder and the outer cylinder. The outer cylinder has a notch extending from its distal end portion to its maximum outer diameter portion. The slide cylinder has at its distal end portion a projection which conforms in size to the notch, and has steps and the projection is fitted in the notch. O-rings are mounted respectively on the outer periphery of the distal end portion of the inner cylinder and the step portions of the outer cylinder.Type: GrantFiled: September 7, 2000Date of Patent: October 15, 2002Assignee: Sumitomo Bakelite Company LTDInventors: Zenetsu Suzuki, Haruhiko Masuda

Patent number: 6409737Abstract: An improved elastic band for ligating tissue within a living body comprises a central opening defining an axis. A first curved edge is formed between a first surface extending substantially parallel to the axis and a second surface extending substantially perpendicular to the axis. A method of ligating tissue within a living body using such a ligating band comprises the steps of positioning the elastic band, which has been stretched to increase the size of a central opening extending therethrough, adjacent to a portion of tissue to be ligated. The tissue to be ligated is then drawn through the central opening of the elastic band and the elastic band is released so that the size of the central opening decreases to grip the tissue received therein.Type: GrantFiled: October 8, 1999Date of Patent: June 25, 2002Assignee: Scimed Life Systems, Inc.Inventors: Richard C. Fortier, Susan M. Ostrowski

Patent number: 6325809Abstract: The present invention is directed to a plug for insertion into a distal end of a ligating unit including an aspiration cylinder coupled to a distal end of an endoscope. The plug comprises a mounting portion sized to fit within an opening formed in a distal end of the aspiration cylinder and a protruding portion extending away from the mounting portion to project distally from the aspiration cylinder when the insertion plug is mounted in the aspiration cylinder.Type: GrantFiled: December 20, 1999Date of Patent: December 4, 2001Assignee: Boston Scientific CorporationInventor: Gayjoy M. Bryars

Patent number: 6280452Abstract: A ligating band dispenser includes a cylindrical inner sleeve and at least a partially encompassing balloon, where the inner sleeve supports one or more expanded ligating bands external to the balloon. This ligating band dispenser allows the introduction of a pressurized fluid between the inner sleeve and the balloon, proximal to a distal-most, stored ligating band, to effect the distal displacement and dispensing of one or more stored ligating bands.Type: GrantFiled: June 22, 1998Date of Patent: August 28, 2001Assignee: Ensurg, Inc.Inventor: Eric L. Mears

Patent number: 6152936Abstract: A surgical loop delivery device is disclosed in parent disclosures Ser. No. 09/071,811 and U.S. Pat. No. 5,766,217. This device is improved to permit tissue targets larger than the device to be ligated while also maintaining a clear sight path between the surgeon and the target. The surgical loop is also stable during the procedure.Type: GrantFiled: February 2, 1999Date of Patent: November 28, 2000Assignee: ESD Medical, LLCInventors: William J. Christy, James R.

Patent number: 6149659Abstract: An endoscopic ligating apparatus is provided that can be used percutaneuously to dispense multiple ligating bands or rings about several lesions. In one embodiment, a barrel supporting a plurality of bands stretched around its circumference is removably engaged to the insertion end of an endoscope. A trip wire extends through a working channel of the endoscope and includes a plurality of strands extending from the distal end of the barrel and wrapped around the end of the barrel. The ligating bands are situated over the strands, while the strands are provided with beads disposed adjacent the bands. As tension is applied to the trip wire by way of an activating mechanism, the strands retract within the barrel so that the beads draw the ligating bands successively to the end of the barrel. In one embodiment, the activating mechanism includes a mounting component that stably mounts the mechanism to a variety of endoscopes.Type: GrantFiled: September 21, 1998Date of Patent: November 21, 2000Assignee: DabeGran Technologies, Inc.Inventor: Munir Ahmed

Patent number: 6136009Abstract: A ligating band dispenser has a first sleeve, to store one or more ligating bands, and a second member, which at least partially extends about and is movable relative to the first sleeve. The second sleeve is capable of engaging and moving a distal-most ligating band positioned on the first sleeve from an initial storage position to a dispensing position, irrespective of other ligating bands which may be stored thereon.Type: GrantFiled: May 6, 1998Date of Patent: October 24, 2000Assignee: Ensurg, Inc.Inventor: Eric L.

Patent number: 6099535Abstract: A hydraulically multiple ligating band dispenser comprising a body whose distal portion is adapted to support the elastic ligating bands. A tissue contacting surface is disposed surrounding and spaced from the distal portion so as to define a chamber. A seal slidably mounted on the distal potion is shaped to seal the chamber, to which a proximally situated fluid inlet is coupled. By these means pressurized fluid applied to the fluid inlet causes the seal to slide in a distal direction along the distal portion in order to urge the ligating bands distally and to dispense them serially.Type: GrantFiled: March 19, 1999Date of Patent: August 8, 2000Assignee: C.R. Bard, Inc.Inventors: Ronald Lamport, Gregory Stiegmann, Frank Van Patterson
