Publication number: 20120065675Abstract: Methods and apparatus are provided for temporarily occluding a body opening. A method in accordance with one or more embodiments of the invention includes introducing a tip of a catheter into the body opening, the tip including a central longitudinal axis; expelling a thermosensitive polymer from the tip of the catheter into a portion of the body opening, allowing the thermosensitive polymer to harden as it warms to body temperature to form a plug in the body lumen, and removing the plug.Type: ApplicationFiled: September 23, 2011Publication date: March 15, 2012Applicant: FOSSA MEDICAL, INC.Inventor: Gloria Ro Kolb

Patent number: 8062282Abstract: Methods and apparatus are provided for temporarily occluding a body lumen. A method in accordance with one or more embodiments of the invention includes introducing a tip of a catheter into the body lumen, the tip including a central longitudinal axis; expelling a thermosensitive polymer from the tip of the catheter into a portion of the body lumen, with at least a portion of the thermosensitive polymer being expelled from the tip in a direction generally radially outward from the central longitudinal axis to improve adherence of the thermosensitive polymer to a wall defining the body lumen; and at least partially withdrawing the tip from the body lumen and allowing the thermosensitive polymer to harden as it warms to body temperature to form a plug in the body lumen.Type: GrantFiled: February 9, 2007Date of Patent: November 22, 2011Assignee: Fossa Medical, Inc.Inventor: Gloria R. Kolb

Patent number: 7674283Abstract: An expandable, elongate flexible conduit is provided for placement in a tubular body structure. An exemplary conduit includes a plurality of flexible longitudinal members defining in an unexpanded state a lumen, the members being radially expandable at preselected intervals to define a longitudinally oriented array of open-sided cages separated by less-expanded tubular segments, at least one of the open-sided cages having a diameter varying along its length and each of the open-sided cages having a maximum diameter larger than a diameter of the less-expanded tubular segments.Type: GrantFiled: October 21, 2004Date of Patent: March 9, 2010Assignee: Fossa Medical, Inc.Inventors: Michael Mitchell, Gloria Ro, Aoy Tomita

Patent number: 7217250Abstract: A stent may include a flexible, elongate body having a curled proximal portion, a curled distal portion, and a main portion extending between the proximal and distal portions. The main and distal portions together may define a channel laterally open throughout at least a part of the channel's length and extending along the main and distal portions without extending along the proximal portion, whereby the channel's proximal end is disposed in the main portion. In addition, the proximal portion may be curled away from the channel.Type: GrantFiled: August 16, 2005Date of Patent: May 15, 2007Assignee: Fossa Medical, Inc.Inventor: Gloria Ro Kolb

Patent number: 7214229Abstract: The present disclosure is directed to embodiments of devices for capturing obstructions within passageways. The devices disclosed herein may include a flexible tubular body forming multiple flexible members arranged in a helical pattern. These flexible members may be expandable to form one or more cages when the tubular body is expanded to an increased diameter state. The cages may be generally centered around the longitudinal axis of the tubular body between the two ends of the body. Also disclosed herein are methods for capturing obstructions within passageways, methods for obtaining tissue samples from body passages, and methods for making devices for capturing obstructions within passageways.Type: GrantFiled: June 25, 2002Date of Patent: May 8, 2007Assignee: Fossa Medical, Inc.Inventors: Michael Mitchell, Mark Manasas, Gloria Ro Kolb

Publication number: 20050228481Abstract: Embodiments of medical devices are described, such as stents, for dilating passageways. A medical device can include a flexible body, having a proximal end, a distal end, and a longitudinal axis. The flexible body can further include a flexible elongate member that is defined by a longitudinally extending aperture in the body. The member can be radially expandable with respect to the longitudinal axis. The device can also define an eccentric lumen, at least a portion of the eccentric lumen being offset from the longitudinal axis.Type: ApplicationFiled: October 8, 2003Publication date: October 13, 2005Applicant: Fossa Medical, IncInventors: Mark Manasas, Gloria Kolb

Patent number: 6709465Abstract: A ureteral device is provided for facilitating stone passage through a ureter or duct. An exemplary ureteral device includes a flexible, elongate body that defines a plurality of cages along the body. In a contracted state the cages have a reduced diameter. When an activation force is applied, the cages transform to an expanded state, thereby defining a plurality of void spaces. The void spaces are configured to receive an obstruction, such as a stone. The ureteral device can then be induced to the contracted state to compress the obstruction within the elongate, flexible body and then be removed from the obstructed passage. The ureteral device can be configured to have different numbers of elongate flexible members that define the cages.Type: GrantFiled: January 5, 2001Date of Patent: March 23, 2004Assignee: Fossa Medical, Inc.Inventors: Michael Edward Mitchell, Gloria Miran Ro, Aoy Tomita
