Patent number: 9993235Abstract: Disclosed herein is a non-vascular fistula treatment system. The system may include a collapsible member, at least one tether, and a bioresorbable material. The collapsible member may be configured for positioning through a fistula tract and may comprise first and second disc members. The outer perimeter of the second disc member may be larger than the outer perimeter of the first disc member, and the first disc member may comprise a tether attachment structure. The at least one tether may be attached to the tether attachment structure. The bioresorbable material may be configured for placement in the fistula tract and may comprise a coupling structure configured to couple to the at least one tether. The second disc member may be configured to seal to a surface of a body lumen at a distal opening of the fistula tract and occlude the fistula tract at the distal opening.Type: GrantFiled: February 15, 2013Date of Patent: June 12, 2018Assignee: Curaseal Inc.Inventors: Akshay Mavani, Kenton Fong, Leif Erik Bansner, Nathan Christopher Maier, Dean Hu, Moshe Pinto, Harold Francis Carrison, Eliot Kim

Publication number: 20130158594Abstract: Disclosed herein are implantable fistula treatment devices and related methods. In some embodiments, an anorectal fistula treatment device may comprise a disc-shaped distal anchor comprising a concave side and a convex side, an outer edge region, an inner sealing region protruding from the concave side, and an attachment region configured for attachment to a connecting member. The inner sealing region may have a greater thickness than at least a portion of the attachment region and the outer edge region may be oriented at an acute angle to the inner sealing region. The distal anchor may have a tapered edge and the outer edge region and inner sealing region may be configured to form separate seals against tissue about a distal opening of an anorectal fistula.Type: ApplicationFiled: June 15, 2012Publication date: June 20, 2013Applicant: CuraSeal Inc.Inventors: Harold F. Carrison, Mark-Christopher O. Santos

Patent number: 8377094Abstract: Disclosed herein is an implantable fistula closure device. The device may include an expandable longitudinally segmented body including a proximal end and a distal end. The segmented body may further include a plurality of porous bodies and a connecting member operably joining together the plurality of porous bodies. The plurality of porous bodies includes a first porous body with a proximal end and a distal end and a second porous body with a proximal end and a distal end, and the connecting member operably connects the proximal end of the first porous body with the distal end of the second porous body.Type: GrantFiled: September 26, 2011Date of Patent: February 19, 2013Assignee: Curaseal Inc.Inventors: Akshay Mavani, Kenton Fong, Leif Erik Bansner, Nathan Christopher Maier, Dean Hu, Moshe Pinto, Harold Francis Carrison, Eliot Kim

Publication number: 20130006283Abstract: Disclosed herein are implantable fistula treatment devices and related methods. In some embodiments, a distal anchor for an implantable fistula treatment device may comprise a suture and a plurality of foldable members including at least a distal-most foldable member and a proximal-most foldable member. The distal-most foldable member may comprise a suture attachment structure. The distal-most foldable member may comprise a distal first average dimension substantially parallel to the longitudinal axis of the suture, a distal second average dimension orthogonal to the distal first average dimension, and a distal third average dimension orthogonal to the distal first and second average dimensions. The distal first average dimension may be no greater than 30% of the greater of the distal second and third average dimensions. The proximal-most foldable member may be configured to couple to a surface of a body lumen at a distal opening of a fistula.Type: ApplicationFiled: June 15, 2012Publication date: January 3, 2013Applicant: CuraSeal Inc.Inventors: Harold F. Carrison, Yolanda Pacho Huynh
