Patent number: 9504458Abstract: Described, in certain respects, are unique methods and systems for treating fistulae and other passageways and openings in the body. In some embodiments, treatment will be performed on fistulae that include a passage extending through a subcutaneous wall or wall-like structure. Illustratively, such a passage can extend through a subcutaneous tissue wall that includes, at a minimum, portions of an intestinal wall, and in this regard, such a wall can have a first side that is provided by the luminal side of the intestines and a second subcutaneous side that is provided, for example, by the abluminal side of the intestines and/or by other subcutaneous tissues adhered to this abluminal side. Some inventive products and methods involve sealing off the passage from both sides of the wall, for example, where a sealing element is placed on each side of the wall over an opening to the passage.Type: GrantFiled: January 16, 2013Date of Patent: November 29, 2016Assignee: Cook Biotech IncorporatedInventors: F. Joseph Obermiller, Kevin D. Parish, Mark Duncan, Derick C. Miller, P. Arun Mohan

Patent number: 9492149Abstract: Described are medical products, systems, and methods useful for treating fistulae, particularly enterocutaneous fistulae. Certain inventive products are configured to have portions residing in and around a primary fistula opening in a wall of the alimentary canal. One product includes a graft body which is configured to block at least the primary opening. The graft body includes a capping member connected to an elongate plug member. The capping member is configured to contact portions of the alimentary canal wall adjacent to the primary opening, with the elongate plug member extending into at least a portion of the fistula. A product of this sort may be particularly adapted to allow a portion of the capping member to be positioned alongside an exterior, lateral surface of the plug member, e.g., when placed in a delivery device lumen. Such a capping member may be hingedly or non-hingedly coupled to the elongate plug member.Type: GrantFiled: November 12, 2008Date of Patent: November 15, 2016Assignee: Cook Biotech IncorporatedInventors: F.

Patent number: 9456813Abstract: Described are devices, methods, and systems useful in the treatment of fistulae, and in certain embodiments those having openings extending into the alimentary canal, such as anorectal fistulae. Illustratively, an anorectal fistula can be treated by placing a volumetric construct within the primary opening of the fistula. In certain embodiments, the volumetric construct can include a rolled remodelable material processed to form a substantially unitary body. Advantageous such remodelable materials can include collagenous extracellular matrix materials, such as small intestine submucosa.Type: GrantFiled: April 2, 2012Date of Patent: October 4, 2016Assignee: Cook Biotech IncorporatedInventors: F. Joseph Obermiller, Michael C. Hiles, Matthew R. Graham

Patent number: 9456815Abstract: An implantable graft, which may be inserted into a fistula tract to occlude the primary opening of the fistula, is provided. To prevent unintentional displacement of the graft or extrusion of the graft from the fistula of a patient, the graft may be provided with a cap that extends laterally from at least one end of the body of the graft, where the cap may be integral with the body of the graft, attachable to at least one end of the body of the graft, and/or moveable along the body of the graft. The graft may also have a tail that extends from one end of the body of the graft to assist in placement of the graft in a fistula tract. The graft may be an integral unit made of a single material, such as a heterograft material, or may include distinct components made of the same or different materials. Methods for closing a fistula tract are also provided.Type: GrantFiled: August 21, 2014Date of Patent: October 4, 2016Assignees: COOK MEDICAL TECHNOLOGIES LLC, COOK BIOTECH INCORPORATEDInventors: David N. Armstrong, Brian L. Bates, Mark W. Bleyer, F. Joseph Obermiller, Umesh H. Patel

Publication number: 20160262737Abstract: Among other things, there are disclosed apparatuses and methods for medically sealing an opening in a vessel or wall. For example, in medical applications, a delivery tube is provided for insertion through a sheath into a vessel (e.g. a blood vessel). A dome-shaped seal fixed to a filament, an absorbent and/or compressible buffer, and a locking member are provided in the delivery tube. The delivery tube is configured so that it can be inserted into the vessel through a sheath. Tension is maintained on the filament to hold the seal against the tube or sheath. The sheath is pulled out, which pulls out the tube at the same time, leaving the seal over the opening in the vessel wall. The locking member compresses the buffer against the outside of the vessel and with the filament holds the seal in place against the inside of a vessel.Type: ApplicationFiled: March 7, 2016Publication date: September 15, 2016Inventors: Ram H. Paul, JR., Cleon Stanley, Brian L. Bates, F. Joseph Obermiller, Thomas A. Osborne, Sean D. Chambers

Patent number: 9271817Abstract: Tissue augmentation devices, as well as methods of manufacturing and using the same, are disclosed. In certain embodiments, a tissue augmentation device comprises an elongate tissue penetrating member and an amount of remodelable material, wherein at least a portion of the elongate member is cannulated, and at least a portion of the amount of material is received within at least a portion of the cannulated portion of the elongate member. The elongate tissue penetrating member may provide at least one deformation that is configured to constrict portions of the amount of remodelable material received within the elongate member. In alternate embodiments, a flexible covering over an implantable biomaterial provides protection and allows an easier delivery of the biomaterial to a tissue tract.Type: GrantFiled: May 2, 2008Date of Patent: March 1, 2016Assignee: Cook Biotech IncorporatedInventors: Ryan Dempsey, Jeffrey Miller, Steve Chen, Umesh H.

Publication number: 20150157332Abstract: Certain aspects of the present invention provide devices for occluding vascular vessels. In some preferred forms, these devices are able to move from a first condition to a less compact, second condition in a vascular vessel so as to fully or partially prevent fluid from passing through the vessel. One such device includes a frame and a flexible sheet material. The device also includes an occluding material that is located in an interior region of the frame. The flexible sheet material and frame are associated with one another such that when the device is in the second condition in the vascular vessel, the sheet material is positioned in the vessel lumen so as to block fluid flow through the lumen.Type: ApplicationFiled: February 17, 2015Publication date: June 11, 2015Inventors: F.

Patent number: 8915941Abstract: Described are methods and systems for treating fistulae and other passageways and openings in the body. In certain aspects, an anchored suture is provided that extends from at or near a first fistula opening and through a fistula tract toward a second fistula opening. Various modes of anchoring may be used in this regard including, in some modes, having the suture extend from a deployed anchoring member positioned in and/or around the first opening. The anchored suture, which has a more slender cross sectional dimension relative to the fistula tract through which it extends, is capable of receiving an optional fill substance therealong in the tract. A fill substance can be or include a variety of biodegradable and/or non-biodegradable objects and materials including flowable and non-flowable materials.Type: GrantFiled: June 14, 2012Date of Patent: December 23, 2014Assignees: Cook Medical Technologies LLC, Cook Biotech IncorporatedInventors: F.
