Publication number: 20110257677Abstract: A removable blood clot filter includes a number of locator members and anchor members disposed radially and extending angularly downward from a hub. The locator members include a number of linear portions having distinct axes configured to place a tip portion approximately parallel to the walls of a blood vessel when implanted and to apply sufficient force to the vessel walls to position the filter near the vessel centerline. The anchor members each include a hook configured to penetrate the vessel wall to prevent longitudinal movement due to blood flow. The hooks may have a cross section sized to allow for a larger radius of curvature under strain so that the filter can be removed without damaging the vessel wall.Type: ApplicationFiled: June 27, 2011Publication date: October 20, 2011Applicant: C.

Patent number: 7909886Abstract: This invention is directed to prosthesis, which, when implanted into a mammalian patient, serves as a functioning replacement for a body part, or tissue structure, and will undergo controlled biodegradation occurring concomitantly with bioremodeling by the patient's living cells. The prosthesis is treated so that it is rendered non-antigenic so as not to elicit a significant humoral immune response. The prosthesis of this invention, in its various embodiments, thus has dual properties. First, it functions as a substitute body part, and second, it functions as bioremodeling template for the ingrowth of host cells.Type: GrantFiled: March 24, 2006Date of Patent: March 22, 2011Assignee: Organogenesis, Inc.Inventors: Robert M. Carr, Jr., Kimberlie D. Condon, Paul L. Termin, Janet Hardin Young

Publication number: 20110034952Abstract: A filter delivery device for implanting a vessel filter within a blood vessel of a patient's body. The filter delivery device includes a mechanism for preventing hooks and/or legs on a vessel filter from entangling with each other while the vessel filter is loaded within the delivery device. In one variation, the filter delivery device includes a delivery catheter with grooves at the distal end lumen opening. When a vessel filter with radially expanding legs is compressed and inserted into the distal end of the delivery catheter, the hooks on the distal end of the legs are received and separated by the corresponding grooves on the delivery catheter. In another variation, a pusher rod, with a receptacle for receiving the hooks, is positioned within a delivery catheter to prevent the entanglement of the hooks and/or legs of a filter loaded within the delivery catheter.Type: ApplicationFiled: September 13, 2010Publication date: February 10, 2011Applicant: C.R. BARD, INC.Inventors: Alexander W. TESSMER, David G. SPILKA, David W. RAUCH, Andrzej J. CHANDUSZKO, Robert M. CARR, JR.

Patent number: 6893653Abstract: The invention is directed to collagenous tissues which have been treated to remove non-collagenous components such as cells, cellular debris, and other extracellular matrix components, such as proteoglycans and glycosaminoglycans, normally found in native tissues. Treatment of the tissue with alkali, chelating agents, acids and salts removes non-collagenous components from the collagenous tissue matrix while controlling the amount of swelling and dissolution so that the resultant collagen matrix retains its structural organization, integrity and bioremodelable properties. The process circumvents the need to use detergents and enzymes which detrimentally affect the cell compatibility, strength and bioremodelability of the collagen matrix. The collagenous tissue matrix is used for implantation, repair, or use in a mammalian host.Type: GrantFiled: July 8, 2003Date of Patent: May 17, 2005Assignee: Organogenesis Inc.Inventors: Ginger A. Abraham, Robert M. Carr, Jr., Paul D. Kemp, Ryan D. Mercer, Linda Baker
