Patent number: 8721713Abstract: A system for percutaneously inserting a prosthesis containing a biological replacement for a defective valve into an implantation site through a body lumen. The system contains a balloon catheter upon which a collapsable stent containing a venous valvular replacement is mounted. A protective shield is slidably mounted upon the catheter that is movable between a closed position over the balloon and an open position wherein the balloon can be inflated to expand the stent. A central lumen runs through the catheter that is formed of stainless steel. The central lumen provides a one to one torque ratio between the proximal end of the catheter and the distal end to enhance the steerability of the catheter. The vein of the replacement is reduced in thickness between 50% and 90% of its original size thereby considerably reducing the size of the replacement package when the stem is collapsed upon the balloon of the catheter.Type: GrantFiled: April 23, 2002Date of Patent: May 13, 2014Assignee: Medtronic, Inc.Inventors: Allen J.

Patent number: 8709095Abstract: A structure made of collagen for improving promotion of nerve tissue regeneration, curing and regeneration of a defective part of a soft biological tissue and so on without using laminin or nerve growth factor (NGF), and a member for tissue regeneration including the same. The structure made of collagen has a thin film multilocular formation and is therefore a structure different from a colloid form, a gel form, and a fiber form. When the new structure made of collagen is used as a member for tissue regeneration, surprisingly, promotion of regeneration, shortening of a treatment period, functional recovery, or the like of bodily tissue such as nerve tissue, subdermal tissue, submucosal tissue, membranous tissue, fat tissue, muscle tissue, skin tissue, and gingival tissue can be improved. When the structure is used in a patient having neuropathic pain, the member has an effect on the disappearance of the pain.Type: GrantFiled: February 4, 2013Date of Patent: April 29, 2014Assignee: Kyoto UniversityInventors: Tatsuo Nakamura, Yuji Inada, Keiji Shigeno
