Patent number: 6080174Abstract: An apparatus and method for forming and enlarging percutaneous penetrations comprises an elongate dilation member which receives an elongate expansion member in an axial lumen thereof. The dilation tube includes a tubular braid which usually comprises a mesh of non-elastic filaments which are radially expandable from a small diameter configuration to a large diameter configuration and which is optionally covered by a removable sheath. The dilation tube is percutaneously introduced to a target site within a patient's body, usually within the abdomen in a laparoscopic procedure. The sheath (if present) is then removed, and the tubular braid thereafter radially expanded by axial insertion of the expansion member through its lumen. The tubular braid is anchored by axial shortening of the mesh and remains in place to permit subsequent exchange of dilation members to provide for different diameter access lumens.Type: GrantFiled: April 19, 1995Date of Patent: June 27, 2000Assignee: Innerdyne, Inc.Inventors: William R.

Patent number: 6080177Abstract: A luminal stent is a tubular body formed by knitting a sole yarn of a bioresorbable polymer fiber, such as fiber of polylactic acid, polyglycol acid or a polylactic acid--polyglycol acid copolymer. When introduced into and attached to the inside of the vessel by a catheter fitted with a balloon, the tubular member may retain its shape for several weeks to several months after attachment and subsequently disappears by being absorbed into the living tissue. In this manner, the luminal stent is not left as a foreign matter semi-permanently in the living body without producing inflammation or hypertrophy in the vessel. There is also provided a method for attaching the luminal stent in the vessel.Type: GrantFiled: April 28, 1998Date of Patent: June 27, 2000Inventors: Keiji Igaki, Hideo Tamai

Patent number: RE36764Abstract: A device for removing obstructions from vessels or small openings in the body, comprising a rotatable ablator tip which is guided to the obstruction in a reduced diameter configuration, expanded and rotated to remove the obstruction, and contracted to remove the device from the body. The variably expandable abrasive tip coil in one embodiment of the invention is actuated by a piston means disposed within the coil. A pair of collars is attached to the ends of the coil, and the piston effects relative longitudinal axial movement of the collars and, hence, the respective ends of the coil tip. When the ends of the coil tip are so moved with respect to one another, expansion and contraction of the diameter of the coil tip results. In another embodiment of the invention, the expansion tip coil is actuated by an expandable and contractible bellows means disposed within the coil, instead of the piston means.Type: GrantFiled: June 7, 1995Date of Patent: July 4, 2000Assignee: Nadim M.
