Publication number: 20180235788Abstract: Self-expandable, woven intravascular devices for use as stents (both straight and tapered), filters (both temporary and permanent) and occluders for insertion and implantation into a variety of anatomical structures. The devices may be formed from shape memory metals such as nitinol. The devices may also be formed from biodegradable materials. Delivery systems for the devices include two hollow tubes that operate coaxially. A device is secured to the tubes prior to the implantation and delivery of the device by securing one end of the device to the outside of the inner tube and by securing the other end of the device to the outside of the outer tube. The stents may be partially or completely covered by graft materials, but may also be bare. The devices may be formed from a single wire. The devices may be formed by either hand or machine weaving.Type: ApplicationFiled: March 20, 2018Publication date: August 23, 2018Applicant: BOARD OF REGENTS, THE UNIVERSITY OF TEXAS SYSTEMInventors: Hideki Hyodoh, Andras Konya, Kenneth C.

Publication number: 20100249902Abstract: The present invention provides a stent and tubular organ treatment device that can flexibly deform according to a curved portion of a tubular organ, contracts less in the longitudinal direction during insertion, and is easy to handle. A stent (1) is formed into a tubular form by arranging five tubular unit bodies in an axial direction and connecting them by a connecting filament (F). Each tubular unit is formed into a closed loop by cutting a metal wire to a predetermined length, bending it in a zigzag manner in a peripheral direction, and securely connecting both ends thereof. A tubular unit body (W) having two bent portions projected in the axial direction is connected to and rockably retained by a tubular unit body (U1). Similarly, a tubular unit body (V) is rockably retained by the tubular unit body (W), whereby the entire stent can easily deform into a curved shape.Type: ApplicationFiled: January 22, 2008Publication date: September 30, 2010Applicants: National University Corporation University of Fukui, Sapporo Medical UniversityInventors: Toyohiko Sakai, Hideki Hyodoh

Publication number: 20100174354Abstract: A stent placement device and a stent placement method, despite a simple structure thereof, can surely and readily deploy a stent by placing a distal end thereof prior to a proximal end thereof, having favorably low invasiveness, and smoothly insert and arrange the stent into a desired position, without damaging an internal lumen inner wall. A placement device 1 for deploying a stent 2 in an internal lumen includes a guide wire 3 which guides said stent 2 into a desired position in the internal lumen, a proximal tip 4 which is fixed at an intermediate position of said guide wire 3 and provided with a stent anchoring portion for anchoring said stent 2, and a stent converging and retaining member 5 which converges and retains a stent proximal end opening portion 2a of said stent 2.Type: ApplicationFiled: July 17, 2008Publication date: July 8, 2010Applicant: SAPPORO MEDICAL UNIVERSITYInventors: Hideki Hyodoh, Toyohiko Sakai

Patent number: 6409750Abstract: Bifurcated and trifurcated woven stents for insertion and delivery into a variety of anatomical structures, including the aortic-iliac bifurcation, the superior vena cava junction, and the inferior vena cava junction. The bifurcated stents includes a first leg formed from a first plurality of wires, a second leg formed from a second plurality of wires, and a common body formed from the first and second pluralities of wires. The wires may be nitinol. Biodegradable filaments may also be utilized. The angles created between the crossed wires is preferably obtuse. A variety of delivery devices formed from differently-sized tubes, portions of which may operate co-axially with each other, are also included.
