A low-profile stent graft has a Type-III endoleak suppression effect, avoiding the problem with a stent graft which uses an extra-thin graft incurring enlarged needle holes or needle hole parts in a suture part. The stent graft has a proximate end, a distal end, and a lumen which is positioned between the proximate end and the distal end. The stent graft is formed by coupling a cylindrical graft to a stent with a suture. The cylindrical graft is formed from a fabric having a thickness of 10-90 &#x3bc;m. The elastic modulus of the suture is 40 cN/dtex or less.

Stent graft

Provided is a superfine polyester fiber containing at least 98 wt % of a polyethylene terephthalate component, and characterized by fulfilling the following conditions: (1) the reduced viscosity (&#x3b7;sp/c) is at least 0.80 dl/g; (2) the total fineness is 7-120 dtex, and the single filament fineness is no more than 0.5 dtex; and (3) the toughness parameter (X) indicated by formula (1) is at least 2.0, the tensile strength is at least 3.5 cN/dtex and the tensile elongation is at least 12%.=(tensile strength&#xd7;&#x221a;tensile elongation)/(total fineness&#xd7;single filament fineness)&#x2003;&#x2003;formula (1).

Superfine polyester fiber and tubular seamless fabric

Provided are novel polyurethane elastic fibers having a high recovery stress, low hysteresis loss, and high heat resistance. The polyurethane elastic fibers of the present invention are polyurethane elastic fibers formed from a polyurethaneurea obtained from a copolyalkylene ether diol produced from different Calkylene ethers; a diisocyanate; and a diamine, the polyurethane elastic fibers being characterized in that the polyurethaneurea has a hard segment percentage of 14.0% to 25.0% as defined by formula (1): hard segment percentage (%)=(urea moiety number-average molecular weight)/{(urea moiety number-average molecular weight)+(moiety segment number-average molecular weight)}&#xd7;100 (formula (1)).

Polyurethane elastic fiber

The object of the present invention is to provide a polyurethane film having heat adhesion and further having high stress retention and excellent elastic functions, and the polyurethane film of the present invention is a heat adherent polyurethane film wherein the thermal adhesion peeling stress indicated by a maximum stress when separating a film from a cotton fabric after hot-pressing the film to the cotton fabric at a temperature of 130&#xb0; C. under a pressure of 4 bar for 25 seconds is 5.88 N/cm or more and the stress retention at an elongation percentage of 200% indicated by a ratio of a stress (f) in recovery to a stress (f) in stretching at an elongation percentage of 200% in an S-S curve drawn when the film is stretched to an elongation percentage of 300% and then recovered is 40% or more.

Heat adherent polyurethane film

A feed line connecting circuit for selectively connecting first, second and third feed line connecting terminals under a predetermined current feeding condition comprises a first current detector connected between one of the first and second feed line connecting terminals and a central node for detecting a current over a predetermined value; a first switch connected between the one of the first and second feed line connecting terminals and the central node for connecting said one of the first and second feed line connecting terminals to the central node under an unpowered condition; a selective switch controlled by the first current detector, the selective switch having first and second contacts and a common contact connected to the third feed line connecting terminal, the common contact being connected to the first selective contact when the first current detector does not detect a current over the predetermined value, and to the second selective contact when the first current detector detects a current over the predetermined value; and a second current detector connected between the first selective contact of the selective switch and the central node to change the first switch so as to disconnect said one of the first and second feed line connecting terminals from the central node when detecting a current above the predetermined value.

Feed line connection circuit and optical transmission system

When a trouble occurs in a cable, a feeding pass for another cable is ensured. In a feeding pass switching circuit, optical fibers are respectively connected to the terminals A, B and C. When a negative current is applied to the system in a state where a BRANCH2 is put in an open circuit and a TRUNK is grounded, a relay K1 is activated, and then a relay K2 is activated. Successively, when a positive current is supplied from the TRUNK, a cable connected to the TRUNK and a BRANCH1 is fed from both terminals. When the positive current is supplied from the BRANCH1 in a state where the TRUNK is put in a open circuit and the BRANCH2 is grounded, a relay K3 is activated. Successively, when the negative current is supplied to the BRANCH2, a relay K5 is activated. In such a manner, the power is fed to each feeding pass from one terminal.
