    摘要： An improved elastic band for ligating tissue within a living body comprises a central opening defining an axis. A first curved edge is formed between a first surface extending substantially parallel to the axis and a second surface extending substantially perpendicular to the axis. A method of ligating tissue within a living body using such a ligating band comprises the steps of positioning the elastic band, which has been stretched to increase the size of a central opening extending therethrough, adjacent to a portion of tissue to be ligated. The tissue to be ligated is then drawn through the central opening of the elastic band and the elastic band is released so that the size of the central opening decreases to grip the tissue received therein.

    摘要： The surgical instrument includes a distal tool, a rigid or flexible elongated shaft that supports the distal tool, and a proximal handle or control member, where the tool and the handle are coupled to the respective distal and proximal ends of the elongated shaft via distal and proximal bendable motion members. Actuation means extends between said distal and proximal member to control bending. A manually rotatable member rotates the instrument shaft and working member relative to the control handle. A locking member is supported from the control handle and has locked and unlocked states; in the unlocked state enabling control of the distal work member from the proximal control handle via the bendable members; and in the locked state, holding the bendable members in a pre-selected relative fixed position.

    摘要： A stent/graft catheter delivery handle comprising a housing and a trigger pivotally connected to the housing on one end of the trigger. Squeezing the free end of the trigger towards the handle housing shifts a pawl, which is engaged with grooves on the outer surface of a stent/graft delivery catheter, longitudinally along the length of the catheter. Shifting of the pawl has the effect of retracting the sheath of the catheter relative to the plunger (inner lumen assembly) of the catheter and thus deploying a stent/graft stored in a proximal end of the catheter.

    摘要： There is disclosed herein powder densifying apparatus comprising a pair of opposed gas-permeable belts arranged to either side of a common axis so as to define a generally convergent densifying zone between their adjacent faces. The belts are multiply supported spanwise by a plurality of opposed spaced apart support rolls, each opposed pair of rolls defining a densifying station therebetween. The gas-permeable belts are driven toward the convergent end of the densifying zone at substantially equal speeds while powder material to be densified is fed into the divergent end of the densifying zone at a rate sufficient to maintain a substantially complete fill thereof.
