  • Publication number: 20140222128
    Abstract: A system/assembly for delivery and deployment of an inflation expandable stent within a vessel, comprising a catheter having proximal and distal ends; a stent, inflation expandable from a delivery diameter to a deployment diameter, such that the delivery diameter is reduced from the deployment diameter for conforming the stent to the catheter, such that the stent, in its delivery diameter, is coaxially mounted on the catheter near the catheter distal end; an expandable inflation means coaxially mounted on the catheter axially within the stent, for expansion of the stent from the delivery diameter to the deployment diameter upon application of fluid deployment pressure to the inflation means; and a securement component coaxially mounted on the catheter, axially within the expandable inflation means, the securement component designed and adapted to provide a securement pressure to the stent in the delivery diameter to maintain the stent in position on the catheter during delivery to the deployment site.

  • Publication number: 20130014061
    Abstract: In one aspect, a computer-implemented method for use in controlling an operating environment includes: scoring a plurality of events detected within the operating environment to indicate an objective importance for a decision maker to address; presenting to the decision maker the scored events ranked relative to one another by their scores; receiving a selection by the decision maker of a particular one of the ranked events; scoring a plurality of alternative options to the selected event; presenting to the decision maker the options ranked relative to one another by their scores; receiving a selection by the decision maker of a particular one of the ranked options. In other aspects, a computing apparatus is programmed to perform such a method and a program storage medium is encoded with instructions that, when executed by computing device, perform such a method.

  • Patent number: 8206372
    Abstract: A tubular transition member having an annular wall with at least one cut extending through the annular wall is disclosed for controlling a transition in stiffness of a catheter from a stiffer more pushable proximal section to a more flexible and trackable distal section and increasing kink resistance. The transition member may extend across the junction formed between the stiffer proximal section and the more flexible distal section. The transition member may be used in conjunction with any type of catheter including single-operator-exchange type catheters, over-the wire type catheters, and/or fixed-wire type catheters.

  • Patent number: 8152819
    Abstract: An angioplasty and stent delivery system to facilitate introduction and placement of a stent, including a catheter having an expandable distal portion constructed and arranged for expanding the outer diameter of the catheter from a contracted state to an expanded state: a stent positioned around the distal portion of the catheter having a contracted condition and being expandable to an expanded condition, and being sized in the contracted condition to closely surround the catheter in the contracted state, the expandable distal portion of the catheter including a balloon within which or over which there is included on a catheter shaft at least one axially movable or enlargeable body of a diameter larger than the catheter shaft to which the stent and balloon are fitted, as by crimping, for holding the stent in place until it is released therefrom by expansion of the balloon.

  • Patent number: 7115183
    Abstract: A spiral cut transition member is disclosed for controlling the transition in stiffness of a catheter from a stiffer more pushable proximal section to a more flexible and trackable distal section and increasing kink resistance. The transition member has a spiral cut provided therein to vary the flexibility of the transition member over its length. The pitch of the spiral cut can be varied to facilitate a gradual transition in flexibility along the catheter. The transition member may be used in conjunction with any type of catheter including single-operator-exchange type catheters, over-the wire type catheters, and/or fixed-wire type catheters.

  • Patent number: 6769161
    Abstract: A stent crimper comprising a plurality of crimping members extending between a first support and a second support. The first and optionally the second supports has an opening therethrough sized to allow a stent therethrough. The first and second supports extend from a base. The crimping members are disposed about the circumference of a circle everywhere along the length of the members. Finally, the flexible members extend through a bore in a die. The die is movable in an axial direction along the flexible members.
