    摘要: A method and system for maintaining the position of a guiding member, such as a guidewire, within a patient's vascular system, particularly within a guiding catheter disposed within the patient's vascular system, while an intravascular catheter slidably mounted on the guiding member is withdrawn and a replacement catheter is advanced over the guiding member. One presently preferred embodiment includes a guiding sheath having an inner lumen extending the length thereof with an engaging device slidably disposed with the guiding sheath. The guidewire engaging device is torqued from its proximal end which extends out of the proximal end of the guiding catheter so that the flexible distal end wraps around the guidewire tightly enough to maintain the position of the guidewire while withdrawing or advancing a catheter over the guidewire. The distal portion of the guidewire engaging device is preferably a pseudo elastic NiTi alloy which is in a stable austenite phase at body temperature (37.degree. C.) and which exhibits a stress-induced transformation from the austenite phase to a martensite phase.

    摘要: An embolic filtering system includes a guide wire, a filter device disposed on the guide wire, a sheath adapted to maintain the filter device in an unexpanded position and a torque device having a lumen for receiving the guide wire and a locking mechanism for locking the torque device to the guide wire. The torque device may include a side port adapted to receive the proximal end of the sheath to allow a portion of the guide wire to shear the sheath from the guide wire through retraction of the sheath through the side port. The torque device may include an extension arm having a distal opening adapted to receive both the guide wire and the sheath. A second lumen may be used to allow a portion of the guide wire to shear the sheath away from the guide wire through retraction of the sheath through the second lumen.

    摘要: A self-expanding cage for use in conjunction with an embolic filtering device includes a circumferential member adapted to expand from an unexpanded position to a expanded position within the patient's body vessel. A proximal strut and distal strut are attached to the circumferential member to form the cage. A plurality of proximal and distal struts may be attached the circumferential member. Additionally, a second circumferential member can be attached to the first circumferential member. Each circumferential member can be connected by a single or a plurality of connecting struts. One embodiment of the cage utilizes a single wire to form to the cage. A delivery system attached to the single wire cage moves the cage and its associated filter element between the expanded and unexpanded positions through relative movement of the distal delivery system. This can be accomplished by either torquing the guide wire onto which the expandable cage is mounted or by longitudinally moving a tubular member which forms part of the delivery system longitudinally in relation to the guide wire.

    摘要: A guide wire having a damped force vibration mechanism which isolates vibrations or shockwaves which otherwise would be transmitted along the length of the guide wire to its distal end. The damped force vibration mechanism helps absorb some of the energy created during the exchange of a delivery catheter or an interventional device on the guide wire or any shock or force generated from an external source. The damped force vibration mechanism absorbs vibrations or shock which would otherwise act on medical devices attached near the distal end of a guide wire. The damped force vibration mechanism may consist of a reduced segment on the guide wire which can be made from a material such as superelastic or plastically deformable, biocompatible materials. The damped force vibration mechanism can have a relatively straight configuration or can have a wave-shaped form, or other shape which helps absorb vibratory motion.

    摘要: Methods, devices and systems are provided for modeling product volume penetration. A system embodiment includes a remote client operably connected to a server, having a number of client files, and an input device. A set of computer executable instructions are operable on the system for projecting product penetration of a product in a client file at a selectable point in time from a product launch or other starting point, based on a set of purchase data for the product. The set of computer executable instructions are operable for receiving the set of purchase data and graphically displaying the set of purchase data as a volume of product sales versus a number of time increments from the starting point. The set of computer executable instructions are further operable for mapping a curvilinear function to the graphically displayed set of purchase data by applying a function expressed as f(t)=s×tB.

    摘要: A system used in a blood vessel when an interventional procedure is being performed in a stenosed or occluded region, which is capable of capturing embolic material which may be released into a blood vessel during a therapeutic interventional procedure at the site of a lesion in the blood vessel. The system is adapted to be utilized in a collateral blood supply system adapted to enable the flow of blood to bypass the blood vessel upon blocking thereof and to enable the reverse flow of blood through the blood vessel upon unblocking thereof. The system includes a guide wire, including a distal end, adapted to be positioned in a blood vessel relative to an interventional procedure site. A guide catheter, including a distal end, is adapted to enable the interventional procedure to be performed, and to be inserted over the guide wire and through a patient's vasculature to a position in the blood vessel relative to the interventional procedure site. An occluding device for occluding and blocking a blood vessel at a location relative to the interventional procedure site is adapted to be positionable at a location relative to he interventional procedure site, to be expandable so as to prevent and block the flow of blood past the occlusion, and to enable the capture of embolic material which may be released into the blood in the blood vessel during the therapeutic interventional procedure, and to be contracted to unblock the blood vessel and enable the recovery of captured embolic material.
