摘要： Nickel-titanium alloys that have been deep drawn in a cold working process have linear pseudoelastic behavior without a phase transformation or onset of stress-induced martensite. A medical device made from a structural element which has been deep drawn and subsequently formed into a desired medical device geometry will experience such linear pseudoelastic behavior.

摘要： The present invention is directed to a guidewire having an elongate core member with a proximal section and a distal section. The distal section has at least one tapered segment, wherein the elongate core member tapers distally to a reduced diameter. Preferably, the tapered segments of the distal section of the elongate core member are marked with radiopaque markers to indicate where a tapered segment begins or ends. A proximal coil having a rectangular cross section and at least one distal coil having a round cross section are disposed around at least a portion of the distal section of the elongate core member. The proximal end of the proximal coil is attached to the distal section of the elongate core member. The distal coils can be made of a material that is radiopaque or non-radiopaque. If one of the distal coils is radiopaque, it may be made from a radiopaque material or it may be made of a hollow tube of non-radiopaque material that is filled with material that is at least partially radiopaque. The proximal end of the distal most coil is attached to the distal end of the proximal coil, and the distal end of the distal most coil is attached to the distal section of the elongate core member.

摘要： An expandable cage used in conjunction with an embolic filtering device has a strut configuration including a proximal strut assembly coupled to a distal strut assembly. A filter can be attached to the distal strut assembly which has an inlet opening. The proximal strut assembly is “offset” from the distal strut assembly in that these proximal struts extend substantially along the vessel wall of the patient, rather than being “centered” in the body vessel when the cage is expanded in a body vessel. As a result, there is little cage structure directly in front of the opening of the filter, resulting in a virtually unobstructed opening for the filter.

摘要： Cold worked nickel-titanium alloys that have linear pseudoelastic behavior without a phase transformation or onset of stress-induced martensite as applied to a medical device having a strut formed body deployed from a sheath is disclosed. In one application, an embolic protection device that employs a linear pseudoelastic nitinol self-expanding strut assembly with a small profile delivery system for use with interventional procedures is disclosed. Linear pseudoelastic nitinol is used in the medical device as distinct from non-linear pseudoelastic (i.e., superelastic) nitinol. The expandable strut assembly is made from a small diameter tubing of cold worked nickel-titanium alloys. The self-expanding struts that deploy the filter element is laser cut from a large diameter cold worked nickel-titanium alloy, then joined to the small diameter tubing.

摘要： An inner support structure for an embolic filtering device includes a tubular member having a first support region for supporting the proximal portion of a filter assembly and a second support region for supporting the distal portion of the filter assembly. The inner support structure facilitates rotation and restricts longitudinal movement of the embolic filtering device relative to a guide wire. Alternatively, the inner support structure includes a bushing coupled to the guide wire and a sleeve with a head on its proximal end positioned within a cavity in the bushing, thereby facilitating rotation and restricting longitudinal movement of the sleeve. The proximal portion of the filter assembly is supported on the sleeve. A sleeve for retaining the struts of an expandable cage of the embolic filtering device includes a central lumen for positioning the sleeve onto a guide wire and peripheral lumens for positioning and retaining the struts.

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： A self-expanding basket for use in conjunction with an embolic filtering device has a proximal set of struts which are connected to a distal set of struts by a bending region which provides enhanced bending characteristics to the basket. The bending region can be formed by intermediate links which are extremely flexible and bendable to allow the basket to be delivered through tortuous anatomy. The intermediate links are extremely flexible and create a mechanical hinge-like connection between the proximal and distal strut assemblies. The basket thus is capable of substantial bending when being delivered through the patient's vasculature and will bend and conform to the patient's anatomy once positioned for filtering purposes. The intermediate links can also lengthen, when needed, when positioned in a curved vessel in the patient's vasculature, when needed. As a result, the basket will easily conform to a curved body vessel to maintain proper wall apposition of the filtering element with the wall of the body vessel.

摘要： A deformable sheath is attached to a catheter and introduced intravascularly to be expanded against an arterial wall and entrap plaque therebetween. A stent is subsequently deployed within the expanded sheath and the sheath is then withdrawn from within the vasculature to leave the stent expanded against the arterial wall with the plaque entrapped therebetween.

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.
