A stent including a mesh made of strands. The mesh has at least one radiopaque strand and at least one non-radiopaque strand, and the at least one radiopaque strand and the at least one non-radiopaque strand each have different diameters. Each strand has an index of wire stiffness EI, where EI is the mathematical product of the Young's modulus (E) and the second moment of area (I). The EI of all strands in the mesh is no more than five times the EI of the strand having the smallest EI of any of the strands.

Stents having radiopaque mesh

A stent delivery system includes an expandable stent, a catheter, and a sheath. The expandable stent includes proximal and distal ends, and a first interlock structure. The catheter includes an elongated member having a second interlock structure displaceably arranged about an outer surface thereof for engaging the first interlock structure of the stent. The sheath is mounted on the elongated member and is positionable in a transport position in which the sheath covers the stent mounted on the elongated member and a deploy position in which the stent is exposed.

Stent retaining systems

An atherectomy catheter directs particles generated by a cutting element into a collection chamber. A lumen configured to direct fluid into the tissue collection chamber.

Material removal device having improved material capture efficiency and methods of use

An implant delivery catheter enables permanent modification of the implant length in the vicinity of the treatment site prior to radial expansion thereof. The implant is releasable carried between inner and outer tubular members of the delivery catheter which, upon repositioning relative to one another using an actuator mechanism, impart any of tensile, compressile or torquing forces to the implant causing permanent modification of the implant length. In one embodiment, the circumference of the implant is substantially similar both before and after modification of the implant length. In another embodiment, the implant includes a plurality of strut sections interconnected by bridges which are capable of the deformation along the longitudinal axis of the implant.

Stretchable stent and delivery system

An intravascular medical device including an elongated member configured to be advanced along a vascular path of a patient, the elongated member having opposite first and second ends, the first end and second ends both being adapted for intravascular insertion, and the first end having a different structure than the second end. The elongated member has sufficient flexibility to be advanced through a human vasculature. Preferably, the first and second ends are adapted to have different operating characteristics. Depending on the operating characteristics needed for a particular procedure, a physician can insert either the first end portion or the second end portion of the elongated member into the patient's vasculature.

Double ended intravascular medical device

A distal protection device for use in a body lumen. The device includes a functional element which may be a filler or an occlusive element. The device includes means for controlling the movement and placement of the functional element along a guidewire. Motion of the guidewire can be independent of the motion of the functional element.

Distal protection devices having controllable wire motion

An implant delivery system has one or more interlock assemblies which connect the implant delivery catheter to the implant, an improved inner tubular member and an outer tubular member. The interlock assemblies, improved inner tubular member and outer tubular member cooperate to place the implant in tension during deployment, thereby reducing implant deployment force.

Implant and delivery system with multiple marker interlocks

The invention provides an embolic protection device for removing emboli from a blood vessel in a patient's body. The device comprises an elongate host element, an embolic protection element having a collapsed configuration and an expanded configuration, and a flexible tether connected to a distal end of the host element and to a proximal portion of the embolic protection element. The tether allows the host element to move axially and laterally relative to the embolic protection element over a limited range of motion when the embolic protection element is in an expanded configuration. The embolic protection device has a landing zone of 4 cm or less.

Embolic protection devices having short landing zones

An implant delivery system and method comprises an implant, for example, a stent, and a delivery catheter. The stent has a scaffold with a coating or a shell that retains the scaffold in a collapsed configuration. The coating or shell is made of a material that dissolves or biodegrades upon exposure to a dissolution or biodegradation media. The stent is used with an implant delivery system which has a catheter with a catheter, wherein the stent is mounted on the catheter shaft. The catheter shaft is configured to be withdrawn through the patient's vessel when the scaffold is in its expanded configuration. Advantageously, the implant is thereby prevented from changing length during implant delivery and implant deployment.

Stents and catheters having improved stent deployment

A stent for reducing the passage of emboli into body lumen once deployed includes a structural portion and a barrier portion. The structural portion, when expanded in a conduit, provides sufficient strength to maintain an open lumen in the conduit. The barrier portion reduces migration of emboli from the wall of the conduit through the structural portion and into the lumen. Stent delivery systems capable of delivering and deploying the stent are disclosed.

Stent having reduced passage of emboli and stent delivery system

A device, method, and system of deploying an embolic protection device at a location distal to a treatment site in a vessel of a patient. A delivery catheter is encircled by a sealing member which is expandable from a delivery configuration to a deployed configuration. The device creates a seal to prevent the flow of blood during the treatment of vascular disease. A distal protection element is delivered by the delivery catheter and deployed to filter or remove embolic debris.

Catheter with occluding cuff

Catheters, assemblies, and methods for delivering and recovering embolic protection devices. Catheters are provided that can be advanced over single length guide wires and which can be retracted over single length wire shafts of distal embolic protection devices. One catheter is a two-port catheter having two sidewall ports, a distal end port, and a proximal end port. The two-port catheter can be advanced over a guide wire threaded between the distal end port and the distal sidewall port. An embolic protection device wire shaft can be back loaded into the distal end port and out the proximal sidewall port. A three-port catheter includes a distal end port, and distal, intermediate, and proximal sidewall ports. The distal sidewall port can be dimensioned to accept passage of a filter body through the port. The distal end port can be dimensioned to accept only a guide wire to provide a smooth transition from the guide wire to the small profile distal end. The guide wire can extend between the distal end port and the intermediate port while the filter body shaft can extend through the proximal port, to be distally urged through the distal sidewall port. Another catheter embodiment is a slotted catheter, including a biased, normally open slot over most of its length. The slot can be sufficiently small to resist unwanted transverse movement of a wire through the slot. The slotted catheter can be retracted over a wire by forcing the wire through the resilient slot.

Rapid exchange catheters usable with embolic protection devices

An embolic protection device comprising an expandable structure and a catheter. The catheter has a distal region and a working channel dimensioned to slideably receive an interventional device. The expandable structure is attached to the distal region of the catheter. The expandable structure has an expandable working channel extension and a working channel opening, the expandable working channel extension has a proximal end and a distal end, the proximal end of the working channel extension is attached to a distal end of the working channel, and the distal end of the working channel extension forms the working channel opening. The working channel opening is disposed proximate an exterior surface of the expandable structure when the expandable structure is expanded. The working channel, working channel extension, and the working channel opening form a continuous lumen.

Embolic protection systems

An atherectomy catheter directs particles generated by a cutting element into a collection chamber. A paddle attached to the cutting element propels fluid distally in the tissue collection chamber.
