Abstract: A stent delivery system includes a self expanding stent positioned about a distal support segment of a catheter, which includes a proximal segment. A constraint has a wrapped configuration, which has a hollow elongated shape, and an unwrapped configuration, which is a continuous length of a strip. The stent is in contact with, and held in a compressed state by, the constraint in the wrapped configuration, and the stent is in an expanded state out of contact with the constraint in the unwrapped configuration. The constraint may move from the wrapped configuration toward the unwrapped configuration responsive to tension in a control line connected to one end of the strip.

Abstract: The present invention relates generally to expandable medical devices including a light-activated shape-memory polymer. In certain embodiments, the devices include, for example, balloon catheters, used to treat narrowed or obstructed portions of a body vessel, and retrieval devices, used to remove obstructions from a body vessel. Certain aspects of the invention relate to methods of manufacturing and using such devices.

Abstract: An aortic stent graft includes a stent with a framework attached to a fabric tube by a plurality of suture ties. The fabric tube includes a plurality of discrete attachment areas that are at least partially surrounded by at least one permeable graft area. The fabric tube is one of a weave and a knit of thermoplastic yarn. Each of the suture ties associated with the discrete attachment areas at least one of penetrates through and encircles a respective one of the discrete attachment areas. The weave or knit of the discrete attachment areas is identical to that of the permeable graft area with an exception that a wall thickness of each of the discrete attachment areas is flattened relative to, and thinner than, a wall thickness of the permeable graft area.

Abstract: Disclosed herein are systems and methods for delivering a medical device to a body vessel of a patient. The medical device may be a stent graft, and the delivery assembly may include at least one loop that connects an end stent of the stent graft to a trigger wire of the delivery assembly, thereby providing indirect connection between the device to be delivered and the trigger wire.

Abstract: A low profiled stent delivery system includes a balloon catheter with a balloon mounted at a first location, and a balloon expandable stent crimped about the balloon catheter at a second location. The stent expands from a crimped state to a less than fully expanded state responsive to movement of an auxiliary expander from a first configuration to a second configuration. An inner diameter of the stent in the less than fully expanded state is greater than an outer diameter of the balloon in a deflated state. After repositioning the balloon within the less than fully expanded state, the balloon is inflated to fully expand the stent.

Abstract: The present embodiments provide a system for controlled release of a portion of a stent. In one example, the system comprises a stent having proximal and distal regions, and a first barb coupled to the stent. A trigger wire restrains a portion of the stent in a delivery state. The system further comprises a barb release wire having proximal and distal regions, and an engagement region disposed therebetween. The distal region of the barb release wire is coupled to the trigger wire, and the engagement region of the barb release wire is disposed around a portion of the first barb to restrain the first barb in the delivery state. In one example, distal retraction of the trigger wire causes a simultaneous distal retraction of the barb release wire.

Abstract: An active implantable medical device comprises an expandable stent, a flexible cover material positioned on at least an outer surface of the expandable stent, a nanoscale source of electrical energy embedded within the cover material, where the nanoscale source of electrical energy is mechanically activatable to produce the electrical energy, and antimicrobial particles distributed on or within a surface region of the cover material. The antimicrobial particles are electrically connected to the nanoscale source of electrical energy. When the active implantable medical device is placed in a body vessel and exposed to pressure changes and/or mechanical stresses, mechanical activation of the nanoscale source occurs, thereby enabling production of the electrical energy and powering of the antimicrobial particles.

Abstract: A medical device, such as a prosthesis, and method of forming the same are disclosed. The medical device includes a cover material and a reinforcement element, and may include a stent frame structure. The reinforcement element includes a plurality of bends disposed about a pattern axis. The pattern axis is arranged helically along the cover material.

Abstract: The disclosure is directed to a system for maintaining hemostasis during introducing or withdrawing an interventional device. The system includes a housing. The housing includes a first end, a second end and a side wall defining a housing chamber. The system also includes a first funnel-shaped member disposed at least partially within the housing chamber. The first funnel-shaped member includes an inner portion, a middle portion and an outer portion. The inner portion of the first funnel-shaped member includes an elastic orifice, which is aligned with the through channel of the housing. The first funnel-shaped member includes an open configuration and a closed configuration. When the first funnel-shaped member is in the closed configuration, the elastic orifice is substantially closed, and when the first funnel-shaped member is in the open configuration, an interventional device is introduced through the system and the elastic orifice is open.

Abstract: A bifurcated stent graft includes a stent graft body that defines exactly one main body opening and at least two exit openings. The stent graft body includes at least one stent attached to a graft fabric material, and includes a dividing wall that divides a combined flow path, into a first flow path and a second flow path that each terminate at one of the respective exit openings. The dividing wall includes a thickness profile that terminates at a leading edge radius that extends across a width of the combined flow path.

Abstract: In one aspect, a radiopaque marker for a medical implant, such as a stent graft for aortic aneurism repair, includes a first radiopaque component connected to a second radiopaque component by a connection. The first radiopaque component includes a non-biodegradable radiopaque body. The radiopaque marker has a first configuration and a second configuration that differ from one another in at least one of volume and shape such that the first and second configurations produce different radiographic images. This change in radiopacity can provide useful information to a surgeon in the event that reintervention becomes necessary.
