Stent And Stent Delivery Device
In one embodiment according to the present invention, a stent is described having a generally cylindrical body formed from a single woven nitinol wire. The distal and proximal ends of the stent include a plurality of loops, some of which include marker members used for visualizing the position of the stent. In another embodiment, the previously described stent includes an inner flow diverting layer.
METHODS FOR DEPLOYMENT OF AN IMPLANT
Methods are provided for the delivery of an implant into a body lumen of a patient. The method includes the steps of advancing a delivery device that includes a first tubular member housing an implant, a distal control member slidable within the first tubular member and releasably coupled with a distal portion of the implant, and an elongate grasper member slidable within the first tubular member and releasably coupled with a proximal portion of the implant. The method includes causing relative motion between the elongate grasper member and the first tubular member to expose at least a portion of the implant within the first tubular member, and then releasing the distal portion of the implant from the distal control member and the proximal portion of the implant from the elongate grasper member.
Implantable stent
Implantable stents that include strips that are each comprised of main struts connected by first connectors, and adjacent strips are connected by second connectors. The strut connectors have a structure, including areas of expanded or reduced width or thickness, to account for venous applications. When used for venous applications, the stents convey benefit from configurations that improve flexibility (due to the greater elasticity of venous applications) while maintaining enough stiffness to resist pressure on the venous structure in selected areas (such as for the May-Thurner syndrome). The stents include particular structural characteristics that are particularly advantageous for (although not limited to) venous applications.
METHODS AND APPARATUS FOR ENDOVASCULAR HEART VALVE REPLACEMENT COMPRISING TISSUE GRASPING ELEMENTS
A method for endovascularly replacing a patient's heart valve including the following steps: endovascularly delivering an anchor and a replacement valve supported within the anchor to a vicinity of the heart valve in a collapsed delivery configuration, the anchor having grasping elements adapted to grasp tissue in a vicinity of the heart valve; expanding the anchor, thereby rotating the grasping elements; and grasping the tissue with the rotating grasping elements.
Helical hybrid stent
An expandable helical stent is provided, wherein the stent may be formed of an amorphous metal alloy or other non-amorphous metal with a securement. The stent is formed from flat or tubular metal in a helical coiled structure which has an undulating pattern. The main stent component may be formed of a single helically coiled component. Alternatively, a plurality of helically coiled ribbons may be used to form a stent heterogeneous in design, material, or other characteristic particular to that stent. The helical tubular structure may be secured with a securement, such as a weld, interlock or a polymer, to maintain the helical coils in a tubular configuration. The helical coils of the main stent component may be spaced apart or nestled to each other-maintain the tubular shape of the helically coiled stent and prevent the polymer layer from sagging at any point between cycles of the coils.
DEVICES AND METHODS FOR TREATING CARDIOVASCULAR AND METABOLIC DISEASE
Devices and methods described herein may, among other uses, favorably cause the activation and/or deactivation of vascular baroreceptors in order to achieve a desired impact on a physiological condition, such as baroreflex-regulated conditions, hypertension, hypotension, nervous system disorders, metabolic disorders, cardiovascular disease, heart failure, cardiac arrhythmia, renal disease, respiratory disease, diabetes, and insulin resistance. The devices and methods may be used in concert with each other and/or other treatments, medications, interventions, or behavioral regimens. They may also be used in concert with devices and methods that perform or assist with assessing or measuring a mammal's blood pressure, assessing, measuring, or predicting the impact of the described methods and devices on the patient's condition (including blood pressure), and/or protecting the surrounding anatomy from adverse effects.
Stent for connecting adjacent tissues and manufacturing method thereof
The present invention relates to a connection stent and a method of manufacturing the stent. The connection stent includes: a body configured to form a plurality of cells through the intersection of wires, and provided in a hollow cylindrical shape; an upper head formed to extend from one end of the body to have a diameter larger than that of the body; and a lower head formed to extend from a remaining end of the body to have a diameter larger than that of the body. The upper head and the lower head are respectively placed to come into contact with insides of heterogeneous tissues. Accordingly, according to the present invention, there can be manufactured a stent which can connect heterogeneous tissues and form a bypass and which can provide sufficient expansion force and minimum axial force for the maintenance of the bypass formed as described above.

VASCULAR FLOW DIVERSION
Devices that can be delivered into a vascular system to divert flow are disclosed herein. According to some embodiments, devices are provided for treating aneurysms by diverting flow. An expandable device can comprise, for example, a plurality of connector sections and a plurality of bridge sections. Each of the connector sections may extend circumferentially about the expandable device and include a plurality of connector struts. Each of the plurality of bridge sections may be attached to and extend between two of the connector sections and comprise a plurality of parallel, non-branching, helical bridge members.
METHODS, SYSTEMS AND DEVICES FOR TREATMENT OF CEREBROSPINAL VENOUS INSUFFICIENCY AND MULTIPLE SCLEROSIS
Methods and devices for relieving stenoses in, or otherwise improving blood flow through, body lumens. Although applicable in a variety of different body lumens, the methods and devices of this invention are specifically useable for relieving stenoses in, or otherwise improving blood flow through, veins which drain blood from the brain for treatment of multiple sclerosis or other neurodegenerative disorders that are caused, triggered or exacerbated by venous occlusion or venous insufficiency.
