RADIALLY SELF-EXPANDING STENTS
Described herein are radially self-expanding stents. The disclosed stents can be used to widen arteries and/or veins of a patient to counteract or combat narrowing of the arteries and/or veins associated with certain congenital diseases, such as aortic coarctation. As an example, the disclosed stents are configured to be placed at or near a narrowed portion of the aorta where the stent produces a radial outward force on the aorta. The radial force produced by the stent widens the aorta and causes the stent to expand with the aorta. The disclosed stents can be crimped to relatively small sizes for placement in small patients (e.g., less than about 10 kg in size) and can be configured to expand to widen the aorta and to accommodate growth in the patient.
Modular valve prosthesis with anchor stent and valve component
A modular valve prosthesis includes an anchor stent and a valve component. The anchor stent includes a self-expanding tubular frame member configured to be deployed in the aorta and a proximal arm component extending from a proximal end of the tubular frame member and configured to be deployed in the sinuses of the aortic valve. The anchor stent further includes attachment members extending from an internal surface of the tubular frame member. The valve component includes a valve frame configured to be deployed within the tubular frame member of the anchor stent such that the valve frame engages with the attachment members of the tubular frame member and a prosthetic valve coupled to the valve frame.
Delivery device and method of delivery
A delivery device can provide sequential delivery of a plurality of intraluminal devices held in a compressed state on the delivery device. Delivery platforms on the delivery device can hold an intraluminal device in a compressed position and be positioned between pusher bands that may also be radiopaque markers. A post deployment dilation device can be included. The post deployment dilation device can be a plurality of expansion filaments, a bellows, or a balloon. An intravascular device deployment method can include allowing a self-expanding intravascular device to expand, aligning the post deployment dilation device under the intravascular device, and causing the post deployment dilation device to expand radially to push outward on the intravascular device.
Alternative use for hydrogel intrasaccular occlusion device with vertically oriented reinforcement members for structural support
A device for endovascular treatment to ameliorate aneurysm recurrences by deploying a treatment mesh having a plurality of vertically oriented elongated support reinforcement elements that are substantially parallel and oriented upon a plane in communication with the mesh. Upon deployment, the array of distal ends of the support extensions and reinforcements are substantially oriented upon a plane, which plane is in substantially the same orientation as the opening of the aneurysm into which the device was deployed. The treatment mesh may incorporate a coating of hydrogel, optionally impregnated with pharmaceutical compounds.
Prosthesis with branched portion
Examples of prostheses are provided having an internal branch. A tubular graft body of the prosthesis defines a main lumen extending between an inflow end and an outflow end of the graft body. A stent structure is coupled along the graft body. A trough is at least partially defined by a trough wall extending into the main lumen from a sidewall of the graft body. A side branch defines a branch lumen and extends from the trough within the main lumen towards one of the inflow or outflow ends of the graft body. A branch lumen facing surface of the trough wall is a continuous surface with an outer surface of the sidewall of the graft body. A boundary of the trough may be configured to provide a smooth transition surface between the trough and the sidewall.
Stent
A stent includes a cylindrical main body portion, a linkage portion, and a marker attachment portion. The main body portion extends in an axial direction. The linkage portion extends from an end of the main body portion in the axial direction. The marker attachment portion is linked to the main body portion through the linkage portion. The linkage portion includes a bent portion tilting the marker attachment portion outward in a radial direction of the main body portion.
Vascular Medical Device, System And Method
The present application discloses a covered stent and a method for navigating the covered stent to a branch vessel, the covered stent comprising a main body and at least one lateral side branch connected to the main body, wherein the lateral side branch is flexible and expandable. A system of covered stents and a method for interconnecting the covered stents is also disclosed.
READY-MADE BIOMEDICAL DEVICES FOR IN VIVO WELDING
Disclosed herein is a unique family of medical implants which are engineered outside of a subject's body into a form which may be manipulated in vivo. The implants comprise a region of at least one weldable material which allows welding of the implant to a polymeric material introduced into the body prior to, together with or after the implant has been positioned.
GRAFT WITH EXPANDABLE REGION AND METHODS OF MAKING AND USING THE SAME
A vascular graft suitable for implantation, and more particular to a vascular graft having an expandable outflow region for restoring patency of the graft after implantation into a body lumen.
Methods and apparatus for luminal stenting
Described herein are flexible implantable occluding devices that can, for example, navigate the tortuous vessels of the neurovasculature. The occluding devices can also conform to the shape of the tortuous vessels of the vasculature. In some embodiments, the occluding devices can direct blood flow within a vessel away from an aneurysm or limit blood flow to the aneurysm. Some embodiments describe methods and apparatus for adjusting, along a length of the device, the porosity of the occluding device. In some embodiments, the occluding devices allows adequate blood flow to be provided to adjacent structures such that those structures, whether they are branch vessels or oxygen-demanding tissues, are not deprived of the necessary blood flow.
