Stented vascular graft
A vascular graft incorporating a stent into a portion of its length. While various materials may be used for the vascular graft, the graft is preferably an ePTFE graft. The stent is preferably a self-expanding stent, although it may alternatively be a balloon expandable stent. The vascular graft preferably has a continuous inner tubular liner that extends between the opposing ends of the graft and provides a continuous luminal surface for blood contact that is uninterrupted by seams or joints. The length portion of the graft that does not include the stent has a greater wall thickness than does the portion including the stent.
VALVE DELIVERY SYSTEM INCLUDING FORESHORTENING COMPENSATOR FOR IMPROVED POSITIONING ACCURACY
A system including a self-expanding prosthesis configured to foreshorten during deployment thereof and a delivery device configured to percutaneously deliver the self-expanding prosthesis. The delivery device includes a handle having an actuator thereon, an outer sheath including a proximal end coupled to the handle and a pusher shaft slidingly disposed within the outer sheath. The pusher shaft has a proximal end coupled to the handle and a distal end configured to releasably couple to the self-expanding prosthesis such that the self-expanding prosthesis axially moves therewith. The inner shaft has a distal portion of the inner shaft that is configured to receive a self-expanding prosthesis thereon. The outer sheath and the pusher shaft are configured to simultaneously move in opposing axial directions via actuation of the actuator on the handle to compensate for the foreshortening of the self-expanding prosthesis during deployment.
Endovascular interventions in neurovascular anatomy
Method of endovascular intervention in neurovascular anatomy of a patient including deploying an anchor of a tethering device in an anchoring vessel of a neurovascular anatomy, the anchor coupled to a tether extending proximally from the anchor. Method includes advancing a guide-sheath over the tether of the tethering device anchored in the anchoring vessel and attached to the tether, the guide-sheath includes at least one lumen and a distal opening from the lumen. Method includes advancing a treatment device through the lumen of the guide-sheath and out the distal opening from the at least one lumen and through an entrance of a target intracranial vessel, and deploying the treatment device at a treatment site within the target intracranial vessel without a combined therapy of two or more anti-platelet therapeutic agents during a peri-procedural period. Related systems, devices, and methods are disclosed.
Method and apparatus for treating critical limb ischemia
A system and method for treating critical limb ischemia (CLI) including a radiopaque micro stent disposed for cross ankle stenting as well as retrograde pedal/tibial artery access, in conjunction with antegrade access for the recanalization of impaired tibial vessels. A radiopaque medical device is constructed from a tubular-shaped body having a thin wall defining a specific strut pattern. In an additional aspect, the present apparatus introduces a new radiopaque medical device, such as a stent, wherein the tubular body includes a super elastic, nickel-titanium (nitinol) alloy.
DOUBLE-LAYER FIBROUS ANNULUS PATCH, PATCH CLAMP, SUTURE NEEDLE AND FISHBONE SUTURE
This invention relates to a double-layer fibrous annulus patch, a patch clamp, a suture needle and a fishbone suture. The inner layer foldable patch and the outer layer foldable patch are arranged and connected by a pair of crossed flexible connectors. Both ends of the two patches are connected by auxiliary connectors. A pair of auxiliary connectors are further arranged on both sides of the outer foldable patch, which can be used with the patch clamp to unfold the patch and secure it in place. With both patches in a folded state, the patch clamp is used to push the inner foldable patch through the rupture in the intervertebral disc into the annulus fibrosus and the patch unfolds within the annulus fibrosus. The outer layer foldable patch is unfolded on the outside of the annulus fibrosus and is fixed by two auxiliary connectors and fishbone sutures.
Annuloplasty device
An annuloplasty device is disclosed comprising first and second support rings being configured to be arranged as a coil in a first configuration around an axial direction, wherein the first and second support rings are configured to be arranged on opposite sides of native heart valve leaflets of a heart valve, wherein the first and second support rings are separated with a first pitch distance in the axial direction, in the first configuration, wherein the first and second support rings are configured to assume a contracted state having a second pitch distance in the axial direction being shorter than the first pitch distance, and wherein the first and second support rings are configured to be transferable between the first configuration and the contracted state to pinch the heart valve leaflets. A method of repairing a defective heart valve is also disclosed.
Native valve repair devices and procedures
A valve repair device for repairing a native valve of a patient includes a pair of paddles and a pair of gripping members. The pair of paddles are movable between an open position and a closed position. Each paddle comprises a metal loop that is moveable from a compressed condition where each metal loop has a first width to an expanded condition where each loop has a second width that is greater than the first width. The pair of gripping members are configured to attach to the native valve of the patient.
Systems and methods for treating cardiac dysfunction
A system for treating cardiac dysfunction can include an expandable device for insertion into a heart, a foot configured to contact a portion of the heart, a support frame, and a membrane coupled to the support frame. The support frame can include a plurality of radially expandable struts each having a first free end configured to extend beyond the foot and a second end coupled to the foot. The plurality of radially expandable struts can include a plurality of staggered stops, and each of the stops can be positioned on a respective one of the struts proximal to the first free end of the respective one of the struts. Method for treating cardiac dysfunction can include implanting the systems described herein into a chamber of the heart.
Methods for securing a transcatheter valve to a bioprosthetic cardiac structure
A spacer for creating a docking station for a transcatheter heart valve is provided. The spacer changes an effective diameter and/or a shape of an implanted bioprosthetic structure such as a bioprosthetic heart valve or annuloplasty ring, providing a supporting structure into which the transcatheter valve expands without over expanding. The spacer may be deployed through an interventional technique either through transseptal access, transfemoral access, or transapical access and is typically deployed at least in part on an inflow portion of the implanted bioprosthetic structure.
Collapsible leaflets for prosthetic heart valves
A prosthetic heart valve may include an expandable stent, a cuff attached to an annulus section of the stent, and a plurality of leaflets disposed within an interior region of the stent and attached to at least one of the cuff or the stent. The stent may have a plurality of cells connected to one another in a plurality of annular rows around the stent. The leaflets together may have a coapted position occluding the interior region of the stent and an open position in which the interior region is not occluded. Each leaflet may include a primary leaflet material, as well as features that reinforce specific regions of the leaflet.
