Methods and systems for treating intracranial hypertension and related indications using an optic nerve stent or shunt
Embodiments of the present specification provide surgical methods and apparatuses to deploy at least one stent through an optic nerve sheath in order to maintain an opening/fenestration for intracranial fluid egress. The surgical method creates a fenestration, an opening, a slit, or a hole, through an optic nerve sheath of a human patient. The fenestration is created in a minimally invasive manner using an applicator, such as an endoscopic visualization apparatus, that includes a stent or shunt for deploying through the fenestration. The presently disclosed specification is indicated to treat papilledema and/or intracranial hypertension and to deliver therapeutic compositions through the optic nerve sheath.
Intra-aortic device
An intra-aortic device comprising a filter and a frame defining the shape of the filter, wherein the frame is intrinsically curved in a superior direction by a proximal superior bend and/or a distal superior bend, whereupon installation in an aorta, the M frame flattens.
RINGLESS WEB FOR REPAIR OF HEART VALVES
A ringless web is configured to repair heart valve function in patients suffering from degenerative mitral valve regurgitation (DMR) or functional mitral valve regurgitation (FMR). In accordance with various embodiments, a ringless web can be anchored at one or more locations below the valve plane in the ventricle, such as at a papillary muscle, and one or more locations above the valve plane, such as in the valve annulus. A tensioning mechanism connecting the ringless web to one or more of the anchors can be used to adjust a tension of the web such that web restrains the leaflet to prevent prolapse by restricting leaflet motion to the coaptation zone and/or promotes natural coaptation of the valve leaflets.
Soft tissue grafts, and methods of making and using same
Soft tissue grafts, packaged soft tissue grafts, and methods of making and using soft tissue grafts are disclosed. One soft tissue graft includes processed tissue material having first and second opposed surfaces. The first and second opposed surfaces are bounded by first and second edges. The first edge has a concave shape that curves toward the second edge. The second edge has a convex shape that curves away from the first edge. The first surface comprises a plurality of apertures. At least one of the apertures is formed from a multi-directional separation in the first surface. One method of making a soft tissue graft includes positioning a cutting die on a surface of tissue material, pressing the cutting die into the tissue material to cut the tissue material, and processing the cut tissue material to create processed tissue material.
Methods and Systems for Treating Intracranial Hypertension and Related Indications Using An Optic Nerve Stent or Shunt
Embodiments of the present specification provide surgical methods and apparatuses to deploy at least one stent through an optic nerve sheath in order to maintain an opening/fenestration for intracranial fluid egress. The surgical method creates a fenestration, an opening, a slit, or a hole, through an optic nerve sheath of a human patient. The fenestration is created in a minimally invasive manner using an applicator, such as an endoscopic visualization apparatus, that includes a stent or shunt for deploying through the fenestration. The presently disclosed specification is indicated to treat papilledema and/or intracranial hypertension and to deliver therapeutic compositions through the optic nerve sheath.
THREE- DIMENSIONAL WOVEN FABRIC IMPLANT DEVICES
A docking device includes a hollow cylindrical body portion having an internal surface and an outer surface. The hollow cylindrical body portion is formed of a three-dimensional (3D) woven fabric comprising a plurality of different types of fibers.
Arteriovenous fistula implant effective for inducing laminar blood flow
A vascular implant device configured to decrease turbulence in blood flow through an arteriovenous fistula is described. The implant includes an arterial section having a straight hollow tube, a venous section having a curved hollow tube divided into an orthogonal portion at the juncture of the arterial section, a curved portion, and a straight extension portion, and having a continual lumen and lumen surface. The curved portion curves approximately 90 degrees with respect to the arterial section, and the extension portion extends substantially parallel to the arterial section. A plurality of flow-conditioning tabs are located along the lumen surface in arrangements precisely designed to convert the turbulent blood flow that enters the venous section into substantially laminar flow, and to minimize oscillatory shear stress on the venous endothelium as the blood flow exits the device and enters the vein.
DEVICE AND METHOD FOR PREVENTING STENOSIS AT AN ANASTOMOSIS SITE
The present invention relates to treating or preventing stenosis at an anastomosis site. In one embodiment, the present invention is a stent is curved along the longitudinal axis for placement in and adjacent to the graft orifice. In a further embodiment, the stent is drug coated to allow delivery of antivasculoproliferative drugs directly to the vicinity of the graft orifice. In a further embodiment, the stent is expandable by use of an external wire. In another embodiment, the present invention is a kit comprising the specially configured stent together with a sleeve comprising a biocompatible matrix material and a pharmaceutical agent, wherein the sleeve is applied to the external surface of the vessel or graft, resulting in extravascular delivery of a pharmaceutical agent. Methods for treating or preventing stenosis at an anastomosis site by applying the extravascular sleeve and the intravascular stent are also provided.
Docking device made with 3D woven fabric
A docking device for a bioprosthesis is disclosed that can change shape and recover after a deforming stress is removed, that adjusts to surrounding conditions to accommodate different complex anatomic geometries, and that mitigates leakage around the bioprosthesis. The docking device can include a 3D woven fabric forming an internal surface, an outer surface, and a thickness therebetween. A filler can be coupled to the outer surface. A method for making a docking device is also provided. The method includes weaving a 3D woven fabric by interlacing a shape memory material, a low-melt thermoplastic polymer or resin having a melting point, and a high-tenacity biocompatible material; and pressing and heating the 3D woven fabric over a shape-setting mold at temperatures greater than the melting point of the low-melt thermoplastic polymer or resin.
IMPLANTABLE MEDICAL DEVICE WITH VISUAL ORIENTATION INDICATOR
An implantable medical device adapted to be implanted at an implantation site may be capable of being implanted in more than one rotational orientation at the implantation site. The implantable medical device includes an expandable body that is adapted to expand from a collapsed configuration for delivery to an expanded configuration for deployment, and a radiopaque indicator that is disposed relative to the expandable body. The radiopaque indicator is adapted to be have a first appearance if viewed in a first rotational orientation and a second, different appearance if viewed in a second rotational orientation that is different from the first rotational orientation. As an example, the implantable medical device may be a catheter-delivered replacement aortic valve.
