Stabilized Fabric Material For Medical Devices
A stabilized fabric composed of a mesh or a woven fabric is disclosed as are methods of their manufacture, the manufacture of medical devices made using a stabilized fibers and stabilized medical devices are all disclosed. Fabrics can be stabilized by several techniques including: using mechanical, chemical and/or energetic fasteners at warp and weft intersections in the weave; by using various weaving techniques and fibers. Meshes can be stabilized when properly dimensioned and arranged junctions and struts of the necessary properties are used. All of these stabilized fabrics can be made of synthetic polymer materials such as ultrahigh molecular weight PE or PP and expanded PTFE.
Medical device and system having such a device
A medical device, having a body that is tubular at least in some sections. The body can be transferred from a compressed state into an expanded state and has a circumferential wall having at least one first lattice structure and one second lattice structure. The first lattice structure and the second lattice structure form separate layers of the circumferential wall, which are arranged coaxially one inside the other and connected to each other at least at points in such a way that the first lattice structure and the second lattice structure can be moved relative to each other at least in some sections. A system having such a device is also disclosed.
Intravascular stent, preparation method and use thereof
The present disclosure relates to an intravascular stent, preparation method and use thereof, and the intravascular stent comprises a positioning segment and a supporting segment, the positioning segment comprising a plurality of first repeating elements, the supporting segment comprising at least two supporting units and at least one connecting unit, the supporting unit comprising a plurality of second repeating elements, the number of the first repeating elements differing from the number of the second repeating elements, a plane formed by front ends of the plurality of first repeating elements being vertical to or intersecting with the axis of the intravascular stent. The intravascular stent of the present disclosure is particularly suitable for iliac vein, with good supporting effect for iliac vein and less damage to venous wall, and can effectively avoid forming in-stent secondary thrombosis after intravascular stent implantation. Moreover, the intravascular stent of the present disclosure can be well positioned in the iliac vein to improve the accuracy of the release, and it is simple for operation. The vascular stent of the present disclosure has the advantages of simple structure, convenient production and low cost, and thereby has important practical significance and good prospect in clinical application.
Y-SHAPED SACROCOLPOPEXY SUPPORT
A Y-shaped support has a head section having a first free end and a second end secured to a leg section, with the leg section having a first leg extending from the second end of the head section and a second leg extending from the second end of the head section. A first connector is provided as a first interlocking stitch, with the first interlocking stitch passed through open leg spaces of the first leg and open head spaces in the head section. A second connector is provided as a second interlocking stitch, with the second interlocking stitch passed through the aligned open leg spaces of the first leg and the second leg to connect the first leg to the second leg. The second end of the head section is located outside a space where the first leg is connected to the second leg.
Intravascular implants
A radially expandable, tubular stent, includes a first section having a first crush resistance force and a second section have a second crush resistance force, wherein the first crush resistance force is less than the second crush resistance force. The first section is connected to the second section to form a tube, connection of the first and second sections extending in an axial direction of the tube.
Hybrid stent
A stent includes a high radial/crush force segment and a highly flexible segment. In an aspect, a plurality of first ring struts connected such that each of the plurality of first rings comprises a sinusoidal pattern having a plurality of apices and troughs, each first ring connected to an adjacent first ring by at least one connector. The connector extends from a ring strut of the first ring from a position near an apex of the first ring to a ring strut of the adjacent first rings near an apex of the adjacent ring, and a second stent segment comprises a plurality of second rings connected to one another to form a series of second rings.
Hernia repair grafts having anti-adhesion barriers
Materials for soft tissue repair, and in particular, material for hernia repair. These materials may be configured as an implant, such as a graft, that may be implanted into a patient in need thereof, such as a patient having a hernia or undergoing a hernia repair surgical procedure. These grafts may include a first layer comprising a substrate (e.g., mesh) and a second layer comprising a sheet of anti-adhesive material. The layers may be attached with a plurality of relatively small attachment sites that are separated by regions in which the two layers are not attached, to provide a highly compliant graft.
MEDICAL SYSTEM FOR TREATING STENOSIS IN INTRACRANIAL VESSELS
The disclosure relates to a medical system for treating stenosis in intracranial blood vessels including a compressible and self-expandable implant for covering the stenosis, said implant having a lattice structure, at least some sections of which are provided with a cover made of an electrospun fabric, wherein the fabric has irregularly sized pores, and a balloon catheter for dilating the stenosis and/or introducing the implant into the blood vessel.
Tracheobronchial implantable medical device and methods of use
Devices and methods for treating a diseased tracheobronchial region in a mammal. The device can be a stent which can include a sustained-release material such as a polymer matrix with a treatment agent. The stent can be bioabsorbable and a treatment agent can be incorporated therewith. A treatment method can be delivery of a stent to a tracheobronchial region by a delivery device such as a catheter assembly.
Vascular implants and methods
The present invention is directed to vascular implants and methods for fabricating the same. The implantable devices include but are not limited to stents, grafts and stent grafts. In many embodiments, the devices include one or more side branch lumens interconnected with the main lumen.
