Medical appliances may be formed of multilayered constructs. The layers of the constructs may be configured with various physical properties or characteristics. The disposition and arrangement of each layer may be configured to create an overall construct with a combination of the individual properties of the layers. Constructs may be used to create vascular prostheses or other medical devices.

Layered medical appliances and methods

Fibrous materials and methods of manufacturing fibrous materials are disclosed. In particular, this application discloses methods of making and processing serially deposited fibrous structures, such as serially deposited fibrous mats. Serially deposited fibrous mats may be used in implantable medical devices with various characteristics and features. Serially deposited fibrous mats of various mat thickness, fiber size, porosity, pore size, and fiber density are disclosed. Additionally, serially deposited fibrous mats having various amounts of fiber structures (such as intersections, branches, and bundles) per unit area are also disclosed.

Serially deposited fiber materials and associated devices and methods

A stent or other prosthesis may be formed by coating a single continuous wire scaffold with a polymer coating. The polymer coating may consist of layers of electrospun polytetrafluoroethylene (PTFE). Electrospun PTFE of certain porosities may permit endothelial cell growth within the prosthesis.

Electrospun PTFE coated stent and method of use

Devices used to restrict flow within a blood vessel are disclosed. Devices within the scope of this disclosure include a braided lattice of nitinol wires that form self-expanding enclosures of an embolic structure. The devices may further include embolic particles disposed within the enclosures. Methods of deploying the devices with the embolic particles are disclosed. Methods of manufacturing the devices with the embolic particles disposed within the enclosures are disclosed.

Covered vascular plug

Sheets of material used in medical devices and filters are disclosed. The sheets may include a fibrous mat including a plurality of microfibers. The microfibers may include a polymer matrix and a plurality of additive particles. The additive particles may include carbon material particles, therapeutic micro particles, and any combination thereof. Medical devices and filters that use the sheets are disclosed. Methods of producing the sheets are also disclosed.

Fibrous constructs with therapeutic material particles

A vascular prosthesis deployment device and related methods are disclosed. In some embodiments the deployment device may include a delivery catheter assembly. The delivery catheter assembly may include a pliant member, wherein the pliant member is configured receive a vascular prosthesis. The pliant member may also be configured to aid in incrementally deploying a vascular prosthesis.

Pliant members for receiving and aiding in the deployment of vascular prostheses

Endovascular prostheses used to treat diseased blood vessels, such as arteries, are disclosed. In some embodiments, the endovascular prosthesis is configured to be implanted within the diseased blood vessels adjacent a diseased section. The endovascular prosthesis may include a selectively openable internal duct configured to sealingly receive an expandable endovascular prosthesis that extends into a side branch vessel of the diseased blood vessel.

Endovascular prosthesis with selectively openable internal duct

A medical insertion device includes an introducer assembly, a needle, and a housing. The introducer assembly includes a dilator coaxially disposed in a sheath, the dilator removably engaged to the sheath in an insertion configuration. The needle is coaxially disposed in the dilator, the needle having a distal tip and a proximal end coupled to a needle hub. The housing may be removably engaged to the dilator. The needle hub is movably disposed in the housing between a first locked position, a second locked position, and a third locked position.

Medical component insertion device including a retractable needle

Medical devices including vascular access kits and related methods are disclosed. In some embodiments, a vascular access system may include a first conduit, a second conduit, and a connector that is reversibly or irreversibly coupled to both the first and second conduits such that there is a continuous lumen from the first conduit and the second conduit. In some embodiments the vascular access system may include a connector where the inside geometry of the connector enhances laminar flow. The vascular access system, when implanted and assembled, may be a fully subcutaneous surgical implant.

Methods and systems for coupling conduits

An embolic filter balloon is disclosed. The embolic filter balloon may comprise an inflatable balloon portion. Further, the inflatable balloon portion may be coupled to a filter member. The embolic filter balloon may be disposed in a body lumen. In some embodiments, the embolic filter balloon may be configured such that when the inflatable balloon portion is at least partially inflated the filter member extends at least partially across the body lumen. Such a configuration may allow the embolic filter balloon, when deployed, to filter particles greater than a predetermined size from a fluid in the body lumen.

Methods of manufacturing an embolic filter balloon

A medical appliance or prosthesis may comprise one or more layers of rotational spun nanofibers, including rotational spun polymers. The rotational spun material may comprise layers including layers of polytetrafluoroethylene (PTFE). Rotational spun nanofiber mats of certain porosities may permit tissue ingrowth into or attachment to the prosthesis. Additionally, one or more cuffs may be configured to allow tissue ingrowth to anchor the prosthesis.

Rotational spun material covered medical appliances and methods of manufacture

Medical devices and related method for improving blood flow to regions of a patient are described herein. Some medical devices may include a first graft portion, a second graft portion, and a catheter portion disposed between the first graft portion and the second graft portion. The medical device may be implanted into a patient to establish a non-natural flow path.

Subcutaneous vascular assemblies for improving blood flow and related devices and methods

Medical devices including vascular access kits and related system and methods are disclosed. In some embodiments, a vascular access system may include a first conduit, a second conduit, and an expandable stent that is coupled to both the first and second conduits such that there is a continuous lumen between the first conduit and the second conduit. Methods of deploying the vascular access system within the body of a mammal, more particularly, a human patient are disclosed. Methods of bypassing a section of vasculature of a mammal, more particularly, a human patient are disclosed. The vascular access system, when implanted and assembled, may be a fully subcutaneous surgical implant.

Methods and systems for facilitating laminar flow between conduits

Medical appliances including reinforcing bands and radiopaque marker bands are disclosed. In some embodiments, bands may comprise two or more material layers. A first layer may control the mechanical properties of a multilayered marking band, and a second layer may exhibit greater radiopacity than the first layer. Bands may also comprise a single layer.

Single and multilayer bands and related methods

A medical appliance or prosthesis may comprise one or more layers of electrospun nanofibers, including electrospun polymers. The electrospun material may comprise layers including layers of polytetrafluoroethylene (PTFE). Electrospun nanofiber mats of certain porosities may permit tissue ingrowth into or attachment to the prosthesis.
