Implantable devices may include a single, first component or a plurality of components such as first and second components, the second component being flexibly coupled to the first component. A socket extends over one or more of the component(s), the socket being configured to enhance the inter-component interaction and/or including one or more exposed surface(s) configured to exhibit one or more tiers of foreign body responses within a range of possible foreign body responses.

Implantable component with socket

Embodiments of the present disclosure comprise occlusion and drug delivery devices and methods. One aspect of the disclosure comprises a drug delivery device comprising an inner expansion member and an outer drug delivery component. Another aspect of the disclosure comprises bioabsorbable, lumen-occluding implants.

Vascular occlusion and drug delivery devices, systems, and methods

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include a cord that is flexible and elongated defining a length. The cord may include a core having a porous surface and a porosity-reducing element on at least a portion of the core.

Sutures and related medical devices

The invention is an improved biocompatible surface for a variety of medical purposes. The biocompatible surface employs a unique tight microstructure that demonstrates enhanced cellular response in the body, particularly when placed in contact with blood. As a blood contact surface, the present invention can be beneficially employed in a wide variety of implantable devices and in many other devices and equipment that come in contact with blood.

Biocompatible surfaces and devices incorporating such surfaces

Articles comprising an expanded polytetrafluoroethylene membrane having serpentine fibrils and having a discontinuous coating of a fluoropolymer thereon are provided. The fluoropolymer may be located at least partially in the pores of the expanded fluoropolymer membrane. In exemplary embodiments, the fluoropolymer is fluorinated ethylene propylene. The application of a tensile force at least partially straightens the serpentine fibrils, thereby elongating the article. The expanded polytetrafluoroethylene membrane may include a microstructure of substantially only fibrils. The articles can be elongated to a predetermined point at which further elongation is inhibited by a dramatic increase in stiffness. In one embodiment, the articles are used to form a covered stent device that requires little force to distend in the radial direction to a first diameter but is highly resistant to further distension to a second diameter (stop point). A large increase in diameter can advantageously be achieved prior to reaching the stop point.

A functional TFE copolymer fine powder is described, wherein the TFE copolymer is a polymer of TFE and at least one functional comonomer, and wherein the TFE copolymer has functional groups that are pendant to the polymer chain. The functional TFE copolymer fine powder resin is paste extrudable and expandable. Methods for making the functional TFE copolymer are also described. The expanded functional TFE copolymer material may be post-reacted after expansion.
