Abstract: Aspects of an expandable sheath can be used in conjunction with a catheter assembly to introduce a prosthetic device, such as a heart valve, into a patient. Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with a tubular inner liner wound in a spiral configuration such that a plurality of protrusions is disposed in an overlapping portion of the sheath. The disclosed sheath is configured to expand from a predetermined rest diameter dr to an expanded diameter de during application of a radial outward force by passage of a medical device through the sheath.

Abstract: Provided herein are nanoparticles which enhance the immunogenicity of antigens for use in Beta coronavirus (e.g., MERS-CoV, SARS-CoV-1, or SARS-CoV-2) vaccines, as well as immunogenic compositions comprising the antigen nanoparticles and additional adjuvants for further enhancing immunogenicity.

Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with a tubular inner liner wound in a helical scroll slidable configuration. The disclosed sheath is configured to expand from a predetermined rest diameter dr to an expanded diameter de during the application of a radial outward force by passage of a medical device through the sheath.

Abstract: Various systems, devices, and methods are described herein pertaining to expandable sheaths. Sheath aspects are described that include a flexible sheath tip that is expandable and bendable. In some aspects, the sheath includes a radially expandable proximal end and a radially expandable distal end. In some aspects, the sheath tip includes a plurality of layers that expand to accept a medical device traveling axially and bi-directionally therethrough with minimal deformation of the sheath tip.

Such aspects can minimize trauma to the vessel by allowing for temporary expansion of a portion of the introducer sheath to accommodate the delivery apparatus, followed by a return to the original diameter once the prosthetic device passes through. Some aspects can include a sheath with a tubular inner liner wound in a spiral configuration at least a portion of the outer surface of the sheet comprises a plurality of bonding sites that are at least partially embedded within the sheet and disposed such that the outer surface of the sheet in the overlapping portion is substantially free of the plurality of bonding sites.

Abstract: A sub-system and method to receive input image pixel amplitude data at an input pixel resolution and to output image pixel amplitude data in one or two dimensions at a higher pixel resolution includes a computer system-executable algorithm with user-programmable coefficients. The programmable coefficients are user-selectable according to the nature and quality of the input image data such that sharpness of the output image data can be at least partially tailored to the image.

Abstract: Provided are an online networking system for an efficient operation of restaurants and a method therefore, in which restaurant customers and food material providers input order sheets and estimations of food material prices into a website and restaurants receive the order sheets and the estimations via facsimile so that restaurants serve more customers in circumstances of limited equipment, staffs, place, and time, and purchase food materials from the food material providers presenting a lowest price. The online networking system includes a service provider for operating and managing a web server that provides the website, restaurant customers, food material providers, and the restaurant connected to the web server via Internet terminals and a facsimile.
