A transcatheter heart valve includes a paravalvular seal that is configured for transfemoral delivery. The valve includes an outer frame and the seal is formed from a plurality of outwardly extending fibers.

A knitted stent and a knitted stent system are disclosed, the knitted stent system comprising the knitted stent, a knitted stent (100) is formed by spirally coiling a knitted wire about an axis in an interlaced manner. The knitted wire includes at least one elastic metal tube (110), each elastic metal tube (110) defining a first lumen and having a wall in which release holes (111) in communication with the first lumen are formed. The first lumen can serve as a drug receptacle. A drug can be filled in the receptacle and released from the release holes (111). In this way, the knitted stent (100) can be used as a base of a drug-loaded stent, thus solving the problem of poor geometric compliance and fatigue resistance arising from the use of conventional drug-loaded stents.

A left coronary artery (“LCA”) stent system includes: a first guidewire having a first diameter; a second guidewire having a second diameter, which may be the same or different than the first diameter; a left main (“LM”) stent assembly including (i) a catheter including a saline/contrast solution lumen and a guidewire lumen sized to accept both the first and second guidewire diameters of the first and second guidewires, and (ii) an LM stent sized to be deployed within a patient's LM; a left anterior descending artery (“LAD”) stent assembly for insertion through a deployed LM stent and along the first guidewire; and a circumflex artery (“LCx”) stent assembly for insertion through the deployed LM stent and along the second guidewire.

A method of braiding a stent includes braiding a number of elongate filaments around a mandrel using tensioned braiding carriers without spooling the filaments to the tensioned braiding carriers to form a braided stent having atraumatic ends.

In some embodiments, a real-time event is detected and context is determined based on the real-time event. An application model is fetched based on the context and meta-data associated with the real-time event, the application model referencing a micro-function and including pre-condition and post-condition descriptors. A graph is constructed based on the micro-function. The micro-function is transformed into micro-capabilities by determining a computing resource for execution of a micro-capability by matching pre-conditions and post-conditions of the micro-capability, and enabling execution and configuration of the micro-capability on the computing resource by providing access in a target environment to an API capable of calling the micro-capability to configure and execute the micro-capability. A request is received from the target environment to execute and configure the micro-capability on the computing resource. The micro-capability is executed and configured on the computing resource, and an output of the micro-capability is provided to the target environment.

The present disclosure relates generally to stents and methods for managing passage of material through a body lumen. In some embodiments, a medical stent may include a stent body defined by a hollow tubular elongate structure extending along a central axis, the stent body including a first portion and a second portion. The medical stent may further include a control region between the first and second portions, wherein in a first configuration the hollow tubular elongate structure of the control region is in a closed, twisted configuration, and wherein in a second configuration the hollow tubular elongate structure of the control region is in an open, expanded configuration.
