  • Patent number: 10689745
    Abstract: A process of converting an outer layer of an object made of a refractory metal, such as titanium, into a carbide of the refractory metal. A molten metal, such as molten lithium, is placed adjacent the outer surface of the object. The lithium does not react with the titanium, nor is it soluble within the titanium to any significant extent at the temperatures involved. The molten lithium contains elemental carbon, that is, free carbon atoms. At high temperature, the carbon diffuses into the titanium, and reacts with titanium atoms to form titanium carbide in an outer layer. Significantly, no other atoms are present, such as hydrogen or oxygen, which can cause problems, because they are blocked by the molten lithium.

    Abstract: A cannula and method include a shaft portion having a proximal end, a distal end, a longitudinal axis and a lumen extending from the proximal end to the oppositely disposed distal end along the longitudinal axis. A hub is attached to the proximal end of the shaft portion and includes a transverse portion, which extends transversely relative to the longitudinal axis of the shaft portion. An opaque marker is disposed on the transverse portion at a position corresponding to an expanded size of an expandable element such that the opaque marker indicates the expanded size in an imaging system image.

  • Patent number: 10327899
    Abstract: A delivery device for percutaneously delivering a stented prosthetic heart includes a sheath, a handle, and adjustment device including a fine adjustment mechanism, and an outer stability shaft. The sheath defines a lumen and is configured to compressively constrain the stented prosthetic heart valve. The handle is coupled to the proximal portion of the sheath and includes an actuator mechanism coupled to a proximal portion of the sheath that is configured to selectively move the sheath relative to the housing to release the stented prosthetic heat valve. The adjustment device is coupled to the handle and includes an adjustment lumen through which the sheath and the handle slidably extend. The outer stability shaft is coupled to the adjustment device. The fine adjustment mechanism is configured to selectively move the handle and the sheath relative to the adjustment device and the outer stability shaft.

  • Patent number: 10327896
    Abstract: An expandable introducer sheath for passage of implant delivery catheters, such as catheters for delivery of prosthetic heart valves. The expandable sheath balances the amounts, shapes and positions of various stiff and elastic structures in the sheath to selectively program the expandability and buckling stiffness of the sheath. The expandable sheath can include, for example, an expandable tubular layer that includes alternating stiff and elastic wall portions of a single radial thickness. The combination of stiff and elastic wall portions allow for torque and push strength to advance the expandable sheath while at the same time accommodating temporary expansion. The expandable sheath can also be reinforced with a tubular layer of braided fibers or a stent structure for additional strength. Other embodiments include selective use of slots or gaps at the distal end of a stiff wall portion to enhance expandability and distribute strain.

  • Patent number: 10322208
    Abstract: Techniques for modifying the surface of implantable devices, such as bioprosthetic valves, to improve the biocompatibility of the implantable devices are provided. In particular, a customizable, non-fouling surface coating may be formed on the surface of implantable devices that improves the biocompatibility of the implantable devices and has the potential to further reduce the occurrence of complications for patients of all ages. Additionally, various molecules of interest to specifically promote endothelialization of the implantable device may be added to the surface coating, which may facilitate the formation of an endothelial layer on the surface of the implantable device that would naturally maintain a non-thrombogenic, non-immunogenic environment in the long-term.
