The present disclosure relates to a medical delivery device that includes a barrel having an inner surface, a plunger rod having a distal end inserted within the barrel, and a stopper attached to the distal end of the plunger rod and contacting at least a portion of the inner surface of the barrel. In at least one embodiment, the inner surface is hydrophilic. The stopper may include an elastomeric body, one or more polyethylene layers, and two or more ribs laminated with the one or more polyethylene layers. In some embodiments, the contact width between at least one rib having a sealing surface and the portion of the inner surface of the barrel measured at a compressibility of greater than about 7.9% of the stopper is less than about 1.0 mm.

A device for treating disease along a main vessel and at least one branch vessel extending from the main vessel includes a branch member for deployment in the branch vessel, the branch member having a branch lumen; and a main body for deployment in the main vessel. The main body has a generally tubular wall extending generally longitudinally between opposite first and second ends. The wall has an internal surface defining a main lumen and an opposite outer surface. The wall has a recessed portion that is recessed relative to the outer surface of the wall and positioned between the first and second ends of the main body. The main body has an opening formed in the recessed portion of the wall for receiving the branch member therethrough such that the branch lumen is in fluid communication with the main lumen.

An implantable medical device comprising a first frame component. The first frame component including a first set of elongate elements configured to conform to an anatomy of a patient. The implantable medical device also comprising a second frame component including a second set of elongate elements configured to conform to an anatomy of a patient. The first frame component and the second frame component being discrete and separate from one another. The implantable medical device also comprising a conduit portion arranged between the first frame component and the second frame component. The conduit portion including a membrane connecting the first frame component and the second frame component.

An implantable device comprising a main endoprosthesis configured for implantation in a vessel, the main endoprosthesis including at least one side portal, a first side-branch endoprosthesis configured to be deployed within the main endoprosthesis and direct flow through a first side-branch vessel via the at least one side portal, a second side-branch endoprosthesis configured to be deployed within the main endoprosthesis and direct flow through a second branch vessel via the at least one side portal, and wherein when not containing a side-branch endoprosthesis the at least one side portal comprises a side channel without fluid separation.

Various aspects of the present disclosure are directed toward apparatuses, systems, and methods that include device for chordae tendineae repair. The device may include a flexible cord having a first end and a second end; and a helical wire configured to attach to one of the first end and the second end of the flexible cord and anchor the flexible cord to a leaflet of a heart valve; and a capture device having a channel and configured to clamp the leaflet of the heart valve and deliver the flexible cord through the channel to anchor the helical wire to the leaflet.

A catalytic composite is formed of a catalytic layered assembly including a porous catalytic fluoropolymer film and one or more felt batts connected with the porous catalytic fluoropolymer film. At least one felt batt is positioned adjacent the upstream side of the porous catalytic fluoropolymer film to form the catalytic composite. The fluoropolymer film is perforated to allow for enhanced airflow therethrough while retaining the capability of catalyzing the reduction or removal of chemical species in fluid flowing through the catalytic composite.
