Abstract: An esophageal stent including a stent body having a proximal portion and a distal portion. The proximal portion includes an anchoring structure. The stent also includes a valve attached to the distal portion of the stent.

Abstract: Although injection molding includes extreme conditions, an RFID device may be over-molded by injection molding. A syringe includes a barrel having a first and second axial ends, the barrel defining a cavity therein; a plunger configured to be received in the cavity and define with the barrel a chamber for holding a fluid, the plunger being axially moveable within the barrel for increasing and decreasing the volume of the chamber thereby respectively forcing fluid into or out of the chamber; and a plunger seal, also known as a “syringe stopper” for sealing between the plunger and the barrel, the plunger seal including an RFID device for identifying the syringe. The plunger seal may be made by injection molding.

Abstract: A fluid connection device includes a first connector having at least one fluid passage and a second connector having at least one fluid passage. The second connector includes a sealing door that may be opened and closed for sealing the fluid passage when the first connector and the second connector are disconnected. The first connector includes a mechanical or electronic key for actuating the second connector, such that the sealing door opens in response to the key. When the sealing door is opened, the first connector may be joined with the second connector. When the first connector is fully joined with the second connector, the fluid passages may be adjacently aligned and in fluid communication for fluid flow therebetween.

Abstract: A radio frequency identification (RFID)-enabled article includes a body formed of a plastic or other polymeric first material having at least one wall, the wall having a length, a width, and a thickness, and wherein the thickness dimension is smaller than the length and the width and is defined between a first surface and a second surface; and an RFID transponder embedded 5-95% into the thickness dimension of the wall. The first and second surfaces of the wall are free from witness marks.
