Direct Fluid Path for Inline Dual Lumen Port
Embodiments disclosed herein are directed to a dual, in-line port having a direct fluid path between the proximal reservoir and the stem. The port includes a conduit extending through the distal reservoir and defining a lumen in fluid communication with the proximal reservoir and the stem. The axis of the conduit lumen is aligned with stem lumen to minimize any tortuous fluid pathway and reduce fluid flow resistance. The port can further include a needle guard extending over the distal reservoir and configured to prevent an access needle from impinging on the conduit when accessing the distal reservoir. Embodiments can further include a removable reservoir insert that defines the distal reservoir.
Therapeutic agent injection device
A therapeutic agent injection device including an injection device for delivering a therapeutic agent to a patient having a body, the body having a patient face and a port face opposite the patient face, the port face having an introducer port including an introducer channel and an injection port including an injection channel, the introducer channel being in fluid communication with the injection channel through a cross channel, the injection channel defining an injection axis; a delivery tube for subcutaneous delivery of the therapeutic agent to the patient, the delivery tube projecting from and being generally perpendicular to the patient face, the delivery tube defining an introducer axis and being in fluid communication with the injection port; and a patch, the patch being attached to the patient face and being operable to adhesively attach to the patient; wherein the injection axis is parallel to the introducer axis.
Implantable infusion devices and associated methods
Implantable infusion devices configured to improve fill and evacuation procedures.
Methods for implanting subcutaneous vascular access ports
A method of securing an access port to a vessel can include positioning an access port adjacent to a wall of the vessel. The access port can include an implantation passageway and a guidance passageway that is connected to the implantation passageway. The implantation passageway can be open, during the positioning of the access port, at a position proximal to a location at which the implantation passageway and the guidance passageway are connected. The method can further include forming an opening in the wall of the vessel via instruments that extend through the implantation passageway. The method can include securing the access port to the vessel such that the implantation passageway is in fluid communication with an interior of the vessel via the opening in the wall of the vessel. The method can also include sealing the implantation passageway at the position proximal to the guidance passageway.
Variable length portal access device
A portal access device has a first member pivotally movable relative to a base. A groove is provided at the first member to be in alignment with a bore at the base, so that a cannula may freely extend through the bore, with a portion of the cannula being frictionally held along the groove of the first member. The first member may be rotatably connected to a second member, so that once the cannula is correctly inserted into a portal, the first member may be pivoted from its vertical position to its horizontal position to bend the cannula into a right angle cannula. The cannula is removed from the portal by pivoting the second member upwardly away from the base. In an alternate portal access device where there is only one arm member, the portal access device may be removed from the portal by being pulled vertically upwards.
Implantable dual reservoir access port
A dual reservoir access port includes a base having proximal and distal fluid reservoirs. The fluid reservoirs each comprise a bottom and a side wall. A dual prong outlet stem projects from a distal end of the base and comprises a first prong and a second prong. A first fluid channel extends through the first prong to the distal reservoir, and a second fluid channel extends through the second prong to the proximal fluid reservoir. A puncture shield is disposed between at least a portion of the second fluid channel and the bottom of the distal fluid reservoir. A needle-penetrable septum is disposed atop of each of the fluid reservoirs. A cap is placed over and around the port base compressing and sealing the septa against the base. A locking collar may be placed over a dual lumen catheter to lock the catheter to the dual prong outlet stem.

MEDICAL ACCESS PORT, SYSTEMS AND METHODS OF USE THEREOF
A medical device comprising a subcutaneous access port having an access port body and at least one needle having a removable needle tip and a needle shaft defining a needle lumen; the at least one needle housed within the access port body, the at least one needle extendable and retractable relative to the access port body; and a needle shift mechanism operable such that the at least one needle is extendable from and retractable into the access port body at a plurality of positions of the access port body.
VENOUS ACCESS PORT ASSEMBY WITH X-RAY DISCERNABLE INDICIA
A venous access port assembly (10) having a housing base (22) with a discharge stem (16), a septum (14), a cap (20) and an interior reservoir (26). The port assembly (10) is provided with X-ray discernable indicia (60,62) to identify an attribute of the assembly (10) after its implantation and clearly appear on an X-ray of the patient in a manner informing the radiologist or technologist and the medical practitioner of that particular attribute. The indicia are cutouts (60,62) through a reservoir lining (50) of radiopaque material such as metal where the cutouts have narrow slot width are in the form of one or more sets of alphabetical letters such as CT in the lining's side wall (52) or bottom wall (54).
