Disclosed herein are vascular access systems and methods thereof. For example, a vascular access system includes a port configured for subdermal implantation and a single-use access device. The port can include a port hub and a catheter tube. The port hub can include an access funnel and a septum defining a pair of port-hub lumens. The catheter tube can include a septum defining a pair of catheter-tube lumens fluidly coupled to the pair of port-hub lumens. The access device can include a bifurcated hub and a pair of cannulas. The pair of cannulas defines a pair of cannula lumens coupled to a pair of access device-hub lumens of the bifurcated hub. The pair of cannulas can be configured to simultaneously insert into the access funnel and couple the pair of cannula lumens to the pair of catheter-tube lumens when the pair of cannulas is fully seated in the port hub.

A medical device and method to deliver a liquid solution to a patient's tissue. In particular a medical device that is an infusion device comprising a plurality of delivery tubes with varying lengths and internal diameters so that when the selected plurality of delivery tubes are implanted there is equal impedance to flow through each of the attached delivery tubes resulting in equal flow out of the delivery tubes to regions of interest in the patient's tissue. The plurality of delivery tubes may be attached to an infusion hub in a regular symmetrical pattern or an irregular asymmetrical pattern as required to deliver liquid solution to a plurality of regions of interest in the patient's tissue.

A fluid distribution system for delivering fluid internally of a body comprises a hollow needle and an implantable access port. The needle has a tip with a predetermined shape. The access port includes (a) a housing that includes at least two fluid outlets, (b) a septum received in the housing, and (c) a valve member rotatable in the housing. The valve member includes valve fluid inlet and outlet openings and a valve inlet passage extending from the inlet opening to the outlet opening. The valve inlet passage has a shape complementary to the shape of the needle tip. The valve member is rotatable into (i) a first position in which the valve fluid outlet opening communicates with a first housing fluid outlet and (ii) a second position in which the valve fluid outlet opening communicates with a second housing fluid outlet.

Described herein are implantable ports including a housing with a fluid receptacle, a port stem in fluid communication with the fluid receptacle, and a septum covering the fluid receptacle. The ports may be configured to reduce the priming volume by including a plurality of fluid-locked chambers and/or one or more base mats. The ports may also include a hydrophobic coating on one or more surfaces thereof.

A method of making an access port, includes providing a port body defining a fluid cavity, positioning a septum over the fluid cavity, and securing the septum to the port body. The septum includes a lower portion having a first diameter, an upper portion joined to the lower portion at a juncture, the upper portion having a second diameter less than the first diameter at the juncture, and a plurality of palpation features joined to the upper portion. Each of the palpation features includes a first end adjacent a central axis of the septum, and a second end extending radially outward, overlapping the juncture.

Fluid delivery systems and methods of delivering a therapeutic agent are disclosed that include a subcutaneously implantable port that can be easily and efficiently located through the tissue of a patient. The port includes a body that defines a chamber having an open top, a delivery opening, and a catheter connection portion, and a septum disposed on the body, where the septum includes a lower surface extending over the open top of the chamber and an opposite, upper surface. The port further includes a cap of the port that defines an opening extending therethrough and the cap is configured to be coupled to the body to secure the septum within the port with the opening of the cap providing needle access to the septum. The cap includes a downwardly tapered surface that extends around the opening and is configured to direct a needle towards the upper surface of the septum.
