## Abstract

A low-profile access port for subcutaneous implantation within a patient is disclosed. The access port includes a receiving cup that provides a relatively large subcutaneous target to enable catheter-bearing needle access to the port without difficulty. In one embodiment, a low-profile access port comprises a body including a conduit with an inlet port at a proximal end, and a receiving cup. The receiving cup is funnel shaped to direct a catheter-bearing needle into the conduit via the inlet port. The conduit is defined by the body and extends from the inlet port to an outlet defined by a stem. A bend in the conduit enables catheter advancement past the bend while preventing needle advancement. A valve/seal assembly is also disposed in the conduit and enables passage of the catheter therethrough while preventing fluid backflow. The body includes radiopaque indicia configured to enable identification of the access port via x-ray imaging.

## Claims

### Claim 1

A low-profile access port, comprising:
a first receiving body portion formed from a metal material, the first receiving body portion comprising:
a first receiving cup including a first inlet port;
a first conduit in communication with the first inlet port; and
a depression or recess forming an alphanumeric designation;
a second receiving body portion formed from a metal material, the second receiving body portion comprising:
a second receiving cup including a second inlet port; and
a second conduit in communication with the second inlet port;
an outlet body portion in fluid communication with the first receiving body portion and the second receiving body portion, the outlet body portion comprising:
a bifurcated proximal end having a first connection portion coupled to the first receiving body portion and a second connection portion coupled to the second receiving body portion; and
a stem having a first fluid outlet in fluid communication with the first connection portion and a second fluid outlet in fluid communication with the second connection portion;
a first valve assembly between the first connection portion and the first receiving body portion;
a second valve assembly between the second connection portion and the second receiving body portion; and
an overmolded portion surrounding at least the first receiving body portion and the second receiving body portion.

### Claim 2 (depends on 1)

The access port according to claim 1, wherein the first valve assembly and the second valve assembly each includes a seal defining a central hole and a valve including one or more slits.

### Claim 3 (depends on 1)

The access port according to claim 1, wherein the first receiving cup is configured to direct a catheter-bearing needle into the first inlet port, and wherein the second receiving cup is configured to direct the catheter bearing needle into the second inlet port.

### Claim 4 (depends on 1)

The access port according to claim 1, wherein the alphanumeric designation is located in the first receiving cup.

### Claim 5 (depends on 1)

The access port according to claim 1, wherein the second receiving body portion includes a depression or recess forming an alphanumeric designation.

### Claim 6 (depends on 5)

The access port according to claim 5, wherein the alphanumeric designation is located in the second receiving cup.

### Claim 7 (depends on 1)

The access port according to claim 1, wherein the first receiving body portion and the second receiving body portion are angularly positioned on opposite sides of a central longitudinal axis of the access port.

### Claim 8 (depends on 7)

The access port according to claim 7, wherein the central longitudinal axis of the access port bisects the first fluid outlet and the second fluid outlet of the stem.

### Claim 9 (depends on 1)

The access port according to claim 1, wherein the alphanumeric designation includes the letters “IV”.

### Claim 10 (depends on 1)

The access port according to claim 1, wherein a perimeter of the first receiving cup and a perimeter of the second receiving cup are disposed in a single imaginary plane.

### Claim 11 (depends on 1)

The access port according to claim 1, wherein the first conduit and the second conduit each defines a conduit bend to prevent passage of a needle of a catheter-bearing needle while permitting passage of a catheter of the catheter-bearing needle.

### Claim 12 (depends on 11)

The access port according to claim 11, wherein the first valve assembly and the second valve assembly are disposed distal to the conduit bend of the first conduit and the second conduit.

### Claim 13 (depends on 1)

The access port according to claim 1, further comprising at least one palpation feature configured to enable a clinician to palpate a location of the access port following subcutaneously implantation.
