## Abstract

The feeding tube system includes an elongated shaft having a proximal portion, an opposing distal portion, and a central opening or lumen extending therethrough. The proximal portion is configured to remain outside a patient's body cavity and includes a first opening through which fluids can be introduced into the lumen. The distal portion is configured for disposing within a patient's body cavity and includes a second opening for discharging fluids from the lumen into the patient's body cavity. An interior retention balloon is provided at the distal portion of the elongated shaft. An external base positioned at the proximal portion of the feeding tube can include at least one exterior base balloon extending therefrom. The interior retention balloon and the at least one exterior base balloon are inflatable.

## Claims

### Claim 1

A feeding tube system, comprising:
an elongated shaft having a proximal portion, a distal portion, and a central lumen extending therethrough, the proximal portion including a first opening for receiving fluids and the distal portion including a soft tip having a second opening, the second opening configured for discharging the fluids into a patient's body cavity, wherein the first and second openings are aligned and continuous with the central lumen, further wherein the elongated shaft includes a check valve at the proximal portion;
an inflatable interior retention balloon in communication with the distal portion of the elongated shaft; and
an external base coupled to the proximal portion of the elongated shaft, the external base including:
i) an upper horizontal support,
ii) a lower horizontal support,
iii) a pair of separate exterior base balloons disposed beneath and attached to the lower horizontal support, wherein each of the base balloons has a first deflated size and a second inflated size, the inflated size being larger than the deflated size, and
iv) a first inflation port and a second inflation port, the first inflation port and the second inflation port being disposed between the upper horizontal support and the lower horizontal support and each of the inflation ports including a releasable one-way valve, wherein the first inflation port is in sole fluidic communication with the internal retention balloon and wherein the second inflation port is in sole fluidic communication with the pair of separate exterior base balloons, further wherein the base balloons are capable of being inflated to a size extending beyond the first and second inflation ports.

### Claim 2 (depends on 1)

The feeding tube system according to claim 1, wherein the lower horizontal support comprises a circular base plate.
