EXTENSIBLE INTERNAL BOLSTER FOR A MEDICAL DEVICE
First Claim
1. An internal bolster for securing a medical device within a body of a patient, the internal bolster comprising:
- at least one bolster arm including a first end hingedly connected to a distal end of the medical device and a free second end,wherein the at least one bolster arm is selectively deployable between a first position wherein the at least one bolster arm is substantially in-line with an axis of the medical device and a second position wherein the at least one bolster arm is substantially deflected from the axis of the medical device to enable securement of the medical device within the body.

Abstract
An internal bolster for use securing a medical device, such as a feeding tube, within a body of a patient is disclosed. In one embodiment, a feeding tube includes an internal bolster, comprising one or more bolster arms that each include a first end hingedly connected to a distal end of the medical device and a free second end. The bolster arms are selectively deployable between a first position wherein the bolster arms are substantially in-line with an axis of feeding tube, and a second position wherein the bolster arms are substantially deflected from the axis of the feeding tube to enable securement of the feeding tube within a stoma or other opening defined in the body. Various means for selectively moving the bolster arms between the first and second positions are disclosed. Related methods of use are also disclosed.

19. A method for inserting a medical device into a body of a patient, comprising:
-
inserting a distal portion of the medical device into the body, the distal portion including an internal bolster, the internal bolster including at least one bolster arm hingedly connected at a first end to the distal portion of the medical device and including a free second end, the at least one bolster arm being in a first position during insertion wherein the at least one bolster arm is substantially parallel with a longitudinal axis of the medical device; and radially deploying the at least one bolster arm to a second position wherein the at least one bolster arm is positioned substantially non-parallel with respect to the longitudinal axis of the medical device to secure the distal portion of the medical device within the body. - View Dependent Claims (20, 21)

22. A feeding device, comprising
an elongate body defining a cavity and including a distal portion for insertion into a body of a patient; -
a plunger movably disposed within the cavity of the elongate body; and an internal bolster including; at least one foldable flap including a proximal end attached to a distal portion of the plunger; and at least one tether connecting the distal portion of the elongate body with a distal end of the at least one foldable flap, wherein movement of the plunger within the cavity of the elongate body causes folding of the flap from a first unfolded position to a second folded position so as to enable the internal bolster to secure the distal portion of the feeding device within the body of the patient.
