Biased Internal Bolster for a Medical Device

An internal bolster for anchoring a medical device in a percutaneous stoma in a body of a patient, the internal bolster comprising:

• a plurality of resilient, looped arms disposed at a distal end of the medical device, each arm extending radially outward from the medical device so as to prevent the medical device from being inadvertently removed from the stoma, each arm including at least one reinforcing rib extending longitudinally along the arm.

A feeding catheter for providing fluid access to a stomach of a patient via a percutaneous stoma, the feeding catheter comprising:

• an elongate inner tube defining at least one lumen and coaxially and disposed within an outer tube, the inner tube slidable with respect to the outer tube;
• and
• an internal bolster comprising a plurality of hinged arms, a proximal end of each arm attached to a distal portion of the outer tube, a distal end of each arm attached to a distal portion of the inner tube, wherein proximal movement of the inner tube with respect to the outer tube causes the arms of the internal bolster to fold into an radially extended configuration so as to prevent inadvertent removal of the catheter from the stoma.
