Percutaneous obturatable internal anchoring device
First Claim
1. A device designed to pass through an opening in the wall of the abdomen and stomach or other viscera of a patient and to be selectively operated between a relaxed retaining position and a flexed elongated position for insertion into and removal from said patient, said device comprising:
- a hollow tubular member having an inner end and an outer end and a longitudinal passage extending therethrough;
an anchoring device joined to said outer end, said anchoring device having a discontinuous flexible body with a silhouette approximating a truncated pyramid in the relaxed position, the base of said pyramid attached to said tubular member and the truncated apex of said pyramid having a guidance passage aligned with said longitudinal passage for directing a linear elongated body being advanced through said tubular member into said patient; and
means for facilitating deformation of said flexible body from said relaxed position to said flexed elongated position formed interiorly of said truncated pyramid.

Abstract
An internal anchoring device to which a tubular member is attached for introduction/removal of fluids/gases into and out of viscera of a patient. The internal anchoring device is a discontinuous flexible body having a silhouette approximating a truncated pyramid when in a relaxed position. The internal anchoring device provides increased anchoring capability over devices of the prior art yet, at the same time, is easily obturated, thereby facilitating placement/removal.
