1. A feeding tube assembly comprising:

  • a flexible tube section having proximal and distal ends and a bore extending therethrough, said tube section having a predetermined inner diameter and length for the selective administration and aspiration of fluids from the gastrointestinal tract of a patient,a hollow connector member operatively connected to said proximal end of said tube section, said connector member including a bore therein in communication with said bore of said tube section,a semi-rigid bolus tube section including a proximal end operatively connected to said distal end of said tube section, a closed distal end extending distally from said proximal end and a bore extending through said proximal end of said bolus tube section in communication with a plurality of side holes and said bore terminating in an end wall located proximal to the distal end of said bolus tube section and wherein said bolus tube section is less flexible than said tube section,a stylet hub member, adapted to be removably retained in said connector member,an elongate and semi-rigid wire having proximal and distal ends and an outer diameter smaller than the diameter of said bore of said tube section, said proximal end of said wire being operatively connected to said hub member and said wire having a predetermined length such that when said hub member is inserted into said connector member, said distal end of said wire is positioned near said proximal end of said bolus tube section, anda flexible and elongate stylet tip member having a first and a second section wherein said tip member has a substantially uniform outer diameter which is less than the inner diameter of said bore of said bolus tube section, said outer diameter of said tip member being preferably between 1 and 2 mm and said outer diameter of said tip member being smaller than the smallest diameter of said side holes in said bolus tube and wherein said first section of said tip member is operatively connected to said distal end of said wire and said second section extends distally from said distal end of said wire to form a hollow and deformable stylet tip extending from the distal end of said wire.
