Gastric jejunal feeding tube devices for gastric jejunal feeding of an infant or child

A gastric jejunal (GJ) feeding tube device for GJ feeding of an infant or child, comprising:

• (a) a GJ button comprising (i) a GJ button body, (ii) a gastric port, (iii) a jejunal port, (iv) a gastric channel, and (v) a jejunal channel, the GJ button body having a proximal surface, a distal surface, and a base opening, the gastric port and the jejunal port being positioned at the proximal surface, the base opening being positioned at the distal surface, the gastric channel and the jejunal channel extending from the gastric port and the jejunal port, respectively, to the base opening, and the jejunal channel having a mating surface therein;
• (b) a multi-lumen tube comprising (i) a multi-lumen tube body, (ii) a multi-lumen tube proximal end, and (iii) a multi-lumen tube distal end, the multi-lumen tube body defining a gastric lumen and a jejunal lumen, the gastric lumen and the jejunal lumen each having a proximal opening located at the multi-lumen tube proximal end and a distal opening located along the multi-lumen tube body or at the multi-lumen tube distal end;
• and
• (c) a jejunal tube comprising (i) a jejunal tube body, (ii) a jejunal tube proximal end, (iii) a jejunal tube distal end, (iv) a spring, and (v) a ring, the jejunal tube body defining a jejunal tube passage having a proximal opening located at the jejunal tube proximal end and a distal opening located at the jejunal tube distal end, the spring being positioned within the jejunal tube body, extending therealong, and providing a kink-resistant feature thereto, and the ring being positioned at the jejunal tube proximal end, coaxially with respect to the jejunal tube body, wherein:
• the jejunal tube and the GJ button are operatively connected at the ring and the mating surface, the mating surface radially compressing the ring;
• the multi-lumen tube and the GJ button are operatively connected at the multi-lumen tube proximal end and the base opening;
• the jejunal tube extends through the jejunal lumen of the multi-lumen tube;
• the ring has a higher durometer than the jejunal tube body;
• and
• the ring has an outer diameter that does not substantially decrease distally with respect to the jejunal tube.
