and lower pair of movable arms 296 of compression clip 292 fig1 shows a schematic side cross sectional view of adaptor 300 illustrating the location of compression clips 290 and 292 positioned within recess 294 and about gastrostomy tube 10 and stem 301 fig1 shows a perspective view of a feeding tube assembly 306 including a coupler 304 with a radially protruding feature 302 and a stem portion 305 and feeding tube 309 extending from the stem portion 305 coupler 304 may be configured for mechanically coupling to a connector 312 e g connector 90 as discussed above or a base element as discussed below more particularly protruding feature 302 may align with groove 310 formed in recess 307 of the connector 312 further protruding feature 302 may fit into or otherwise engage a lip or other feature e g another recess such as recess 134 as shown in fig4 formed into the surface of recess 307 another aspect of the instant disclosure relates to a gastrostomy tube adaptor that has a clamping mechanism that may be installed upon a base element including a stem more particularly a clamping mechanism may be configured to at least partially circumferentially contact and correspondingly radially compress a gastrostomy tube onto a stem of the base element for example a clamping mechanism may include two separate pieces that couple to one another to compress a gastrostomy tube onto a stem of the base element more generally a system for providing fluid communication with a gastrostomy tube may include a plurality of separate pieces which when assembled are configured to compress at least a portion of an end region of a gastrostomy tube.
