1. A device operable for injecting a fluid medium from a source of said fluid medium having a fluid output port into an interface
between a handgrip and a tubular member, wherein the handgrip comprises an elongate, substantially cylindrical member comprised
of an elastomeric material and having a cylindrical recess in an open end thereof, said cylindrical recess defining a cavity,
said device comprising:
(a) a handle portion adapted to be grasped by a hand, said handle portion having a proximal end adapted to sealingly engage
said fluid outlet port of said source of said fluid medium, a distal end and a first fluid-conducting conduit defining a first
axis therebetween;
(b) an insertion tip having a proximal end affixed to and sealingly engaging said distal end of said handle portion, a distal
end having an opening therein and a second fluid-conducting conduit in fluid communication with said first fluid-conducting
conduit and said opening, said second fluid conducting conduit defining a second axis that is angled at about 90° with respect
to to said first axis, and wherein said distal end of said insertion tip has a crescent-shaped transverse cross-section.
