[57] ABSTRACT

A spring-loaded reciprocable stylet holder assembly includes a cap; a hollow body element partially nested within and reciprocable a major part of its length into the cap; a spring urging the body element outwardly of the cap; and a stylet supported at one end by the cap and extending through and beyond the body element. The remote end of the body element has a small borehole through which the stylet extends. The remote end is also provided with attachment means for a hypodermic needle with slotted tip for T-fastener emplacement, the needle telescopically surrounding the full length of the stylet. In a useful modification of the device an insufflation adapter having a side port for attachment of a hypodermic syringe is placed in line between the body element and the hypodermic needle. The stylet holder assembly with a slotted hypodermic needle attached thereto may be used for emplacing a T-fastener in a hollow organ of a person, such as the stomach.
