1. A device for delivering a substance to an internal portion of a body which has been acted on by a removable procedure performing instrument, said device comprising:
- an application tube having a proximal end, a distal end and an internal lumen for receiving said substance and at least a portion of said instrument, said internal lumen distally terminating at a single opening located at the distal tip of said application tube;
a housing assembly disposed on the proximal end of said application tube and having a lumen extending from a proximal end of said housing assembly to a distal end of said housing assembly, said housing lumen being in communication with the internal lumen of said application tube so as to define a flow passage and through which said procedure performing instrument is slidingly moveable; and
a flow control member disposed in said flow passage and having a portion that has a first position that opens said flow passage and a second position that closes said flow passage.

13. A device for obtaining a tissue sample from a body site and for applying at least one substance to said site said device comprising
a biopsy cannula having an internal lumen and a distal cutting edge for cutting off tissue; -
a needle member slidably mounted within said lumen and having a recess for receiving said tissue sample;
a driver associated with said cannula and said needle for effecting relative movement between said cannula and said needle and cutting of said tissue;
an application tube having a proximal end, a distal end and an internal lumen said application tube being disposed around said cannula, the distal end of said application tube being rearwardly offset relative to the cutting edge of said cannula;
a housing assembly sealingly engaging the proximal end of said application tube, said housing assembly including an internal lumen through which said cannula and said needle are slidingly moveable, said housing lumen being in communication with the internal lumen of said application tube so as to define a flow passage; and
a flow control member disposed in said flow passage and having a portion that has a first position that opens said flow passage and a second position that closes said flow passage. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
