Abstract
A biological agent delivery device for delivering biological agents includes a sheath having a longitudinally extending wall surrounding an interior region, and a closed tip at a distal end. A flexible pouch formed in the sheath wall for containing a biological agent is capable of being displaced radially outwardly for radially displacing the biological agent.
Claims30
A biological agent delivery device comprising:
- a sheath having a longitudinally extending wall surrounding an interior region, and a closed tip at a distal end;
- and
- a flexible circumferential pouch system formed in the sheath wall and encircling the sheath including at least one annular pouch, the pouch system having a closed position and a open position, the closed position for containing a biological agent in a circular manner about the sheath and the open position for displacing the biological agent outwardly in a circular manner.
A biological agent delivery catheter comprising:
- a flexible sheath having a longitudinally extending wall surrounding an interior region, and a closed tip at a distal end;
- a radially facing flexible circumferential pouch system formed in the sheath wall and encircling the sheath including at least one annular pouch, the pouch system having a closed position and a open position, the closed position for containing a biological agent in a circular manner about the sheath and the open position for displacing the biological agent outwardly in a circular manner;
- a guide wire extending within the sheath for guiding the catheter;
- and
- a displacement member disposed within the sheath for causing the pouch to be displaced to the open position to deliver the biological agent outwardly in a circular manner.

A method of forming a biological agent delivery device comprising the steps of:
- providing a sheath having a longitudinally extending wall surrounding an interior region, and a closed tip at a distal end;
- providing the sheath with a flexible circumferential pouch system including at least one annular pouch for containing a biological agent formed in the sheath wall in a circular manner capable of being displaced radially outwardly circumferentially for radially displacing the biological agent.
A method of delivering a biological agent to a tissue site comprising the steps of:
- providing a sheath having a longitudinally extending wall surrounding an interior region, and a closed tip at a distal end;
- containing a biological agent within a flexible circumferential pouch system formed in the sheath wall encircling the sheath including at least one annular pouch, the pouch system having a closed position and a open position, the closed position for containing a biological agent in a circular manner about the sheath and the open position for displacing the biological agent outwardly in a circular manner;
- inserting the sheath into the tissue site;
- and
- radially displacing the pouch outwardly to the open position with a displacement member disposed within the sheath to deliver the biological agent outwardly in a circular manner to the tissue site.
