Title:
METHOD AND APPARATUS FOR PROVIDING MEDICAMENT TO TISSUE
Document Type and Number:
WIPO Patent Application WO2003037203
Kind Code:
A3
Abstract:
A system for delivering medicaments to tissue includes a tissue-removal and medicament-delivery device. The device includes a delivery member and an optical fiber formed together into a unitary structure by cladding. The optical fiber has an inlet for receiving laser energy from a laser energy source and an outlet for emitting laser energy. The delivery member has an inlet for receiving medicament from a medicament source and an outlet for injecting medicament. A handpiece is adapted to receive the ablating and injecting device in a controlled and movable relationship. The distal end of the handpiece disposes at least one tissue stabilizing member thereon. The medicament delivery system is particulary useful in cardiac applications for performing transmyocardial revascularization (TMR) in ischemic myocardium and promoting endothelial cell growth within the myocardium.
