and catheter embodiments in a manner similar to those embodiments once the instrument is positioned in a desired position the bonding agent is injected into a lumen of the instrument or alternatively in a manner like that described supra released from a container or chamber in the distal end of the instrument so that it may be infused from one or more infusion ports 88 disposed on the distal end of the instrument preferably the ports 88 are disposed on a bushing or sleeve 90 which has a linear slot 92 for permitting passage of the cutting element 86 as it is extended and retracted radially and which is rotatable relative to the shaft 84 thus when the bonding agent is infused to the surrounding tissue so that the bushing 90 is affixed in place relative to the surrounding tissue the cutting element 86 will still be rotatable on the underlying shaft 84 in order to permit circumferential cutting of tissue as desired during the later procedural step suitable care is taken that only a sufficient amount of bonding agent is dispensed to bond the bushing to surrounding tissue and not the shaft or tip of the instrument in order that the shaft and tip continue to be rotatable relative to the bushing of course the bushing 90.
