Abstract: Systems and methods for delivering multiple embolization coils to a location within the body of a patient are disclosed. In one embodiment, a coil delivery system has coil deployment members coupled to embolization coils and is arranged for independent movement of the embolization coils. In some exemplary embodiments, the disclosure provides coil delivery systems in which the embolization coils are positioned within different lumens and/or on different straightening members. Methods and other embodiments are disclosed.

Abstract: A delivery device for delivering material into a catheter through a catheter port includes a cannula having a generally tubular shape and a distal end and a stability collet having a distal attachment portion configured to attach the stability collet to a catheter port. The stability collet has a longitudinal channel through which the cannula extends. The longitudinal channel is dimensioned to allow a longitudinal movement of the cannula in the longitudinal channel. The delivery device further includes an elastic member acting between the cannula and the stability collet. The elastic member biases the cannula distally relative to the stability collet. Thus, when the stability collet is attached to the catheter port, the cannula is urged toward the catheter port, thus reducing a risk of improper alignment between the cannula and the catheter port.

Abstract: A reperfusion system and method of perfusing a blood vessel using the reperfusion system are provided. A sheath has a sheath wall and a lumen that each extend to a distal end to define a distal opening. A distal portion of the sheath wall has at least one wall opening. A balloon catheter has a lumen that extends to the distal end to define a distal opening. The balloon catheter has an inflatable balloon attached to a distal portion. A conduit has a first end in fluid communication with the lumen of the sheath and a second end in fluid communication with the lumen of the balloon catheter. The reperfusion system is configured to allow blood to enter each of the distal opening and the at least one wall opening of the sheath, flow through the sheath, the conduit, and the balloon catheter, and exit through the distal opening of the balloon catheter. The sheath is introduced into body tissue. The balloon catheter is advanced through the sheath to the blood vessel. The balloon is inflated.
