Abstract:
A system for accessing and anchoring a desired portion of tissue within a patient, comprising:a) a tissue accessing device having an elongated cannula with a proximal end, a port in the proximal end, a distal end and a port in the distal end, and an inner lumen in fluid communication with the ports in the proximal and distal ends; and b) an anchoring device configured to be slidably disposed within the inner lumen of the cannula, having i. an elongated shaft having a proximal end and a distal end, ii. at least one opening on the distal end configured to guide an extension wire in a radial direction away from the distal end, iii. at least one extension wire within the elongated shaft which has a free end, which has a withdrawn configuration within the elongated shaft, which has a deployed configuration when extended through the opening in the distal end so the free end of the extension wire extends for a distance radially away from the distal end of the shaft, and iv. a deployment actuator which is configured to deploy the extension wire from the withdrawn configuration to the deployed configuration.
