Patent ID: 6840952

Claim:
A tissue tract sealing device for use with a medical cannula to seal a tissue tract made in a living tissue by the medical cannula with a flowable biocompatible material, the tissue tract sealing device comprising: an elongated housing having a coupling on a distal end adapted to fluidly couple the device to the medical cannula; a reservoir within the housing that contains the flowable biocompatible material; a piston arrangement within the housing and in fluid connection with the reservoir that discharges the flowable biocompatible material from the reservoir to the coupling; and a cannula rector operably engaged in at least one longitudinal channel defined along at least a portion of the elongated housing, the cannula retractor operably connected to the coupling and the piston arrangement such that sliding of the cannula retractor along the channel causes the cannula to withdraw from the tissue tract and causes the piston arrangement to discharge the flowable biocompatible material into the tissue tract.
