Tissue tract sealing device
First Claim
1. 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:
- at least two reservoirs, at least one of the reservoirs for containing the flowable biocompatible material;
means for discharging the flowable biocompatible material from the reservoirs in a controlled manner through the cannula; and
means operably connected to the means for discharging for withdrawing the cannula from the tissue tract in a controlled manner such that operation of the means for withdrawing causes the means for discharging to discharge the flowable biocompatible material into the tissue tract thereby substantially filling at least a longitudinal portion of the tissue tract with the flowable biocompatible material.

Abstract
A device and system for delivery of a flowable biocompatible material to a tissue tract in a controlled manner generally includes reservoirs adapted to be in fluid connection with a cannula, a discharging mechanism adapted to discharge the contents of the reservoirs and a cannula retractor to withdraw the cannula. The cannula retractor is operably interconnected with the discharging mechanism so that a measured quantity of the reservoirs contents is smoothly discharged to substantially fill at least a portion of the tissue tract.

16. A method of sealing a tissue tract left behind by the medical insertion and removal of a tube-like member, the method comprising:
-
filling at least one of at least two reservoirs with flowable biocompatible materials;
interconnecting the reservoirs with a cannula and with means for discharging the flowable biocompatible material from the reservoir in a controlled manner through the cannula;
withdrawing the cannula while at the same time the means for discharging discharges the flowable biocompatible material so as to substantially fill at least a portion of the tissue tract.

19. 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:
-
at least two independent reservoirs for containing the flowable biocompatible materials;
at least one piston that discharges the flowable biocompatible material from each of a corresponding one of the two reservoirs in a controlled manner through the cannula; and
a withdrawal actuator operably connected to the piston that withdraws the cannula from the tissue tract in a controlled manner such that operation of the withdrawal actuator causes the at least one piston to discharge the flowable biocompatible material into the tissue tract thereby substantially filling at least a longitudinal portion of the tissue tract with the flowable biocompatible material.

30. 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:
-
at least two flexible reservoirs that contains the flowable biocompatible material;
a compression mechanism operably connected to the flexible reservoirs that discharges the flowable biocompatible material from the reservoirs in a controlled manner through the cannula; and
a cannula retractor operably connected to the compression mechanism that withdraws the cannula from the tissue tract in a controlled manner such that operation of the cannula retractor causes the compression mechanism to compress the flexible reservoirs so as to discharge the flowable biocompatible material into the tissue tract thereby substantially filling at least a longitudinal portion of the tissue tract with the flowable biocompatible material. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 40, 41, 42, 43, 44, 46, 47, 48, 49, 50)

39. A kit for sealing a tissue tract comprising:
-
a tube-like mechanism adapted for insertion into and withdrawal from living tissue;
at least two reservoirs adapted to hold a quantity of a flowable biocompatible material;
a discharge mechanism operably connectable between the tube-like mechanism and the reservoirs to discharge the flowable biocompatible material in a controlled manner into a tissue tract created by insertion of the tube-like mechanism in response to withdrawal of the tube-like mechanism so as to substantially fill at least a longitudinal portion of the tissue tract.

45. 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;
at least two reservoirs within the housing at least one of the two reservoirs containing at least a portion of the flowable biocompatible material;
at least one piston arrangement within the housing in fluid connection with the reservoirs that discharge the flowable biocompatible material from the reservoirs to the coupling; and
a cannula retractor 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.

51. 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:
-
at least two reservoirs within the housing the at least two reservoirs each containing at least a portion of the flowable biocompatible materials;
an elongated housing having a coupling on a distal end adapted to fluidly couple the device to the medical cannula such that the at least two reservoirs both discharge into the medical cannula;
at least one piston arrangement within the housing in fluid connection with the reservoirs that discharge the flowable biocompatible material from the reservoirs to the coupling; and
a cannula retractor 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. - View Dependent Claims (52, 53, 54, 55, 56, 57, 58, 59)
