SUTURE-BASED CLOSURE WITH HEMOSTATIC TRACT PLUG
First Claim
1. A device for closing a passage through tissue communicating with a body lumen, the device comprising:
- an elongate device body extending from a proximal end to a distal end;
a sheath disposed at the distal end of the device for disposition within a body lumen during use;
at least one hollow needle disposed within a corresponding needle lumen of the elongate body, the at least one hollow needle being selectively advancable through the needle lumen;
at least one suture-anchor ejection mandrel disposed within the at least one hollow needle, the at least one suture-anchor ejection mandrel being selectively advancable through the hollow needle;
a suture-anchor and suture disposed within the hollow needle for ejection out a distal end of the hollow needle by the suture-anchor ejection mandrel, a distal end of the suture being attached to the suture-anchor;
a needle guide disposed between the sheath and the proximal end of the elongate body, the needle guide comprising at least one needle port through which the corresponding hollow needle can exit during use;
at least one hemostatic plug disposed over the needle port, within a receiving recess disposed about the needle port on an exterior surface of the needle guide so as to be penetrated by a corresponding hollow needle during use;
a needle advancement assembly disposed on or within the elongate body configured to selectively deploy the at least one hollow needle through the needle port and into tissue adjacent the passage during use; and
a suture-anchor ejection assembly disposed on or within the elongate body configured to selectively advance the at least one suture-anchor ejection mandrel so as to eject the suture-anchor from the hollow needle to a location adjacent a wall of the body lumen during use.

Abstract
Devices for closing a passage through tissue communicating with a body lumen. The device may include an elongate body, a sheath disposed at the distal end of the device for disposition within a body lumen, a hollow needle disposed within a needle lumen of the body, the needle being selectively advancable through the needle lumen, a suture-anchor ejection mandrel disposed within the hollow needle that is also selectively advancable through the hollow needle, a suture-anchor and suture disposed within the hollow needle, a distal end of the suture attached to the suture anchor for ejection out the hollow needle by the mandrel. A needle guide disposed between the sheath and proximal end of the body may include a needle port through which the needle can exit. A hemostatic plug is disposed over the needle port so as to be penetrated by the needle upon exiting the port.

8. A device for closing a passage through tissue communicating with a body lumen, the device comprising:
-
an elongate device body extending from a proximal end to a distal end; a sheath disposed at the distal end of the device for disposition within a body lumen during use; a pair of hollow needles disposed within corresponding needle lumens of the elongate body, the hollow needles being selectively advancable through the needle lumens; a pair of suture-anchor ejection mandrels disposed within the hollow needles, each suture-anchor ejection mandrel being selectively advancable through a corresponding one of the hollow needles; a suture-anchor and suture disposed within each hollow needle, a distal end of each suture being attached to the suture-anchor for ejection out a distal end of the corresponding hollow needle by the corresponding suture-anchor ejection mandrel; a needle guide disposed between the sheath and the proximal end of the elongate body, the needle guide comprising a pair of needle ports, each of which through a respective one of the corresponding hollow needles can exit during use; a hemostatic plug disposed over each needle port, within a receiving recess disposed about each needle port on an exterior surface of the needle guide so as to be penetrated by a corresponding hollow needle during use; a needle advancement assembly disposed on or within the elongate body configured to selectively deploy the hollow needles through the needle ports and into tissue adjacent the passage during use; and a suture-anchor ejection assembly disposed on or within the elongate body configured to selectively advance the suture-anchor ejection mandrels so as to eject the suture-anchors from the corresponding hollow needles to a location adjacent a wall of the body lumen during use. - View Dependent Claims (9, 10, 11, 12, 13, 14)

15. A device for closing a passage through tissue communicating with a body lumen, the device comprising:
-
an elongate device body extending from a proximal end to a distal end; a sheath disposed at the distal end of the device for disposition within a body lumen during use; a pair of hollow needles disposed within corresponding needle lumens of the elongate body, the hollow needles comprising an anterior needle and a posterior needle and being selectively advancable through the needle lumens; a pair of suture-anchor ejection mandrels disposed within the hollow needles, each suture-anchor ejection mandrel being selectively advancable through a corresponding one of the hollow needles; a suture-anchor and suture disposed within each hollow needle, a distal end of each suture being attached to the suture-anchor for ejection out a distal end of the corresponding hollow needle by the corresponding suture-anchor ejection mandrel; a needle guide disposed between the sheath and the proximal end of the elongate body, the needle guide comprising anterior and posterior needle ports through which the corresponding anterior and posterior hollow needles can exit during use, the anterior needle port being disposed anterior relative to the posterior needle port along the needle guide; a hemostatic plug disposed over each needle port, within a receiving recess disposed about each needle port on an exterior surface of the needle guide so as to be penetrated by a corresponding hollow needle during use; a needle advancement assembly disposed on or within the elongate body configured to selectively deploy the hollow needles through the needle ports and into tissue adjacent the passage during use; a suture-anchor ejection assembly disposed on or within the elongate body configured to selectively advance the suture-anchor ejection mandrels so as to eject the suture-anchors from the corresponding hollow needles to a location adjacent a wall of the body lumen during use; wherein the needle advancement assembly, the suture-anchor ejection assembly, the suture-anchor ejection mandrels, and the hollow needles are together detachable from the distal end of the device to allow a user to easily access an end of the suture opposite the suture-anchor once the suture-anchor has been deployed to a location adjacent the wall of the body lumen during use. - View Dependent Claims (16, 17, 18, 19, 20)
