Tissue surface piercing system and methods
A system, including a needle guide defining a path of travel of a needle inserted through the guide, and a tissue manipulator configured to approximate tissue and said needle guide and to position at least a portion of the tissue in the path of travel of the needle, and wherein the tissue manipulator and the needle guide are alignable such that the path of travel crosses a same surface of the tissue a plurality of times.
1 . A tissue-pexy system, comprising:
a needle guide having an elongated structure extending between a first end portion and a second end portion, the elongated structure having—
a cavity between the first end portion and the second end portion, wherein the cavity is configured to receive a portion of tissue, and
a lumen configured to receive a needle, wherein the lumen includes a first lumen portion extending between the first end portion and the cavity and a second lumen portion extending between the second end portion and the cavity; and
a tissue manipulator having a body and one or more deployable probes configured to be moved relative to the body between a first retracted position and a second deployed position, wherein the one or more deployable probes are configured to direct the portion of tissue into the cavity in the second deployed position,
wherein the system is configured such that, when the one or more deployable probes directs the portion of tissue into the cavity and a needle is advanced through the lumen, the needle is configured to traverse the cavity and pierce the portion of tissue as it moves from the first lumen portion to the second lumen portion.
2 . The system of claim 1 , wherein the portion of tissue has an outer surface and an inner surface, wherein the system is configured to pierce the outer surface in at least two locations without piercing the inner surface.
3 . The system of claim 1 , wherein the cavity has an inner surface, a first lateral surface, and a second lateral surface, and wherein—
the first lateral surface has a first opening in fluid communication with the first lumen portion, and
the second lateral surface has a second opening in fluid communication with the second lumen portion,
wherein the first opening and the second opening are configured to receive the needle as it is advanced through the lumen from the first lumen portion to the second lumen portion.
4 . The system of claim 3 , wherein the system is configured such that the needle penetrates the portion of tissue between the probe and the inner surface of the cavity as it advances from the first opening to the second opening.
5 . The system of claim 1 , wherein a geometry of the probe is complementary to a geometry of the cavity.
6 . A system, comprising:
a needle guide having:
an elongated structure extending between a first end portion and a second end portion,
a cavity between said first end portion and said second end portion, and
a lumen configured to receive a needle, wherein said lumen includes a first lumen portion extending between said first end portion and said cavity and a second lumen portion extending between said second end portion and said cavity, and wherein said needle guide defines a path of travel of said needle inserted through said guide; and
a tissue manipulator having a body and configured to approximate tissue and said needle guide and to position at least a portion of said tissue in said path of travel of said needle via at least one deployable probe configured to be moved relative to said body between a first retracted position and a second deployed position; and
wherein said tissue manipulator and said needle guide are alignable such that said path of travel is configured to cross a same surface of said tissue a plurality of times.
7 . The system of claim 6 , wherein said path of travel is exposed by said cavity.
8 . The system of claim 6 , wherein said deployable probe comprises a light-emitting element.
9 . The system of claim 6 , wherein said tissue manipulator comprises a shell and said at least one deployable probe extends radially outwards from said shell.
10 . The system of claim 6 , wherein said tissue manipulator comprises a handle and wherein one of the length of extension, the position, and spatial orientation of said at least one deployable probe is adjustable in relation to said handle.
11 . The system of claim 6 , wherein geometries of at least a portion of said guide and at least a portion of said tissue manipulator are complementarily.
12 . The system of claim 6 , wherein at least a portion of said tissue manipulator is flexible.
13 . The system of claim 6 , wherein said tissue manipulator comprises at least one light-emitting diode.
14 . The system of claim 6 , wherein said tissue manipulator comprises a first magnet and said needle guide comprises a second magnet.
15 . The system of claim 6 , wherein said needle guide comprises a second opening configured to direct an exit path of a needle out of said needle guide.
16 . The system of claim 15 , wherein said second opening of said needle guide is configured to couple to a tissue of a subject.
17 . The system of claim 6 , wherein said needle guide is a self-coupling needle guide.
18 . The system of claim 6 , wherein said needle guide comprises a clip such that a spatial orientation of said needle guide is independently maintained fixed in relation to said tissue manipulator such that said path of travel crosses a same surface of said tissue a plurality of times.
