Abstract
Devices, systems, and methods can be used for the closure of surgical wounds. For example, surgical wounds can be closed using magnetic closure devices rather than the conventional methods of using sutures, clips, or staples. Additionally, in some implementations the magnetic closure devices provided herein are delivered laparoscopically or endoscopically via a vacuum catheter.
Claims7
A wound closure system comprising:
- a first wound closure device comprising:
- a first casing that defines a first tunnel, the first casing having a first front face surface;
- a first manifold attached on a side of the first casing opposite of the first front face;
- a first flexible magnet strip that is selectively engageable with the first casing by user insertion of the first flexible magnet strip into the first tunnel;
- and
- a plurality of first C-shaped wound approximator micro-needles extending from the first manifold and in fluid communication with the first manifold;
- and
- a second wound closure device comprising:
- a second casing that defines a second tunnel, the second casing having a second front face surface;
- a second manifold attached on a side of the second casing opposite of the second front face;
- a second flexible magnet strip that is selectively engageable with the second casing by user insertion of the second flexible magnet strip into the second tunnel;
- and
- a plurality of second C-shaped wound approximator micro-needles extending from the second manifold and in fluid communication with the second manifold,
- wherein the first flexible magnet strip is selectively magnetically coupleable with the second flexible magnet strip such that, when the first flexible magnet strip is engaged within the first tunnel and the second flexible magnet strip is engaged within the second tunnel, the first front face surface and the second front face surface are selectively magnetically coupleable to abut against each other, and
- wherein, while the first front face surface and the second front face surface are abutted against each other:
- (i) the plurality of first C-shaped wound approximator micro-needles directionally extend from the first manifold laterally away from the second casing and then turn toward the second casing and (ii) the plurality of second C-shaped wound approximator micro-needles directionally extend from the second manifold laterally away from the first casing and then turn toward the first casing.

A method of closing a wound in tissue, the method comprising:
- installing a first wound closure device on a first side of the wound, wherein the first wound closure device comprises:
- a first casing that defines a first tunnel, the first casing having a first front face surface;
- a first manifold attached on a side of the first casing opposite of the first front face;
- a first flexible magnet strip that is selectively engageable with the first casing by user insertion of the first flexible magnet strip into the first tunnel;
- and
- a plurality of first C-shaped wound approximator micro-needles extending from the first manifold and in fluid communication with the first manifold;
- installing a second wound closure device on a second side of the wound opposite of the first side of the wound, wherein the second wound closure device comprises:
- a second casing that defines a second tunnel, the second casing having a second front face surface;
- a second manifold attached on a side of the second casing opposite of the second front face;
- a second flexible magnet strip that is selectively engageable with the second casing by use insertion of the second flexible magnet strip into the second tunnel;
- and
- a plurality of second C-shaped wound approximator micro-needles extending from the second manifold and in fluid communication with the second manifold,
- wherein the first flexible magnet strip is selectively magnetically coupleable with the second flexible magnet strip such that, when the first flexible magnet strip is engaged within the first tunnel and the second flexible magnet strip is engaged within the second tunnel, the first front face surface and the second front face surface are selectively magnetically coupleable to abut against each other;
- and
- magnetically coupling the first flexible magnet strip with the second flexible magnet strip such that the first front face surface becomes generally abutted against the second front face surface, and
- wherein, while the first front face surface and the second front face surface are abutted against each other:
- (i) the plurality of first C-shaped wound approximator micro-needles directionally extend from the first manifold laterally away from the second casing and then turn toward the second casing and (ii) the plurality of second C-shaped wound approximator micro-needles directionally extend from the second manifold laterally away from the first casing and then turn toward the first casing, such that the plurality of first C-shaped wound approximator micro-needles and the plurality of second C-shaped wound approximator micro-needles draw the wound closed.
