Abstract

A suturing device and method of use involve inserting the device into a hole, positioning material around the hole into a notch of the device, passing a needle through a cavity in the device and the material positioned in the notch, and lining up an eye of the needle with a portal for passage of a suture. A suture is then passed through the eye of the needle and the needle is removed from the material (such as skin and fascia) with the suture. The suture is then removed and the process is repeated with another end of the suture at another location through the material, around the hole. When the suture is passed through the second point of penetration, the suture now extends both into and out of the material at different points around the hole and can be tied.

Claims

1. A suturing kit comprising:

an elliptical cone with a wider base compared to a narrower apex at opposite ends of said elliptical cone, said base of said cone forming a unitary structure with an elongated handle, such that a side of said elliptical cone adjacent to said handle;

a notch cut into one side of said elliptical cone, extending partially between said base and said apex;

at least one needle guide cavity, extending in a straight path from a needle guide portal at said base of said cone, through said base of said cone, interrupted by said notch and continuing through said cone, having an exit portal situated between said notch and said apex of said cone, said needle guide cavity terminating before said apex;

at least one curved suture guide cavity extending between a suture guide portal located substantially at said base of said elliptical cone and opening into said needle guide cavity at a point between said notch and said exit portal;

a needle having a length longer than said needle guide cavity and having an eye, said eye aligning with said exit portal when fully inserted in said needle guide portal.

2. The kit of claim 1, wherein said suture guide portal is located at said base of said elliptical cone.

20. The device of claim 1, wherein said needle and at least a part of said needle guide cavity are elliptical.

3. A suturing device comprising:

a base and an apex, said base and said apex being located at opposite ends of said suturing device;

a notch extending into one side of said suturing device, said notch extending partially between said base and said apex;

at least one needle guide cavity at said base, extending in a straight path through said suturing device, between said base and said notch, and between said notch and said apex;

an exit portal situated between said notch and said apex of said suturing device;

at least one curved suture guide cavity extending between a suture guide portal located substantially at said base and opening into said needle guide cavity at a point between said notch and said exit portal of said suturing device.

4. The suturing device of claim 3, wherein said suturing device comprises an elliptical cone formed between said base and said apex of said suturing device.

5. The suturing device of claim 4, wherein said base of said cone forms a unitary structure with a handle.

6. The suturing device of claim 5, wherein said needle guide cavity terminates at a point before said apex.

7. The suturing device of claim 6, wherein said elliptical cone is at least partially wrapped in foam between said notch and said handle.

8. A kit comprising said suturing device of claim 3 and a needle having a length longer than said needle guide cavity;

wherein said needle further comprises an eye, said eye aligning with said exit portal when said needle is fully inserted in said needle guide portal.

9. A method of suturing, comprising the steps of:

inserting an apex of a suturing device into a pre-existing hole until material around said hole is positioned within a notch cut into one side of said suturing device between a base and said apex thereof, wherein said base and said apex are located at opposite ends of said suturing device;

inserting a needle having an eye through a needle guide portal of said suturing device;

penetrating said material positioned within said notch with said inserted needle;

continuing insertion of said needle until said eye of said needle aligns with an exit portal of said suturing device, wherein said exit portal is situated between said notch and said apex of said suturing device;

inserting a first end of a first suture through a suture guide portal of said suturing device;

pushing said suture through said eye of said needle and said exit portal;

at least partially extracting said needle from said suturing device until said suture, still passing through said eye of said needle, passes through said material at a point of said penetration;

rotating said suturing device with respect to said hole;

repeating at a second position of said material with a second end of said suture at least said step of penetration, said step of continuing, said step of inserting a first end of said suture, said step of pushing, and said step of at least partially extracting;

extracting said suturing device from said hole.

10. The method of claim 9, wherein said pre-existing hole is a tissue defect, and wherein said material around said hole comprises bodily tissue;

and said method first comprises a step of removing a trocar from a tissue defect.

11. The method of claim 9, wherein said step of inserting an apex of a suturing device into a pre-existing hole further comprises rotating and manipulating said device, while maximizing an amount of tissue positioned in said notch.

12. The method of claim 9, wherein said step of at least partially extracting said needle further comprises completely extracting said needle from said suturing device.

13. The method of claim 9, wherein said step of rotating said suturing device further comprises rotating said device substantially 180 degrees.

14. The method of claim 9, wherein said suturing device is elliptical, such that rotating substantially 180 degrees causes said tissue defect to stretch such that a first and second said penetration are spaced further apart than compared to carrying out said method with a corresponding circular device.

15. The method of claim 9, wherein said step of extracting said suture device further comprises a step of securing said ends of said suture and suturing said pre-existing hole.

16. The method of claim 9, wherein said first suture is looped through a second suture, and wherein each end of said first and second sutures are inserted through said suture guide portal after each step of inserting said needle and penetrating said material.

17. A method of suturing, comprising the steps of:

inserting a suturing device into a pre-existing hole until material around said hole is positioned within a notch cut into one side of said suturing device between a base and an apex thereof, wherein said base and said apex are located at opposite ends of said suturing device;

inserting a needle having an eye through a needle guide portal at said base of said suturing device;

penetrating said material with said inserted needle;

continuing insertion of said needle until said eye of said needle aligns with an exit portal of said suturing device, wherein said exit portal is situated between said notch and said apex of said suturing device;

inserting a first end of a suture through a suture guide portal of said suturing device;

pushing said suture through said eye of said needle and said exit portal;

at least partially extracting said needle from said suturing device until said suture, still passing through said eye of said needle, passes through said material at a point of said penetrating;

carrying out said step of penetrating said material at a second point on said material, inserting a second end of said suture through said suture guide portal, and at least partially extracting said needle until said suture passes through said material a second time.

18. The method of claim 18, wherein said suturing device comprises an elliptical cone with said exit portal at a tapered end thereof.

19. The method of claim 18, wherein said step of penetrating said material is carried out at a third and fourth point with a third and fourth end of an X-shaped suture.
