초록 ▼

There is disclosed a threaded tissue tack for use in approximating and securing a pair of tissue sections together. The threaded tissue tack has a central body portion and first and second screws extending from opposite ends of the central body portion. The first screw includes a left-hand thread and the second includes a right-hand thread. Engagement structure is provided on the central body portion to rotate the threaded tissue tack about its longitudinal axis and into the pair of tissue sections. There is also disclosed a tack driver for rotating the threaded tissue tack into the tissue. Guards are provided intermediate first and second ends of the central body portion and the first and second screws to protect surrounding tissue from the tack driver.

1. A system for approximating and securing a pair of tissue sections together comprising: a tissue tack including a central body portion and a first screw and a second screw extending from opposite ends of the central body portion, the central body portion including a driven structure;a first guard located between the first screw and the central body portion and a second guard located between the second screw and the central body portion, wherein diameters of the first and second guards are substantially greater than a diameter of the central body portion; anda tack driver for rotating the tissue tack into a pair of tissue sections simultaneously, the tack driver including a housing having a power source and drive structure extending from the housing and movable by the power source, wherein the drive structure of the tack driver is engageable with the driven structure of the tissue tack to rotate the tissue tack about its longitudinal axis. 2. The system as recited in claim 1, wherein the drive structure includes a rotatable drive shaft having a helical thread formed thereon such that the helical thread is engageable with a plurality of slots formed in the circumference of the central body portion to rotate the tissue tack. 3. The system as recited in claim 1, further comprising a support bar extending distally from the housing such that the tissue tack rests on the support bar. 4. The system as recited in claim 1, wherein the first screw includes a conical member having a base and a tissue penetrating tip. 5. The system as recited in claim 4, wherein a diameter of the base is substantially identical to a diameter of the central body portion. 6. The system as recited in claim 1, wherein the second screw includes a conical member having a base and a tissue penetrating tip. 7. The system as recited in claim 1, wherein the first and second guards are disk shaped. 8. The system as recited in claim 1, wherein the first and second screws and the central body portion are formed of a biocompatible material. 9. The system as recited in claim 1, wherein the first and second screws and the central body portion are formed of a bioabsorbable material. 10. A system for approximating and securing a pair of tissue sections together comprising: a tissue tack including a central body portion and a first screw and a second screw extending from opposite ends of the central body portion, the central body portion including a driven structure; anda tack driver for rotating the tissue tack into a pair of tissue sections simultaneously, the tack driver including a housing having a power source and drive structure extending from the housing and movable by the power source, wherein the drive structure of the tack driver is engageable with the driven structure of the tissue tack to centrally drive the tissue tack about its longitudinal axis and includes a rotatable drive shaft having a helical thread formed thereon such that the helical thread is engageable with a plurality of slots formed in the circumference of the central body portion to rotate the tissue tack. 11. The system as recited in claim 10, further comprising a first guard located between the first screw and the central body portion and a second guard located between the second screw and the central body portion. 12. The system as recited in claim 11, wherein diameters of the first and second guards are substantially greater than a diameter of the central body portion.
