Abstract

Surgical devices permitting a surgeon to access repeatedly tissue at a particular surgical site in a patient to perform multiple surgeries over time. The devices have two substantially planar and parallel leaves that are sterile, nonresorbable, and biocompatible. Each leaf forms a continuous structure and defines the entire longitudinal length of the device to accommodate the size and location of the surgical site. A base member is located in situ and adjacent the surgical site. An anchoring surface secures the device to the tissue of the patient at the surgical site. The leaves have a conjoined portion such that a manual force is required to separate the leaves, thereby expeditiously creating a pathway through which access to the tissue at the surgical site is realized with minimal tissue dissection, and the proximal ends of the leaves are not conjoined to facilitate separation of the leaves and creation of the pathway.

Claims

1. A surgical access device having a longitudinal axis and permitting a surgeon to access repeatedly tissue at a particular surgical site in a patient to perform multiple surgeries over time, the device comprising:

first and second substantially planar leaves that are sterile, nonresorbable, and biocompatible, each leaf forming a continuous structure between distal and proximal ends along a longitudinal length, each leaf lying in parallel along the longitudinal axis of the device, each leaf defining the entire longitudinal length of the device to accommodate the size and location of the particular surgical site, and each leaf having areas of higher porosity and areas of lesser porosity, wherein the distal ends of the leaves are freely movable;

a base member formed from at least one of, or as a separate structure secured to at least one of, the distal ends of the planar leaves, the base member adapted to be located in situ and adjacent the surgical site; and

an anchoring surface located on at least one of the leaves or on the base member, the anchoring surface securing the device to the tissue of the patient at the surgical site;

the leaves being conjoined along the longitudinal length of the leaves to form a conjoined portion such that a manual force is required to separate the leaves, thereby expeditiously creating a space or pathway through which access to the tissue at the surgical site is realized with minimal tissue dissection, and the proximal ends of the leaves are not conjoined to facilitate separation of the leaves and creation of the space or pathway.

2. The device of claim 1 wherein at least one leaf further comprises at least one anchoring surface.

3. The device of claim 2 wherein the anchoring surface further comprises at least one suture.

4. The device of claim 1 wherein at least a portion of the device is radiopaque.

5. The device of claim 1 further comprising localizing markings.

6. The device of claim 1 further comprising a catheter or cannula.

7. The device of claim 1 wherein the device is a contrasting color to tissue.

8. The device of claim 1, wherein the distal ends of the leaves have higher porosity and the conjoined portion has lesser porosity.

9. The device of claim 1, wherein the distal ends of the leaves are freely movable such that they may be oriented generally normal to the proximal ends of the leaves.

10. The device of claim 1, wherein the manual force is between 1 and 4 pounds per linear inch.

11. The device of claim 1, wherein the leaves are flexible.

12. A surgical access device having a longitudinal axis and permitting a surgeon to access repeatedly tissue at a particular surgical site in a patient to perform multiple surgeries over time, the device comprising:

first and second substantially planar leaves that are sterile, nonresorbable, and biocompatible, each leaf forming a continuous structure between distal and proximal ends along a longitudinal length, each leaf lying in parallel along the longitudinal axis of the device, and each leaf defining the entire longitudinal length of the device to accommodate the size and location of the particular surgical site, wherein the distal ends of the leaves are freely movable;

a base member formed from at least one of or as a separate structure secured to at least one of, the distal ends of the planar leaves, the base member adapted to be located in situ and adjacent the surgical site; and

an anchoring surface located on at least one of the leaves or on the base member, the anchoring surface securing the device to the tissue of the patient at the surgical site;

the leaves being conjoined along the longitudinal length of the leaves to form a conjoined portion such that a manual force is required to separate the leaves, thereby expeditiously creating a space or pathway through which access to the tissue at the surgical site is realized with minimal tissue dissection, and the proximal ends of the leaves are not conjoined to facilitate separation of the leaves and creation of the space or pathway.

13. The device of claim 12, wherein the distal end of each leaf has higher porosity and the conjoined portion has lesser porosity.

14. The device of claim 12, wherein the distal ends of the leaves are freely movable such that they may be oriented generally normal to the proximal ends of the leaves.

15. The device of claim 12, wherein the manual force is between 1 and 4 pounds per linear inch.

16. The device of claim 12, wherein the leaves are flexible.

17. The device of claim 12 wherein at least one leaf further comprises at least one anchoring surface.

18. The device of claim 17 wherein the anchoring surface further comprises at least one suture.

19. The device of claim 12 wherein at least a portion of the device is radiopaque.

20. The device of claim 12 further comprising localizing markings.

21. The device of claim 12 further comprising a catheter or cannula.

22. The device of claim 12 wherein the device is a contrasting color to tissue.
