Craniotomy Plugs
Described herein is a cranial plug for a burr hole or a cranial perforation made in a skull during brain surgery, the cranial plug being flexible and having a bottom portion and side walls extending upwards from the bottom portion, the bottom portion and the side walls formed in a concave or substantially concave shape, or alternatively, forming a concave or substantially concave shape when inserted into a burr hole or cranial perforation.
1 . A cranial plug for a burr hole or a cranial perforation made in a skull during brain surgery, the cranial plug having a bottom portion and side walls extending upwards from the bottom portion, the bottom portion and the side walls forming a substantially concave shape.
2 . The cranial plug of claim 1 , wherein the side walls comprise at least two tabs.
3 . The cranial plug of claim 2 , wherein the tabs are not in contact with each other.
4 . The cranial plug of claim 2 , wherein the tabs have different heights.
5 . The cranial plug of claim 2 , wherein the tabs are the same height.
6 . The cranial plug of claim 1 , wherein the side walls have a top surface and wherein the top surface is not in contact with any portion of the cranial plug.
7 . The cranial plug of claim 1 , wherein the side walls are continuous.
8 . The cranial plug of claim 7 , wherein the side walls comprise at least one perforation.
9 . The cranial plug of claim 1 , wherein the cranial plug comprises a bioabsorbable material.
10 . The cranial plug of claim 9 , wherein the bioabsorbable material is selected from the group consisting of collagen, polyglycolide, poly(lactic acid), copolymers of lactic acid, glycolic acid, poly-L-lactide, poly-L-lactate, copolymers of polyethylene glycol, polybutylene terephthalate and combinations thereof.
11 . The cranial plug of claim 9 , wherein the bioabsorbable material is flexible.
12 . The cranial plug of claim 10 , wherein the bioabsorbable material is collagen.
13 . A cranial plug for a burr hole or a cranial perforation made in a skull during brain surgery, the cranial plug having a bottom portion and side walls, wherein the cranial plug is substantially flat prior to insertion into a burr hole or a cranial perforation and wherein the cranial plug is substantially concave, with the side walls extending upwards from the bottom portion when the cranial plug is inserted into a burr hole or a cranial perforation.
14 . The cranial plug of claim 13 , wherein the side walls comprise at least two tabs.
15 . The cranial plug of claim 14 , wherein the tabs are not in contact with each other.
16 . The cranial plug of claim 14 , wherein the tabs have different heights.
17 . The cranial plug of claim 14 , wherein the tabs are the same height.
18 . The cranial plug of claim 13 , wherein the side walls have a top surface and wherein the top surface is not in contact with any portion of the cranial plug.
19 . The cranial plug of claim 13 , wherein the side walls are continuous.
20 . The cranial plug of claim 19 , wherein the side walls comprise at least one perforation.
21 . The cranial plug of claim 13 , wherein the cranial plug comprises a bioabsorbable material.
22 . The cranial plug of claim 21 , wherein the bioabsorbable material is selected from the group consisting of collagen, polyglycolide, poly(lactic acid), copolymers of lactic acid, glycolic acid, poly-L-lactide, poly-L-lactate, copolymers of polyethylene glycol, polybutylene terephthalate and combinations thereof.
23 . The cranial plug of claim 21 , wherein the bioabsorbable material is flexible.
24 . The cranial plug of claim 22 , wherein the bioabsorbable material is collagen.
