SYSTEMS AND METHODS FOR CLOSING AN APERTURE IN A BODILY TISSUE
Systems and methods for closing an aperture in a bodily tissue. In at least one embodiment of a system for closing an aperture in a targeted mammalian tissue, the system comprises a first catheter having a lumen defined therethrough, a coil positioned within the lumen of the first catheter, and a shaft positioned within the lumen of the catheter, the shaft operable to position the coil at the targeted tissue, wherein the coil may be positioned within the aperture of the targeted tissue to close said aperture.
1 . A method for closing an aperture in a targeted mammalian tissue, the method comprising the steps of:
introducing a catheter to the targeted tissue, the catheter having a lumen defined therethrough;
inserting a coil within the lumen of the catheter;
inserting a shaft within the lumen of the catheter, the shaft operable to position the coil at a targeted tissue; and
positioning the coil within the aperture of the targeted tissue, wherein at least part of the coil is present on a first side of the targeted tissue, and wherein at least part of the coil is present on a second side of the targeted tissue.
2 . The method of claim 1 , wherein the coil comprises a first configuration and a second configuration.
3 . The method of claim 2 , wherein the first configuration is uncompressed, and wherein the second configuration is compressed.
4 . The method of claim 2 , further comprising the step of pushing the coil using the shaft so that the changes from a first configuration to a second configuration.
5 . The method of claim 1 , further comprising the step of pushing the coil using the shaft so that the coil compresses to close the aperture of the targeted tissue.
6 . The method of claim 1 , further comprising the step of twisting the coil using the shaft so that the coil compresses to close the aperture of the targeted tissue.
7 . The method of claim 1 , wherein the targeted tissue is an atrial wall of a heart.
8 . The method of claim 1 , wherein the step of inserting a coil within the lumen of the catheter comprises the step of inserting a guide wire within the lumen of the catheter prior to insertion of the coil so that the guide wire may facilitate insertion of the coil.
9 . The method of claim 1 , wherein the step of positioning the coil results in closure of the aperture of the targeted tissue.
10 . The method of claim 1 , wherein the step of introducing a catheter to the targeted tissue further comprises engagement of the targeted tissue by the catheter.
11 . A system for closing an aperture in a targeted mammalian tissue, the system comprising:
a first catheter having a lumen defined therethrough;
a coil positioned within the lumen of the first catheter; and
a shaft positioned within the lumen of the catheter, the shaft operable to position the coil at the targeted tissue;
wherein the coil may be positioned within an aperture of the targeted tissue to close said aperture.
12 . The system of claim 11 , wherein the coil is radiopaque.
13 . The system of claim 11 , wherein the first catheter comprises a delivery catheter, and wherein the coil and the shaft are positioned within the delivery catheter.
14 . The system of claim 13 , further comprising a second catheter having a lumen defined therethrough, wherein the second catheter comprises an engagement catheter, and wherein the delivery catheter is positioned within the lumen of the engagement catheter.
15 . The system of claim 11 , wherein when the coil is positioned within the aperture of the targeted tissue, at least part of the coil is present on a first side of the targeted tissue, and at least part of the coil is present on a second side of the targeted tissue.
16 . The system of claim 11 , wherein the coil comprises a memory, and wherein the memory comprises a first configuration and a second configuration.
17 . The system of claim 16 , wherein the first configuration is uncompressed, and wherein the second configuration is compressed.
18 . The system of claim 16 , wherein the shaft is further operable to push the coil so that the coil changes from a first configuration to a second configuration.
19 . The system of claim 11 , wherein the shaft is further operable to push the coil so that the coil compresses to close the aperture of the targeted tissue.
20 . The system of claim 11 , wherein the shaft is further operable to twist the coil so that the coil compresses to close the aperture of the targeted tissue.
21 . The system of claim 11 , wherein the targeted tissue is an atrial wall of a heart.
22 . The system of claim 11 , further comprising a guide wire positioned within the lumen of the catheter prior to positioning the coil within the lumen of the catheter so that the guide wire may facilitate positioning of the coil.
23 . The system of claim 14 , wherein the engagement catheter is operable to engage the targeted tissue.
24 . A system for closing an aperture in a targeted mammalian tissue, the system comprising:
an engagement catheter having a lumen defined therethrough;
a delivery catheter having a lumen defined therethrough, the delivery catheter positioned within the lumen of the engagement catheter;
a coil positioned within the lumen of the delivery catheter, the coil comprising a first configuration and a second configuration; and
a shaft positioned within the lumen of the catheter, the shaft operable to position the coil at a targeted tissue;
wherein the coil may be positioned within an aperture of the targeted tissue to close said aperture.
