The system of claim 1, wherein the engagement mechanism comprises threads configured for removably engaging mating threads of the attaching device. 10. The system of claim 9, wherein the threads are positioned about a proximal end of the occluding device, and wherein the mating threads are positioned about a proximal end of the attaching device. 11. The system of claim 1, wherein the engagement mechanism comprises a locking collar configured for removably engaging a mating collar of the attaching device. 12. The system of claim 11, wherein the locking collar is positioned about a proximal end of the occluding device, and wherein the mating collar is positioned about a proximal end of the attaching device. 13. The system of claim 1, wherein the occluding device further comprises an engagement element configured for releasably receiving a delivery instrument for insertion of the occluding device at least partially within the opening of the port. 14. The system of claim 13, wherein the engagement element is positioned about a proximal end of the occluding device. 15. The system of claim 13, wherein the engagement element comprises a slot configured for releasably receiving a distal end of the delivery instrument. 16. A system comprising: an attaching device comprising: a port defining an opening extending along a longitudinal axis defined by the attaching device, anda coil attached to the port and configured for advancing at least partially into a tissue wall such that at least a portion of the coil becomes disposed between a first surface and a second surface of the tissue wall; andan occluding device comprising: a locking collar configured for removably engaging a mating collar of the attaching device such that the occluding device is fixed relative to the port of the attaching device along the longitudinal axis defined by the attaching device when the locking collar and the mating collar are engaged, anda valve being positioned at least partially within the coil and occluding the opening of the port when the locking collar and the mating collar are engaged. 17. The system of claim 16, wherein the locking collar is positioned about a proximal end of the occluding device, and wherein the mating collar is positioned about a proximal end of the attaching device. 18. The system of claim 16, wherein the valve comprises a one-way valve configured to yield to pressure applied to a proximal end of the valve. 19. A system comprising: an attaching device comprising:a port defining an opening extending along a longitudinal axis defined by the attaching device; anda coil attached to the port and configured for advancing at least partially into a tissue wall such that at least a portion of the coil becomes disposed between a first surface and a second surface of the tissue wall, wherein the coil comprises a proximal end and a distal end, wherein the proximal end is attached to the port, wherein a radius of the coil increases along at least a portion of a length of the coil from the proximal end to the distal end; andan occluding device comprising:a locking collar configured for removably engaging a mating collar of the attaching device such that the occluding device is fixed relative to the port of the attaching device along the longitudinal axis defined by the attaching device when the locking collar and the mating collar are engaged; anda valve extending distally beyond the locking collar, the valve being positioned at least partially within the coil and occluding the opening of the port when the locking collar and the mating collar are engaged. 20. The system of claim 19, wherein the locking collar is positioned about a proximal end of the occluding device, and wherein the mating collar is positioned about a proximal end of the attaching device.
