Patent ID: 7357601

Claim:
An adaptive coupling for joining a conduit to a barrier sheet through which the conduit passes, the barrier sheet movable axially relative to the conduit, the adaptive coupling comprising: a tubular member configured to allow passage of the conduit through an entirety of the tubular member, the tubular member having a first end and a second end, the first end having a base configured to sealably join the tubular member to the sheet; an extensible boot configured to allow passage of the conduit through an entirety of the extensible boot, the extensible boot having a first end and a second end, the first end sealedly joined to the second end of the tubular member such that the first end of the extensible boot is movable in unison with the tubular member, the second end sealably and fixably joinable to the conduit such that the first end of the extensible boot is movable axially relative to the second end of the extensible boot when the second end of the extensible boot is sealedly and fixedly joined to the conduit and the tubular member moves axially; and an access port, wherein a substantially leakless seal is formed between the barrier sheet and the conduit when the base of the tubular member is sealedly joined to the sheet and the second end of the extensible boot is sealedly and fixedly joined to the conduit.
