Abstract
A profile includes: a sidewall, a lumen for a fluid path, and an end, the profile including a thermoset material, wherein the profile includes a sealed end without an external bonding material, wherein the sealed end withstands a seal integrity pressure test of at least 1 psi, such as at least 5 psi, such as at least 10 psi, such as at least 15 psi, or even at least 20 psi air pressure for about 30 minutes under dry and wet conditions.
Claims20
A profile comprises:
- a sidewall, a lumen for a fluid path, and an end, the profile comprises a thermoset material, wherein the profile includes a sealed end without an external bonding material, wherein the sealed end withstands a seal integrity pressure test of at least 1 psi, such as at least 5 psi, such as at least 10 psi, such as at least 15 psi, or even at least 20 psi air pressure for about 30 minutes under dry and wet conditions.
A method of providing a sterile terminus of a profile comprising:
- providing the profile having a sidewall, a lumen for a fluid path, and an end, the profile comprising a thermoset material;
- providing a surface activation treatment to a surface adjacent to the end of the profile;
- and
- sealing the end to provide the terminus of the lumen, wherein the sealed end has a mechanical strength greater than or equal to a mechanical strength of the sidewall.
