Does Hades (The bosom of Abraham) still exist after Christ's resurrection

I've been listening to this pastor from AoC Network that has been talking about Hades as there is/was a place of torment and a place of peace, before Christ's resurrection. This is where people who God deemed as men of God or Godly men and women went before the resurrection of Jesus on the Cross. He says he believes (because the bible is not clear on this subject) that people who have died now days who have not had the opportunity to know enough about Jesus or know who he is, can make a decision to invite Jesus into their heart to be their savior, this is where they go. This sounds like the Catholic belief in Purgatory. I know the Bible isn't clear on the matter of "The Bosom of Abraham" in today's world, but I've been taught that "The Bosom of Abraham" was closed off when Jesus came back for his disciples after his death and brought them to heaven with Him. Now, this pastor from AoC says he believes that the Hades that *was* called "The Bosom of Abraham" (which this pastor describes as a place of peace) still exists (but of course is *not* called "The Bosom of Abraham" because Abraham is up in heaven,) for those who have not heard of Jesus or had the opportunity to accept his free Gift of Salvation, i.e Babies who are unborn and those who die as infant babies who cannot know Jesus yet, because they cannot understand yet. My question is: "Does the side of Hades that was once "The Bosom of Abraham" still exist? Is this what the Catholic's call Purgatory, and where is this found in the Bible?"
