As far as I know, you have 2 options.

- Order a new hardware wallet (e.g, Ledger or Trezor) and then import your seed phrase to recover your assets.
- Use a compatible software wallet preferably Electrum and import your 24 word seed phrase for you to be able to transfer your BTC to another address. And make sure that you have verified the Electrum before using it.

But, just to be safe, I hope your missing ledger device has a strong pin code to reduce the risk of your coins from being stolen.
