Issued shares is a term of law and finance for the quantity of shares of a corporation, which have been allocated (allotted) and are subsequently held by shareholders. The act of creating new issued shares is called issuance, allocation or allotment. Allotment, in simplicity, is the creation of shares and their transfer to a subscriber. After allotment, a subscriber becomes a shareholder. The number of issued shares is a subset of the total authorized shares. It is that amount which the board of directors and/or shareholders have agreed to allocate. Issued shares are the sum of outstanding shares and treasury shares. (Wikipedia)

A share repurchase is a program by which a company buys back its own shares from the marketplace, usually because management thinks the shares are undervalued, reducing the number of outstanding shares. (Investopedia)

When a company issues shares of common stock for the public to buy and later decides to buy some of those shares back, that's considered a repurchase rather than a redemption. The major difference between the two is that the shares bought back in a redemption are considered a fixed-income security that is expected to be bought back by the issuer. A repurchase of shares, however, reduces the number of outstanding shares that a company has, and can increase the company's holdings so that it remains or regains majority shareholder status.
