Abstract: A needle driver can include a first jaw hosting a first shaft and a second jaw hosting a second shaft. The first shaft hosts a first roller and a first set of teeth. The second shaft hosts a second roller and a second set of teeth. The second jaw moves relative to the first jaw between an open position and a closed position. The first set of teeth meshes with the second set of teeth when the second jaw is in the closed position such that (a) the first set of teeth can drive the second set of teeth and (b) the first roller and the second roller can drive a needle therebetween when the first set of teeth drives the second set of teeth.

Abstract: A rotational driver that comprises a interactive portion, wherein each interactive portion comprises a first extended member and a second extended member, a rotational system and a linear motion system, wherein the rotational driver permits a left or right handed surgeons to perform the surgical suturing procedure in a less complicated and more secure way by allowing more control over the angled suturing needle and the area to be stitched, even when the suturing area is small, deep, and/or restricted. Also the rotational driver comprises several configurations at the interactive portion ends to provide selected angles for the needle during the suturing procedure.

Abstract: This disclosure enables various threading devices (e.g., suturing devices) that can sequentially send a plurality of carriers (e.g., needle caps, sleeves) to an object (e.g., animate, inanimate, human tissue, organ tissue, heart tissue) or sequentially receive a plurality of carriers (e.g., needle caps, sleeves) from an object (e.g., animate, inanimate, human tissue, organ tissue, heart tissue). For example, some threading devices can sequentially send some carriers in a relatively rapid succession or some threading devices can sequentially receive some carriers in a relatively rapid succession.
