Abstract

Devices and methods for minimally invasive suturing are disclosed. One suturing device for minimally invasive suturing includes a proximal section a distal end, and an intermediate region therebetween. The device includes a suture head assembly having a suturing needle with a pointed end and a second end. The suturing needle is capable of rotating about an axis approximately perpendicular to a longitudinal axis of the device, wherein the pointed end of the suturing needle is positioned within the suture head assembly prior to deployment of guides that are adapted and configured to guide the needle around a circular path when advanced by a drive mechanism having a needle driver for engaging and rotating the suturing needle.
