Described herein are devices and techniques for no-hole-prep installation of miniaturized suture anchors into bone. A system for tissue repair comprises a suture anchor (100) having a longitudinal axis and including a body defining a hollow interior, the hollow interior including a proximal region (111b) having a first cross-section, a distal region (111a) having a second cross-section, and a medial transition region (113) positioned between the proximal region and the distal region, and diametrically opposed first and second apertures (105) in the body, forming a bore extending through the body transversely to the longitudinal axis, the bore sized to receive one or more flexible members (107) and a driver (200) including a shaft (201) having a proximal portion (201b) having a first complementary cross- section, wherein the first complementary cross-section is an inverse shape complementary to the first cross-section, the proximal portion adapted to engage with the proximal region of the body of the suture anchor a distal portion (201a) having a second complementary cross-section, wherein the second complementary cross-section is an inverse shape complementary to the second cross-section, the distal portion adapted to engage with the distal region of the body of the suture anchor a medial transition portion (203) extending between the proximal portion and the distal portion, the medial transition portion configured to mate with the medial transition region of the body of the suture anchor to form a suture passage (301), the suture passage in communication with the bore and adapted for routing the one or more flexible members around the shaft, and a tip (205) extending distally from the distal portion of the shaft and beyond the distal region of the body of the suture anchor.
