“…It could potentially lead to scarring, tissue necrosis, and wound infection. Other disadvantages include time-consuming operation and the dependency on the dexterity of the surgeon for a successful surgery, specifically in the case of small vasculature, ( Mallela et al, 2021 ). Sutureless anastomosis techniques have been developed to overcome the challenges and limitations of manual suturing, which could reduce the time and invasiveness of surgeries.…”

3D structures are crucial to biological function in the human body, driving interest in their in vitro fabrication. Advances in shape-morphing materials allow the assembly of 3D functional materials with the ability to modulate the architecture, flexibility, functionality, and other properties of the final product that suit the desired application. The principles of these techniques correspond to the principles of origami and kirigami, which enable the transformation of planar materials into 3D structures by folding, cutting, and twisting the 2D structure. In these approaches, materials responding to a certain stimulus will be used to manufacture a preliminary structure. Upon applying the stimuli, the architecture changes, which could be considered the fourth dimension in the manufacturing process. Here, we briefly summarize manufacturing techniques, such as lithography and 3D printing, that can be used in fabricating complex structures based on the aforementioned principles. We then discuss the common architectures that have been developed using these methods, which include but are not limited to gripping, rolling, and folding structures. Then, we describe the biomedical applications of these structures, such as sensors, scaffolds, and minimally invasive medical devices. Finally, we discuss challenges and future directions in using shape-morphing materials to develop biomimetic and bioinspired designs.

“…However, microvascular anastomosis requires high skill level, resources, and cost, reducing its access substantially. Thus, a sutureless microvascular anastomosis alternative has potential to expand access of reconstructive surgery worldwide [ [1] , [2] , [3] ].…”

“…Vascular anastomosis is indispensable in numerous surgical operations, such as vascular bypass surgery and organ transplantation, and is often key to successful surgeries. [ 1 ] Although suturing has been successful in vascular anastomosis since 1902, it has various shortcomings. [ 2 ] First, needle penetration and stitch formation cause irreversible tissue damage, resulting in complications, such as intimal hyperplasia and thrombosis.…”

Less‐Suture Vascular Anastomosis: Development of Alternative Protocols with Multifunctional Self‐Wrapping, Transparent, Adhesive, and Elastic Biomaterials

Blood vessel anastomosis by suture is a life‐saving, yet time‐consuming and labor‐intensive operation. While suture‐less alternatives utilizing clips or related devices are developed to address these shortcomings, suture anastomosis is still overwhelmingly used in most cases. In this study, practical “less‐suture” strategies are proposed, rather than ideal “suture‐less” methods, to reflect real‐world clinical situations. In the case of rat artery (d = 0.64 mm) anastomosis, the less‐suture anastomosis involves the application of thin, adhesive, transparent, and self‐wrapping films to the site. This surprisingly reduces the number of stitches required from ten (without films) to four (with films), saving 27 min of operating time per vessel. Furthermore, the decreased number of stitches largely alleviates fibrosis‐mediated wall‐thickening. Thus, a less‐suture strategy is particularly useful for anastomosis of multiple vessels in emergency conditions and small‐diameter vessels.
