A new method for reconstructing rat uterine horn was developed in which nonpenetrating, arcuate-legged clips are applied in interrupted fashion to everted seromuscular edges, forming an elastomeric flanged joint. This anastomosis has unusual physical and morphologic properties, with improved tissue healing and luminal restitution. Clipping is easier than suturing, and resulted in equivalent fertility rate (50-60%) and litter size. It also is associated with less granuloma formation and hystiocytic infiltration than suture. The new technique has the potential of endoscopic translation for human tubal reconstruction.

Evolution of staples and clips for vascular anastomoses.
Int Surg

Department of Surgery, University Hospital Groningen, Groningen, The Netherlands.
Because of the development of less invasive surgical techniques, there is an increasing demand for vascular anastomosing techniques that require less exposure of the operating field. This paper reviews the most important representatives of staples, clips, and other mechanical devices for vascular anastomosing described over the last five decades. This report is organized in three parts: (1) the history of clipping and stapling devices, (2) development of the Vessel Closure System (VCS) clips, and (3) current and potential status of mechanical vascular anastomotic devices.

Purpose: To assess the durability of Vascular Closure System (VCS) clips for graft-artery and graft-graft anastomoses.
Methods: The subjects were 100 consecutive patients, who had undergone vascular procedures in which VCS clip application was attempted for anastomoses. The operative indications were arteriosclerosis obliterans in 69 patients, aortic aneurysm in 26, and other disorders in 5.

Non-penetrating, arcuate-legged titanium clips create an interrupted, non-penetrated, yet compliant vascular anastomoses that is associated with significantly reduced anastomotic neointimal hyperplasia. Recent experimental and clinical studies provide evidence that the non-suture alternative changes the biology of vessel-to-vessel and graft-to-vessel connections that reduces the stimulus for hyperplasia at a number of critical points in the response to injury schema. The compliant, "blood-tight" characteristics of clipped vascular reconstructions are associated with no endothelial injury or intraluminal foreign body, minimal platelet aggregation and laminal flow.

Non-penetrating, arcuate-legged titanium clips (VCS) have been utilized successfully over the past five years for a variety of cerebrovascular reconstructions. These applications, including both micro and macrovascular reconstructions, their clinical outcomes and technical considerations are described. Applications include patch angioplasty of cervical carotid endarterectomies, superficial temporal to middle cerebral artery 'bypass' procedures, Takayasu's arteritis and cavernous carotid reconstructions.
