Abstract

A magnetic vascular clamp for vascular repair is described. There is a vascular sleeve forming a flexible cylindrical bellows that cylindrically encloses a section of vascular tissue to allow freely movement of the enclosed vascular tissue within the vascular sleeve. A pair of sleeve anchor rings are at each end of the vascular sleeve and they form a fixed seal with underlying vascular tissue to minimize fluid leakage from within the vascular clamp.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
         1 . A vascular clamp for vascular repair comprising:
 a vascular sleeve forming a flexible cylindrical bellows that cylindrically encloses a section of vascular tissue to allow freely movement of the enclosed vascular tissue within the vascular sleeve; and   a pair of sleeve anchor rings, one at each end of the vascular sleeve, forming a fixed seal with underlying vascular tissue to minimize fluid leakage from within the vascular clamp.   
     
     
         2 . A vascular clamp according to  claim 1 , wherein each sleeve anchor ring includes a plurality of sealing ribs for sealing with the underlying vascular tissue. 
     
     
         3 . A vascular clamp according to  claim 1 , wherein the vascular sleeve is made of polytetrafluoroethylene (PTFE) material.
