PLATFORM DEVICE AND METHOD OF USE TO ASSIST IN ANASTOMOSIS FORMATION

摘要

There is described a platform device for use in forming an anastomosis and maintaining a desired curvature of a lumen in a desired shape during an anastomosis assistance period. The platform is formed from one or more bioabsorbable or biodegradable polymer filaments. There is also described a method for inserting a platform device for use in creation of an arteriovenous fistula by identifying a candidate artery and a candidate vein and dissecting the candidate vein. Next, inserting a platform device into the vein and creating a breach in the candidate artery at a desired angle and location. Next, introducing the platform device and vein into the candidate artery and forming the platform device into a curvature angle selected to minimize turbulent blood flow in an anastomosis formed by the vein and the artery. The platform may also be used to maintain potency of supply blood vessels and/or organ blood vessels or the lumens during an organ transplant procedure.

主权项

1. A platform device, comprising:
a bioabsorbable filament selected to begin degrading within one week of implantation into a lumen of a human or animal body and to be substantially completely absorbed by the animal or human body after an anastomosis assistance period has elapsed; and a coil structure having a length along a major axis and a width along a minor axis formed by a plurality of windings of the filament about the major axis wherein the filament width and the spacing between windings relates to the coil structure length and the dimension of the windings across the minor axis relates to the coil structure width.
