Definitions

  • Anastomosis is performed for the purpose of connecting different conduits together to optimize or redirect flow
  • anastomosis is done to bypass the occluded vessel by harvesting a portion of an unobstructed vessel and joining it to the occluded vessel below the point of stenosis
  • the common procedure for performing the anastomosis during bypass surgery requires the use of very small sutures, loupes and rracrosurgical techniques Surgeons must delicately sew the vessels together being careful not to suture too tight and tear the delicate tissue, thereby destroying the vessel
  • Long term patency of anastomosis is also an issue Exposure of damaged vessel wall to the bloodstream can lead to formation of thrombus and possible occlusion of the artery As cardiac
  • anastomosing blood vessels may involve nsks of physical inju ⁇ es to the patient
  • CABG coronary artery bypass grafting
  • anastomosis often requires manipulation of the heart, so surgeons may access the back of the heart as well as the front Patients supported by cardiopulmonary bypass during the procedure nsk post-surgical complications that vary directly with the duration for which the heart is under cardioplegic arrest
  • surgeons performing anastomosis on a beating heart nsk the possibility of a hemodynamic compromise during longer procedures Consequently, surgeons are constantly searching for techniques to both reduce the nsk of tissue damage as well as the laborious and time-consuming task of vessel suturing
  • Figure 1 is a perspective view of a simple embodiment of the invention where two partial cylrndncal segments are interconnected along the periphery of an opening,
  • Figure 2 shows the embodiment of Figure 1 inserted within two vessels thereby interconnecting those vessels
  • Figure 3 shows an alternative embodiment of the device of the invention where full
  • Figure 5 shows an alternative embodiment of the invention where the first and second segments are connected in a manner such that each segment is at a right angle or perpendicular to the other segment
  • Figure 6 includes Figures 6A, 6B and 6C each of which show embodiments of the device being delivered by a surgical dispenser and inserted into a vessel with Figure 6A showing the device almost completely inserted within the surgical dispenser lumen, Figure 6B showing the device partially extruded from the surgical dispenser lumen and Figure 6C showing the device completely extruded,
  • Figure 7 includes Figures 7A. 7B. 7C. 7D and 7E each of which show a step of an alternative embodiment of putting the device of the invention in place using a catheter and guidewire with Figure 7A showing the device within the catheter and a guidewire in place, Figure 7B showing the device moved toward the opening in the vessel guided by the guidewire, Figure 7C showing the device partially inserted, Figure 7D showing the device completely inserted into two vessels thereby interconnecting those vessels and Figure 7E showing the catheter withdrawn,
  • An object of the invention is to provide a device for interconnecting two vessels within a patient — which device is configured so as to be easily inserted into an opening in a vessel and allow for a flow of matenal through the vessel after insertion
  • Another object of the invention is to provide for a method of quickly and efficiently performing an anastomosis
