  • Patent number: 9017348
    Abstract: An insufflable prosthesis is provided, that is radiopaque or with a circumferential radiopaque mark, for sutureless and non clamping side-to-side, end-to-end and end-to-side anastomosis, or fast clamping and sutureless wherein vessel graft or any other is inserted or not (whether externally covered or not if using grafts), in the lumen of the prosthesis comprised by an insufflable balloon, whether distensible or not and after being covered by graft, the balloon can be filled with polymerizable fluid, like silicon or cyanoacrylate glue, whether radiopaque or not, by a syringe having unidirectional valve to a needed caliber in order to keep the graft wall jointed and tight in relation to the organ which performs the anastomosis. The insufflable balloon, elastic and distensible, or non elastic and having preset dimensions also comprises non elastic punctiform bars inside that are responsible for keeping constant the distance between the elastic balloon walls.

  • Publication number: 20110172684
    Abstract: Prosthetic devices are provided that are used for end-to-side, end-to-end and side-to-side anastomosis, without clamping and sutureless or with quick clamping and sutureless, where the tubular member of the prosthesis, besides having its intraluminal part angled in relation to the flange, can also have more than one intraluminal part, in form of a “Y”, a “T”, and other variations. The flange can also be with or without openings or small handles and chamfers, allowing the tie-up to the external part of the tissue, vein, artery or tubular organ to eliminate the contact of foreign bodies inside the anastomosis. The prosthesis can also be without flange or have a tubular member with tapered center to peripheral part or from external part to intraluminal one, and it can be cut in the desired size and gauge. Therefore, the prosthesis can have varied sizes and shapes to accommodate varied graft sizes and types in a simultaneous way.

  • Publication number: 20100318109
    Abstract: Prosthetic devices are provided that are used in end-to-side, end-to-end, and side-to-side anastomosis without clamping and sutureless, or with clamping and sutureless, where the graft is inserted in at least one of the intraluminal parts of the tubular member of the prosthesis, and is everted and coated, being previously fixed to the flange. The tubular member and flange are screwed among them in order to make the size of the intraluminal part more flexible.

  • Publication number: 20100191263
    Abstract: Prosthetic devices are provided for laparoscopic anastomosis, of end-to-side, end-to-end and side-to-side, with clamping and sutureless or with quick clamping and sutureless, where a prosthesis of large caliber can be introduced in the inner of the cavity where the anastomosis will be done passing through trocars of small caliber. When the prosthesis has intraluminal part, this will be covered by the grafts avoiding the contact of fluids which flow with the prosthesis material and with the anastomosis threads. The flange or the intraluminal part can also have openings or small straps allowing the fixation of the prosthesis to the external part of the tissue, vein, artery or tubular organ to eliminate the contact of foreign bodies with the inner of the anastomosis.

  • Patent number: 6503258
    Abstract: The present invention 10 discloses a prosthetic device used for end to side, end to end, and side to side anastomosis without clamping and suture or without suture but with clamping wherein the graft is inserted into the lumen 17 of the tubular member 18 of the prosthesis having a diameter approximately equal to the inside diameter of the tubular member 18 of the prosthesis for end to end and end to side anastomosis and can be everted 28 to cover that part of the prosthesis that will reside within the vein, artery or other tubular organ 12 and affixed to the base of the prosthesis by a circular suture 30. The tubular member 18 of the prosthesis 10 is attached to a base flange member 16 having apertures 24 therein which allow the flange 16 to be stitched to the outside of the aorta or other tubular organ 12 to eliminate the introduction of foreign bodies into the lumen of the anastomosis.
