Definitions

  • This invention relates to medical apparatus and procedures, and more particularly to artificial medical graft methods and apparatus.
  • Tubular artificial grafts are needed in various medical procedures. For example, such grafts may be needed to replace diseased or damaged sections of natural tubular body tissue such as in the circulatory system, the urinary tract, etc. Or such grafts may be needed to make new connections in natural tubular body tissue systems such as bypass or shunt connections in the circulatory system. An artificial tubular graft may be needed as either a temporary or permanent installation.
  • FIG. 1 is a simplified elevational view of an illustrative embodiment of an artificial graft and illustrative apparatus useful in installing the graft, all in accordance with this invention.
  • FIG. 1 shows the graft being installed between the ends of two sections of natural body tissue tubing.
  • FIG. 2 is a simplified elevational view of an illustrative embodiment of a portion of the apparatus shown in FIG. 1.
  • FIG. 3 is a view similar to FIG. 1 showing the installed graft.
  • FIG. 4 is a simplified end view of an illustrative embodiment of a portion of the apparatus shown in FIG. 3.
  • FIG. 5 is a simplified end view of another illustrative embodiment of a portion of the apparatus shown in FIG. 3.
  • FIG. 6 is an elevational view of a structure that can be used to make a particular embodiment of the apparatus portion shown in FIG. 4.
  • FIG. 7 is a simplified elevational view of a subsequent condition of the FIG. 6 structure during fabrication.
  • FIG. 8 is another view generally similar to
  • FIG. 1 but showing another illustrative embodiment of the invention.
  • FIG. 9 is a view similar to FIG. 8 showing a later stage in use of the FIG. 8 apparatus.
  • artificial tubular graft 20 is being installed between the ends of two sections 10a and 10b of natural body tissue tubing in a patient.
  • the purpose of graft 20 may be to replace a diseased or damaged portion of the patient's body tissue tubing that has been removed.
  • Tubing 10 may be circulatory system tubing or any other body tissue tubing that is suitable for use with graft 20.
  • any suitable construction can be used for the main portion of graft 20, a particularly preferred construction is shown and described in Goldsteen et al .
  • this graft construction may include a tubular mesh framework 22 of nitinol covered with silicone 24 to substantially fill in the interstices in the framework. Additional details, features, and alternatives regarding this type of graft construction will be found in the above-mentioned Goldsteen et al . reference, and in Bachinski et al .
  • each axial end portion of graft 20 includes a radially enlargeable connector structure 30.
  • each connector structure 30 is self-expanding.
  • each connector structure 30 is an elastic, annular structure which is resiliently biased to return to a radially enlarged size that is preferably at least as large as (and more preferably somewhat larger than) the body tissue tube opening to which that end portion of the graft will be attached. Initially, however, each connector structure 30 is radially compressed to a substantially smaller size as shown in FIG. 1. This allows each axial end portion of graft 20 to be easily inserted (as shown in FIG. 1) into the body tissue tubing 10 to which that end portion of the graft is to be attached.
  • each connector structure 30 includes a clip portion 52 and a release portion 54 (see also FIG. 2) .
  • each clip structure 50 may be made of stainless steel, with the clip portion 52 being strong enough to radially compress the associated connector structure 30.
  • the release portion 54 of either clip structure 50 is pulled radially out from graft 20
  • the C-shaped clip portion 52 of that clip structure comes off the associated connector structure 30.
  • This firm contact provides a fluid-tight seal between body tissue 10 and graft 20, as well as secure mechanical attachment of the graft to the tissue.
  • each connector structure 30 may be initially radially compressed by a wire wrapped around the connector structure.
  • the wire is unwrapped from that structure.

Rings 32 may be formed to press substantially uniformly out against the inner surface of body tissue tubing 10 all the way around the circumference of the graft. Alternatively, rings 32 may be formed with circumferentially spaced "high spots” or "pressure points" 34 (see FIG. 4) which locally bear somewhat more strongly on the inner surface of body tissue tubing 10. Such localized points 34 of higher bearing pressure and therefore greater indentation of body tissue tubing 10 can help ensure that the end portion of the graft does not slip out of the body tubing after the graft has been installed.
  • a metal e.g., nitinol
  • covering 24 e.g., of silicone
  • connector structures 30 may additionally include structures 36 (see FIG. 5) which radially penetrate the adjacent body tissue tubing 10. If such tissue-piercing structures 36 are provided, they may be substantially straight prongs or struts, curved hooks, or any other suitably shaped members. If provided, structures 36 may be sharply pointed to facilitate tissue penetration, and they may be barbed (e.g., like fishing hooks) to substantially prevent them from coming out of the tissue they have pierced.
  • a particularly preferred way of producing a serpentine ring 32 with the above-described high spots 34 is to start with a short length of thin-walled metal tubing 60 as shown in FIG. 6 and cut away interdigitated portions 62 from opposite axial ends of the tube as shown in FIG. 7.

  • Each of apertures 126 may be provided with a purse string suture 128 or other functionally equivalent structure for use in closing the aperture when desired.
  • Balloons 140 are initially uninflated so that connector structures 130 can be initially radially relatively small as shown in FIG. 8. As in the case of FIG. 1, the initially relatively small radial size of connector structures 130 facilitates their insertion in the body tissue tubing 10a and 10b to which graft 120 is to be attached.

Then tubes 142 and balloons 140 are withdrawn from graft 120 via apertures 126. After apertures 126 have thus been cleared, apertures 126 are closed (e.g., by tightening and securing purse string sutures 128). Except for the addition of closed apertures 126, the appearance of finished and fully installed graft 120 may be substantially as shown for graft 20 in FIG. 3.
  • Grafts 20/120 are preferably made up in a range of sizes (e.g., lengths and diameters) so that they are available for various patient applications. Grafts 20/120 may also be made in a variety of shapes, and these various shapes may also be made in a range of sizes. For example, grafts 20/120 may be made in curved shapes, Y shapes, T shapes, etc. In the case of shapes with more than two ports (e.g., Y or T shapes with three ports) , each port is provided with a connector structure 30/130 for attachment of that port to body tissue of the patient.

Abstract

L'invention porte sur une greffe artificielle destinée à être fixée sur un tissu biologique du corps d'un patient, ce tissu présentant au départ une structure de connexion radiale relativement petite, adjacente à chacune de ses extrémités. La taille initiale relativement petite de chaque structure de connexion facilite l'insertion de cette partie de la greffe dans le tissu biologique sur lequel cette structure doit faire un raccordement. Après avoir correctement positionné ladite structure par rapport au tissu biologique, celle-ci s'agrandit radialement pour raccorder la greffe au tissu biologique. Le raccordement est de préférence à la fois un raccordement mécanique et étanche aux fluides.
