The present invention relates to a prosthesis based on a biocompatible textile and more particularly intended to be implanted by laparoscopy, such as, for example, the wall reinforcement prostheses for repair of hernias.
Wall reinforcement prostheses, for example for the abdominal wall, are widely used in surgery. These prostheses are intended to treat hernias by temporarily or permanently filling a tissue defect. These prostheses are generally made from a biocompatible prosthetic textile and can have a number of shapes, for example rectangular, circular or oval, depending on the anatomical structure to which they are to adapt. Some of these prostheses are made from entirely bioresorbable filaments and are intended to disappear after they have performed their reinforcing function during the period of cellular colonization and tissue rehabilitation. Others comprise non-bioresorbable filaments and are intended to remain permanently in the body of the patient.
Moreover, in order to minimize the trauma subsequent to any surgical intervention, patients are increasingly operated on by laparoscopy when the type of intervention performed allows this. Laparoscopy requires only very small incisions through which a trocar is passed, with the prosthesis being conveyed inside the trocar to the implantation site. Open surgery is thus avoided, and the patient can soon leave hospital. Laparoscopy is particularly popular in surgical interventions performed in the abdomen, for example the treatment of hernias.
However, the trocars used in laparoscopic surgery generally have a relatively small calibrated diameter, which may vary, for example, from 5 to 15 mm, in order to reduce as much as possible the size of the incision that is made. The prosthesis therefore has to be conveyed within a conduit of small diameter and must then be deployed at the implantation site.
To carry out this step, the prosthesis is generally rolled up on itself in order to make it slide in the conduit of the trocar or is introduced directly by force, if appropriate with the aid of laparoscopy forceps. However, the small diameter of the trocar used makes this step particularly difficult to carry out. If the rolling-up of the prosthesis is not correctly guided and effected, the textile may form a plug in the trocar. The prosthesis no longer slides inside the trocar, and it is very complicated to remove it from the latter. Moreover, even when the prosthesis has been correctly rolled up, the emergence of the prosthesis from the trocar and the deployment of the prosthesis at the implantation site are complex steps. Indeed, the surgeon initially has to pull on the prosthesis in order to free it from the trocar, but without damaging it. He then has to deploy the prosthesis and spread the latter out perfectly. If the prosthesis does not spread out perfectly against the abdominal wall for example, there may be a risk of a soft organ being inserted between the prosthesis and said wall, which can lead to risks of adherence, pain and intestinal occlusion and can increase the possibility of recurrence. It is therefore essential for the surgeon to ensure that no part of the prosthesis is folded and that no viscera or part of the intestine is caught between the prosthesis and the abdominal wall. However, on account of the limited space at the implantation site, it may prove complicated to deploy the prosthesis and then to orient it suitably with respect to the surrounding anatomical structures.
There is therefore still the need for a prosthesis that is based on a biocompatible textile, that can be used for the repair of hernias, that can be easily introduced into a conduit such as that of a trocar of small diameter, without damaging said textile, and that is able to be deployed completely, and preferably easily, once the implantation site in the body of the patient has been reached.
The present invention aims to meet such a need.
A first aspect of the invention concerns a prosthesis comprising:
In the present application, the longitudinal axis of a shape is understood as the axis aligned on the greatest dimension of said shape. In the case where said shape is a disc and does not have a greatest dimension, the longitudinal axis is a diameter of this disc.
In this application, the distal end of a device means the end farthest from the hand of the user, and the proximal end means the end nearest to the hand of the user. Likewise in this application, the term “distal direction” means the direction of introduction of the prosthesis into the body of the patient, and the term “proximal direction” means the direction opposite to this direction of introduction.
According to the present application, “textile” is understood as any arrangement or assembly of biocompatible yarns, fibres, filaments and/or multifilaments, for example obtained by knitting, weaving, braiding, or non-woven.
In the present application, “biocompatible” is understood as meaning that the materials having this property can be implanted in the human or animal body.
Within the meaning of the present application, a “flexible textile” is understood as a textile that can be folded up but that does not have an inherent elasticity allowing it to spontaneously recover a spread-out configuration once it has been folded up.
Within the meaning of the present application, a “semi-rigid structure” is understood as a structure having a rigidity that allows it to keep a textile spread out in the absence of any stress and to be gripped by instruments conventionally used in laparoscopic surgery, such as forceps, so as to be able to manipulate the textile, for example.
The prosthesis according to the invention is able to be easily gripped by a part of a tool conventionally used in laparoscopic surgery, for example by at least one of the jaws of a pair of forceps, and to be then introduced into a trocar by a simple distal movement towards the proximal entrance of the trocar, without first having to fold the prosthesis. The nature and the arrangement of the reinforcing element, provided with a fastening element at the distal end thereof, cause automatic folding along one or more longitudinal folds when, for example, a jaw of the forceps is engaged in the fastening element and the prosthesis is then transported towards the trocar. The forceps are then introduced into the proximal entrance of the trocar and pushed towards the distal end of the trocar. During this movement, the prosthesis is forced automatically to fold up along one or more longitudinal folds and, coupled to the forceps, it enters the trocar without difficulty. The prosthesis according to the invention could also be pushed into the trocar directly by hand by the surgeon, then by laparoscopy forceps in order to complete the introduction of the prosthesis into the abdomen of the patient, for example.
Thus, the prosthesis is able to adopt an elongate configuration, substantially aligned on its longitudinal axis A and very compact in the radial direction, allowing it to pass through a trocar without difficulty. The prosthesis can thus be folded in order to enter a trocar of small diameter, for example a diameter of 5 to 15 mm.
When the prosthesis emerges from the trocar, the surgeon can make use of the reinforcing element to deploy the prosthesis and return the latter to its initial spread-out configuration. The prosthesis is capable of conforming to the anatomical structures and of remaining in place once it has emerged from the trocar.
The textile of the prosthesis according to the invention can have any shape. The textile can have the shape of a disc, in which case one of its diameters defines the longitudinal axis A of the textile. In one embodiment, the textile has a generally elongate shape, for example a rectangular, oval or elliptic shape, defining a longitudinal axis A. The textile can have another initial shape and can then be cut to such an elongate shape, in particular to a shape adapted to the defect, for example the hernia defect, that is to be treated.
In one embodiment, said generally elongate shape is a rectangle. In another embodiment, said generally elongate shape is an ellipse. Such shapes are particularly advantageous, since they are similar to the anatomical shape of the defect that is to be filled. Moreover, such prostheses can adopt a compact shape that is substantially aligned on their longitudinal axis, permitting easy introduction into a trocar, even one of small diameter.
In one embodiment, the textile is a mesh.
Within the meaning of the present application, a “mesh” is understood as a textile, as defined above, which is openworked, that is to say provided with pores that favour recolonization of tissue. Such a mesh can be bioresorbable, permanent or partially bioresorbable. It is sufficiently flexible to be folded up at the time of introduction of the prosthesis into the trocar. Such meshes are well known to a person skilled in the art.
In one embodiment of the invention, the mesh is a knit. By virtue of the meshwork of the knit, it is possible to obtain openworked faces that promote cell recolonization after implantation. The knit can be two-dimensional or three-dimensional.
Within the meaning of the present application, a two-dimensional knit is understood as a knit having two opposite faces linked to each other by meshes but devoid of a spacer giving it a certain thickness: such a knit can be obtained, for example, by knitting yarns on a warp knitting machine or raschel knitting machine using two guide bars. Examples of knitting two-dimensional knits suitable for the present invention are given in the document WO2009/071998.
According to the present application, a three-dimensional knit is understood as a knit having two opposite faces linked to each other by a spacer that gives the knit a significant thickness, said spacer itself being formed from additional linking yarns in addition to the yarns forming the two faces of the knit. Such a knit can be obtained, for example, on a double-bed warp knitting or raschel knitting machine using several guide bars. Examples of knitting three-dimensional knits suitable for the present invention are given in the documents WO99/05990, WO2009/031035 and WO2009/071998.
The reinforcing element comprises at least one semi-rigid elongate structure connected to the textile, said structure being substantially parallel to said longitudinal axis A.
The materials that may be suitable for producing the reinforcing element, in particular said structure, of the prosthesis according to the invention may be chosen from any biocompatible material having a certain rigidity in order to meet the requirements described above.
In one embodiment, said reinforcing element is made of bioresorbable material. In the present application, “bioresorbable” or “biodegradable” is understood to mean that the materials having this property are absorbed and/or degraded by the tissues or washed from the implantation site and disappear in vivo after a certain time, which may vary, for example, from a few hours to a few months, depending on the chemical nature of the materials.
Thus, the reinforcing element acts as a guide for the prosthesis for introducing the latter into a trocar, then acts as a means of stiffening the prosthesis during the positioning and implanting of the prosthesis, after which it gradually degrades, for example when the prosthesis has been fixed or when the textile has been recolonized by the surrounding cells.
For example, the bioresorbable material can be chosen from among polylactic acid (PLA), polycaprolactones (PCL), polydioxanones (PDO), trimethylene carbonates (TMC), polyvinyl alcohol (PVA), polyhydroxyalkanoates (PHA), oxidized cellulose, polyglycolic acid (PGA), copolymers of these materials and mixtures thereof. For example, the bioresorbable material can be a copolymer of polylactic acid and of polyglycolic acid.
Alternatively, the reinforcing element of the prosthesis according to the invention is made of a non-bioresorbable material chosen from among polypropylenes, polyesters such as polyethylene terephthalates, polyamides, silicones, polyether ether ketone (PEEK), polyarylether ether ketone (PAEK), polyurethanes and mixtures thereof.
In another embodiment, the reinforcing element is formed by a combination of bioresorbable material and of non-bioresorbable material.
The reinforcing element, in particular said structure, of the prosthesis according to the invention is connected to said textile. For example, the reinforcing element can be fixed to the textile by sewing, ultrasonic welding, or else by adhesive bonding or moulding.
In one embodiment, the reinforcing element of the prosthesis according to the invention is moulded over the textile. Thus, the reinforcing element is connected to the textile by injection moulding of one or more thermoplastic or thermosetting biocompatible materials. For example, the mould of an injection-moulding machine is equipped with an insert gate in which the textile is held. One or more thermoplastic or thermosetting biocompatible materials are then heated to their melting point and injected into the mould, the latter having one or more channels of the shape desired for the reinforcing element. The holding of the textile, the precision of the injection volume and the choice of the injection parameters make it possible to obtain a reinforcing element without material loss, without flash and with good surface evenness. Such a method allows the reinforcing element to be fixed to the textile in a particularly effective and lasting way.
In one embodiment, the reinforcing element is obtained by moulding a copolymer of polylactic acid and of polyglycolic acid over the textile.
The semi-rigid elongate structure of the reinforcing element of the prosthesis according to the invention has a distal end provided with at least one fastening element distinct from said textile.
The fastening element of the prosthesis according to the invention is capable of cooperating with a part of a tool that is able to pass through said trocar, in order to temporarily couple said prosthesis to said tool. Thus, the fastening element can have any shape suitable for the engagement of a part of a tool that is able to pass through a trocar. For example, with the tool being intended to carry the prosthesis along with it in the distal direction, the fastening element can have any shape allowing an element, for example a projecting element, of the tool to be engaged in the fastening element when the tool is brought towards the fastening element by a distal movement.
The fastening element is preferably dimensioned so as to be able to receive a projecting element of a laparoscopy tool, for example a jaw of a pair of forceps, that can pass through a trocar of small diameter, for example a diameter of 10-15 mm, and also so as to be able itself to pass easily through the trocar when provided with the prosthesis. Thus, for example, for use of the prosthesis according to the invention with a trocar having an internal diameter of 15 mm, the fastening element has outer dimensions smaller than a circle with a diameter of 15 mm, preferably smaller than a circle with a diameter of 5 mm.
The present invention thus relates to a prosthesis comprising:
The fastening element is distinct from the textile. Thus, when the tool is engaged in the fastening element, said tool is not in contact with the textile, and the risks of the textile being damaged, for example by being caught by a projecting part of the tool, are avoided. Therefore, the integrity of the structure of the textile, in particular its openworked structure for example, is not affected when the tool is coupled to the prosthesis.
In one embodiment, the fastening element has the shape of a closed ring. Thus, for example, a jaw of a pair of forceps for a trocar can be easily engaged in said ring. This engagement makes it possible to couple the prosthesis to the forceps and to introduce the prosthesis into the trocar at the same time as the forceps, for example once the two jaws have been closed on each other.
In one embodiment, said fastening element has the shape of an open ring, the opening in the ring being situated substantially in the proximal region of the ring. Thus, when a part of the tool, for example a projecting element such as the jaw of a pair of forceps, approaches the fastening element via a distal movement with respect to the prosthesis, it can be engaged in the open ring. When the user continues the distal movement of the tool with respect to the prosthesis, the jaw engaged in the open ring comes into abutment against the non-open part of the ring, and the prosthesis is thereby coupled to the tool and is carried along with the tool in the distal direction.
In one embodiment, said structure comprises at least one rod segment extending parallel to the longitudinal axis A. Thus, during the introduction of the prosthesis into the trocar, the rod segment serves as a guide for the natural folding of the textile of the prosthesis along one or more longitudinal folds parallel to the rod segment.
In one embodiment, the reinforcing element comprises several of said structures parallel to one another, each being provided, at the distal end thereof, with a said fastening element. For example, said fastening elements are aligned along a line transverse to said longitudinal axis A. The surgeon can thus successively engage the different fastening elements with the same jaw of a pair of forceps, thereby obtaining a first folding of the textile along one or more longitudinal folds, before introducing the prosthesis into the trocar.
In one embodiment, said structure additionally comprises one or more oblique rod segments configured to promote the folding of the textile along one or more longitudinal folds when the textile is subjected to a radial pressure in the direction of its longitudinal axis A. For example, the oblique rod segments can be situated generally in a proximal region of the textile and can form an angle of 0 to 50.degree. with the longitudinal axis A, converging towards a rod segment parallel to the longitudinal axis situated in a distal region of the textile. Such an elongate structure allows the prosthesis to be folded up gradually as it enters the trocar, the two oblique rod segments serving as a guide for the textile as it folds up inside the trocar when the textile is subjected to the radial pressure acting in the direction of its longitudinal axis A and exerted by the walls of the trocar.
In one embodiment, the prosthesis additionally comprises an indicator of a defined location of the textile. For example, the prosthesis can comprise an indicator of the centre of the textile. The centre of the textile can be the centre of the prosthesis. Such an indicator can help the surgeon when placing the prosthesis in the implantation site, the visibility at such a site generally being reduced and/or obstructed by the presence of the surrounding organs. Such an indicator can be in the form of a geometric figure. In one embodiment, said indicator forms a part of said elongate structure.
In one embodiment, the prosthesis comprises a means of information concerning the orientation of the prosthesis. Thus, at the implantation site where the visibility is reduced, the surgeon can have information concerning the longitudinal or transverse direction of the prosthesis. In one embodiment, said means of information forms a part of said elongate structure.
In one embodiment of the invention, one face of the textile is covered by a non-stick coating.
Such a non-stick coating makes it possible in particular to avoid the formation of undesired and serious post-surgical fibrous adhesions.
Within the meaning of the present application, “non-stick” is understood as a smooth and non-porous biocompatible material or coating that does not offer space for cell recolonization and that preferably promotes the growth of new peritoneum.
Another aspect of the present invention is a method by which a prosthesis of the kind described above is conveyed to an implantation site, said method comprising the following steps:
The prosthesis is thus pushed along the longitudinal axis of the trocar until its end, along with said tool, emerges from the trocar via the distal orifice thereof.
The push is continued until the whole prosthesis has emerged completely from the trocar.
By virtue of the structure of the prosthesis according to the invention, the step of introducing the prosthesis into the trocar is greatly facilitated. Likewise, with the prosthesis folding up automatically into a compact configuration as it penetrates into the proximal orifice of the trocar, it passes through the trocar easily and without damage.
Finally, the prosthesis is returned to its spread-out configuration at the implantation site by the surgeon unfolding the prosthesis. To do this, the surgeon can make use of the reinforcing element, which allows the unfolded prosthesis to be maintained in a spread-out state in the absence of any external stress.
The advantages of the present invention will become clearer from the following detailed description and from the attached drawings in which:
As will be seen from
Referring to
In other embodiments, the textile 2 could have an oval shape, or an elliptic shape, or be protean.
The textile 2 is made up of an arrangement of biocompatible filaments, such as a knit, a woven or a nonwoven. Preferably, as is shown in
The textile 2 can be bioresorbable, permanent or partially bioresorbable. As will become clear from the description below, the textile 2 is sufficiently flexible to be folded up, in particular at the time of introduction of the prosthesis into a trocar, along one or more longitudinal folds. In general, however, the textile 2 does not have an inherent elasticity allowing it to spontaneously recover a spread-out configuration once it has been folded up. The textile 2 can be supplied in the form of a band, which one cuts to the dimensions of the defect to be treated.
Referring again to
The elongate structures 8, in particular the rod segments 3, are connected to the textile 2. They can be attached to the textile 2 by means of a seam, or else by means of an ultrasonic weld, by adhesive bonding, or by injection moulding.
In one embodiment, the rod segments 3 are joined to the textile by means of injection moulding. Such an embodiment makes it possible to secure the fixing of the rod segments 3 to the textile 2 in a particularly effective manner and to produce the prostheses according to the invention at an industrial scale.
In the technique of injection moulding, a mould is formed in which, for example with reference to the example shown in
After the injection step, the mould is opened and the prosthesis 1 is withdrawn from the mould. Such a method allows the textile to be “embedded” in the part moulded over it. Thus, the rod segments 3, which are the overmoulded parts, are connected to the textile 2, without any risk of their coming loose or fragmenting.
On account of the nature and the structure of the rod segments 3, the latter act as guides for introducing the prosthesis 1 into a small orifice, such as an admission orifice of a trocar, as will become clear from the description below.
Thus, in order to easily introduce the prosthesis 1 of
In the example shown, the fastening element is a closed ring 4. It is clear from
The ring 4 is dimensioned so as to be able to receive a jaw of a pair of forceps, that can pass through a trocar of small diameter, for example a diameter of 5-15 mm, and also so as to be able itself to pass easily through the trocar. Thus, for example, for using the prosthesis according to the invention with a trocar having an internal diameter of 5-15 mm, the ring 4 has an external diameter of less than 10 mm, for example of approximately 5 mm.
The fastening element, i.e. the closed ring 4 in the example shown, is distinct from the textile 2. The ring 4 is not moulded on the textile 2. This is because the ring 4 has to be able to receive a projecting element of a tool for laparoscopic surgery, in order to be able to couple the prosthesis to said tool, but said projecting element must not engage the textile 2 itself. Thus, when the tool is engaged in the ring 4, said tool is not in contact with the textile 2, and the risks of the textile 2 being damaged, for example by being caught by a projecting part of the tool, are avoided. Therefore, the integrity of the structure of the textile, in particular its openworked structure when the textile is a mesh for example, is not affected when the tool is coupled to the prosthesis.
Referring to
Thus, when a user moves the forceps 10 in the distal direction symbolized by the arrow F in
The prosthesis 1 is then ready to be positioned opposite a hernia defect that is to be treated. During the positioning of the prosthesis 1, the latter can be easily manipulated by means of tools conventionally used in laparoscopic surgery, these tools being able, among other things, to take hold of all or some of the elongate structures 8.
In this embodiment, the reinforcing element comprises a semi-rigid elongate structure 8 comprising a rod segment 3, which is generally aligned on the longitudinal axis A and which is provided with a fastening element in the form of a closed ring 4 at the distal end 3a thereof. The rod segment 3 is situated in the distal region of the textile 2 and, therefore, of the prosthesis 1. The structure 8 additionally comprises two oblique rod segments 6, which each form an angle .alpha. with the longitudinal axis A and are generally situated proximally with respect to the proximal end of the rod segment 3. Finally, the elongate structure 8 also comprises a triangular frame 7 extending in the longitudinal direction and arranged between the rod segment 3 and the oblique rod segments 6. Such a shape of the structure 8 facilitates the automatic folding of the textile 2 along longitudinal folds at the moment when the textile 2, coupled to trocar forceps, is introduced into a trocar.
Furthermore, the triangular frame 7 forms an indicator of the centre of the textile 2 and also a means of information concerning the orientation of the prosthesis 1. This is because the triangular frame 7 itself is of elongate shape and indicates to the surgeon the longitudinal direction of the prosthesis 1. Finally, the short side of the triangular frame 7 indicates the proximal direction, while the angle opposite this short side indicates to the surgeon the distal direction. Such an indicator of a defined location of the textile and a such means of information concerning the prosthesis are particularly useful to the surgeon when the prosthesis 1 has reached the implantation site, where the field of view is reduced and/or obstructed by the presence of the surrounding organs.
The prosthesis according to the invention can thus be easily introduced into a trocar, without any risk of forming a plug inside the trocar. By virtue of its nature and its structure, the reinforcing element of the prosthesis according to the invention stiffens the prosthesis and serves as an element for guiding and transporting the prosthesis inside a trocar conduit of particularly small diameter, such as a diameter of 5-15 mm. The reinforcing element, by stiffening the textile of the prosthesis, also serves to spread the prosthesis out at the moment when the latter emerges from the trocar at the implantation site.
