This application claims priority from U.S. provisional patent application Ser. No. 60/901,457 filed on Feb. 14, 2007; U.S. provisional patent application Ser. No. 60/921,930, filed on Apr. 5, 2007; and U.S. provisional patent application Ser. No. 61/015,258, filed on Dec. 20, 2007, the disclosures of which are hereby incorporated herein by reference in their entireties.

BACKGROUND OF THE INVENTION

The present invention is directed to an implantable medical device and a method of affixing an implantable medical device. The invention has application to gastrointestinal devices and to other devices that are implanted in a patient's hollow organ or cavity that is accessible through a natural orifice.

Medical devices often require fixation in patients, whether the device is intended to be in place temporarily, permanently, or semi-permanently. Fixation often needs to be strong, particularly where the device experiences a shear force, such as in the presence of peristalsis. However, fixation to the wall of certain hollow organs or cavities may be difficult due to, for example, localized tension applied to the wall. As a result, attachment could fail or lead to ulceration, or the like. SUMMARY OF THE INVENTION

An implantable medical device and method of implanting a medical device in a hollow organ or cavity lined with the mucosa, according to an aspect of the invention, includes providing a medical device having a wall configured to the size and shape of a portion of a cavity or hollow organ lined with the mucosa. At least one opening is provided in the wall that is large enough to receive a section of the mucosa extending in the opening. The wall is positioned against the portion of the cavity or hollow organ thereby receiving the section of the mucosa within the opening.

The device may include a retainer that retains the section of the mucosa within the at least one opening while maintaining perfusion of the section of the mucosa. The retainer may include a penetrating component, a pressure component, or both. Such penetrating component is adapted to penetrate the section of the mucosa in the at least one opening. Such pressure component is adapted to put pressure on the section of the mucosa in the at least one opening. The wall of the device may have an outer surface and an inner surface, with the inner surface defining a lumen. The retainer may be accessible from within the lumen to detach the wall from the mucosa.

The at least one opening may be a plurality of openings and the penetrating component may include a plurality of penetrating components, one for retaining the section of the mucosa within each of the openings. Alternatively, the penetrating component may include an elongated member that penetrates the sections of the mucosa at the plurality of openings. The elongated member may be a suture, a needle, or the like.

The at least one opening may be defined between two moveable portions of the wall, wherein the pressure component is made up of moveable portions being adapted to move together. A penetrating component may be provided at one of the moveable portions and extending into the at least one opening. The penetrating component may be made up of a plurality of pointed members extending into the at least one opening from at least one of said moveable portions. The wall may be in a generally tubular shape and the opening may span the length of the wall in the direction of an axis of the tubular shape.

The at least one opening may include at least two of openings that are closely spaced and the retainer may retain the sections of the mucosa bridging the at least two openings. The retainer may include a clip, a fusion agent, such as a sclerosant, or the like.

The retainer may include a fibrotic tissue response inducing material at least partially surrounding the at least one opening.

The retainer may be made at least in part from a bioabsorbable material or from a non-absorbable material.

The wall may be a generally impervious surface having a surface area that is larger than an area of the at least one opening. The at least one opening may have a width or diameter that is at least on an order of magnitude of 1 millimeter.

The device may be an esophageal stent, a bariatric device, an anti-reflux device, a nasal gastric tube, an intestinal sleeve, or the like. These and other objects, advantages and features of this invention will become apparent upon review of the following specification in conj unction with the drawings.

DESCRIPTION OF THE PREFERRED EMBODIMENT Referring now specifically to the drawings, and the illustrative embodiments depicted therein, a medical device 12 includes a wall 18 configured to the size and shape of a portion of a cavity or hollow organ lined with the mucosa and a fixation mechanism 60 that is adapted to fix wall 18 with the portion of the cavity or hollow organ (Figs. 1 through 3). The fixation mechanism may include one or more openings 62 in wall 18 that are large enough to receive a section of the mucosa extending into the opening. Because of an interference fit between wall 18 and the portion of the cavity or hollow organ, the mucosa tends to bulge into opening(s) 62. Once the mucosa has entered the openings, the medical device should remain anchored until it is intentionally removed. Fixation mechanism 60 may be used to resist shear force, such as that created by peristalsis and thereby functions as an anti- migration mechanism. In the illustrated embodiments, the portion of wall 18 that does not include opening(s) 62 is a generally impervious surface having a surface area that is larger than an area of opening(s) 62. This reduces tendency for erosions of the mucosa and formation of ulcers. Also, in the illustrated embodiments, capture of the mucosa is limited to the areas at opening(s) 62 thus making removal of the medical device easier. In the illustrative embodiment, opening(s) 62 has a diameter or width that is at least on an order of magnitude of 1.0 mm or greater to receive a sufficiently large bulge of mucosa to provide fixation. It should be understood that the term mucosa is intended to include submucosa. Also, it should be understood that the tissue bulging into opening(s) 62 may include muscularis and serosa as well as mucosa.

In the illustrative embodiments, medical device 12 is shown as an esophageal stent. However, the illustrated techniques may be applied to a bariatric device of the type disclosed in International Publication No. WO 2006/044640 Al and in United States patent application Serial Nos. 60/901,457 filed on February 14, 2007, and 60/921,930 filed on April 5, 2007, by Baker et al. for a BARIATRIC DEVICE AND METHOD, the disclosures of which are hereby incorporated herein by reference in their entirety. The medical device may also be an anti-reflux device, a nasal gastric tube, an intestinal sleeve, other gastrointestinal device or other such medical device as is known in the art.

A retainer 66 may be provided to retain the section of the mucosa within opening(s) 62. Retainer 66 retains the section of the mucosa within opcning(s) 62 while maintaining perfusion of the mucosa. Retainer 66 may have a penetrating component which penetrates the mucosa to help retain the section of the mucosa within opening(s) 62. Retainer 66 may have a pressure component which puts pressure on the section of the mucosa to help retain the section of the mucosa within opening(s) 62. The pressure component applies sufficient pressure to retain the section of the mucosa, but not enough pressure to cause ischemia which can lead to necrosis. It should be understood that retainer 66 may include a penetrating component, a pressure component, or both.

Wall 18 has an outer surface 20 and an inner surface 19. Inner surface 19 may define a lumen 63. Retainer 66 may be accessible from within lumen 63 to detach wall 18 from the mucosa in a manner that will be described in more detail below. This facilitates placement and removal of the medical device through a natural orifice, such as endoscopically, or the like. Opening 62 may be a plurality of openings, each of which is large enough to receive a section of the mucosa extending into the opening. Retainer 66 may be used with fixation mechanism 60 (Fig. 2). Retainer 66 includes a penetration component having a base 68 and a plurality of elongated members, such as needles or tines 67 that interconnects the sections of the mucosa at said plurality of openings. Retainer 66 may be formed to the size and shape of lumen 63 with needles 67 arranged to correspond to positions of openings 62. This allows the physician to first position medical device 12 in the hollow organ or cavity, with wall 18 configured to press against the surface of the organ or cavity thereby causing the mucosa to bulge through openings 62. Retainer 66 can then be moved axially along lumen 63 with needles 67 penetrating the mucosa extending through each opening. This will not significantly interfere with perfusion of the mucosa. When it is desired to remove the medical device, retainer 66 is removed from within lumen 63. Any remaining mucosa can be removed, if desired, by ablation and the medical device moved or removed.

Fixation mechanism 60 may further include retainer 66' in the form of material surrounding opening 62 that causes a fibrotic tissue response in the mucosa extending through the opening (Fig. 3). While retainer 66' may take awhile to assist in retaining the section of the mucosa in opening 62 until the fibrotic tissue response occurs, it may assist retainer 66 in long-term fixation of medical device 12 and may allow retainer 66 to be bioabsorbable. To assist release of the mucosa retained in openings 62 by the fibrotic tissue response-inducing material, known ablation techniques may be applied within lumen 63 to diminish the mucosa bulging in openings 32. Such ablation techniques are relatively non-harmful to the patient. Λn optional prying tool 65 may be used to pull wall 18 away from the mucosa in openings 62, such that the tissue releases from the openings. Alternatively, the retainer having a penetrating component could be an elongated member (not shown), such as a suture, that is passed by the physician through the mucosa extending into the lumen to capture the mucosa at openings 62. Alternatively, a plurality of retainers may be used, one for each of the openings. An alternative embodiment of a medical device 112 has a wall 118 that defines an outer surface 120 and an inner surface 119 (Figs. 4 and 5). Inner surface 119 may define a lumen (not shown). Wall 118 is configured to the size and shape of a hollow organ or cavity that is lined with the mucosa. Medical device 112 includes a fixation mechanism 160 that is adapted to fix wall 118 with the mucosal tissue lining the hollow organ or cavity. Fixation mechanism 160 may be adapted to be disabled from within the lumen defined by wall 118 in order to detach the medical device from the tissue.

Fixation mechanism 160 is in the form of one or more openings, such as through-openings 162 in wall 118, and at least one retainer that captures the mucosa extending through said opening into the lumen. In the illustrated embodiment fixation mechanism 160 includes at least two openings 162 that are closely spaced, thereby defining tissue apposition openings. The tissue apposition openings are separated by a spacer or bridge 64. As the mucosa passes through openings 162, the bulges of the mucosa tend to bridge spacer 64 and come together in apposition. Openings 162 are of a size to encourage the tissue, such as the mucosa, to pass through the openings upon insertion of the medical device 112 upon deployment of the device. A retainer 166 may be utilized to retain the mucosa captured in openings 162. The retainer, such as a clip, may be used to retain the sections of the mucosa within openings 162. Clip 166 may join the bulges of the mucosa in apposition. Clip 166 may have a pressure component by applying pressure to the sections of the mucosa within opening(s) 162. The engaging ends of clip 166 may also be configured with a penetrating component to penetrate the sections of the mucosa. Retainer 166 may also be in the form of techniques used to promote fusion of the sections of the mucosa in apposition, such as by abrading the tissue, utilizing a sclerosant agent, or the like. This assists in retaining the sections of the mucosa in openings 162.

Although two openings and one spacer are illustrated, the skilled artisan would recognize that a greater or lesser number of openings and spacers may be utilized. The layout of the openings may be arranged to accommodate the structure of the wall of the medical device. For example, if wall 118 included a spiral structural member, such as a wire mesh, the tissue apposition openings could be spirally formed, as illustrated in Fig. 4, between the wraps of the structural member. The clip can be made of a bioabsorbable material with the fusion of the sections of the mucosa in apposition used for long-term fixation once the clip resolves. To remove medical device 112, the retainer can be accessed and removed from within the lumen, such as endoscopically, and any fused mucosa removed, such as by ablation. Medical device 112 can then be moved within the organ or cavity or removed from the patient. Clip 166 may, alternatively, have a portion made of a fastener, such as Velcro®, and attach over the sections of the mucosa extending through openings 162 by attaching to surface 119 adjacent to the openings. Other variations will be apparent to the skilled artisan. In yet a further embodiment, a medical device 212 includes a wall 218 that is generally configured Io the size and shape of a hollow organ or cavity of the body. Medical device 212 includes a fixation mechanism 260 including an opening 262 defined between two moveable portions of wall 218. Opening 262 spans the length of wall 218 in the direction of the central axis of the generally tubular shape of the wall. Fixation mechanism 260 may further include a retainer 266 defined by opening 212. Retainer 266 has a pressure component, wherein opening 262 is capable of both receiving a section of the mucosa and putting sufficient pressure on the section of the mucosa to retain the mucosa in the opening. However, the pressure is not high enough to cause ischemia of the mucosa. Operation of medical device 212 can be described with respect to an esophageal stent for illustration purposes. Medical device 212 is selected to provide an interference fit with the esophagus. It may be delivered in the state illustrated in Fig. 7 using conventional techniques, such as an over tube. Once it is in the desired position, wall 218 is expanded such as by using a balloon or other tool, which may cause dilation of the esophagus. This causes wall 218 to assume the state illustrated in Fig. 6, thereby allowing the mucosa to bulge into opening 262. The wall is then allowed to relax to the state illustrated in Fig. 7 by releasing of the balloon or other tool. The mucosa will be retained in opening 262 with retainer 266.

In another embodiment illustrated in Figs. 8 and 9, a medical device 312 includes retainer 366 that is made up of the same pressure component of retainer 266 but further includes a penetrating component in the form of a series of needles or tines 367 that extend from one or both edges of the opening toward the opposite edge. A section of the mucosa is received in opening 362 by separating the moveable portions of wall 318, as illustrated by the arrows in Fig. 8. With the mucosa bulging into opening 362, the force is removed from wall 218 allowing it to return to the configuration shown in Fig. 9. The mucosa is retained by the needles of the retainer being moved together by the moveable portions of the wall as well as the force component previously described. In yet a further embodiment, a medical device 412 including a wall 418, which is configured to the size and shape of the hollow organ or cavity in which it is placed, has a fixation mechanism 460 (Fig. 10). Fixation mechanism 460 includes an opening 462 at an end of wall 418. With wall 418 forming an interference fit with the mucosa of the hollow organ or cavity, the mucosa will bulge over the end of wall 418 to provide retention. Fixation mechanism 460 may further include a retainer 466 having a series of needles or tines 467 that are arranged in order to engage the bulge of the mucosa when retainer 466 is moved axially into juxtaposition with wall 418. Retainer 466 could be initially moveably connected with wall 418 or could be a separate piece, as illustrated in Fig. 10. Also, another such retainer could be applied to an opposite end of wall 418.

Other embodiments will be apparent to the skilled artisan. For example, the wall defining the medical device may be made up of concentric cylinders that can be radially rotated with respect to each other. A fixation mechanism may be provided in the form of each of the cylinders defining an opening in its wall that can be moved into registry with the opening in the other cylinder by rotation of the cylinders to capture a bulge of the mucosa and apply pressure to the mucosa. A penetrating component can be applied to the retainer by the placement of needles or tines at the openings. The mucosa can be captured in the opening formed by rotating the cylinders in one radial direction to align the openings in the cylinders. The captured mucosa can be retained by rotation of the cylinders in the opposite radial direction to reduce the size of the opening, apply pressure to the mucosa and force the needles or tines toward each other. The rotation can be accomplished by a tool, such as a balloon, that is inserted in the device after placement to engage the innermost cylinder to rotate that cylinder. The tool is removed after the fixation mechanism is engaged.

It should be understood that retainers 60, 60', 160, 260, 360 and 460 may be made from a bioabsorbable material, a non-absorbable material, or a combination of both. Changes and modifications in the specifically described embodiments can be carried out without departing from the principles of the invention which is intended to be limited only by the scope of the appended claims, as interpreted according to the principles of patent law including the doctrine of equivalents.
