Implantable prosthesis
InactiveUS6610006B1Reduce the possibilityReduce postoperative painDiagnosticsLigamentsRepair siteIntraabdominal pressure
An implantable prosthesis for repairing an anatomical defect, such as a soft tissue and muscle wall defect. The prosthesis is configured to reduce the likelihood that an applied force at the repair site, such as due to intraabdominal pressure or tissue shrinkage, can lead to detrimental effects associated with tension at the anchoring locations between the prosthesis and host tissue and / or contraction of the prosthesis. In this regard, the prosthesis may be configured to limit the amount of tension at the anchoring locations caused by the application of a force or pressure to the prosthesis and / or contraction of the prosthesis. Alternatively, the prosthesis may be configured to compensate for contraction of the prosthesis due to tissue shrinkage at the repair site. The prosthesis may be configured to both limit tension at the anchoring locations and compensate for tissue shrinkage. The prosthesis may facilitate a reduction in postoperative discomfort, a recurrence of the defect, or the creation of a new defect associated with tension and / or prosthetic contraction.

Implantable prosthesis
An implantable prosthesis for an anatomical defect, such as a tissue or muscle defect, that promotes tissue or muscle growth into the prosthesis and subsequently strengthens the area of the defect. At least one pocket and preferably two concentric pockets may be provided to aid with manipulating the prosthesis. Where two pockets are used, a barrier or partition exists between the pockets and the outer pocket allows manipulation of the outer periphery. The incidence of postoperative adhesions between a portion of the prosthesis and tissue, muscle or organs may be minimized with the use of a barrier layer. Reinforcing members may be attached to portions of the prosthesis to aid in positioning and deployment in the area of desired coverage without rendering the prosthesis unduly difficult to implant or uncomfortable for the patient. Typically, two concentric members are employed. Further, the prosthesis is constructed to allow it to be provisionally held in place at desired locations by openings in the pockets that allow access for a stapler or sewing device.

Bioresorbable hydrogel compositions for implantable prostheses
Crosslinked compositions formed from water-insoluble copolymers are disclosed. These compositions are copolymers having a bioresorbable region, a hydrophilic region and at least two cross-linkable functional groups per polymer chain. Crosslinking of these polymers can be effected in solution in organic solvents or in solvent-free systems. If crosslinking occurs in a humid environment, a hydrogel will form. If crosslinking occurs in a non-humid environment, a xerogel will form which will form a hydrogel when exposed to a humid environment and the resulting crosslinked materials form hydrogels when exposed to humid environments. These hydrogels are useful as components in medical devices such as implantable prostheses. In addition, such hydrogels are useful as delivery vehicles for therapeutic agents and as scaffolding for tissue engineering applications.

ActiveUS20050240259A1Limited extentLimit longitudinal movementStentsBlood vesselsThin layerSpot welding
Disclosed is an anchoring element for an implantable prosthesis that includes a barb, wherein the anchoring element, which includes a basal portion, comprises a thin layer of material, such as a cannula or sheet of metal, that extends or wraps at least partially around the strut of the prosthesis to which it is attached. The barb is configured to extend outward from the basal portion to penetrate adjacent tissue. The anchoring element is either permanently affixed to the strut, such as by laser or spot welding, crimping, or some other method of bonding, or allowed to slide longitudinally over the strut between two points or stops in order to relieve any excessive loads placed upon the barb that could cause fracture. The anchoring element and strut may be configured to limit axial rotation of the barb, while still allowing longitudinal movement. In another embodiment, the slidable anchoring element may be manipulated following initial deployment to reorient the barb toward the implantation site.

An implantable prosthesis for repairing an anatomical defect, such as a tissue or muscle wall hernia, including an umbilical hernia, and for preventing the occurrence of a hernia at a small opening or weakness in a tissue or muscle wall, such as at a puncture tract opening remaining after completion of a laparoscopic procedure. The prosthesis includes a patch and / or plug having a body portion that is larger than a portion of the opening or weakness so that placement of the body portion against the defect will cover or extend across that portion of the opening or weakness.

The tether may be configured to extend through the defect and outside a patient's body to allow a surgeon to position and / or manipulate the patch from a location outside the body. An indicator may be provided on the tether as an aid for a surgeon in determining when the patch or plug has been inserted a sufficient distance within the patient. A support member may be arranged in or on the patch or plug to help deploy the patch or plug at the surgical site and / or help inhibit collapse or buckling of the patch or plug. The patch or plug may be configured with a pocket or cavity to facilitate the deployment and / or positioning of the patch or plug over the opening or weakness.

Implantable prosthesis with displaceable skirt
An implantable prosthesis is provided having a radially-expandable tubular body and at least one skirt extending therefrom. The skirt terminates in a peripheral edge, wherein at least portions of the peripheral edge are free and displaceable to a greater diameter of the tubular body. Thus, with the implantable prosthesis being a stent-graft used to treat an aortic aneurysm (e.g., abdominal aortic aneurysm (“AAA”)), the skirt may be used to inhibit Type I endoleaks upon its selective displacement in response to irregular aortic shaping and / or aneurysm neck expansion. The skirt may actively inhibit Type I endoleaks by forming a physical barrier against flow between the tubular body and the aortic wall. In addition, the skirt may passively inhibit endoleak formation by sufficiently restricting blood flow to allow coagulation and clot formation, which would act as a barrier against endoleakage.

Osseo-integrated sub-periosteal implant
A sub-periosteally implantable prosthesis support structure for a fixed or detachable dental prosthesis includes a framework fitted to and generally conforming to the inner and outer contours of the bony ridge structures of a person. The framework is configured to provide a space extending generally normal to the bony ridge structure to an apex to provide space for subsequent bone growth. A plurality of denture support posts are distributed about the framework and depend outwardly from the apex in substantial alignment with the bony ridge structure. During the fabrication of the prosthesis support structure, a bio-compatible fine mesh screen is fixed to and spans, tent-like, the framework to substantially overlay the bone structure and the space provided for subsequent bone growth. After the support structure has been implanted, the growth of bone into the space and around the support structure is promoted to osseo-integrate the support structure with the person's bony ridge, thus providing a secure foundation for a denture or fixed dental prosthesis configured for detachable or fixed coupling with the denture support posts. The support structure may be made, partly or wholly, from either non-resorbable material, such as titanium stock and mesh, or from a resorbable material such as Vicryl TM .

Implantable drug delivery prosthesis
An apparatus and associated method for delivering a therapeutic substance to a vascular lumen, using an implantable prosthesis, such as a stent, which has grooves or trenches formed thereon. The grooves are formed on specific regions of the stent struts to increase the flexibility of the stent. The grooves also provide a therapeutic material carrying capability for treating intravascular ailments, such as instent restenosis and thrombosis. The therapeutic material loading of the grooves can be accomplished in several ways. For example, a pure therapeutic material or a pre-mixed material with a polymer solution, which enhances the adhesion properties of the material, may be deposited directly in to the grooves using conventional spray or modified dip techniques. In another example, a microextruded monofilament therapeutic material can be wound about the stent, such that the monofilament becomes embedded in the grooves.
