Intravascular devices (e.g., stents, stent grafts, covered stents, aneurysm coils, embolic agents and drug delivery catheters and balloons) are used in combination with fibrosing agents in order to induce fibrosis that may otherwise not occur when the implant is placed within an animal or to promote fibrosis betweent the devices and the host tissues. Compositions and methods are described for use in the treatment of aneurysms and unstable arterial (vulnerable) plaque.

An anchor and procedure for placing a medical implant, such as for monitoring physiological parameters. The anchor includes a central body in which a medical implant can be received. arms and members extend radially from first and second ends, respectively, of the central body. Each member defines a leg extending toward distal portions of the arms to provide a clamping action. The anchor and its implant are placed by coupling first and second guidewires to first and second portions of the anchor, placing an end of a delivery catheter in a wall where implantation is desired, inserting the anchor in the catheter with the guidewires to locate the anchor within the wall, deploying the arms of the anchor at one side of the wall followed by deployment of the members at the opposite side of the wall, and thereafter decoupling the guidewires from the anchor.

A system and method for inserting an implant into a cavity is disclosed, which may include advancing an implant insertion instrument toward a pair of adjacent bodies, the implant insertion instrument having two opposed ramps, wherein each ramp has a distal tip and wherein the longitudinal axes of the opposed ramps are separated by an initial angle; inserting the distal tips of the opposed ramps between the adjacent bodies, thereby creating an initial interbody cavity between the adjacent bodies; expanding the interbody cavity while maintaining the initial angle between the longitudinal axes of the opposed ramps; placing the implant in a final location between the adjacent bodies; transferring a compressive force urging the adjacent bodies together from the opposed ramps to the implant; and extracting the implant insertion instrument from the interbody cavity.

Soft tissue implants (e.g., breast, pectoral, chin, facial, lip, and nasal implants) are used in combination with an anti-scarring agent in order to inhibit scarring that may otherwise occur when the implant is placed within an animal.

An implant is placed within Schlemm's canal of the eye and provides tension to the trabecular meshwork. The tension is continuous and increases the aqueous outflow without the necessity of administering cholinergic drugs to treat glaucoma.

The present invention provides a device and method for facilitating the placement of dental implants by use of an implant placement locator and a sequentially sized drill orientation tube series. The implant placement locator disclosed herein comprises a visible radiolucent moldable grid, a set of radiopaque markers located at known intervals within the moldable grid, and a plastic sheeting encasing the visible radiolucent moldable grid and the radiopaque markers. The method of the present invention comprises obtaining a radiograph of a patient's mouth with the implant placement locator overlaying the patient's dental ridge and then transferring reference points as indicated by the location of the radiopaque markers relative to existing teeth and other oral structures to a dental stone model. In a preferred embodiment, drill bits are directed in the desired trajectory into the patient's available lower or upper jaw bone by use of drill orientation tubes in combination with the implant placement locator. A sequentially sized set of spacers is provided having sequentially sized inside diameters to direct varying diameter drills. Drill guide parallelism is thus provided by the invention.

An anchor for a medical implant, a method of manufacturing an anchor, and a delivery system and method for delivering a medical implant, such as for monitoring physiological parameters, for example, for diagnosing and/or monitoring and/or treating cardiovascular diseases, such as CHF and CHD. The anchor includes a base member, arms, legs, features for securing the medical implant to the base member, and features for connecting the anchor to a connector. The anchor has a deployed configuration in which the arms radially project from a first end of the base member and the legs radially project from an opposite end of the base member. When deployed, the arms and legs terminate at extremities that are opposing but not aligned with each other.

A spinal vertebral implant includes a substantially rectangular shaped base section made from a solid piece of bone. A nose section extends integrally from the substantially rectangularly shaped base section and preferably has a generally tapering shape to foster entry between adjacent vertebrae. The nose section tapers distally and inwardly from the base section to form a generally pointed or rounded distal tip portion and comprises a solid piece of bone. Serrated sides assist the implant in gripping adjacent upper and lower vertebrae and in being maintained therebetween. The serrated sides are angled in a manner that encourages the implant to be placed between the vertebrae and locked therebetween upon such placement. First and second implants may be placed into respective left and right sides of an intervertebral space. A method for placing one or more implants between the adjacent vertebrae comprises forming a slot configured to receive an implant and inserting the implant into the slot. Each slot is preferably formed from an upper slot portion and a lower slot portion in the posterior portion of adjacent upper and lower vertebrae, respectively. Instruments for performing the method include osteotomes, impactors, and spacers.

Implants are used in combination with a fibrosis-inducing agent in order to induce fibrosis that may otherwise not occur when the implant is placed within an animal or increase fibrosis between the implant and the host tissue.

Surgical instrumentation for use in placing an implant into a disc space between a pair of spinal vertebrae may include: (a) a distractor having a distal end that may be placed into the disc space between the pair of spinal vertebrae; (b) an inserter for use in moving the implant toward the disc space between the pair of spinal vertebrae; and, (c) a distractor/inserter rail/groove interconnection that interconnects the distractor and the inserter for relative movement thereby.
