Abstract:
According to some embodiments, a method of accessing an intervertebral space of a patient's spine in a minimally invasive manner compromises creating a passage from a posterior end of a pedicle of a vertebral member using a probe, advancing the probe through the pedicle and to a main body portion of the vertebral member, advancing the probe through a superior endplate of the vertebral member and into the intervertebral space and enlarging the passage using at least one tap to create an enlarged passage from a posterior of the pedicle to the intervertebral space. In some embodiments, the enlarged passage traverses at least three cortical layers of the vertebral member.
Abstract:
An orthopedic implant includes a first member that defines a longitudinal axis, a first wall and a second wall. The first wall defines at least a portion of a chamber. The second wall defines a first graft containment cavity. The chamber is separate from the first graft containment cavity. A second member defines a first wall disposed for sealed engagement with the first wall of the first member. The first wall of the second member defines at least a portion of the chamber. The second member is configured for movement along the longitudinal axis relative to the first member. Methods of use are disclosed.
Abstract:
Embodiments of the invention include expandable medical implant systems and methods. The systems may include devices to reinforce a tube through which a fill material may be moved at least in part into expandable medical implants. In some embodiments, an implant replaces one or more of vertebral bodies, portions of vertebral bodies, discs, and portions of discs of the spine.
Abstract:
An implantable medical device for implantation in a mammal joint having at least two contacting surfaces is provided. The medical device comprises; an artificial contacting surface adapted to replace at least the surface of at least one of the mammal's joint contacting surfaces, wherein the artificial contacting surface is adapted to be lubricated, when implanted in said joint. Furthermore the medical device comprises at least one inlet adapted to receive a lubricating fluid from a reservoir, at least one channel at least partly integrated in the artificial contacting surface in connection with the at least one inlet for distributing the lubricating fluid to the surface of the artificial contacting surface. The medical device could be adapted to be operable by an operation device to receive the distributed lubricated fluid from a reservoir.
Abstract:
A lubrication device for lubricating a joint of a human or mammal patient, which is entirely implantable in a patient's body, comprises a reservoir for storing a lubricating flu- id and a fluid connection for introducing the lubricating fluid into the joint when the de- vice is implanted in the patient's body. Further, the fluid connection comprises a fluid connection device connecting the reservoir with the joint such that a lubricating fluid flow is established from the reservoir into the joint. The fluid connection comprises either an infusion needle adapted to be intermittently placed into the joint for injecting the lubricating fluid, or a tube adapted to be permanently placed into the joint for continuously injecting the lubricating fluid.
Abstract:
A medical device, system, and method for treating hip joint osteoarthritis by providing a hip joint surface is provided. The hip joint comprising an acetabulum, being a part of the pelvic bone, comprising an acetabulum surface, and a caput femur, being a part of the femoral bone, comprising a caput femur surface. The medical device comprises a first sealing member adapted to be placed in the hip joint for creating a hollow space together with; the acetabulum, or an artificial replacement therefor, and the caput femur, or an artificial replacement therefor. The first sealing member is further adapted to have a shape adapted to seal the hollow space for receiving, within the hollow space, a material for resurfacing at least one of the acetabulum surface and the caput femur surface.
Abstract:
Disclosed is a system for deploying an expandable medical implant comprising : an expandable medical implant (1) with a base (2) and an expandable end (3) and an enclosed volume between the base and the expandable end; and an elongated member (101) with a distal end (103) and a proximal end (102) wherein the distal end is coupled to the expandable end of the expandable medical implant, and the elongated member is in contact with the base of the expandable medical implant to provide a connection between the expandable end and the base; wherein the proximal end extends from the expandable implant and the proximal end is configured to receive a force applied along its length.
Abstract:
An artificial joint associated with an implant having a pair of three dimensional and structurally extending bones, each defining a contoured and opposing end face, which collectively defines a joint location. At least one plasticized and three dimensional shaped disk, such as a hardened and sanitary plastic material, is seated within a selected end cavity associated with a first of the bones. The disk exhibits an exterior surface configuration mating with an opposing end face of the other bone and which is biased, such as by a pressurized and fluid-filled bladder seated against an underside of the disc, in a contacting fashion against the other bone to establish a continuous wear surface.
Abstract:
Vertebral body replacement apparatuses, systems, and methods are provided. In various examples, an implantable device is configured to be inserted between a first vertebral body and a second vertebral body. The implantable device includes a first endplate configured to contact the first vertebral body. A second endplate is configured to contact the second vertebral body. An expansion bladder is disposed between and coupled to the first endplate and the second endplate. The expansion bladder includes a first chamber and a second chamber. The first chamber and the second chamber are sealed from fluid communication with one another. An injection port is disposed through one of the first endplate or second endplate. The injection port includes a first channel in fluid communication with the first chamber and a second channel in fluid communication with the second chamber.
