Implantable devices for musculoskeletal repair and regeneration
This application describes an implantable device for tissue repair comprising at least two fabrics with interconnecting spacer elements transversing, connecting, and separating the fabrics, forming the device. Some embodiments have fixation points which can be an extension of at least one of the fabrics. The implantable device allows modification of the two fabrics having varying constructions, chemistries, and physical properties. The spacer elements create a space between the two fabrics, which can be used for the loading of biological materials (peptides, proteins, cells, tissues), offer compression resistance (i.e. stiffness), and compression recovery (i.e., return to original dimensions) following deformation and removal of deforming load. The inclusive fixation points of the fabrics are designed to allow for fine adjustment of the sizing and tension of the device to promote integration with the surrounding tissues as well as maximize the compressive resistance. The fixation points can include either the first fabric, the second fabric, or the combination of both fabrics. This device is suitable for soft and hard tissue regeneration or replacement with a preference for musculoskeletal tissues including but not limited to cartilage (including hyaline (referred to as articular; e.g. cartilage on the ends of long bones), fibrous (e.g. meniscus or intervertebral discs), elastic (e.g. ear, epiglottis)), bone, muscle, tendon, ligament, and fat.
MENISCUS TEAR REPAIR SLING DEVICE
A meniscus tear repair sling device has a collagen membrane having a first end portion and a second end portion. The first end portion is configured to pass under a tear in a meniscus and wrap over and above the tear and extend past the meniscus and overlay the second end portion thereby enveloping a portion of the meniscus with a tear and forming the sling device. The first end portion and the second end portion form exposed overlying tails extending external of a knee joint. The tails are configured to be affixed to a portion of a tibia. The tails when tensioned close the tear by providing a lateral strain on the torn meniscus when the tails are affixed to a tibia adjacent the knee joint.
HIP JOINT INSTRUMENT AND METHOD
A surgical instrument for operating hip joint osteoarthritis in a human patient is provided. The hip joint comprises an acetabulum, being a part of the pelvic bone, and a caput femur, being the proximal part of the femoral bone. The surgical instrument is adapted to assist in the operating of the hip joint osteoarthritis from the abdominal side of the pelvic bone of said human patient.
Medical device and method for treatment of hip joint
A medical device for delivering an action to an area of a hip joint or its surroundings, inside a human body, is provided. The hip joint of a patient comprises a collum femur and a ball shaped caput femur, being the proximal parts of the femoral bone, and an acetabulum, being a bowl shaped part of the pelvic bone. The medical device comprising; an elongated member, having a length axis along its elongated distribution, comprising a first portion, adapted to enter the body of the patient, and a mechanical element, adapted to be used during an operation in the hip joint or its surroundings, inside the body. The first portion of the elongated member comprises a holding member adapted to hold the mechanical element inside the body of the patient, wherein the first portion of the elongated member have a first portion cross-section area substantially perpendicular to the length axis of the elongated member. The first portion is adapted to pass through a hole, in a bone of the patient, the hole having a hole cross-section area. The first portion cross-section area, is adapted to be smaller than said hole cross-section area. The mechanical element have a functional status, ready to deliver said action inside said body, when held by the holding member inside the body of the patient. The mechanical element is adapted to have a mechanical element cross-sectional area substantially perpendicular to the length axis of the elongated member, substantially larger than the first portion cross-sectional area and adapted to be unable to pass through the hole, when the mechanical element is in the functional status.
HIP JOINT DEVICE AND METHOD
A method for fixating an artificial convex caput femur surface to the pelvic bone of a patient, the method comprising the steps of: exposing the acetabulum surface, creating a hole or recess in the pelvic bone from the acetabulum side of the pelvic bone, providing the artificial convex caput femur, comprising an elongated member to the hip joint, inserting said elongated member in said hole, and performing an action on the acetabulum side of the pelvic bone such that the elongated member is structurally changed on the abdominal side of the pelvic bone or inside the pelvic bone.
Joint spacer
A joint spacer, in particular a knee spacer and a hip spacer is provided which is long-lasting and is sufficiently cushioned and abrasion-resistant and which can also support locally very high loads. A method for treating osteoarthritis by inserting a disk-shaped member into a joint of a patient is also disclosed.
Hip joint instrument and method
A method of treating a hip joint of a human patient using a pelvic drill comprising a driving member, a bone contacting and an operating device for operating said driving member. The method comprise the steps of cutting the skin of the human patient, dissecting an area of the pelvic bone on the opposite side from the acetabulum, creating a hole in said dissected area using said pelvic drill, said hole passing through the pelvic bone and into the hip joint of the human patient, and providing at least one hip joint surface to the hip joint, through said hole in the pelvic bone of the human patient. In one embodiment the method includes inserting a needle or tube like instrument into the patient's body for filling a part of the patient's body with gas and thereby expanding a cavity within the body.
Hip joint device, system and method
An implantable medical device for implantation in a hip joint is provided. The medical device comprises: at least one artificial hip joint surface adapted to replace at least the surface of at least one of the caput femur and acetabulum. At least one artificial hip joint surface comprises: a positioning hole with at least one opening in said at least one artificial hip joint surface. The hole is adapted to be placed and dimensioned such that the medical device is adapted to be fitted using a positioning shaft and at least partly surround the shaft, for positioning the at least one artificial hip joint surface in a desired position in the hip joint. The hole is adapted to be fitted using the positioning shaft, when the shaft is stabilized and placed in at least one of the femoral bone and the pelvic bone for positioning said medical device inside the hip joint.
Hip Joint Method
A method for implanting a medical device for lubricating a joint in a human body, said method comprising the steps of creating an opening reaching from outside of the human body into the joint, providing an artificial contacting surface to said joint, fixating the artificial contacting surface to the joint, implanting a reservoir in the human body, and lubricating said artificial contacting surface by pressurizing a lubricating fluid contained in said reservoir.
MICROCHANNELS IN SUBCHONDRAL BONE AND MEMBRANES COMPRISING SAME FOR THE TREATMENT OF OSTEOARTHRITIS
The present invention relates to the diagnosis and treatment of joint-related diseases, in particular osteoarthritis. Based on the analysis of the microarchitecture, such as microchannels, of the subchondral bone, the present invention provides methods for evaluating the health state of a joint as well as determining whether a joint is prone to develop or has already developed a disease correlated to joint and cartilage destruction. The invention further provides for membranes and other implants mimicking healthy subchondral bone structure suitable for promoting regeneration of joint structure and function.
