摘要:
Apparatus and methods for assessing tissue characteristics such as the dimensions and volume of an osteolytic lesion are disclosed. The apparatus may utilize ultrasound to provide visual and volumetric feedback related to a lesion or other tissue. Further the apparatus may be utilized to determine whether the lesion has been completely removed and filled with the appropriate amount of graft material.
摘要:
A chisel system for harvesting an implantable graft from an area of a human having a cartilage overlying a condyle, according to which a module is provided that has one end connected to a handle. A cutting surface is formed at the other end of the module that cuts through the cartilage and condyle.
摘要:
A surgical procedure for preparing a damaged area of a human knee to receive at least one graft, according to which a moldable material is positioned over the damaged area and removed after it hardens. The mold is used as a template to determine the number and/or a dimension of the openings to be formed in the damaged area for receiving corresponding grafts.
摘要:
A surgical procedure for implanting a graft according to which a dilator is inserted in a recipient opening and the graft is inserted in the dilator to cause outward expansion of the dilator into engagement with the portion of a bone surrounding the opening. After the dilator is removed from the opening, the bone surrounding the opening collapses around the graft to secure the graft in the opening.
摘要:
Each of an osteochondral plug graft and a kit comprises a trapezoid shaped construct configured for osteochondral implanting. An osteochondral regeneration method comprises forming a recipient socket in a chondral area of an articular joint in need of repair; harvesting a trapezoid shaped graft from another chondral area; and implanting the trapezoid shaped graft into the recipient socket.
摘要:
An implantable sensor for detecting changes in tissue density is disclosed. The implantable sensor includes a transducer adapted for detecting indicators of tissue density. The implantable sensor includes memory for storing data corresponding to the tissue density indicators detected by the sensor. A telemetry circuit is configured for transmitting the tissue density data outside of the body.
摘要:
A surgical instrument for assessing tissue characteristics such as tissue density and volume is disclosed. The surgical instrument is hand-held and includes transducers adapted for emitting and/or receiving acoustic signals. The surgical instrument utilizes pulse-echo to determine tissue characteristics. The surgical instrument may be utilized to determine such things as the size of a lesion and whether the lesion has been completely removed or filled with graft material.
摘要:
An implantable pedometer for measuring the amount of joint use is disclosed. The implantable pedometer includes a sensor adapted for detecting indicators of joint usage. A counter is configured for storing count data corresponding to the number of indicators detected by the sensor and a telemetry circuit is configured for transmitting the count data outside of the body.
摘要:
A sensor for detecting changes in spinal tissue is disclosed. The implantable sensor or surgical instrument includes a sensing element adapted for detecting indicators of tissue health. The sensor is configured for transmitting the tissue data outside of the body. Further a system and method are provided to utilize the sensed tissue properties to treat the patient's condition.
摘要:
A system and method are provided for monitoring the condition of the skeletal system and adjusting a treatment device to provide appropriate treatment in response to the sensed signal. More particularly, in one aspect the present invention is directed to a sensor for detecting changes at a spinal level and a dynamic treatment system adjustable in response to the detected changes.
