An intervertebral implant is provided for insertion between a first vertebral body and a second vertebral body defining an intervertebral space. The implant includes a first anchoring part for anchoring at the first vertebral body, a second anchoring part for anchoring at the second vertebral body, and a joint configured to connect the first and second anchoring parts together. The joint includes a first joint part carried by the first anchoring part, and a second joint part carried by the second anchoring part. The implant further includes at least one restoring device adapted to exert a restoring force on the first or second joint part. The restoring force of the at least one restoring device transfers the first or second joint part from a deflected position back to a normal position and/or limits movement of the first or second joint part away from the normal position.

A patellar trial and drill guide for use during knee replacement surgery comprising an articular surface member and a fixation peg drill guide. The articular surface member is the exact geometry as the artificial patellar implant, and the drill guide aligns the holes for the fixation pegs of the artificial patellar implant. The patellar trial is placed on the resected patella in the desired position, a patellar clamp is used to temporary fix the patellar trial to the patella. The patella is then returned to its normal position and a trial reduction of the total knee replacement is completed. If the placement and/or size of the patellar trial is unacceptable, the patella is inverted, the patellar trial removed, and a different sized trial or new location is determined. The new patellar trial is secured to the resected patella, and another trial reduction of the total knee replacement is completed. This procedure can be repeated until the patellar trial is the correct size and in the proper location. If the placement of the patella is acceptable, the patella is inverted, the articular surface member removed, fixation peg holes are drilled using the fixation peg holes of the drill guide, and an artificial patellar implant is implanted on the patient's remaining patella.

The present invention relates to limited incision total joint replacement methods for performing surgery on a joint in a patient's body, such as a knee. In one embodiment, an incision is made in a knee portion of one leg while a lower portion of the one leg is extending downward from an upper portion of the one leg and while a foot connected with the lower portion of the one leg is below a support surface on which the patient is disposed. The incision is relatively short, for example, between seven and thirteen centimeters. A patella may be offset from its normal position with an inner side of the patella facing inward during cutting of a bone with a cutting tool. During cutting of the bone, one or more guide members having opposite ends which are spaced apart by a distance less than the width of an implant may be utilized to guide movement of a cutting tool.

An arterial needle removes blood from the access to an extracorporeal circuit comprising a dialyzer and a venous needle returns the blood to the access site. Blood passes along one side of the membrane of the dialyzer and dialysis fluid along the other side. The concentration (Cd norm and Cd rev) of urea in the dialysate emitted from the dialyzer is measured with the needles in the normal position and in a reversed position. The access flow rate before the arterial needle is calculated according to the formula:in which Keff is the effective clearance of the dialyzer and Qa is the access flow rate.

The rated system pressure in a pressure control system is adjusted through a pressure relief valve (2). In addition to the pressure relief valve (2), the system includes a check valve (4), a pressure sensor (3), a position switch (10), a first pressure adjustment member (13) for the relief valve, a second pressure adjustment member (12) for the check valve (4), an actuator (16), and a microcontroller (15) with a memory (6) and a display (7). Faults caused by pressure adjustment interactions are prevented by permitting an adjustment of the pressure relief valve only if the check valve is fully open and a pump provides pressure. For this purpose the actuator (16) of the check valve in its normal position prevents an adjustment of the pressure relief valve. Opening the check valve by the actuator permits adjusting the pressure relief valve (2) and the switch (10) operated through the actuator sends a signal to the microcontroller to drive the pump. When the check valve is opened, the pressure is equalized throughout the system, so that adjusting the response pressure of the pressure relief valve automatically adjusts the system pressure to a desired rated pressure.

The wire of the wire reel may be wound as the electronic device is moved from the withdrawn position to the normal position.

An implement for manipulating and cutting a knotted suture includes a body member having a handle at one end, and a knot-engageable section at the opposite end for engaging the knotted suture to be cut; and a cutting member carried by the body member and having an end portion formed with a cutting edge for cutting the knotted suture at a predetermined distance from the knot. The cutting member is movable along its longitudinal axis from a normal position to an actuated position for cutting the knotted suture. The knot-engageable section of the body member is formed with an axial bore for receiving the end portion of the cutting member when the cutting member is moved to its actuated position, and with an angled bore intersecting the axial bore at an angle to the longitudinal axis for receiving the knotted suture. The knot is located at one side of the angled bore and the suture to be cut extends through the angled bore to the opposite side, such as to permit hand-tensioning the knot and then cutting the suture by moving the cutting member to its actuated position.

A connecting device for a weapon accessory has a seat having a sliding rack that removably connects the longitudinal groove of a weapon, and one or more gripping blocks disposed adjacent corresponding side walls of the seat.
