A device for performing a surgical procedure on a knee comprises a femoral assembly comprising a stationary femoral member attachable to the distal femur, an adjustable femoral member movably coupled with the stationary member to adjust tension in at least one ligament of or adjacent the knee and an adjustment mechanism coupled to the assembly. The adjustable member includes at least one positioning feature that moves relative to the distal femur as the adjustable member is adjusted and identifies at least one position on the distal femur. The adjustable member is movably couplable with a tibial member engaged with a proximal tibia to allow the knee to be moved through a range of motion without removing the femoral and tibial members. The mechanism includes an actuator positioned proximate a medial or lateral portion of the adjustable member. The actuator is configured to adjust an opposite portion of the adjustable member.

An implant insertion apparatus for guiding surgical instrumentation and facilitating insertion of surgical implants into an intervertebral space includes an adjustable element defining a longitudinal passageway dimensioned to guide the surgical instrumentation inserted through the longitudinal passageway. The adjustable element has an elongate body and an extended body that are movable relative to one another for varying the length of the adjustable element. The apparatus also includes an engaging element insertable into the intervertebral space between adjacent vertebrae. The engaging element is releasably secured to a distal end of the elongate body.

Systems, apparatus, and methods are provided for promoting blood flow to a target tissue. In one aspect, the invention involves canalizing or boring channels, divots, trenches or holes through an avascular connective tissue, or through a tissue having sparse vascularity, such as a tendon or a meniscus, in order to increase blood flow within the tissue. In one method, an active electrode is positioned in close proximity to a target site on a tendon, and a high frequency voltage difference is applied between the active electrode and a return electrode to selectively ablate tendon tissue at the target site, thereby forming a channel or void in the tendon. The active electrode(s) may be moved relative to the tendon during, or after, the application of electrical energy to damage or sculpt a void within the tendon, such as a hole, channel, crater, or the like. In another aspect of the invention, an electrosurgical probe is used to elicit a wound healing response in a target tissue, such as an injured tendon, in order to stimulate vascularization of the target tissue. The present invention may also be used for vascularization of a torn or damaged tissue in conjunction with a surgical repair procedure.

The present invention provides an electrophoretic system, apparatus, and method of use thereof for the preparation of a tissue-derived bioprosthesis.

Catheter systems include direction-sensitive, multi-polar tip electrode assemblies for electroporation-mediated therapy, electroporation-induced primary necrosis therapy and electric field-induced apoptosis therapy, including configurations for producing narrow, linear lesions as well as distributed, wide area lesions. A monitoring system for electroporation therapy includes a mechanism for delivering electrochromic dyes to a tissue site as well as a fiber optic arrangement to optically monitor the progress of the therapy as well as to confirm success post-therapy. A fiber optic temperature sensing electrode catheter includes a tip electrode having a cavity whose inner surface is impregnated or coated with thermochromic / thermotropic material that changes color with changes in temperature. An optic fiber / detector arrangement monitors the thermochromic or thermotropic materials, acquiring a light signal and generating an output signal indicative of the spectrum of the light signal. An analyzer determines an electrode temperature based on the detector output and predetermined spectrum versus temperature calibration data.

Surgical eversion apparatus for preparing a conduit for anastomosis in a human patient comprises an everting member having a loop shaped portion adapted to be inserted into an end portion of a conduit harvested from a human patient and configured to fold a portion of the conduit end portion over itself when moved proximally away from the end of the conduit and along the conduit while a portion of the conduit is held fixed relative thereto. A method of everting a graft comprises positioning a graft in a support device such that an end portion of the graft extends therefrom; introducing a generally looped shaped member into the end portion of the graft extending from said support device; and moving the looped shaped member over the support device to fold at least a portion of the end portion of the graft over the support device.

In a method of high spatial resolution imaging or modifying a structure, the structure is marked with a substance which is selected from the group of substances which can be transferred from a first state having first optical properties to a second state having second optical properties by means of an optical switch over signal. Then, the second state of the substance is adjusted with the switch over signal except for a spatially limited area. If the substance and the switch over signal are adapted to each other in such a way, that everywhere where the switch over signal exceeds a threshold value essentially the second state of the substance is adjusted, and if the spatial area purposefully omitted by the switch over signal is an intensity minimum of an interference pattern, the spatial area of the structure in which the substance is within the first state becomes smaller than the diffraction limit for the switch over signal.

External or internal monitoring equipment is used to automatically determine optimal programming parameters for a CRT based on externally or internally derived measurements of cardiac performance, anisotropic myocardial deformation (AMD) or both. The ideal programming parameter, operational parameter, represents optimal interval timing between multiple electrodes within the CRT, and is generated by such a closed loop control system. The closed loop system may be semi-automatic and implement connectivity to external ultrasound equipment or externally derived measurements of transthoracic impedance. Preferably, the operational parameter is determined by a closed loop system using internally derived intracardiac and intrathoracic electrograms and impedance measurements that describe cardiac performance and electromechanical dysynchrony in real time. Such a CRT has a control system that automatically optimizes performance by a system of checks and balance.

Body tissue ablation is carried out by inserting a probe into a body of a living subject, urging the probe into contact with a tissue in the body, generating energy at a power output level, and transmitting the generated energy into the tissue via the probe. While transmitting the generated energy the ablation is further carried out by determining a measured temperature of the tissue and a measured power level of the transmitted energy, and controlling the power output level responsively to a function of the measured temperature and the measured power level. Related apparatus for carrying out the ablation is also described.

Active matrix light emitting device display and its driving technique is provided. The pixel includes a light emitting device and a plurality of transistors. A capacitor may be used to store a voltage applied to a driving transistor so that a current through the light emitting device is independent of any shifts of the transistor and light emitting device characteristics. A bias data and a programming data are provided to the pixel circuit in accordance with a driving scheme.
