The present invention provides a system for implementing surgical procedures which includes an ultrasonic surgical hand piece having an end-effector, a console having a digital signal processor (DSP) for controlling the hand piece, an electrical connection connecting the hand piece and the console, and a memory, such as an EEPROM (Electrically Erasable Programmable Read Only Memory), disposed in the electrical connection. The console sends a drive current to drive the hand piece which imparts ultrasonic longitudinal movement to the blade. The console reads the memory and authenticates the hand piece for use with the console if particular or proprietary data are present in the memory. Moreover, to prevent errors in operating the hand piece, the memory can store certain diagnostic information which the console can utilize in determining whether the operation of the hand piece should be handicapped or disabled. Furthermore, the memory can be used to reprogram the console, if needed.

A system and method for the temporary closure of a wound, especially an abdominal wound, to facilitate re-entry, final closure, and long term healing of the wound. An abdominal wound dressing and methods of use are described that enable the application of negative pressure to the wound site in a site healing promoting manner while also limiting the formation of adhesions that would prevent the removal of the dressing.

Apparatus and methods are provided for thermally and / or mechanically treating tissue, such as valvular structures, to reconfigure or shrink the tissue in a controlled manner. Mechanical clips are implanted over the leaflets of a valve, e.g., in the heart, either alone or after thermal treatment to cause the valve to close more tightly. The clips are delivered by a catheter and may be configured to traverse directly over the valve itself or to lie partially over the periphery of the valve to prevent obstruction of the valve channel. The clips can be coated with drugs or a radiopaque coating. Alternatively, individual anchors with a tensioning element, like a suture, may be used to approximate the valves towards each other. The catheter can also incorporate sensors or energy delivery devices, e.g., transducers, on its distal end.

Aspects of the present disclosure are presented for a surgical instrument having one or more sensors at or a near an end effector and configured to aide in the detection of tissues and other materials and structures at a surgical site.

Examples of sensors include laser sensors used to employ Doppler shift principles to detect movement of objects at the surgical site, such as blood cells; resistance sensors to detect the presence of metal; monochromatic light sources that allow for different levels of absorption from different types of substances present at the surgical site, and near infrared spectrometers with small form factors.

The subject invention pertains to a method and apparatus for placing a minimally-invasive access with respect to a patient's bone or other non-soft tissue. The subject invention can use a drilling machine incorporating an ultrasound motor. The subject drilling machine can be applied to sample, for example, bone biopsies under MRI control.

Filtering of optical fibers and other related devices. High-energy methods for depositing thin films directly onto the ends of optical fibers can be used to produce high-quality, high-performance filters in quantity at a reasonable cost. These high-quality filters provide the high performance needed for many demanding applications and often eliminate the need for filters applied to wafers or expanded-beam filtering techniques. Having high-quality filters applied directly to optical fiber and faces permits production of high-performance, micro-sized devices that incorporate optical filters. Devices in which these filters may be used include spectroscopic applications including those using fiber optic probes, wavelength division multiplexing, telecommunications, general fiber optic sensor usage, photonic computing, photonic amplifiers, pump blocking and a variety of laser devices.

Systems and methods of this invention display data using pixels with information indicated by color and intensity changes, particularly used for monitoring of physiological variables in real time. For certain methods, physiological data can be acquired by sensors, acquired data can be stored in data frames, data frames can be processed using computer-implemented methods, and processed data frames can be scaled to a display frame for display on a display device. Using such methods, a spot made up of a group of pixels can be updated during a time frame, or cycle using a computer-implemented method, such as addition, subtraction, multiplication, division or a time dependent function. Newly received data can be combined with prior received data to indicate time-dependent changes. In this way, each spot contains a cumulative history of data starting at some initial time. In other embodiments, visual contrast can be enhanced between desired data and other data. In further embodiments, two or more different types of data can be plotted together to indicate relationships between variables. Real time monitoring of signals during therapeutic treatment using light, electricity or other nerve or muscle stimuli can allow a user to monitor physiological responses during stimulation and to make rapid decisions about medical treatment.

A biodegradable vehicle and filler (referred to in this invention as biodegradable vehicle), which can be mixed with one or more biologically active substances (BAS), or can be used as a biodegradable filler to fill in cavities or body tissues in animals, birds and humans. The consistency and rheology, hydrophilicity and hydrophobicity, and in vivo degradation rates of the biodegradable vehicle is controlled by modulating the molecular weight of polymers and copolymers, concentration of plasticizers, ratios of two or more plasticizer in the blends, types of polymers and copolymers, copolymer ratios, and ratios of blends of polymers with different molecular weights or different copolymers. The biodegradable vehicle is mixed with one or more BAS (which is separately stored away from the biodegradable vehicle in an appropriate container) just prior to use. Mixing of the BAS with the biodegradable vehicle can be accomplished by simply stirring the mixture with a stirring device, or by triturating the mixture or employing an ointment mill or a suitable device or apparatus or equipment that can be used for blending / mixing. Alternatively, a device, which resembles two syringes, attached together with a removable partition or a valve assembly can also be used to uniformly mix the BAS with the biodegradable vehicle. The mixing is performed in order to dissolve or uniformly suspend the BAS particles in the biodegradable vehicle. Modulating the polymer to plasticizer ratio, polymer molecular weight, copolymer ratio, and hydrophobicity and hydrophilicity of the plasticizer controls the release of the BAS from the biodegradable vehicle.
