| 20110020779 | SKILL EVALUATION USING SPHERICAL MOTION MECHANISM - Software tools, methods and apparatus for objectively assessing surgical and medical procedural skills are described. Data corresponding to performance of a manipulative task by a subject is modeled using Markov modeling techniques and compared with stored models corresponding to each of a plurality of proficiency levels. A particular proficiency level is selected based on proximity of the subject data relative to each of the stored models. | 01-27-2011 |
| 20110196815 | METHODS FOR MANUFACTURING, INVENTORYING, AND SUPPLYING MEDICAL COMPONENTS - The present invention relates to methods for the manufacturing, inventorying, and supplying of medical components. In one exemplary embodiment, the method includes fabricating individual subcomponents of a modular medical device system as finished goods. The finished subcomponents may then be sterilized, stocked, and inventoried and, upon request from a consumer, the individual subcomponents may be supplied to the consumer. For example, the consumer may be a hospital, a surgeon, or a sales representative. Once the individual subcomponents are received by the consumer, the individual subcomponents may then be assembled by the consumer to form a final, implantable medical device. | 08-11-2011 |
| 20110277776 | SURGICAL SYSTEM STERILE DRAPE - A sterile drape, a surgical system with the drape, and a draping method are provided. In one embodiment, a sterile drape includes a plurality of drape pockets, each of the drape pockets including an exterior surface to be adjacent a sterile field for performing a surgical procedure and an interior surface to be adjacent a non-sterile instrument manipulator coupled to a manipulator arm of a robotic surgical system. The drape further includes a plurality of flexible membranes at a distal face of each of the drape pockets for interfacing between outputs of an instrument manipulator and inputs of a respective surgical instrument, and a rotatable seal adapted to couple a proximal opening of each of the drape pockets to a rotatable element at a distal end of the manipulator arm. | 11-17-2011 |
| 20110282351 | SURGICAL SYSTEM ENTRY GUIDE - An entry guide tube and cannula assembly, a surgical system including the assembly, and a method of surgical instrument insertion are provided. In one embodiment, the assembly includes a cannula having a proximal portion that operably couples to an accessory clamp of a manipulator arm, and a distal tubular member coupled to the proximal portion, the tubular member having an opening for passage of at least one instrument shaft. The assembly also includes an entry guide tube rotatably coupled to the proximal portion of the cannula, the entry guide tube including a plurality of channels for passage of a plurality of instrument shafts, wherein the entry guide tube is rotatably driven relative to the proximal portion of the cannula by rotation of at least one instrument shaft about a longitudinal axis of the entry guide tube. | 11-17-2011 |
| 20110282357 | SURGICAL SYSTEM ARCHITECTURE - Robotic surgical systems are provided. In one embodiment, the system includes a setup link for locating a remote center of motion for the robotic surgical system; a manipulator arm assembly including an active proximal link and an active distal link, the proximal link operably coupled to the setup link; and a plurality of instrument manipulators operably coupled to a distal end of the distal link, the plurality of instrument manipulators rotatable about an instrument manipulator assembly roll axis. A cannula mount is movably coupled to a proximal end of the distal link, and a cannula is coupled to the cannula mount, the cannula having a longitudinal axis substantially coincident with the instrument manipulator assembly roll axis. The system further includes an entry guide tube at least partially within the cannula, the entry guide tube rotatable about the longitudinal axis of the cannula. | 11-17-2011 |
| 20110282358 | SURGICAL SYSTEM INSTRUMENT MOUNTING - Robotic surgical systems and methods of coupling a surgical instrument to a manipulator arm are provided. In one embodiment, a system includes a base; a setup link operably coupled to the base, the setup link locating a remote center of motion for the robotic surgical system; a proximal link operably coupled to the setup link; and a distal link operably coupled to the proximal link. A plurality of instrument manipulators are rotatably coupled to a distal end of the distal link, each of the instrument manipulators including a plurality of actuator outputs distally protruding from a distal end of a frame. | 11-17-2011 |
| 20110288669 | MASS PRODUCTION OF INDIVIDUALIZED MEDICAL DEVICES - A plurality of individual medical devices is created that define a medical device family. Within the family of medical devices, each of the plurality of medical devices has at least one dimension that, within an acceptable tolerance, is substantially equal to the same dimension of another of the plurality of medical devices. Thus, for each medical device in the family, another, corresponding medical device has at least one substantially similar dimension. For example, a first medical device may have a first value for a dimension and a second medical device may have a second value for the same dimension that is equal to one of the sum of the second dimension and the acceptable tolerance or the difference between the second dimension and the acceptable tolerance. Thus, each of the plurality of medical devices varies from another of the plurality of medical devices by the acceptable tolerance. | 11-24-2011 |

| 20090067619 | Modular Multiplier - Modular multiplication of two elements X(t) and Y(t), over GF(2), where m is a field degree, may utilize field degree to determine, at least in part, the number of iterations. An extra shift operation may be employed when the number of iterations is reduced. Modular multiplication of two elements X(t) and Y(t), over GF(2), may include a shared reduction circuit utilized during multiplication and reduction. In addition, a modular multiplication of binary polynomials X(t) and Y(t), over GF(2), may utilize the Karatsuba algorithm, e.g., by recursively splitting up a multiplication into smaller operands determined according to the Karatsuba algorithm. | 03-12-2009 |
| 20090125514 | Sequence Matching Algorithm - Sequence alignment techniques are disclosed. In one embodiment, a sparse data structure is constructed that represents respective character positions of matching character sets in input sequences. This sparse data structure may take a variety of forms, including a “tree of trees.” Once constructed, each match is linked to at most one other match using a local application of a predetermined algorithm (e.g., a Smith-Waterman-type scoring algorithm). The links between matches are analyzed and a possible alignment or set of alignments is produced. | 05-14-2009 |
