Patent CA-2361097-C (CA)
Title: Closed loop catheter coolant system
Inventor: LALONDE JEAN-PIERRE
IPC: A61F7/00
Filed: 2000-01-25
Granted: 2007-05-29
Abstract: A coolant system for a cryoablation or treatment probe such as a mapping or ablation catheter, or a treatment wand, includes a compressor and condenser having a low pressure inlet side and a high pressur e outlet side, wherein the outlet side passes through a heat exchanger and is cooled by the inlet side and conditioned for injection to a catheter inlet. A vacuum return system connectable to the catheter outlet draws thermally expended coolant from the catheter and returns it to the low pressure inlet side. A motorized pressure regulator between the heat exchanger and the catheter inlet determines the pressure of coolant passing into the catheter and thus regulates the cooling rate for a selected mapping or ablation regimen. The low pressure compressor inlet supply preferentially conditions the pressurized coolant to ambient temperature or lower before injection into the catheter, allowing the coolant to travel through the body at ambient before expansion in the tip. In a preferred embodiment, a coolant reservoir feeds into the low pressure inlet side and receives a return flow of excess fluid from a branch off the outlet side of the compressor. The vacuum return assures that coolant does not leak into the blood stream, and preferably various check valves and bypass valves operate in the event of pressure build-up to return fluid to either the inlet or supply from different points along the loop. The coolant mixture preferably has a boiling point of approximately -60.degree. Fahrenheit at about 1-2 bar, and may be compressed to several hundred psi. The entire system is amenable to microprocessor control for providing ablation cooling cycles to operate the catheter tip in accordance with a selected protocol, and for effecting system functions such as recharging and venting of the supply, and shutting down during nonuse or upon occurrence of a fault condition.

Patent CA-2362449-C (CA)
Inventor: SYAGE JACK A
IPC: H01J49/10

Granted: 2008-10-28
Abstract: A monitor that can detect at least one trace molecule in a gas sample. The monitor may include a photoionizer (102) that is coupled to an electron-ionization mass spectrometer (100). The photoionizer (102) may ionize the gas sample at a wavelength(s) which ionizes the trace molecules without creating fragmentation. The inclusion of the electron-ionizer (106) may allow alternate or additional ionization to detect trace molecules not ionized by the photoionizer (102). The gas sample may be ionized at atmospheric pressure which increases the yield of the ionized trace molecules and the sensitivity of the mass spectrometer (100).

Title: Method for generating patient-specific implants
Inventor: LITSCHKO PETER
IPC: G05B19/4099
Filed: 2000-05-10
Granted: 2007-03-20
Abstract: The invention relates to a method for generating patient-specific implants from the results of an examination of a patient arising from an imaging method in medical technology. The aim of the invention is to generate an implant which is functionally and aesthetically adapted to the patient with a greater degree of precision, irrespective of the size, form and complexity of the defect, whereby said implant can be produced and operatively inserted into the patient over a short time period and in a simple manner. According to the invention, a virtual three-dimensional model of the patient which is formed from existing recorded (two-dimensional) image data of a patient known per se is compared with real medical reference data. Said comparison which is, for example, carried out using a data bank with test person data enables a reference model object which is most suited to the patient or closest to the patient model to be selected or formed and a virtual implant model is generated accordingly.      CNC control data is directly generated from the implant model which is generated virtually in the computer for program-assisted production of said implant.

Title: Method for 2d inversion of dual laterolog measurements
Inventor: YIN HEZHU
IPC: G01V3/00
Filed: 2001-09-25
Granted: 2012-05-01
Abstract: A 2D inversion of true formation resistivity from dual laterolog tool measurements is accomplished using a pre-calculated look-up table 104. An initial earth model is derived and divided into intervals 102. A 2D tool response is calculated in each interval using the earth model 108. Matching is checked between the calculated 2D tool response and the tool measurements 104. The following steps are iterated until the match is satisfactory. A 1D radial tool response is derived in each interval using the precalculated look-up table 105. Shoulder bed effects are approximated in each interval by subtracting the 1D radial tool response from the 2D tool response 106. A non-linear least square optimization is applied at boundaries of the intervals and local maximum and minimum values in the intervals to update the earth model 107.

Title: Verifiable secret shuffles and their application to electronic voting
Inventor: NEFF ANDREW C
IPC: H04L9/30
Filed: 2002-03-25
Granted: 2005-05-31
Abstract: We present a mathematical construct which provides a cryptographic protocol to (verifiably shuffle) a sequence of (k) modular integers, and discuss its application to secure, universally verifiable, multi-authority election schemes. The output of the shuffle operation is another sequence of (k) modular integers, each of which is the same secret power of a corresponding input element, but the order of elements in the output is kept secret. Though it is a trivial matter for the "shuffler" (who chooses the permutation of the elements to be applied) to compute the output from the input, the construction is important because it provides a linear size proof of correctness for the output sequence (i.e. a proof that it is of the form claimed) that can be checked by one or more arbitrary verifiers. The protocol is shown to be honest-verifier zeroknowledge in a special case, and is computational zeroknowledge in general. On the way to the final result, we also construct a generalization of the well known Chaum-Pedersen protocol for knowledge of discrete logarithm equality ([3], [2]). In fact, the generalization specializes (exactly) to the Chaum-Pedersen protocol in the case (k)=2. This result may be of interest on its own. An application to electronic voting is given that matches the features of the best current protocols with significant efficiency improvements. An alternative application to electronic voting is also given that introduces an entirely new paradigm for achieving (Universally Verifiable) elections.
