20090093802 | Systems and Methods for Transeptal Cardiac Procedures, Including Tissue Penetrating Members and Associted Methods - Systems and methods for transeptal cardiac procedures are disclosed. A method for treating a patient in accordance with a particular embodiment includes positioning a tissue penetrating guidewire adjacent to a cardiac septum, directing pulses of energy to the guidewire, and advancing the guidewire into and through the septum by moving the guidewire in a distal direction in a series of discrete steps. Individual steps can be of a predetermined distance measured outside the patient's body. The method can further include passing a catheter over the guidewire after the guidewire has passed through the septum. | 04-09-2009 |
20090118726 | Systems and Methods for Transeptal Cardiac Procedures, Including Tissue Sealing Members Associated Methods - Systems and methods for transeptal cardiac procedures are disclosed. A patient treatment device in accordance with a particular embodiment includes a catheter having a proximal end, a distal end, a working portion toward the distal end, and an electrical energy path coupleable to a source of electrical energy. The device can further include a tissue penetrating member carried by the catheter and an electrode device carried by the working portion of the catheter and movable along the tissue penetrating member. The electrode device can include a collapsible stranded conductive material coupled to the electrical signal path and being changeable between a deployed position and a stowed position. The conductive material can be elongated along a deployment axis when in the stowed position, and can be contracted along the deployment axis and expanded transverse to the deployment axis when in the deployed position. | 05-07-2009 |
20110087211 | TISSUE-PENETRATING GUIDEWIRES WITH SHAPED TIPS, AND ASSOCIATED SYSTEMS AND METHODS - Tissue-penetrating guidewires with shaped tips, and associated systems and methods are disclosed. A patient treatment system in accordance with one embodiment of the disclosure includes a tissue-penetrating guidewire that in turn includes a flexible segment having a distal portion and a proximal portion. The flexible segment is elongated along an elongation axis. A penetrating member is positioned at the distal portion and includes at least one blade segment having a tapered outer peripheral surface and an adjacent generally sharp edge. The blade segment extends to a distal end of the penetrating member to form a generally blunt tip. In operation, the guidewire can be connected to an electrical current source to deliver high frequency current to the penetrating member. | 04-14-2011 |
20110218503 | SYSTEMS AND METHODS FOR TRANSEPTAL CARDIAC PROCEDURES, INCLUDING ADJUSTABLE, SEPARABLE GUIDEWIRES - Systems and methods for transeptal cardiac procedures are disclosed. A patient treatment device in accordance with a particular embodiment includes an elongated intravascular guidewire that includes a first branch and a second branch fixedly secured relative to the first branch at a first location and releasably secured relative to the first branch at a second location. At least one of the first and second branches is movable relative to the other between a first position in which the first and second branches form a closed shape, and a second position in which the first and second branches form an open shape. A controller can be operatively coupled to the first and second branches to control (e.g., in a fixed increment manner or a continuously variable manner) a distance between a portion of the first branch and a portion of the second branch while the first and second branches form the closed shape. | 09-08-2011 |

20100143734 | Polymeric film with low blocking and high slip properties - A film includes first and second outer layers, a core layer, and first and second substrate layers, each layer including a polymer; at least one of the substrate layers includes an amidic wax, and at least one of the outer layers includes an amidic wax present in an amount of 1% to 50% of the amount of wax in the first and second substrate layers respectively. The wax can be blended with a transition metal salt of stearic acid, or ester of stearic acid. Alternatively, a film includes first and second outer layers, and a substrate layer, each layer including a polymer; at least one of the first outer layer, second outer layer, and substrate layer including a blend of an amidic wax, and a transition metal salt of stearic acid, or ester of stearic acid. | 06-10-2010 |
20120211150 | Method of Orienting A Polyester Film - The present invention includes a film having at least one outer layer comprising a glycol-modified polyester and a N,N′-bis(fatty) amide. In a further aspect, embodiments of the present invention include methods for preparing oriented films having an outer layer comprising a glycol-modified polyester and a N,N′-bis(fatty) amide. In one aspect, the present invention includes a method for the concurrent transverse orientation of two films having outer layers that each comprise a blend of a glycol-modified polyester and a N,N′-bis(fatty) amide. Further aspects provide for the machine direction orientation of having an outer layer comprising a glycol-modified polyester and a N,N′-bis(fatty) amide. | 08-23-2012 |
20140151258 | Polymeric Films Comprising Biodegradable Polyester or Copolymer Thereof - The presently disclosed subject matter is directed to a film comprising a blend of about 90% to 99% polyester and about 1% to 10% biodegradable aliphatic or aromatic polyester (by weight). It has been surprisingly discovered that polymeric films comprising the disclosed blend exhibit improved flexibility and impact strength compared to polyester films known in the art. Films with the disclosed blends also advantageously do not adversely affect recyclability of the film. The disclosed films can be used in a wide variety of areas, including (but not limited to) shrink sleeve applications. | 06-05-2014 |

20130034231 | Spatial audio processing - A spatial audio processing uses a matrix of channels and conditioning amplifiers. Four channels are created from two by using a left, right, mono and a differential amp. A timing gate is added and set to the bass frequency to switch the matrix. The matrix starts with channel one receiving the left program. On the next timing cycle, channel two receives the left program, while channel one receives the left rear program. Thereafter, channel three receives the right program and channel four receives the right rear program. This condition continues through the timing order until every channel has received all four programs and then repeats itself. The constant shift in program content eliminates standing waves in any area and opens up the sound in an area that becomes spatial or orbital. | 02-07-2013 |

20140334830 | System and Method for Generating A Frequency Modulated Linear Laser Waveform - A system for generating a frequency modulated linear laser waveform includes a single frequency laser generator to produce a laser output signal. An electro-optical modulator modulates the frequency of the laser output signal to define a linear triangular waveform. An optical circulator passes the linear triangular waveform to a band-pass optical filter to filter out harmonic frequencies created in the waveform during modulation of the laser output signal, to define a pure filtered modulated waveform having a very narrow bandwidth. The optical circulator receives the pure filtered modulated laser waveform and transmits the modulated laser waveform to a target. | 11-13-2014 |

20100016575 | BACTERIAL CELLULOSE-CONTAINING FORMULATIONS LACKING A CARBOXYMETHYL CELLULOSE COMPONENT - A method for the production of a bacterial cellulose-containing formulation that lacks a carboxymethyl cellulose component. The method includes providing a bacterial cellulose product, mixing the bacterial cellulose product with a polymeric thickener and/or a precipitation agent, lysing the bacterial cells from the bacterial cellulose product or the mixture of the bacterial cellulose product and the polymeric thickener or precipitation agent, and co-precipitating the resultant mixture with a water-miscible non-aqueous liquid. The resultant bacterial cellulose formulation includes at least one bacterial cellulose material and at least one polymeric thickener. The bacterial cellulose formulation, may be used in food compositions. | 01-21-2010 |
