20150089785 | METHOD OF ATTACHING AN ELEMENT TO A DRIVE SHAFT - A method for attaching a head to a drive shaft may include winding a wire to create a drive shaft, selecting a head, forming a tapered tip on a distal end of the drive shaft, placing the head on the tapered tip such that a distal end of the tapered tip extends from a distal end of the head, engaging the distal end of the tapered tip and turning down the drive shaft to create a turned down portion, advancing the head proximally over the turned down portion, and disengaging the distal end of the tapered tip wherein the drive shaft frictionally engages the head. | 04-02-2015 |
20150094745 | ATHERECTOMY DEVICE WITH ECCENTRIC CROWN - An atherectomy device may include an elongated, flexible drive shaft having a distal end for insertion into a vasculature of a patient and having a proximal end opposite the distal end remaining outside the vasculature of the patient, a handle coupled to the proximal end of the drive shaft for controlling the drive shaft, and a head arranged proximate the distal end of the drive shaft wherein the head may include a middle portion having a substantially uninterrupted outer surface and substantially conically-shaped first and second end portions, wherein the middle portion and substantially conically-shaped end portions all have a bore extending therethrough adapted to frictionally engage a drive shaft. | 04-02-2015 |

20120178333 | Bi-modal Poly-alpha-olefin Blend - A low viscosity, high tensile strength polymer having a bi-modal molecular weight distribution is produced using a combination of high molecular weight polymer and low molecular weight polymer. The polymer chains have a high content of meso dyads that results in a greater amount of crystalline regions when the polymer is solidified. The low molecular weight chains provide high flow characteristics when the polymer is molten. The process for producing the high content of meso dyads includes the use of an external donor catalyst during the reaction. | 07-12-2012 |

20080306194 | Hot-Melt Adhesive Compositions Based on Olefin Co-Polymers - The present invention relates to a new type of polyolefin based hot-melt adhesive and methods for their production. More particularly, it relates to a new type of hot-melt adhesive comprising propylene co-polymers and possessing a favorable balance of cohesive strength, adhesion properties, and processibility, which render them especially well-suited for some hot-melt adhesive applications, for example, as elastic attachment adhesives. | 12-11-2008 |

20110301918 | DATA ACQUISITION FOR POSITRON EMISSION TOMOGRAPHY - A method for estimating the start time of an electronic pulse generated in response to a detected event, for example the start time for pulses received in response to photon detection in positron emission tomography, includes providing a detector that detects an external event and generates an electronic analog pulse signal. A composite reference pulse curve is calculated to represent analog pulse signals generated by the detector. Upon receiving an analog pulse signal, it may be filtered, and then digitized, and normalized based on the area of the digital signal. Using at least one point of the normalized digital pulse signal, the composite reference pulse curve shape is used to estimate the pulse start time. | 12-08-2011 |
