20130323062 | Propeller For Ventilator, With A Variable Blade Angle - A blower wheel comprises a hub, a guide and blades extending radially between the hub and the guide, each blade comprising a root at its junction with the hub and a head at the junction with the guide, each blade having a leading edge and a trailing edge between which, at each flattened cross section, a chord is defined. For each blade, in the radial direction from the root to the head, the pitch angle between the chord and the rotation axis of the wheel varies and the variation in the pitch angle between the root and the head has a point of inflexion between a first level and a second level. | 12-05-2013 |
20140056710 | Propeller For Ventilator, With A Variable Chord Length - A blower wheel comprises a hub, a guide and blades extending radially between the hub and the guide, each blade comprising a root at its junction with the hub and a head at the junction with the guide, each blade having a leading edge and a trailing edge between which, at each flattened cross section, a chord is defined. For each blade, between the root and the head, the length of the chord varies and the variation in the length of chord between the root and the head has a point of inflexion between two levels. | 02-27-2014 |

20090082811 | DEVICES AND METHODS FOR POSITIONING A SPINAL FIXATION ELEMENT - Methods for delivering a spinal fixation element to a surgical site are provided herein. More specifically, the method includes delivering a plurality of percutaneous access devices to a corresponding number of spinal locations, inserting a spinal fixation element through tissue, and manipulating the element through opposed sidewall openings formed in each access device. In an exemplary embodiment, the method can be optimized for position of large-scale fixation elements (e.g., greater than about 95 mm in length). In addition, a manipulation instrument configured to position such spinal fixation elements is also provided herein. | 03-26-2009 |
20100004695 | SYSTEM AND METHOD FOR MANIPULATING A SPINAL CONSTRUCT - A system and device for manipulating a spinal construct is provided. For example, the manipulation device can include a drive member to be disposed within a first surgical sleeve extending from a first vertebra, and a coupling member positioned adjacent a second surgical sleeve. In one embodiment, at least one of the drive member and the coupling member can be releasably engaged to an actuation mechanism. In one aspect, the actuation mechanism can include a floating and/or auto-locking pivot point thereby allowing a user to quickly and easily position the manipulation device relative to the adjacent surgical sleeves. Additionally, a method of manipulating spinal constructs is also provided. | 01-07-2010 |
20100179578 | SPINAL DISC PREPARATION TOOL - A spinal disc preparation tool is provided that includes an elongate shaft having an inner lumen extending therethrough along a longitudinal axis between proximal and distal ends thereof. A lower jaw is located on a distal end of the elongate shaft for receiving tissue and delivering tissue to the inner lumen, and an upper jaw is pivotally movable relative to the lower jaw. The tool can include various features to facilitate removal and/or collection of tissue. | 07-15-2010 |
20110152627 | Neural Tissue Retraction and Preservation Device - A self-retaining neural retraction clip, preferably having controlled retraction level and an off-set retraction means. This device can reduce operative site clutter to enhance disc access while providing consistent and stable dural retraction. | 06-23-2011 |
