20130060650 | METHOD AND A COMPUTER SYSTEM TO FACILIATE A PURCHASE OF AN ITEM ON A NETWORK-BASED MARKETPLACE - This invention relates to a method and a computer system to facilitate a purchase of an item on a network-based marketplace. A proposed bid is received from a potential buyer to an item, the proposed bid including identification data (ID) identifying the item and a proposed-price for the item ID. The proposed bid is processed so as to identify potential sellers selling the item ID via the network-based marketplace. The proposed bid is forwarded to the identified potential sellers, and in case a target seller selected from these potential sellers agrees on the proposed-price and thus an actual selling price for said item ID, an acknowledgement message is issued informing the potential buyer that the target seller has accepted the proposed-price to the item ID. | 03-07-2013 |

20110118854 | SUSPENSION LINER HAVING MULTIPLE COMPONENT SYSTEM - A residual limb suspension liner for a prosthesis has a first layer defined by a first elastomeric material and forms a continuous circumferential internal surface of the liner. The liner also includes a second layer defined by a second elastomeric material different from the first elastomeric material. The second layer has a first surface adjacent to and integrally joined to the first layer. The second layer has a variable radial thickness over an anterior aspect of the liner. | 05-19-2011 |
20130331952 | SUSPENSION LINER HAVING MULTIPLE COMPONENT SYSTEM - A suspension liner for a residual limb has a liner body with a plurality of anterior and posterior projections formed from a thickness of the liner body. Medial and lateral tendons are located between and correspond to profiles of the plurality of the anterior and posterior projections such that the medial and lateral tendons are located on opposed sides of the liner body relative to one another. The medial and lateral tendons flare circumferentially toward proximal and distal sections of the liner body. | 12-12-2013 |

20130053982 | SUSPENSION LINER WITH SEAL COMPONENT - A suspension liner is provided for use as an interface between a residual limb and a prosthetic socket. The liner has an elongate, generally conical liner body formed from at least one material segment that is at least radially elastically extensible from a relaxed non-extended condition and including proximal and distal end areas, and a seal component connected to the liner body and having an exterior surface defining at least one exterior seal protruding from the exterior surface and extending radially outwardly from the seal component relative to a longitudinal axis of the liner body. The at least one interior seal is located along an interior surface of the seal component and defines at least one blade extending obliquely toward the liner body. A portion of the seal component carrying the interior seal extends freely and is movable relative to the liner body. | 02-28-2013 |
20130211544 | VACUUM ASSISTED SUSPENSION SYSTEM - A vacuum assisted suspension system is used to increase or maintain negative pressure or vacuum in a sealed socket cavity as a socket and prosthetic limb attachment mechanism. The system includes a vacuum pump having a housing that defines an enclosed space to receive a fluid. At least one wall of the housing and at least one movable wall define a fluid compartment. The system includes a compression transfer element connected to the at least one movable wall and connected to a prosthetic foot. The compression transfer element causes the at least one movable wall of the fluid compartment to move and increase the volume of the fluid compartment in response to a compressive force on the prosthetic foot to draw in fluid from the prosthetic socket. In the absence of a compressive force, the volume of the fluid compartment decreases thereby expelling fluid out of the fluid compartment. | 08-15-2013 |
20130289741 | PROSTHETIC DEVICE, SYSTEM AND METHOD FOR INCREASING VACUUM ATTACHMENT - A prosthetic device, system and method is arranged to generate negative pressure inside a prosthetic socket. A pump mechanism is connected to a prosthetic foot and has a fluid chamber in fluid communication with the prosthetic socket during gait for drawing air from the prosthetic socket in step phase, and expelling air into the atmosphere in swing phase. The vacuum assisted suspension results in secure and intimate suspension as the negative pressure formed inside the prosthetic socket holds a residuum firmly to walls of the prosthetic socket. The vacuum is preferably formed at the distal area of the prosthetic socket, and sealed by a suspension liner having a seal component. | 10-31-2013 |

20150057763 | Variable Tensioned Prosthetic Device Including Continuously Elasticized Fabric - A prosthetic device includes first and second regions divided by a longitudinal line extending between the first and second ends of the device. The device has a continuously knit elasticized fabric layer including a first set of yarns located about a circumference of the device through the first and second regions. The fabric layer has different knit structures in the first and second regions to obtain different elasticity while sharing the first set of yarns so that the first region has a first elasticity, and the second region has a second elasticity greater than the elasticity of the first region. An elastomeric layer secures an interior surface of the fabric layer. | 02-26-2015 |
