Patent number: 8177791Abstract: A sheath attached to a guide wire, a tubular shaft member slidable on the guide wire and a filtering assembly constricted within the sheath are movable in a vessel to a position distal to a lesion in the direction of fluid flow. The filtering assembly may be formed from a plurality of angularly spaced splines and a mesh disposed on the splines having properties of passing fluid in the vessel while blocking the passage of emboli in the fluid. The splines may be provided with shape memory for expanding against the wall of the vessel when released from constriction by the sheath. The sheath may be moved relative to the filtering assembly and the support member to release the filter for expansion against the vessel wall. An interventional device can be used to treat the lesion. Any emboli released into the vessel as a result of the interventional treatment are blocked by the filter member while fluid is allowed to pass there through.Type: GrantFiled: April 15, 2009Date of Patent: May 15, 2012Assignee: Abbott Cardiovascular Systems Inc.Inventors: Niraj A. Shah, Joann Heberer

Patent number: 6606647Abstract: A server routes one's incoming messages to his/her communication devices according to his/her routing preferences, and modifies the messages as needed. For example, the server can route an incoming page to one's email account and, if necessary, modify the page so that it is compatible with the email client. Thus, the server enables a number of diverse features such as: selection of routing topology (direct or indirect), translation of network restrictions, conditioning a synchronous communication for reception by an asynchronous device, message encryption, and callback or “buddy list” services.Type: GrantFiled: January 11, 1999Date of Patent: August 12, 2003Assignee: InfoSpace, Inc.Inventors: Niraj A. Shah, Ethan B. Hugg, Kevin L. Chestnut

Publication number: 20020029193Abstract: A method and system for facilitating the transfer of funds with a telephonic identifier are provided. A payor accesses a funding manager server utilizing a first identifier. The payor funds an account associated with the payor. Contemporaneously or subsequently, the payor designates an amount to transfer to a payee account associated with a second telephone number identifier. If the second telephone number corresponds to an active account in the funding system, the funding system transfers the funds to the payee account and notifies the payee via the telephone number. If the second telephone number does not correspond to an active account, the funding manager server obtains payee information utilizing a reverse look up and creates a payee account associated with the payee telephone number. The funding system transfers the designated funds to the payee account and notifies the payee how to retrieve the funds via the payee telephone number.Type: ApplicationFiled: August 31, 2001Publication date: March 7, 2002Applicant: InfoSpace, Inc.Inventors: Peeyush Ranjan, Niraj A.
