Patent number: 8414482Abstract: An embolic protection device for use in a patient's blood vessel, such as the aorta, has an approximately cylindrical outer structure made of a filter mesh material and an approximately conical inner structure also made of a filter mesh material. On the downstream end of the embolic protection device, the wider end of the conical inner structure is joined to the cylindrical outer structure. The upstream end of the embolic protection device is open for blood to flow between the conical inner structure and the cylindrical outer structure. The space between the conical inner structure and the cylindrical outer structure defines a collection chamber for captured emboli. The narrow upstream end of the conical inner structure has a catheter port with a resilient seal that is sized for passage of a catheter shaft. The filter mesh material may be self-supporting or it may be supported on a resilient-framework or an inflatable framework.Type: GrantFiled: January 4, 2012Date of Patent: April 9, 2013Assignee: Emboline, Inc.Inventor: Amir Belson

Patent number: 8388523Abstract: A portable medical diagnostic instrument includes an instrument head and a handle portion having an open-ended receiving cavity. A compact illuminator defined by a housing retaining a miniature light source and a power supply is releasably fitted within the open-ended receiving cavity of the handle portion wherein the light source of the illuminator is optically coupled with the instrument on assembly therewith. The handle portion can be integral with the instrument or releasably attached. The handle portion according to at least one version is made from a plastic or other suitable material, permitting disposability and/or single patient use. In one version, the handle portion is flexibly deformable, at least partially, to facilitate release of the portable illuminator.Type: GrantFiled: June 3, 2009Date of Patent: March 5, 2013Assignee: Welch Allyn, Inc.Inventors: Robert L. Vivenzio, Raymond A. Lia, Ian K. Edwards, Thaddeus Wawro, Steven R. Slawson

Patent number: 8374683Abstract: A medical instrument including a probe adapted to be inserted into an orifice of an animal's body. The instrument includes an emitter of electromagnetic radiation that is sensed by a sensor mounted on the probe. The sensor can then determine, by variations in the amount of radiation received from the emitter, whether a probe cover is mounted over the probe. A sensor can also be used to determine whether the walls of the body orifice block the radiation received from the emitter, thereby indicating position of the sensor, and thus, the probe within the orifice. A special probe cover is disclosed, and methods of using the medical instrument are also disclosed.Type: GrantFiled: December 30, 2009Date of Patent: February 12, 2013Inventors: Ray D. Stone, David E. Quinn, John A. Lane

Patent number: 8221315Abstract: The present invention discloses devices and methods for performing intravascular procedures with out cardiac bypass. The devices include various embodiments of temporary filter devices, temporary valves, and prosthetic valves. The temporary filter devices have one or more cannulae which provide access for surgical tools for effecting repair of the cardiac valves. A cannula may have filters of various configurations encircling the distal region of the cannula, which prevent embolitic material from entering the coronary arteries and aorta. The temporary valve devices may also have one or more cannulae which guide the insertion of the valve into the aorta. The valve devices expand in the aorta to occupy the entire flow path of the vessel. In one embodiment, the temporary valve is a disc of flexible, porous, material that acts to filter blood passing therethrough. A set of valve leaflets extend peripherally from the disc.Type: GrantFiled: April 26, 2005Date of Patent: July 17, 2012Assignee: Medtronic, Inc.Inventors: Gregory H.
