Patent number: 7530953Abstract: An electrical connector is described. In one implementation, the connector includes a female portion including one or more electrical contacts and a male portion including one or more electrical contacts. The female portion and the male portion each have a self-orientating geometry that allows the male portion to be mated with the female portion in any rotational position along 360 degrees of rotation. When mated, the electrical contacts of the female portion mate with corresponding one or more electrical contacts of the male portion to form one or more electrical connections between two electronic components.Type: GrantFiled: January 31, 2007Date of Patent: May 12, 2009Assignee: Boston Scientific Neuromodulation CorporationInventors: E.

Publication number: 20080167560Abstract: The present invention provides self-aligning rotational connectors. In an non-limiting embodiment, a catheter system comprises a catheter connectable to a drive unit. The catheter includes a rotator, and at least one orientating feature extending proximally from the rotator, and configured to be inserted into an orienting slot of a shaft connector of the drive unit. When the orienting feature is inserted into the slot of the shaft connector, the slot transmits torque from the shaft connector to the orientating feature, and therefore the rotator of the catheter. Electrical contacts are provided on the rotator and the shaft connector, wherein the contacts of the rotator are properly aligned with and engage the contacts of the shaft connector. Further, the shaft connector has a slopping surface that slops downward into the slot for automatically aligning the rotator rotationally with the shaft connector during insertion of the catheter into the drive unit.Type: ApplicationFiled: January 9, 2007Publication date: July 10, 2008Inventor: Peter Thornton

Publication number: 20060285340Abstract: A recessed luminaire includes a housing with one or more vents. The one or more vents may be coupled to a ventilation system so that the luminaires can provide ventilation as well as illumination. The housing supports a potentially flammable diffuser with one or more fusible links. When subjected to elevated temperatures, at least a portion of the one or more fusible links will soften so the diffuser may drop down.Type: ApplicationFiled: June 17, 2005Publication date: December 21, 2006Applicant: Focal Point LLCInventor: Peter Thornton

Patent number: 6953471Abstract: A medical device for filtering embolic material. The device comprises a cannula having a lumen, the lumen communicating with a port at the distal end. A port is located on an outer surface of the cannula adjacent a distal region of the cannula, the port having a passage extending distally and communicating with a distal opening in the port. A filter is removably insertable through the passage of the port, the filter comprising a flexible tubular member, a flexible shaft extending through the tubular member, and an expansion frame mounted on the distal end of the shaft. A filter mesh attached to the expansion frame. The expansion frame may optionally include a cantilever beam to support the far end of the frame, and in certain cases the cantilever beam is flexible to avoid scraping the vessel wall during use. Methods of use are also described.Type: GrantFiled: February 7, 2002Date of Patent: October 11, 2005Assignee: Edwards Lifesciences CorporationInventors: Richard Lilly, Richard O.

Patent number: 6811559Abstract: An intravascular device for venting an inflatable chamber and methods for using the device are disclosed. The intravascular device generally includes three components, namely a catheter or cannula, an inflatable member, and a selective degassing element. The inflatable member is typically a balloon. The catheter or cannula is typically hollow with a first lumen extending between an inflation port and the interior of the inflatable member and a second lumen extending between the interior of the inflatable member and an exhaust port. The selective degassing element is typically positioned between the inflatable member and the exhaust port and occupies the entire cross-sectional area of the second lumen. When in a closed position, the selective element prevents the passage of liquid from the interior of the inflatable member, through the exhaust port. When in an open position, the selective element permits gas entrained within the inflatable member to be expelled from the device, via the exhaust port.Type: GrantFiled: March 5, 2002Date of Patent: November 2, 2004Assignee: Edwards Lifesciences CorporationInventor: Peter Thornton

Publication number: 20020128679Abstract: A shunt and method of use for maintaining distal blood flow during an arteriotomy procedure is disclosed. The shunt includes first and second tubular members having proximal ports, distal ports, and lumens therebetween. The distal port of the second tubular member is adapted for releasable attachment to the proximal port of the first tubular member. A second lumen merges and communicates at its distal end with the lumen of the first tubular member and includes a hemostatic valve attached to its proximal end. In using the apparatus for performing open endarterectomy, a filter device is inserted into the vessel and deployed downstream the region of interest in the internal carotid artery. The distal end of the shunt is advanced over the filter device and secured onto the artery. The proximal end of the shunt is inserted upstream the region of interest, typically in the common carotid artery.Type: ApplicationFiled: March 8, 2001Publication date: September 12, 2002Applicant: EMBOL-X, Inc.Inventors: Roman Turovskiy, Jobert Balceta, Ross S.

Patent number: 5741320Abstract: A steerable catheter comprising a resilient body member, a manipulation handle attached to the proximal end of the body member, a control wire extending from the handle to the distal end of the catheter for deflection control, and a pulley mechanism for controlling the movement of the control wire. Longitudinal movement of a slide element in the handle causes movement of the control wire and control over the deflection of the distal end of the catheter. The pulley mechanism is connected between the slide element and the control wire to provide greater mechanical advantage to effect deflection of the body member while enhancing deflection control resolution. A stiffening member is also disposed in the catheter body member and its position is controlled by the rotational motion of the slide element. The position of the pulley mechanism is not affected by rotational motion of the slide element.Type: GrantFiled: May 2, 1995Date of Patent: April 21, 1998Assignee: Heart Rhythm Technologies, Inc.Inventors: Peter Thornton, Tracy D.
