Patent number: 8796636Abstract: A neutron detection system includes a neutron scintillator having a thickness greater than an optimal thickness and less than twice the optimal thickness. The system includes a first layer of wavelength shifting fiber optic elements positioned on a first side of the neutron scintillator. Adjacent fibers of the first layer pass light to distinct photo-multiplication devices. The system further includes a second layer of wavelength shifting fiber optic elements positioned on a second side of the neutron scintillator. Adjacent fibers of the second layer pass light to distinct photo-multiplication devices. The two layers may share photo-multiplication devices or use different sets of photo-multiplication devices.

Patent number: 5865800Abstract: For achieving, e.g., an improved electrophysiology catheter for examination of the heart, or a catheter accessing the brain, the invention, in one aspect, features an elongated wound wire coil extending through the hollow catheter body of a steerable catheter. The coil is constructed and arranged to enable the catheter body to withstand reactive compressive load without distortion during application of tension on the pull wire and to transmit torque from the proximal to the distal tip portion of the catheter to enhance fidelity of rotational positioning of the distal tip in response to rotational orientation of the proximal portion of the catheter. The coil is shown in frictional torque-transmitting relationship with the interior of the hollow shaft substantially along the common length of the catheter body when the catheter is bent. Steerable catheters with augmented throw for one-handed operation and important improvements in construction features are also shown.Type: GrantFiled: October 8, 1996Date of Patent: February 2, 1999Assignee: Boston Scientific CorporationInventors: Thomas F. Mirarchi, Josef V. Koblish, Kulbir S. Hunjan, Craig R. Kline, Thomas H. Peterson

Patent number: 5658296Abstract: A method for forming a surgical retrieval basket includes cold forming a section of each of a plurality of axially extending wires in a predetermined shape. Securing the wires together proximate the sections with a cavity defined between the sections of the plurality of the wires forms an enlarged portion of a surgical retrieval basket. The retrieval basket comprises a plurality of wires normally encased in a compact form within a sheath whereupon displacement of the sheath to free a portion of the wires enables the wires to form an enlarged retrieval basket. The wires forming the retrieval basket are cold formed in a predetermined shape and are secured together in a predetermined fashion to define the retrieval basket.Type: GrantFiled: November 21, 1994Date of Patent: August 19, 1997Assignee: Boston Scientific CorporationInventors: James S.

Patent number: 5376094Abstract: A medical device has a body, an actuating member mounted to move relative to the body, a working element, and an elongated force-transmitting member capable of transmitting actuating force between the actuating member and the working element. The force-transmitting member includes a flexible cable portion, the force-transmitting member is attached, on one side of the cable portion, to the body and associated in a driving relationship on the opposite side of the cable portion with the working element. According to the invention the actuating member includes a pulley surface bodily movable therewith, the cable portion is trained about the pulley surface such that movement of the actuating member a given distance, relative to the body, causes the working element to move a substantially greater distance than the given distance. Another aspect of the invention is a medical snare with the above features.Type: GrantFiled: August 19, 1993Date of Patent: December 27, 1994Assignee: Boston Scientific CorporationInventor: Craig R.
