Abstract: A biological fluid transport device comprises a cutwater at the junction of at least two blood flow paths. The cutwater is substantially straight, substantially vertical, or both. At least one of the fluid paths may be tubular, and in some embodiments all of the fluid paths are tubular. The shear sensitive fluid may be, without limitation, blood, blood-based combinations, cell culture media, cell suspensions, proteins, and microcapsule suspensions. The device may be part of an extracorporeal circuit (e.g., blood during heartlung bypass procedures or blood processing), but it need not be. Preferred embodiments of the device include, without limitation, kinetic pumps, mass transfer devices, filters, reservoirs, and heat exchangers.

Abstract: A shield located within an implantable medical lead may be terminated in various ways at a metal connector. The shield may be terminated by various joints including butt, scarf, lap, or other joints between insulation layers surrounding the lead and an insulation extension. The shield may terminate with a physical and electrical connection to a single metal connector. The shield may terminate with a physical and electrical connection by passing between an overlapping pair of inner and outer metal connectors. The metal connectors may include features such as teeth or threads that penetrate the insulation layers of the lead. The shield may terminate with a physical and electrical connection by exiting a jacket of a lead adjacent to a metal connector and lapping onto the metal connector.

Abstract: Grounding of a shield that is located in an implantable medical lead may be done in many ways. The shield may be grounded directly to tissue from the lead body at one or more points along the lead body. The pathway for grounding may be a direct current pathway or be capacitively coupled. The pathway for grounding may utilize an exposed or nearly exposed shield at one or more points along the lead body. A jacket forming the lead body may have an outer layer removed at these points to provide the RF pathway to ground. Alternatively, the jacket may be doped with conductive particles at these points. Metal conductors such as ring electrodes and/or lead anchors may be attached to the lead at one or more points to provide the RF pathway to ground.

Abstract: Grounding of a shield that is located in an implantable medical lead may be done in many ways. The ground pathway may couple to the shield at a point that is outside of a header of an implantable medical device to which the implantable medical lead is attached. The ground pathway may couple to the shield at a point that is within the header of the implantable medical device. The ground pathway may terminate at the metal can of the implantable medical device. As another option, the ground pathway may terminate at a ground plate that is mounted to the header. The ground pathway may be direct current coupled from the shield to the can or ground plate. Alternatively, the ground pathway may include one or more capacitive couplings that provide a pathway for induced radio frequency current.
