Publication number: 20220016402Abstract: A system includes a first port comprising a first inlet, a first outlet, a first fluid pathway extending from the first inlet to the first outlet, a second inlet, a second outlet, and a second fluid pathway extending from the second inlet to the second outlet. The system further includes one or more CSF catheters having a first lumen, a first distal opening in fluid communication with the first lumen, a second lumen, and a second distal opening in fluid communication with the second lumen. The one or more CSF catheters are, or are configured to be, operatively coupled with the first implantable device such that the first lumen is in fluid communication with the first fluid pathway and the second lumen is in fluid communication with the second fluid pathway.

Patent number: 9580494Abstract: Methods, agents and devices for treating a patient to reduce accumulation of certain proteins in the brain are described. Such proteins include amyloid beta (A?), and the methods, agents and devices are useful for reducing the accumulation of A?, which is a principal constituent of the plaques associated with such diseases as Alzheimer's disease (AD). Antibodies to A?, when delivered systemically or directly into the central nervous system, improve cognitive deficits in a transgenic mouse model of AD. However, unlike peripheral antibodies to A?, which increased cerebral vascular plaques and hemorrhages, direct central administration did not result in such an increase cerebral vascular plaques and hemorrhages.Type: GrantFiled: May 22, 2015Date of Patent: February 28, 2017Assignee: Medtronic, Inc.Inventors: Lisa Lynn Shafer, Deepak Ramesh Thakker

Patent number: 7769442Abstract: Stimulation of one or more neurons of the sympathetic nervous system, including the splenic nerve, is provided to attenuate an immune response, including an inflammatory immune response. Devices such as pulse generators and drug pumps may be used to stimulate the sympathetic nervous system to attenuate an immune response. Systems optionally having one or more sensors and operator instructions may also be used. In specific examples, stimulation of the splenic nerve of pigs with a pulse generator is shown to be safe and effective in attenuating a lipopolysaccharide-induced immune response.Type: GrantFiled: August 29, 2006Date of Patent: August 3, 2010Assignee: Medtronic, Inc.Inventor: Lisa Lynn Shafer

Publication number: 20100030196Abstract: A system includes (i) a medium having a solid support to which an antibody directed to target molecule is bound, (ii) a reservoir for containing the medium, (iii) a first catheter, and (iv) a second catheter. The first catheter has a proximal end portion, an opening for removal of cerebrospinal fluid from a subject, and a lumen extending from the proximal end portion to the opening. The first catheter is operably couplable to the reservoir such that fluid is capable of flowing from the lumen to the reservoir. The second catheter has a proximal end portion, a delivery region for returning cerebrospinal fluid to the subject, and a lumen extending from the proximal end portion to the delivery region. The second catheter is operably couplable to the reservoir such that fluid is capable of flowing from the reservoir to the lumen.Type: ApplicationFiled: July 29, 2009Publication date: February 4, 2010Applicant: MEDTRONIC, INC.Inventors: Keith Hildebrand, Lisa Lynn Shafer, Deepak Ramesh Thakker
