Stimulus regimens for cardiovascular reflex control

InactiveUS6985774B2Reduces excessive blood pressure ,Minimize their deleterious effectSpinal electrodesStentsNervous systemHormone
Devices, systems and methods by which the blood pressure, nervous system activity, and neurohormonal activity may be selectively and controllably reduced by activating baroreceptors. A baroreceptor activation device is positioned near a baroreceptor, for example a baroreceptor in the carotid sinus. A control system may be used to modulate the baroreceptor activation device. The control system may utilize an algorithm defining a stimulus regimen which promotes long term efficacy and reduces power requirements / consumption.

Mapping methods for cardiovascular reflex control devices

Devices, systems and methods by which the blood pressure, nervous system activity, and neurohormonal activity may be selectively and controllably reduced by activating baroreceptors. A baroreceptor activation device is positioned near a baroreceptor, preferably in the carotid sinus. A mapping method permits the baroreceptor activation device to be precisely located to maximize therapeutic efficacy.

Methods, systems, and kits for lung volume reduction

Lung volume reduction is performed in a minimally invasive manner by isolating a lung tissue segment, optionally reducing gas flow obstructions within the segment, and aspirating the segment to cause the segment to at least partially collapse. Further optionally, external pressure may be applied on the segment to assist in complete collapse. Reduction of gas flow obstructions may be achieved in a variety of ways, including over inflation of the lung, introduction of mucolytic or dilation agents, application of vibrational energy, induction of absorption atelectasis, or the like. Optionally, diagnostic procedures on the isolated lung segment may be performed, typically using the same isolation / access catheter.

Electrode designs and methods of use for cardiovascular reflex control devices

Devices, systems and methods by which the blood pressure, nervous system activity, and neurohornonal activity may be selectively and controllably reduced by activating baroreceptors. A baroreceptor activation device is positioned near a baroreceptor, preferably in the carotid sinus. The baroreceptor activation device may utilize electrodes to activate the baroreceptors. The electrodes may be adapted for connection to the carotid arteries at or near the carotid sinus, and may be designed to minimize extraneous tissue stimulation.

Multi-pixel methods and apparatus for analysis of defect information from test structures on semiconductor devices

Disclosed is a method for detecting electrical defects on test structures of a semiconductor die. The test structures includes a plurality of electrically-isolated test structures and a plurality of non-electrically-isolated test structures. The test structures each has a portion located partially within a scan area. The portion of the test structures located within the scan area is scanned to obtain voltage contrast images of the test structures' portions. In a multi-pixel processor, the obtained voltage contrast images are analyzed to determine whether there are defects present within the test structures. In a preferred embodiment, the multi-pixel processor operates with pixel resolution sizes in a range of about 25 nm to 200 nm. In another aspect, the processor operates with a pixel size nominally equivalent to two times a width of the test structure's line width to maximize throughput at optimal signal to noise sensitivity. A computer readable medium having programming instructions for performing the above described methods is also disclosed.

Surgical fasteners, applicator instruments, and methods for deploying surgical fasteners

A surgical fastener for securing a prosthetic device to tissue includes a first leg having a distal end, a proximal end, and a first insertion tip at the distal end of the first leg, and a second leg including a distal end, a proximal end, and a second insertion tip at the distal end of the second leg. A bridge connects the proximal ends of the first and second legs for forming a closed end of the surgical fastener. The first insertion tip has a first insertion tool seating surface, and the second insertion tip has a second insertion tool seating surface. The first insertion tool seating surface is closer to the distal end of the first leg than the proximal end of the first leg, and the second insertion tool seating surface is closer to the distal end of the second leg than the proximal end of the second leg. The first and second legs extend along respective longitudinal axes, and the first and second insertion tips are skewed outwardly relative to the respective longitudinal axes.
