Abstract: An implantable device for treating hypervolemia includes an expandable chamber, a rigid chamber coupled to the expandable chamber, a first valve in fluid communication with both the expandable chamber and the rigid chamber, a second valve in fluid communication with the rigid chamber and an exterior of the implantable device, and an osmotic fluid. The expandable chamber includes a first semipermeable membrane. The rigid chamber includes a piston. The first valve has an open position to permit fluid flow between the expandable chamber and the rigid chamber. The second valve has an open position to permit fluid flow from the rigid chamber to the exterior of the implantable device. The osmotic fluid has a higher osmotic concentration than bodily fluid. The osmotic fluid is designed to absorb water from the bodily fluid through the first semipermeable membrane.

Abstract: Adjustable flow glaucoma shunts are disclosed herein. In one embodiment, for example, an adjustable flow shunt can include an outflow drainage tube having a proximal inflow region and a distal outflow region. The proximal inflow region can include aperture(s) defining a fluid inlet area positioned to allow fluid to flow therethrough. The shunt further comprises an inflow control assembly at the proximal inflow region. The inflow control assembly can include a control element configured to slidably engage the proximal inflow region and a spring element. The spring element is configured to be activated by non-invasive energy and, upon activation, slidably move the control element along the proximal inflow region such that (a) the one or more apertures are accessible and have a first fluid flow cross-section or (b) the one or more apertures are at least partially covered by the control element and have a second, different fluid-flow cross-section.

Abstract: A catheter set for forming a fistula between two adjacent blood vessels. The catheter set comprises two crossing catheters. Each crossing catheter comprising a catheter shaft defining a longitudinal axis and having a distal end section, a stabilizing element disposed in the distal end section of the catheter shaft, and a penetration tool for penetrating vessel walls of two adjacent blood vessels to form the fistula. The penetration tool is disposed within the catheter shaft and is movable between a retracted position and an advanced position. The stabilizing element comprises an expandable cage having a contracted configuration and a laterally expanded configuration. The expandable cage is suitable for snaring a guidewire when moving from the laterally expanded configuration to the contracted configuration.

Abstract: A brain disease treatment device includes a first tube and a second tube which has an outer diameter smaller than an inner diameter of the first tube, can be arranged in an inner cavity of the first tube, and can move in the inner cavity of the first tube. The first tube is inserted into a subarachnoid space of a patient and discharges cerebrospinal fluid present in the subarachnoid space out of a body of the patient through a space between the inner cavity of the first tube and the outer side of the second tube. The second tube is inserted into the subarachnoid space and injects fluid through an inner cavity of the second tube into the cerebrospinal fluid present in the subarachnoid space. An end portion of the second tube is exposable from an end portion of the first tube in a longitudinal direction of the first tube.

Abstract: Described embodiments include apparatus (28) that includes a shunt (26). The shunt includes a flared distal portion (40), a flared proximal portion (44), and an intermediate portion (42), disposed between the distal portion and the proximal portion. The apparatus further includes a constricting flexible longitudinal element (38) passing circumferentially along the intermediate portion of the shunt, configured to constrict the intermediate portion of the shunt, and one or more proximal-portion-collapsing flexible longitudinal elements (36) configured to collapse the proximal portion of the shunt. Other embodiments are also described.

Abstract: Systems, catheters, and methods for accessing and treating along the central nervous system are disclosed including sampling systems. An example sampling system may include a filter cassette designed to filter cerebrospinal fluid. The filter cassette may have an inlet region configured to be coupled to a catheter and configured to receive cerebrospinal fluid, one or more filters, and an outlet region configured to be coupled to an outlet of the catheter and to direct filtered cerebrospinal fluid to the catheter. A sampling port may be in fluid communication with the filter cassette. The sampling port may have a first end region configured to receive cerebrospinal fluid, a stopcock, a syringe port, and a second end region. The stopcock may be configured to shift between a first position where cerebrospinal fluid is directed from the first end region to the second end region and a second position where cerebrospinal fluid is directed from the first end region to the syringe port.

Abstract: A surgical or laparoscopic method of creating and maintaining an opening in the thoracic diaphragm of a patient. The method comprising the steps of creating an incision in the thoracic diaphragm and thereby creating an opening in the thoracic diaphragm, placing a diaphragm passing part in said opening created in the thoracic diaphragm, passing from the abdomen through the thoracic diaphragm and into the thorax; wherein the step of placing said diaphragm passing part comprises placing a force transferring part of the diaphragm passing part in contact with the thoracic diaphragm, the force transferring part being adapted to transfer force between the abdominal side of the thoracic diaphragm and the thoracic side of the thoracic diaphragm while sliding against the thoracic diaphragm.
