Abstract:
Systems and methods for delivering a drug or other therapy over an extended period of time (e.g., several hours, days, weeks, months, years, and so forth) are disclosed herein, as are systems and methods for monitoring various parameters associated with the treatment of a patient. Systems and methods are also disclosed herein that generally involve CED devices with various features for reducing or preventing backflow.
Abstract:
Neurosurgical apparatus is described that comprises a guide device (60) and a neurosurgical instrument (40). The guide device includes a tube (66) for insertion into the brain of a subject and a head (64) attached to the proximal end of the tube (66) for affixing the guide device (60) to a hole formed in the skull. The head has a passageway (70) therethrough in communication with the bore of the tube (66) such that the bore of the tube and the passageway (70) through the head (64) define an internal channel through which a neurosurgical instrument (40) can be passed into the brain (10) of the subject. The neurosurgical instrument (40), such as a catheter, is for insertion to a desired brain target through the internal channel of the guide device (60). The apparatus comprises one or more sealing elements (50,72) for providing a substantially fluid tight seal between the internal channel of the guide device (60) and the exterior of the neurosurgical instrument (40) when inserted therein. This prevents fluid leakage from guide tube.
Abstract:
A medical fluid connector is described that comprises a first fluid connector portion (310) that can be connected to a second fluid connector portion (300). The first fluid connector portion (310) comprises a first locking member, a lumen (314) and a septum (312) for sealing the lumen. The second fluid connector portion (300) comprises a second locking member, a lumen (304) and a hollow needle (302) that is retained in and protrudes from the aperture at the end of the lumen (304). The variation in cross-sectional area of the fluid path through the fluid connector portion (300) is less than 1mm to reduce mixing effects. The use of such a connector for neurosurgical purposes is described.
Abstract:
A system for filtering or treating blood of a subject is provided herein. The system includes a bone port for establishing fluid communication with a bone marrow of the bone and a return port for returning blood from the bone marrow to a circulation of the subject. The system further includes a blood treatment or filtering device interposed between the bone and return ports thereby establishing a mini-circulatory system.
Abstract:
A surgical access assembly (100) is disclosed. The surgical access assembly comprises an outer sheath (102) and an obturator (104). The outer sheath and obturator are configured to be delivered to an area of interest within the brain. Either the outer sheath or the obturator may be configured to operate with a navigational system to track the location of either device within the brain.
Abstract:
Some introducer tools for bone portals have a handle coupled to a driving member by a force-limiting coupling. A bone portal comprising a bone-penetrating portion and a bone stop may be driven to a desired depth in bone when the force-limiting coupling allows application of force to the bone portal that is sufficient to drive the bone-penetrating portion of the portal into the bone but not sufficient to drive the bone stop significantly into the bone. Bone portals of various types are described herein. Various configurations for stylets suitable for use in introducing bone portals or otherwise penetrating bone and methods for inserting bone portals are also described herein.
Abstract:
A breakaway connector for use with a medical (e.g., catheter) or other fluid system. The connector may include two couplers that engage one another via a substantially frictionless retention device. In one embodiment, the retention device includes a biased cylindrical roller attached to one coupler that contacts an outer surface of the other coupler. The outer surface may include a grooved surface to receive the roller when the couplers are fully attached.
