| 20120004629 | SUBDURAL EVACUATION PORT ASPIRATION DEVICE - A subdural evacuation port aspiration device including a subdural evacuation portion and a port aspiration portion. The subdural evacuation portion includes a rigid tubular portion having a central axis, a threaded exterior surface, and a pair of wings extending outwardly in substantially opposite directions from the tubular portion. The port aspiration portion includes a first segment and a second segment extending in separate directions from the subdural evacuation portion, the first segment configured to receive an aspiration device and the second segment configured to connect to a negative pressure source. The subdural evacuation portion and the port aspiration portion are uniformly formed as a single rigid unit. | 01-05-2012 |
| 20110282264 | METHOD OF DRAINING CEREBROSPINAL FLUID - A method of draining cerebrospinal fluid from a human brain. The method includes providing a drainage catheter having a proximal end and a distal end. The drainage catheter has a plurality of openings formed therein. The plurality of openings includes a first opening, a second opening, and a most proximal opening. The second opening is disposed closer to the distal end than the first opening. A cross-sectional area of the first opening is less than a cross-sectional area of the second opening. The distal end of the drainage catheter is inserted into a human brain. Cerebrospinal fluid is drained from the human brain. The cerebrospinal fluid passes into the drainage catheter through the plurality of openings and out of the drainage catheter through the proximal end. A rate at which the cerebrospinal fluid passes through the drainage catheter is controlled to maintain intracranial pressure within a selected range. | 11-17-2011 |
| 20090312779 | Surgical Cutting Instrument With Near-Perimeter Interlocking Coupling Arrangement - A blade coupling mechanism for a hand-held surgical cutting instrument includes a first coupling member including a first blade-contacting surface and a first outer perimeter sidewall adjacent the first blade contacting surface. It also includes a second coupling member including a second blade-contacting surface facing the first blade-contacting surface of the first coupling member. The second coupling member includes a second outer perimeter sidewall adjacent the second blade contacting surface. The second blade-contacting surface and the second outer perimeter sidewall meet to define an outer edge. The second coupling member including a bore through the second blade contacting surface. The bore and the second blade contacting surface meeting to define an inner edge. Blade-engaging protrusions project from at least one of the first and second blade-contacting surfaces. The protrusions are spaced closer to the outer edge than the inner edge. | 12-17-2009 |
| 20090312762 | Micro-Saw Blade for Bone-Cutting Surgical Saws - A surgical cutting blade for cutting bone material when the blade is coupled to a hand-held surgical saw having protrusions extending therefrom that interface with the cutting blade. The cutting blade includes a distal end comprising a plurality of cutting teeth and a shank portion adjacent the distal end. It also includes a proximal end adjacent the shank portion. The proximal end is shaped to attach to the surgical saw and includes an upper substantially planar surface and a lower substantially planar surface and a side edge extending between the upper and lower planar surfaces. The side edge at least in part defines an outer perimeter extending about the proximal end. The outer perimeter includes a plurality of indentations forming openings configured to receive and interface with the protrusions of the surgical saw in a manner that the protrusions cooperatively impart motion to drive the blade. | 12-17-2009 |
| 20090312761 | Surgical Cutting Instrument with Dual Surface Interlocking Coupling Arrangement - A hand-held surgical cutting instrument for cutting bone material with a surgical micro-saw blade has a plurality of openings formed therein. The surgical cutting instrument includes a hand-graspable body for manipulating the cutting instrument and a blade coupling mechanism attached to the body and being configured to attach to the surgical micro-saw blade. The blade coupling mechanism includes a first coupling member including a first blade-contacting surface. The first blade-contacting surface has at least one first protrusion extending therefrom and is configured to engage a first opening in the surgical saw blade. The blade coupling mechanism includes a second coupling member including a second blade-contacting surface facing the first blade-contacting surface of the first coupling member. The second blade-contacting surface having at least one second protrusion extending therefrom and configured to engage a second opening in the surgical saw blade. | 12-17-2009 |
