    摘要： A multifunction adaptor for an open-ended catheter that allows placement of the catheter while minimizing the risk of air embolism or blood loss through the open (proximal) end of the catheter body. In one variation, the design allows passage of a standard guidewire for “over-the-guidewire” placement techniques and a connection for catheter flushing using a standard syringe. In another variation, the multifunction adaptor is configured for coupling a tunneler to the proximal end of a catheter.

    摘要： A multi-lumen catheter defined by at least two separate tip sections distal to a dividing point includes strategic placement of openings in the tip sections to facilitate fluid flow and minimize typical problems associated with catheters. In a multi-lumen catheter having tip sections with a releasably joined or splittable region, the bond strength between the tip sections is varied along their length such that an increasing separation force is required to separate the tip sections from one another distal to the dividing point. Delivery of a multi-lumen catheter is improved with respect to both sheathed and non-sheathed delivery methods, in which a friction reducing structure is provided on either the catheter, delivery sheath or both to provide a buffer for a sheathed delivery and in which a unique guidewire aperture or additional lumen is provided in at least one of the tip sections for a non-sheathed delivery.

    摘要： An apparatus for use downhole is disclosed that, in one configuration includes a downhole tool configured to operate in an active position and an inactive position and an actuation device, which may include a control unit. The apparatus includes a telemetry unit that sends a first pattern recognition signal to the control unit to move the tool into the active position and a second pattern recognition signal to move the tool into the inactive position. The apparatus may be used for drilling a subterranean formation and include a tubular body and one or more extendable features, each positionally coupled to a track of the tubular body, and a drilling fluid flow path extending through a bore of the tubular body for conducting drilling fluid therethrough. A push sleeve is disposed within the tubular body and coupled to the one or more features. A valve assembly is disposed within the tubular body and configured to control the flow of the drilling fluid into an annular chamber in communication with the push sleeve; the valve assembly comprising a mechanically operated valve and/or an electronically operated valve. Other embodiments, including methods of operation, are provided.

    摘要： A method of making an access port, includes providing a port body defining a fluid cavity, positioning a septum over the fluid cavity, and securing the septum to the port body. The septum includes a lower portion having a first diameter, an upper portion joined to the lower portion at a juncture, the upper portion having a second diameter less than the first diameter at the juncture, and a plurality of palpation features joined to the upper portion. Each of the palpation features includes a first end adjacent a central axis of the septum, and a second end extending radially outward, overlapping the juncture.
