摘要： A catheter insertion device is provided that comprises an elongate member defining a longitudinal axis. The elongate member is configured to be disposed on a catheter in one of a first configuration and a second configuration. The first configuration and the second configuration are different. The catheter insertion device is further configured to allow the elongate member to be selectively and repeatedly reconfigured between the first configuration and the second configuration while disposed on the catheter.

摘要： An introducer sheath for a medical device is provided. The sheath includes a deformable, elongate body disposed about a longitudinal axis. The body has proximal and distal ends and defines a lumen extending between the proximal and distal ends and configured to allow passage of the medical device therethrough. The body is configured to allow an electric current to pass radially between a space outside of the body and the lumen such that the position of the medical device within a patient can be monitored and electrogram readings from body tissues can be measured while the device is in the sheath. In some embodiments of the invention, the body may include a one or more apertures extending from the radially outer surface of the body to the lumen or a portion of the body may be made from a conductive and/or fluid permeable material.

摘要： A medical catheter includes a deflectable and compressible catheter shaft; a pull ring near a distal end of the catheter shaft; a distal tip that includes a tip element and a mounting shaft; and an attachment apparatus for securely attaching the distal tip to the catheter shaft, the attachment apparatus including a compression ring which compresses the catheter shaft and the mounting shaft together. The compression ring can be located around the catheter shaft to compress the catheter shaft against an outer surface of the mounting shaft, or within the catheter shaft to compress the catheter shaft outwardly against an inner surface of the mounting shaft. The medical catheter can be an ablation catheter, with the tip element being a tip electrode, and it can be an irrigated ablation catheter, with the distal tip including a fluid manifold.
