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 assembly includes a deflectable catheter shaft, a distal tip with tip element and a mounting shaft, and a pull ring assembly, the distal tip defining guide channels through which pull wires of the pull ring assembly pass such that the pull wires will initially extend from the pull ring toward the tip element and then loop back toward and through the catheter shaft and to a handle actuator. Pulling of the pull wires by the handle actuator to tilt the pull ring and deflect the catheter shaft will cause the pull ring to move toward tip element. The pull ring and tip element are thus interlocked. Stress forces on the connection joints between the pull wires and the pull ring will be dissipated, reducing the incidence of failure of the pull ring assembly. The medical catheter can be a non-irrigated ablation catheter wherein the tip element is a tip electrode, or an irrigated ablation catheter wherein the tip element is a tip electrode and a fluid manifold.
摘要翻译：医疗导管组件包括可偏转的导管轴，具有尖端元件的远侧尖端和安装轴以及拉环组件，所述远侧末端限定所述拉环组件的拉线通过所述引导通道，使得所述拉线将最初从拉环延伸到尖端元件，然后环绕回并穿过导管轴和手柄致动器。通过手柄致动器拉动拉线以使拉环倾斜并使导管轴偏转将导致拉环向尖端元件移动。因此拉环和尖端元件是互锁的。拉线和拉环之间的连接接头处的应力将消散，减少拉环组件故障的发生。医疗导管可以是非灌注消融导管，其中尖端元件是尖端电极，或灌注消融导管，其中尖端元件是尖端电极和流体歧管。

摘要： A splittable/peelable tubular body (2) of a catheter or sheath wherein the tubular body (2) has a splittable/peelable atraumatic tip (14) is disclosed. The atraumatic tip (4) is generally softer than the tubular body (2). The tubular body (2) and atraumatic tip (4) each comprise a peel mechanism longitudinally extending along their respective lengths. The peel mechanisms are formed by longitudinally extending regions of interfacial bonding (11) between first and second longitudinally extending strips (8, 10) of polymer material. Each strip (8, 10) forms at least a portion of an outer circumferential surface of the tubular body (2) and atraumatic tip (4). A region of stress concentration extends along the region of interfacial bonding. The stress concentration facilitates the splitting of the tubular body (2) and atraumatic tip (4) along their respective peel mechanisms.

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 catheter can be a non-irrigated 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.

摘要： A system for connecting a hemostasis valve to a splittable sheath includes an interface formed between a ledge on the proximal end of a cannula portion of the hemostasis valve and an engagement structure aligned with the handles of the splittable sheath. Pulling the handles to split the sheath likewise disengages the ledge from the engagement structure. A snap ring on the cannula portion engages a snap ring in the lumen of a sheath hub formed on the proximal end of the splittable sheath. An O-ring between the cannula portion and the sheath hub provides a fluid-tight seal.

摘要： A splittable cannula includes a radiopaque marker placed at or near the distal end of the cannula. The radiopaque marker may be a unitary piece, or may consist of several portions. The cannula may include a sheath or catheter body with a grooved score line running along a portion of the sheath body and a radiopaque marker located at a distal end of the body and abutting the body. The radiopaque marker may be located within the lumen of the sheath, may be embedded in the sheath wall, or may be affixed to the external sheath wall. The radiopaque marker may be scored, notched, grooved, or contain apertures longitudinally. The notches, grooves, apertures, and/or score lines in both the sheath or catheter body and the radiopaque marker serve to provide a weakened tear path. An electrode lead may be coupled with the radiopaque marker.
