摘要： Apparatus and methods are provided for creating tubular devices, e.g., as components for catheters, sheaths, and or other devices sized for introduction into a patient. In one embodiment, a method is provided for making a tubular device using a sheet of material including a coated first surface. The sheet is rolled around a mandrel until longitudinal edges of the sheet are disposed near or adjacent one another, e.g., without attaching the longitudinal edges together. A tubular braid is positioned over the sheet-wrapped mandrel, one or more tubular segments are positioned over the tubular braid, and heat shrink tubing is positioned over the tubular segments. The resulting assembly is heated to cause the tubular segments to at least partially reflow and/or otherwise laminate the tubular segments to the tubular braid and sheet. The heat shrink tubing and mandrel are then removed to create the tubular device.

摘要： Systems and methods are provided for injecting one or more agents into tissue within a patient's body. In one embodiment, an injection device includes a substantially axially incompressible elongate member including a lumen extending between proximal and distal ends thereof. A distal stop is provided on the distal end and a needle tip extends distally beyond the distal stop, the needle tip having a cross-section smaller than the distal end. The needle tip includes a passage communicating between the lumen and an outlet in the distal tip that has having a cross-section smaller than the lumen. In an exemplary embodiment, the elongate member includes a coil extending between the proximal and distal ends, and a sleeve disposed within an interior region of the coil extending between the proximal and distal ends. The sleeve defines the lumen and may be free-floating within at least a portion of the coil.

摘要： Tubular devices are provided that include a proximal end, a distal end sized for introduction into a patient's body, a central lumen, a conductor extending between the proximal and distal ends adjacent the central lumen, reinforcement members including windings extending helically around the central lumen, and an outer jacket. The tubular device includes a first portion in which the conductor extends helically around the central lumen, and a second portion in which the conductor extends longitudinally and either a) all of the windings surround the central lumen and the conductor remains outside the windings, b) at least some of the windings pass between the central lumen and the conductor and at least some of the windings surround both the central lumen and the conductor, and c) all of the windings surround both the central lumen and the conductor. Methods for making such tubular devices are also provided.

摘要： Systems and methods are provided for injecting one or more agents into tissue within a patient's body that includes a catheter. A needle guide extends from a distal end of the catheter and terminates at a distal tip, e.g., including a foot with an atraumatic contact surface, the needle guide having a cross-section smaller than the distal end and being biased to a curved shape. The needle guide includes a passage communicating from a lumen of the catheter to an outlet at the distal tip, and a needle device is disposed within the passage that may be deployed from the outlet to inject one or more agents into tissue. The catheter also includes an imaging assembly on the distal end configured to acquire images of tissue adjacent the needle guide distal tip.

摘要： Telescoping catheters are provided that include an outer tubular member and an inner member slidably received within a lumen of the outer member. The outer and inner members include cooperating magnetic elements on their distal ends. The magnetic elements may be mounted at locations to secure the inner member at a first axial position, e.g., a retracted position, using a magnetic attraction between the magnetic elements. The inner member may be moved axially from the first position by overcoming the magnetic attraction such that a predetermined axial force may disengage the magnetic elements to allow the first elongate member to directed from the first position to one or more other axial positions.

摘要： Deflectable apparatus and methods for performing a procedure within a patient's body using such apparatus are provided. Generally, the apparatus includes an elongate tubular member including a proximal end, a distal end, a longitudinal axis extending between the proximal and distal ends, a deflectable distal portion including first and second lumens spaced apart from one another on generally opposite sides of the longitudinal axis, and a handle coupled to the proximal end of the tubular member. A pull wire includes a loop disposed within the handle and first and second segments extending from the loop and slidably received in the first and second lumens, respectively, and coupled to the distal end. An actuator is provided on the handle for applying tension to either the first or the second segment to cause a distal portion of the tubular member to deflect, e.g., in opposite directions.
