The introducer sheath (10) has a tubular body (11) made of flexible material with a distal portion (12), a proximal portion (13) and an inner surface, the proximal portion (13) being configured to be inserted into a patient's vessel to allow a medical device (100) to be inserted through the introducer sheath (10) into the patient's vessel. The tubular body (11) of the introducer sheath has a wall thickness (d) of 0.3 mm or less. The dilator (20) has a body (21) with a proximal portion (23), a distal portion (22) and an outer surface, the dilator (20) being insertable into the introducer sheath (10) such that its proximal portion (23) extends proximally of the introducer sheath (10) when the dilator (20) is inserted in the introducer sheath (10). At least one of the dilator (20) and the introducer sheath (10) comprises a stiffening structure (25) imparting stiffness to the tubular body (11) of the introducer sheath (10), wherein said stiffening structure (25) can be released, removed or otherwise deactivated.

Abstract: A tray (100) for accommodating a coiled medical device, such as a catheter assembly (700), includes a first compartment (101), a second compartment (102), and a third compartment (103). The catheter assembly (700) and devices associated with a catheterization procedure, such as syringes (701,702) containing sterile water and lubricating jelly and a specimen container (703) can be disposed within the tray. Printed instructions (1001) can be included with the tray (100). One or more layers of wrap material (2200) can be folded about the tray (100) to enclose the tray (100) and other items, such as an additional layer of wrap material (2701), packaged liquid hand sanitizer (2401), and packaged gloves (2402). When a health care services provider (3101) unfolds the wrap material, the same can be used to create a sterile field beneath a patient (3201).

The two non-transverse sensitive grids are connected to each other by a connection and share a common ground lead and a common ground interface. One end of the ground lead is connected to the connection at the middle thereof. The other end of the ground lead is connected to the ground interface. The two non-transverse sensitive grids have equal resistances and are connected to ends of two respective non-ground leads having equal resistances.

Abstract: A catheter is disclosed, which includes an inner tube, and a coil tube disposed on an outer peripheral side of the inner tube, the inner tube being a coil obtained by winding a wire. In addition, in the coil tube, a first coil and a second coil are arranged concentrically with each other. The first coil and the second coil have mutually different winding directions of the wire. Then, the inner tube and the coil tube are rotatable relative to each other around a central axis of the coil tube. In addition, in a natural state where no external force is applied to the catheter, a gap is formed between the inner tube and the coil tube.

Abstract: A fiber optic force sensing assembly for detecting forces imparted at a distal end of a catheter assembly. The structural member may include segments adjacent each other in a serial arrangement, with gaps located between adjacent segments that are bridged by flexures. Fiber optics are coupled to the structural member. In one embodiment, each fiber optic has a distal end disposed adjacent one of the gaps and oriented for emission of light onto and for collection of light reflected from a segment adjacent the gap. The optical fibers cooperate with the deformable structure to provide a change in the intensity of the reflected light, or alternatively to provide a variable gap interferometer for sensing deformation of the structural member. In another embodiment, the gaps are bridged by fiber Bragg gratings that reflect light back through the fiber optic at central wavelengths that vary with the strain imposed on the grating.
