摘要:
The invention relates to methods of differentiation, isolation, propagation, and storage of small colony variants (SCVs) of E. coli, preferably E. coli 83972 or E. coli HU2117, or modified or variant forms thereof, and methods for using the prepared SCV bacteria to establish probiotic biofilms in treated subjects and/or on treated medical devices.

A catheter assembly includes an inner liner made of flexible material and an outer layer having a steering mechanism. A catheter assembly is provided that includes an inner liner made of flexible material, and an outer layer having a steering mechanism that includes at least one wire and a corresponding lumen for each of the at least one wire through which the respective wire may travel. The outer layer includes a braided wire assembly that includes at least two wires braided into a wire mesh, and further includes a see-through portion positioned proximate a pull wire extraction location to facilitate extraction.

A flexible tube 25 for an endoscope 10 includes a helical tube 100, a cover 400, and an inhibition mechanism 500. The inhibition mechanism 500 enables movement of a densely wound portion 103 to the cover 400 in a direction of a central axis of the helical tube 100 and inhibits movement of a loosely wound portion 101 to the cover 400 in the central axis direction of the helical tube 100.
摘要:
Cleaning systems and devices are provided for cleaning body-inserted tubes (e.g., endotracheal tubes, chest cleaning tubes). In one embodiment, a closed suction system comprises a suction catheter having at least one deployable (e.g., inflatable) cleaning member at a distal portion of the suction catheter and at least one suction opening distal to the cleaning member. The closed suction system module may comprise a control unit at its proximal end adapted to facilitate operation in one of the following three operational states: i) a first operational state in which only the cleaning member is functional, ii) a second operational state in which only suction is functional, or iii) a third operational state in which neither suction nor the cleaning member is functional.
摘要:
A catheter has extruded length of tubing and an injection molded tip that facilitates insertion of the catheter into the body. The catheter is fabricated by the steps of providing the tubing, for example, by extruding the tubing from a thermoplastic resin cutting the tubing to the desired length, inserting a plug into the tubing, inserting one end of the tubing into an injection mold cavity, creating and forming a tip in an injection molding step, and demolding the tubing with the formed tip.

A stent indwelling device includes a guide catheter and a pusher catheter. The guide catheter includes: a core section; an outer layer section surrounding an outer circumference of the core section; a stent protection section disposed between the core section and the outer layer section, being longer than a dimension of a tube stent, having stiffness resisting compression inward in a radial direction perpendicular to a longitudinal axis of the guide catheter, and having flexibility in a direction in which the guide catheter is curved; and a stopper configured to allow expansion of the stent protection section in a direction along the longitudinal axis and restrict movement of the stent protection section in the direction with respect to the core section.
摘要:
An intravascular catheter is disclosed that includes an elongated shaft defined by a wall including at least one port extending through the wall into a lumen. At least one channel may be defined between layers of polymer making up the catheter shaft. The channel extends along at least a portion of the shaft and is in fluid communication with the port. Outer and inner diameters of the catheter may be substantially constant along the length of the catheter.
