Bed safety rails with added structures for added functionality are shown and described. The added structures may provide additional functionality, aside from safety and security, of electrical power access, a shelf, a cup-holder, a writing-implement-holder, a light-source, a dry erase board, and/or a magnet board for a given bed safety rail. A given bed safety rail may include at least one vertical-safety-rail-member and at least one horizontal-anchor-member that is attached to the vertical-safety-rail-member. The at least one vertical-safety-rail-member may provide the safety and security features; as well as the additional functional features. The at least one horizontal-anchor-member may have structure permitting the given bed safety rail to be removably anchored to a given bed.

Bed safety rail

Flexible frameworks are described including a plurality of at least one structural component having a waveform axially stacked and configured to form at least one internal conduit.

Flexible structures

A guide catheter includes an outer guide having an open lumen and a longitudinal pre-stress line extending between a distal end and a proximal end of the outer guide. The outer guide has a longitudinal stiffness that facilitates transmission of forces and prevention of kinking during steering of the outer guide within cardiac vasculature and structures. An inner guide has an open lumen and is movably displaceable within the open lumen of the outer guide. At least a distal end of the outer guide and inner guide are dimensioned for passage into the patient's coronary sinus. A guide handle is connected to the proximal end of the outer guide and includes a longitudinal pre-stress line separable into at least two sections such that guide handle separation splits the outer guide along the longitudinal pre-stress line at the proximal end of the outer guide.

Telescoping guide catheter with peel-away outer sheath

A guide catheter employs a retractable inner sheath movably disposed within an open lumen of an outer sheath. The inner sheath includes a pre-formed distal end and an open lumen adapted to receive a payload. The inner sheath is translatable and rotatable relative to the outer sheath. The inner sheath conforms to the outer sheath shape until it is distally extended beyond the outer sheath. The outer sheath contains a steering tendon that can be used to adjustably deflect the outer sheath. The guide catheter further includes a proximally attached guide handle. A steering handle can be pivotably connected to the guide handle. The steering handle is connected to the steering tendon and can apply a tensile force to the steering tendon for adjustably deflecting the outer sheath. A catheter according to the present invention provides an improved system for locating and cannulating cardiac venous structures, particularly the coronary sinus via the right atrium.

Steerable guide catheter with pre-shaped rotatable shaft

Methods of using a guide catheter employ a retractable inner guide movably disposed within an open lumen of a splittable outer guide. The outer guide includes a longitudinal pre-stress line extending from distal to proximal ends. The inner guide includes an open lumen adapted to receive a payload. The inner guide is translatable and rotatable relative to the outer guide. The guide catheter further includes a proximally attached guide handle which is separable into at least two sections. Separation of the guide handle splits the proximal end of the outer guide. Proximal outer guide retraction continues the splitting of the outer guide along the longitudinal pre-stress line.

An intracorporeal catheter such as a guiding catheter employed for intravascular procedures which generally has an elongated catheter shaft with a polymeric wall with a multistrand reinforcing structure wherein the strands at a plurality of cross point locations of the reinforcing structure are secured together to hold at least part of the braided reinforcing structure in a desired shape for utilization. The strands may be metallic or polymeric or mixtures thereof. The strands can be secured together at the cross points thereof by a variety of ways. In one embodiment a plurality of the strands forming the reinforcing structure are formed of metal and are provided with a coating of solder so that the strands can be secured together by applying heat to the strands at the cross point locations to melt the solder and allow a solidified solder connection between the strands to be formed upon cooling while holding at least the portion of the reinforcing structure having secured cross points while holding the portion of the reinforcing structure in the desire shape. Other embodiment involve other methods of securing the strands at the cross points including welding, brazing, adhesives or mechanical connections.
