Visualization apparatus for transseptal access
ActiveUS20070293724A1Easy to identify visuallyDifficult to identifyUltrasonic/sonic/infrasonic diagnosticsSurgerySeptal wallVia device
Visualization apparatus and methods for transseptal access are described herein where intravascular access across a septal wall is facilitated via devices which provide for direct visual viewing of tissue area. Such a system may include a deployment catheter and an attached imaging hood deployable into an expanded configuration. In use, the imaging hood is placed against or adjacent to the tissue to be imaged in a body lumen that is normally filled with an opaque bodily fluid such as blood. A translucent or transparent fluid can be pumped into the imaging hood until the fluid displaces any blood leaving a clear region of tissue to be imaged via an imaging element in the deployment catheter. Any number of therapeutic tools or a guidewire can be passed through the catheter and into the imaging hood for crossing the septal wall and passing the guidewire or instruments therethrough.

Nasal cannula assembly
A nasal cannula assembly designed for contact with the nasalabidial area of a patient's face comprising a nasal cannula, a pair of oxygen supply tubes connected to opposite ends of the nasal cannula and a main oxygen supply line. The nasal cannula is made of a flexible plastic material molded into a light-weight hollow tubular member having a main body portion formed at an acute angle in the center and having a pair of spaced exterior orifices projecting from the body at an angle and curved upwardly and inwardly for directing gas flow into a patient's nostrils. Attachment points for oxygen supply tubes are above center of gravity of the nasal cannula to make it self-righting thus eliminating need for stiff supply tubing to orient cannula. Oxygen supply tubes made from ultra-high molecular weight PVC possess superior flexibility and low compression set so that little tension on the tubing is required to hold cannula in proper position. A main oxygen supply line made from ultra-high molecular weight PVC resists the formation of twisted loops that tend to block oxygen flow.

A weld cap is configured and dimensioned to interact with a resilient element, e.g., a spring, and a structural member, e.g., an end cap, so as to securely position the spring relative to the end cap. The weld cap functions to distance the welding process and associated welding energy from the spring, thereby avoiding and / or minimizing any potentially undesirable annealing effect associated with securing / welding the spring relative to the end cap. A first weld cap interacts with the spring at a first end region thereof, and a second weld cap interacts with the spring at a second end region thereof, thereby effectively securing the spring with respect to opposed end caps at either end of an elongated spinal stabilization device. Alignment grooves or channels may be provided for orienting or aligning the spring with respect to the end caps and weld caps. The end regions of the spring may also include bend regions that facilitate the assembly process and / or further minimize the freedom of movement of the spring relative to the end cap / weld cap combination.
