Disclosed is an adjustable occlusion device for use in a body lumen such as the left atrial appendage. The occlusion device is removably carried by a deployment catheter. The device may be enlarged or reduced to facilitate optimal placement or removal. Methods are also disclosed.

Disclosed is an apparatus for facilitating access to the left atrium, and specifically the left atrial appendage. The apparatus may comprise a sheath with first and second curved sections that facilitate location of the fossa ovalis and left atrial appendage. The apparatus may further comprise tissue piercing and dilating structures. Methods are also disclosed.

Apparatus and a method for monitoring a percentage of the oxygen saturation in the hemoglobin of blood flowing through a blood vessel. An optical sensor that detects the percentage oxygen saturation in blood is disposed proximate a proximal end of the catheter. A thermistor is disposed adjacent to the distal end of the catheter and it is employed to detect changes in blood temperature that indicate the position of the catheter's distal end in the blood vessel. Indicia or marks visible at intervals on the outer surface of the catheter enable a medical practitioner to determine the length of the catheter that has been introduced into the blood vessel. A strain relief that is flexible and resists stretching extends along the length of the catheter. For flushing the distal end of the catheter, a fluid supply may be connected to a lumen running through the catheter to provide the flushing fluid. A removable guide wire is inserted in the lumen when positioning the distal end of the catheter at a location in the blood vessel and provides enhanced rigidity for this purpose. The catheter may be coated with an anticoagulant such as heparin, to prevent blood from coagulating on the exterior surface of the catheter.

Intravascular oximetry catheter

A low-profile, self-expanding vascular stent which is preferably cut from a thin tubing. The stent includes helical windings in a single helix, which are joined by bridges for longitudinal and radial strengthening.

A preformed one-piece plastic dispensing tray includes a storage compartment for retaining an elongated, flexible pacing lead therein. A series of spaced apart dividers extend upward from the storage compartment to engage successive serpentine loops of the pacing lead retained in the storage compartment. The construction of the storage compartment permits the pacing lead to be withdrawn therefrom with negligible resistance, and with no twisting, binding, or interference as the lead is inserted into a patient.

A calibrating device for an optical catheter is provided in order to calibrate the catheter for use in a catheter oximeter system. The calibrating device includes a tube having a reference block therein which is spring-loaded into compliant engagement with the distal end of the catheter carrying the fiberoptic light transmitting and receiving guides. A releasable strap tightly secures the catheter to the calibrating device. The packaged catheter is therefore ready for calibration by simply removing the proximal end thereof from a sealed package while the calibrating device and major length of the catheter remain in their sealed and sterilized condition and connecting it to a processor for performing the calibration operation.
