A dialyzer composed of: first and second dialyzation chambers, and an intermediate chamber interposed between the first and second dialyzation chambers. Each of the chambers has a respective one of a blood inlet or outlet and a dialysate inlet or outlet arranged so that blood and dialysate flow in counter-current to one another in both chambers. The intermediate chamber is connected to form a dialysate-free blood flow passage between the blood chambers and is configured to maintain a substantially uniform blood flow.

An annuloplasty ring for repairing a cardiac valve includes an expandable support member having oppositely disposed proximal and distal end portions and a main body portion between the end portions. The proximal end portion of the support member includes a plurality of wing members that extend from the main body portion. Each of the wing members includes at least one hook member for embedding into a cardiac wall and the valve annulus to secure the annuloplasty ring in the valve annulus. The annuloplasty ring may be expanded into full contact engagement with the annulus of the cardiac valve by an inflatable balloon. Methods for repairing a cardiac valve using the annuloplasty ring are also provided.

A medical device suitable for introducing a medical instrument into a patient includes an outer cannula and at least one arm connected to the cannula toward a proximal portion of the at least one arm. The at least one arm is deployable between a closed position and an open position. An inner member is telescopically received in the outer cannula to hold each arm in the closed position. The inner member is deployable to disengage from the arm after the device is inserted into a patient, thereby freeing the arm to be deployed to the open position where it helps hold the outer cannula in the patient. The inner member includes an inner cannula and/or a trocar.

Securable cannula and method

Paired vascular clamps simplify laparoscopic vascular reconstruction surgery by providing an instrument for bringing vessel ends together to a reasonable working distance under a controlled fashion. A first clamp, with a pivoted connecting arm, and a second clamp with a lock/release device for attaching the second clamp to the connecting arm, can be inserted through an trocar or other port into a surgical field and then positioned on with the first clam and the second clamp in side-by-side and substantially parallel relationship, so that said first clamp and said second clamp can hold and position one or more vessels or elongated tissues. A laparoscopic approximator-everter has extendable blades for gripping blood vessel edges or other tissue to be anamosted, and an extendable sheath that can be advanced to surround the blades. Notches in the end of the sheath automatically evert and approximate the blood vessel edges for laparoscopic clip application or suturing when the sheath is advanced to surround the blades.

Surgical instruments and procedures

The present invention relates to an apparatus for monitoring blood parameters during cardio-pulmonary bypass surgery or during other procedures which utilize an extracorporeal circuit. The apparatus is typically used to monitor the percentage of hemoglobin bound with oxygen (oxygen saturation), the total amount of hemoglobin in the blood, and the percent of blood which is comprised of red blood cells (hematocrit), although the apparatus can be adapted to measure other blood parameters. The apparatus (or monitor) provides real-time results to show immediate changes (trending) in the monitored parameters.

Apparatus and method to determine blood parameters

A heat exchanger for medical applications is disclosed. The heat exchanger is characterized in that it is configured to provide a high heat transfer efficiency while minimizing the possibility of formation gaseous emboli and maximizing the ability to entrap and remove any such emboli which form or are introduced into the device. The heat exchanger is particularly well-suited for use in connection with cardioplegia apparatus.
