Appl. No.:

09/571570

Inventors:

Michael A. Valerio - Wrentham MA
Trinh Phung - Attleboro MA
Anthony R. Carlone - Bristol RI
Victor E. Santos - Brockton MA

International Classification:

A61M 100

US Classification:

604317, 604320, 604323, 604327, 604328

Abstract:

Featured is a device for draining fluids and/or gas from body cavities, including at least a pressure control chamber and a collection chamber being fluidly coupled by a one-way valve thereby establishing a waterless seal between the collection chamber, including the patient, and the suction source. The pressure control chamber also includes a waterless suction pressure control regulator that controls and maintains the suction pressure at or about a selected value. Preferably, the regulator includes a spring operated valve. The device also includes a vent path arrangement having an intermediate chamber and at least two passages that are perpendicular to two adjacent surfaces within the intermediate chamber. The two passages and intermediate chamber are arranged so liquid in the collection chamber does not flow and contaminate the upstream portions of the device when the device is resting on its front side or backside. Also featured is an autotransfusion system including a drainage device and a bag assembly attached thereto.

International Classification:

A61B 132

US Classification:

600232

Abstract:

The present invention relates to suture organizing and retaining device for use with surgical retractors and devices for stabilizing a predetermined area of the body during a surgical procedure, more particularly to a suture organizing device that is attachable to surgical retractors or is usable separately in connection with minimally invasive coronary artery bypass grafting surgical procedures and heart valve procedures, and more specifically to a suture organizing device having a plurality of suture slots thereon for the releasable attachment of sutures thereto during a surgical procedure to enable the surgeon to retract tissue from the surgical field and wherein the suture organizing device is oriented to extend laterally of the outer surface of the arms of the surgical retractor or in combination with a base member that may be independently positioned adjacent to the surgical site.

Abstract:

A cooled stabilizer is provided for use in coronary bypass grafting surgical procedures. The cooled stabilizer can be attached to a surgical retractor for providing localized traction, stabilization and/or hemostasis to a predetermined area of body tissue. The stabilizer includes cooling channels and/or pads forming a continuous bottom surface for providing a chilled surface to contact body tissue. In one example, the cooled stabilizer can be shaped as a horseshoe with chilled surfaces over horseshoe sections and optionally over a heel.
