6398752, Jun 4, 2002

Filed:

Jun 5, 1998

Appl. No.:

09/092374

Inventors:

Ronald Coleman - Oakland CA 94605

International Classification:

A61M 3700

US Classification:

604 614, 604 401, 128898

Abstract:

An extracorporeal support system including an extracorporeal support apparatus and an arterial circulation support catheter. The arterial circulation support catheter includes a blood lumen with a proximal end coupled to extracoporeal support apparatus and a distal end inserted into the blood circulation. A vent lumen has a distal end that crosses the aortic valve into the left ventricle and provides direct venting of the left ventricle through the vent lumen. An arterial circulation support catheter occluding member is positioned either in an interior or at an exterior of the arterial circulation support catheter. A venous circulation support catheter is provided and includes a blood lumen with a proximal end coupled to the extracorporeal support apparatus and a distal end inserted into the blood circulation. A venous circulation support catheter occluding member is included and positioned in an interior or at an exterior of the venous circulation support catheter. The venous circulation support catheter occluding member occludes the superior vena cava and the inferior vena cave.

International Classification:

B62J 300

US Classification:

2802884, 116 56, 280 114, 3403845, 340432, 446404

Abstract:

An accessory which produces distinct sounds in order to alert others of the presence of a bicycle. The accessory is formed of a housing, sound producing assemblies, and a mounting system. The mounting assembly may be clamped around left or right members of bicycle forks, frame, stays, or braces. Housing of the accessory will accommodate mechanical or electronic sound producing elements which are interchangeable and may be used individually or in combination. When installed and the bicycle is in motion, a variety of sounds may be produced depending on the configuration of the sound producing components.

International Classification:

A61M 3700

US Classification:

604 8, 604 9601, 60410101, 60410105, 604919

Abstract:

A medical device assembly is adapted to isolate the heart from systemic circulation while perfusing oxygenated blood to the systemic arterial circulation during a minimally invasive bypasss procedure. An arterial catheter with an external shunt valve forms a funnel which shunts antegrade aortic blood flow from the aortic root, into a distal flow port and through an internal flow lumen in the catheter, out an intermediate flow port along the catheter proximally of the anchor, and into the systemic arterial circulation. A distal internal valve selectively occludes the shunted antegrade aortic blood flow between the distal flow port and the intermediate flow port and isolates the left heart chambers from the systemic arterial circulation. Oxygenated blood may then flow from a cardiopulmonary bypass pump, distally through the internal flow lumen, out the intermediate port. The assembly also includes a venous catheter which aspirates venous blood from the vena cavae and into the cardiopulmonary bypass pump while substantially isolating the right heart chambers from the vena cavae and without circumferentially engaging the internal walls of the vena cavae.

Inventors:

Ronald Coleman - Oakland CA, US

International Classification:

A63H017/40

US Classification:

446/441000

Abstract:

An accessory which produces distinct sounds, in order ro alert others of the presence of a bicycle. The accesssory is forme of a bicycle mounting assembly and a flapper mounting assembly. The bicycle mounting assembly clamps around a member near either the front or rear tire of a bicycle. The flapper mounting assenmbly interchangeably attaches a flapper to the bicycle mounting assembly. When fully installed, the flapper is disposed within the spokes of the bicycle tire. Therefore, when the bicycle is in motion, the spokes impact the flapper producing a sound. Depending on the configuration and size of the flapper, different sounds and sound intensities are produced.

US Classification:

Abstract:

A medical device assembly is adapted to isolate the heart from systemic circulation while perfusing oxygenated blood to the systemic arterial circulation during a minimally invasive bypass procedure. The assembly includes an arterial catheter with an external shunt valve which forms an anchor to secure the distal end portion within the aortic arch and which also forms a funnel which shunts antegrade aortic blood flow from the aortic root, into a distal flow port and through an internal flow lumen in the catheter, out an intermediate flow port along the catheter proximally of the anchor, and into the systemic arterial circulation. A distal internal valve is further provided within the internal flow lumen between the distal and intermediate flow ports. The distal internal valve selectively occludes the shunted antegrade aortic blood flow between the distal flow port and the intermediate flow port and isolates the left heart chambers from the systemic arterial circulation. Oxygenated blood may then flow from a cardiopulmonary bypass pump, distally through the internal flow lumen, out the intermediate port.
