Embodiment Construction

[0034] The fluid management system of the present invention includes devices for facilitating the removal of fluid from areas of the body that require drainage, such as the peritoneum, pleural cavity, or pericardial sac. The devices disclosed herein can be used to drain chronic excess fluid from one body cavity to a second body cavity, preferably the bladder. Such excess fluid can build up due to underlying conditions such as cancer. According to the principles of the present invention, a fluid management system can be optimized for treating chronic ascites as well as pleural or pericardial effusions in patients with cancer, while allowing non-invasive monitoring of cancerous cells. After the fluid management system moves excess fluid containing cancerous cells from the first body cavity to the bladder and excretes the fluid during urination, the cancerous cells can be analyzed, for example, to assess the progression of cancer treatment or the cancer itself.

Abstract

A system for noninvasively monitoring cancerous cells within bodily fluid accumulated due to ascites, pleural effusion or pericardial effusion is provided including an implantable pump having control circuitry; a charging and communication system configured to periodically charge and communicate with the implantable pump to retrieve performance data; and monitoring and control software, suitable for use with conventional personal computers, for configuring and controlling operation of the implantable pump and charging and communication system. The implantable pump is configured to move fluid containing cancerous cells from a body cavity to the bladder such that the fluid may be excreted during urination, collected and analyzed with an analysis station to assess progress of the cancer or efficacy of a cancer treatment program.

Description

technical field [0001] The present application relates to devices and methods for the non-invasive monitoring of cancerous cells in body fluids. Background technique [0002] Certain cancers can lead to pathological chronic accumulation of fluid in cavities such as the peritoneum, pleura, or pericardial sac. Such cancers may cause chronic ascites, pleural effusion, or pericardial effusion, where chronic fluid accumulation persists and leads to increased morbidity and mortality. [0003] In a pleural effusion, excess fluid accumulates in the pleural cavity caused by an underlying pathology such as lung cancer, breast cancer, melanoma, leukemia, or lymphoma. If left untreated, effusions may interfere with normal lung function, significantly increasing morbidity and mortality. [0004] In pericardial effusion, fluid accumulates in the pericardial sac and can lead to increased intrapericardial pressure and decreased cardiac output. Excess fluid is often attributed to an under...
