Method and apparatus for peritoneal oxygenation

Abstract

Embodiments of the invention provide apparatus, systems and method for introducing fluids into a body cavity for treatment. One embodiment provides an apparatus for treating a patient including an access device for insertion into the peritoneal cavity of the patient including an infusion member in a lumen of the access device. An oxygenated solution may be infused and removed into and out of the cavity via the infusion member.

What is claimed is: 
     
         1 . An apparatus configured to treat a patient, the apparatus comprising:
 an access device configured to be inserted a controlled depth into a peritoneal cavity of the patient, the device including a lumen and a tissue penetrating distal end;   an infusion member positioned within a lumen of the access device and advanceable into the peritoneal cavity of the patient, the infusion member including a first lumen and a second lumen for the infusion and removal of an oxygenated solution into and out of the peritoneal cavity;   an oxygen sensor configured to monitor an oxygen partial pressure of the patient or an oxygen saturation of the solution; and   an electronic controller configured to control the infusion and removal of the solution into and out of the peritoneal cavity through the infusion member based on the monitored oxygen partial pressure or the oxygen saturation.   
     
     
         2 . The apparatus of  claim 1 , wherein the first or second lumen is sized to deliver sufficient oxygenated solution to the cavity to at least partially meet the oxygen demands of the patient. 
     
     
         3 . The apparatus of  claim 1 , wherein the oxygen sensor is configured to monitor the oxygen partial pressure of the patient. 
     
     
         4 . The apparatus of  claim 1 , wherein the oxygen sensor is configured to monitor the oxygen saturation of the solution. 
     
     
         5 . The apparatus of  claim 1 , wherein the apparatus includes a CO 2  sensor. 
     
     
         6 . The apparatus of  claim 1 , wherein the access device includes a substantially atraumatic tip. 
     
     
         7 . The apparatus of  claim 1 , wherein the access device includes a sensor configured to determine when the tip of the access device has entered the cavity. 
     
     
         8 . An apparatus configured to treat a patient, the apparatus comprising:
 an access device configured to be inserted a controlled depth into a peritoneal cavity of the patient, the device including a lumen and a tissue penetrating distal end;   an infusion member positioned within a lumen of the access device and advanceable into the peritoneal cavity of the patient, the infusion member including a first lumen and a second lumen for the infusion and removal of an oxygenated solution into and out of the peritoneal cavity;   an oxygen sensor configured to monitor an oxygen partial pressure of the patient or an oxygen saturation of the solution; and   an electronic controller configured to regulate the oxygen saturation of the solution based on the monitored oxygen partial pressure or the oxygen saturation.   
     
     
         9 . The apparatus of  claim 8 , wherein the first or second lumen is sized to deliver sufficient oxygenated solution to the cavity to at least partially meet the oxygen demands of the patient. 
     
     
         10 . The apparatus of  claim 8 , wherein the oxygen sensor is configured to monitor the oxygen partial pressure of the patient. 
     
     
         11 . The apparatus of  claim 8 , wherein the oxygen sensor is configured to monitor the oxygen saturation of the solution. 
     
     
         12 . The apparatus of  claim 8 , wherein the apparatus includes a CO2 sensor. 
     
     
         13 . The apparatus of  claim 8 , wherein the access device includes a substantially atraumatic tip. 
     
     
         14 . The apparatus of  claim 8 , wherein the access device includes a sensor configured to determine when the tip of the access device has entered the cavity. 
     
     
         15 . An apparatus configured to treat a patient, the apparatus comprising:
 an access device configured to be inserted a controlled depth into a peritoneal cavity of the patient, the device including a lumen and a tissue penetrating distal end;   an infusion member positioned within a lumen of the access device and advanceable into the peritoneal cavity of the patient, the infusion member including a first lumen and a second lumen for the infusion and removal of a oxygenated solution into and out of the peritoneal cavity; and   a CO2 sensor in communication with an electronic controller, where the electronic controller is configured to control the infusion and removal of the solution into and out of the peritoneal cavity through the infusion member.   
     
     
         16 . The apparatus of  claim 15 , wherein the first or second lumen is sized to deliver sufficient oxygenated solution to the cavity to at least partially meet the oxygen demands of the patient. 
     
     
         17 . The apparatus of  claim 15 , wherein the oxygen sensor is configured to monitor the oxygen partial pressure of the patient. 
     
     
         18 . The apparatus of  claim 15 , wherein the oxygen sensor is configured to monitor the oxygen saturation of the solution. 
     
     
         19 . The apparatus of  claim 15 , wherein the access device includes a substantially atraumatic tip. 
     
     
         20 . The apparatus of  claim 15 , wherein the access device includes a sensor configured to determine when the tip of the access device has entered the cavity.
