Abstract
Abstract The invention is a valving device for use in laparoscopic surgery. The device generally has a valve housing having a wall defining a common channel. The channel includes at least first and second apertures extending through the channel wall to allow fluid communication to and from the channel. The invention also includes a laparoscopic probe having a channel created by a wall defining a first open end and a second open end, as well as a valve for trapping debris positioned within the channel first open end.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
146 words
A laparoscopic probe comprising a channel, said channel comprising: (a) a wall defining first and second open ends; (b) a flexible valve for aspirating and entrapping debris drawn into said channel while allowing the passage of fluid out of the channel during irrigation, said valve positioned within said wall first open end, said valve comprising silicone rubber and having a thickness ranging from about 0.015 to 0.05 inches, wherein said valve is patterned to open inwardly allowing the aspiration and entrapment of debris, and valve patterning selected from the group consisting of low diameter holes, slits, and mixtures thereof; (c) a sump in fluid communication with said channel wall second open end, said sump comprising an outer wall defining a containment area, said sump outer wall having a greater diameter than said channel wall; and (d) a port, said port in fluid communication with said sump.
Claim 2
Dependent Claim
146 words
A laparoscopic probe comprising a channel, said channel comprising: (a) a wall defining first and second open ends; (b) a flexible valve for aspirating and entrapping debris drawn into said channel while allowing the passage of fluid out of the channel during irrigation, said valve positioned within said wall first open end, said valve comprising silicone rubber and having a thickness ranging from about 0.015 to 0.05 inches, wherein said valve is patterned to open inwardly allowing the aspiration and entrapment of debris, and valve patterning selected from the group consisting of low diameter holes, slits, and mixtures thereof; (c) a sump in fluid communication with said channel wall second open end, said sump comprising an outer wall defining a containment area, said sump outer wall having a greater diameter than said channel wall; and (d) a port, said port in fluid communication with said sump.
