Abstract
Abstract In accordance with the present invention there is provided a device for stabilizing moving tissue, such as a beating heart, so as to facilitate surgical procedures on such tissue. The device includes a tube having a proximal end, a distal end and a lumen extending therebetween. The tube is connected to a suction source so as to draw air through the tube from the distal end to the proximal end. The device further includes at least one foot connected to the distal end of the tube. The foot extends laterally from the tube. In a preferred embodiment the device includes a pair of feet which are spaced apart laterally from each other. Each foot has a proximal surface, and a distal surface for making contact with the tissue. In one preferred embodiment the device includes a filter on said distal surface of each foot whereby particulate material is substantially prevented from entering said lumen of said tube. In another embodiment distal surface of the foot comprises a plurality of pegs extending from the proximal surface.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
136 words
A device for stabilizing moving tissue within the body, said device comprising: a) a tube having a proximal end, a distal end and a lumen extending therebetween, said tube is connected to a suction source so as to draw air through said tube from said distal end to said proximal end; b) at least one foot connected to said distal end of said tube, each said foot extending laterally from said tube, each said foot having a proximal surface, and a distal surface for placement adjacent to said tissue; and c) a plurality of distally extending spaced apart pegs on said distal surface of each said foot, said pegs comprising a filter by forming a tortuous path for any particulate material entering therein whereby particulate material is substantially prevented from entering said lumen for said tube.
Claim 2
Independent Claim
136 words
A device for stabilizing moving tissue within the body, said device comprising: a) a tube having a proximal end, a distal end and a lumen extending therebetween, said tube is connected to a suction source so as to draw air through said tube from said distal end to said proximal end; b) at least one foot connected to said distal end of said tube, each said foot extending laterally from said tube, each said foot having a proximal surface, and a distal surface for placement adjacent to said tissue; and c) a plurality of distally extending spaced apart pegs on said distal surface of each said foot, said pegs comprising a filter by forming a tortuous path for any particulate material entering therein whereby particulate material is substantially prevented from entering said lumen for said tube.
