Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
61 words
An esophageal probe, comprising: an elongated hollow sleeve; first electrical means for detecting sounds at a first distal location in the sleeve, and a conductive lead connected to the first detecting means; and second electrical means for separately detecting sounds at a second location in the sleeve proximal said first location, and a conductive lead connected to the second detecting means.
Claim 2
Dependent Claim
61 words
An esophageal probe, comprising: an elongated hollow sleeve; first electrical means for detecting sounds at a first distal location in the sleeve, and a conductive lead connected to the first detecting means; and second electrical means for separately detecting sounds at a second location in the sleeve proximal said first location, and a conductive lead connected to the second detecting means.
Claim 3
Dependent Claim
79 words
An esophageal probe, comprising: an elongated hollow sleeve defining a cavity, and having a distal end, and a proximal end; first electrical sound detection means at a first distal location in the sleeve cavity, and a conductive lead connected to the first detection means; and second electrical sound detection means in the sleeve cavity, said second detection means being spaced a substantial distance proximally from the first detection means, and a conductive lead connected to the second detection means.
Claim 4
Dependent Claim
79 words
An esophageal probe, comprising: an elongated hollow sleeve defining a cavity, and having a distal end, and a proximal end; first electrical sound detection means at a first distal location in the sleeve cavity, and a conductive lead connected to the first detection means; and second electrical sound detection means in the sleeve cavity, said second detection means being spaced a substantial distance proximally from the first detection means, and a conductive lead connected to the second detection means.
Claim 5
Dependent Claim
15 words
The probe of claim 2 wherein said first and second sound detection means comprise microphones.
Claim 6
Dependent Claim
19 words
The probe of claim 3 wherein the first detection means is located adjacent a distal end of the sleeve.
Claim 7
Dependent Claim
27 words
The probe of claim 3 wherein the first detection means is located in the proximity of a patient's heart when the probe is inserted into the patient.
Claim 8
Dependent Claim
85 words
An esophageal probe, comprising: a disposable housing having an elongated sleeve defining a cavity; a permanent monitoring device having an elongated stem receivable in the sleeve cavity, said monitoring device having first electrical sound detection means at a first distal location of the stem, and second electrical sound detection means at a second location of the stem positioned a substantial distance proximally from the first location; and means for releasably attaching the monitoring device to the housing with said stem received in the sleeve cavity.
Claim 9
Dependent Claim
85 words
An esophageal probe, comprising: a disposable housing having an elongated sleeve defining a cavity; a permanent monitoring device having an elongated stem receivable in the sleeve cavity, said monitoring device having first electrical sound detection means at a first distal location of the stem, and second electrical sound detection means at a second location of the stem positioned a substantial distance proximally from the first location; and means for releasably attaching the monitoring device to the housing with said stem received in the sleeve cavity.
Claim 10
Dependent Claim
14 words
The probe of claim 6 wherein the first and second detection means comprise microphones.
