Esophageal stethoscope with separate cover member
First Claim
1. An esophageal stethoscope assembly, comprising:
- a tubular flexible body having a proximal end and a distal end, and including an acoustic input region defined on the tubular flexible body toward the distal end;
a carrier member separate from the tubular flexible body and engageable with the tubular flexible body, wherein the carrier member includes one or more devices for sensing and/or controlling a condition from or within the esophagus of a patient, wherein the tubular flexible body extends along a longitudinal axis, and wherein the carrier member defines an axial passage and includes wall structure defining a pair of spaced ends, wherein the space between the spaced ends of the wall structure is in communication with the axial passage, and wherein the carrier member is engageable with the tubular flexible body by application of a push-on force transverse to the longitudinal axis of the tubular flexible body such that the tubular flexible body passes through the space between the wall structure ends and into the axial passage of the carrier member, wherein the carrier member wall structure is formed of a resilient material such that the wall structure is separable to enlarge the space between the wall structure ends to allow the tubular flexible body to pass therethrough into the axial passage of the carrier member, and wherein the resiliency of the wall structure is operable to thereafter engage the wall structure with the tubular flexible body; and
a retainer structure interposed between the carrier member and the tubular flexible body for maintaining the carrier member in a predetermined axial position relative to the tubular flexible body.

Abstract
An esophageal stethoscope includes a tubular flexible body having an acoustic input region. A carrier member, which is separate from the tubular flexible body, is selectively engageable with the tubular flexible body either proximally or distally of the acoustic input region. The carrier member carries one or more devices for providing esophageal recording, monitoring or stimulation functions. For transesophageal cardiac pacing, electrodes are mounted to the carrier member such that engagement of the carrier member with the tubular flexible body functions to convert the esophageal stethoscope to a pacing stethoscope. To carry out a sensing, recording or monitoring function, such as esophageal oximetry, one or more oximetry probes are mounted to the carrier member such that engagement of the carrier member with the esophageal stethoscope converts the stethoscope for use in an oximetry sensing application. A “universal” stethoscope includes engagement structures at predetermined locations along the length of the tubular flexible body, for use in engaging a stimulation carrier and/or a recording/monitoring carrier with the esophageal stethoscope.

5. An esophageal stethoscope assembly, comprising:
-
a tubular flexible body having a proximal end and a distal end, wherein the tubular flexible body defines a length and includes an acoustic input region located toward the distal end;
a carrier member separate from the tubular flexible body and engageable with the tubular flexible body, wherein the carrier member has a length less than that of the tubular flexible body and includes one or more devices for sensing and/or controlling a condition from or within the esophagus of a patient; and
one or more electrical lead wires, wherein the one or more devices are interconnected with the one or more electrical lead wires, wherein the carrier member has a proximal end and defines passage structure for receiving the one or more electrical lead wires and wherein the passage structure is oriented such that the one or more electrical lead wires extend from a proximal end defined by the carrier member, and wherein the electrical lead wires are located exteriorly of the tubular flexible body and are exposed between the carrier member and the proximal end of the tubular flexible body. - View Dependent Claims (6)
