Abstract
Disclosed is an ambulatory system for monitoring one or more physiological parameters in a body lumen, such as the esophagus. The system includes an implantable probe having a sensor for the physiological parameter and a transmitter for transmitting data to an external receiver. The probe may be used for monitoring any of various physiological parameters, including pH, temperature, and pressure, within the esophagus or other body lumens. Methods and deployment catheters are also disclosed.
Claims26
A method of attaching a device to a tissue surface inside of a patient, comprising the steps of:
- providing a device having a housing, a concavity on the housing, a window to permit visualization through the housing of the interior of the concavity, and a pin that is axially movable from a retracted position within the housing to an extended position that extends at least part way across the concavity;
- carrying the device on an introduction instrument into the body;
- positioning the device at an attachment site in the body such that the concavity is adjacent the tissue surface at the attachment site;
- drawing tissue into the concavity;
- advancing the pin through the tissue to retain the device at the attachment site, and
- withdrawing the introduction instrument from the body leaving the pin at the attachment site.
A method of attaching a device to a tissue surface inside of a patient, comprising the steps of:
- providing a device having a housing, a concavity on the housing, and a pin that is axially movable from a retracted position within the housing to an extended position that extends at least part way across the concavity;
- carrying the device on an introduction instrument into the body;
- positioning the device at an attachment site in the body such that the concavity is adjacent the tissue surface at the attachment site;
- drawing tissue into the concavity;
- advancing the pin through the tissue to retain the device at the attachment site;
- and
- withdrawing the introduction instrument from the body, leaving the pin at the attachment site.
A method of remotely monitoring a physiological parameter in a body lumen of a patient, comprising the steps of:
- providing a device having a housing, a physiological parameter detector in the housing, a concavity on the housing, and a pin that is axially movable from a retracted position within the housing to an extended position that extends at least part way across the concavity;
- carrying the device on an introduction instrument into the body;
- positioning the device at an attachment site in the body such that the concavity is adjacent the tissue surface at the attachment site;
- drawing tissue into the concavity;
- advancing the pin through the tissue to retain the device at the attachment site;
- sensing at least one physiological parameter;
- and
- withdrawing the introduction instrument from the body, leaving the pin at the attachment site.
A method of attaching a device to a surface of an esophagus, comprising:
- providing a device having a housing, a concavity on the housing, and a securing structure that is axially movable from a retracted position within the housing to an extended position which extends at least part way across the concavity;
- carrying the device on an introduction instrument into the body;
- positioning the device at an attachment site in the esophagus such that the concavity is adjacent the surface at the attachment site;
- drawing tissue into the concavity;
- advancing the securing structure into the submucosa of the esophagus, without penetrating the muscular wall of the esophagus, to retain the device at the attachment site;
- and
- withdrawing the introduction instrument from the body, leaving the securing structure at the attachment site.
