Abstract

An intrauterine pressure-sensing catheter for detecting pressure changes within the uterus of a patient is disclosed having a tube with a primary lumen extending from a proximal end to a distal end of the elongate tube. A monitor lumen is positioned within the elongate tube between the primary lumen and a wall of the elongate tube and extends from a proximal end of the elongate tube to a distal end of the elongate tube. A pressure-compliant balloon is disposed about an exterior of the elongate tube adjacent a distal end tip. A sleeve is slidably mounted on an exterior of the elongate tube and disposed over the pressure-compliant balloon during insertion of the pressure-sensing catheter within the patient. The distal end tip is configured to prevent movement of the sleeve over the tip and is further configured to provide a zone of protection for the pressure-compliant balloon.

Dependent claims

An intrauterine pressure-sensing catheter for detecting pressure within the uterus of a patient comprising:

an elongate tube comprising a primary lumen extending from a proximal end of the elongate tube to a distal end of the elongate tube;
a monitor lumen positioned within the elongate tube, the monitor lumen extending between the proximal end of the elongate tube and the distal end of the elongate tube;
a pressure-compliant balloon defining an interior chamber in fluid communication with the monitor lumen, the pressure-compliant balloon being disposed about an exterior of the elongate tube, the monitor lumen and the interior chamber of the pressure-compliant balloon in combination defining a fluid column;
a sleeve slidably mounted over the exterior of the elongate tube and positioned over the pressure-compliant balloon during insertion of the pressure-compliant balloon of the pressure-sensing catheter within at least the cervix of the patient;
and
an integral distal end tip formed from material of the elongate tube and located adjacent to the pressure-compliant balloon, the distal end tip comprising an outer diameter that is greater than an outer diameter of the sleeve, a rounded front and a back extending substantially transverse to a longitudinal axis of the elongate tube, wherein the distal end tip is symmetric about an axis of the tip corresponding to a longitudinal axis of the elongate tube, and wherein a diameter of the distal end tip is equal to or greater than a diameter of the pressure-compliant balloon when inflated.

A pressure-sensing catheter for detecting pressure within a cavity of a patient, comprising:

an elongate hollow tube comprising a primary lumen extending between a proximal end of the elongate hollow tube and a distal end of the elongate hollow tube, the elongate hollow tube comprising a polyethylene co-vinyl acetate;
a monitor lumen positioned within the elongate hollow tube, said monitor lumen extending between a proximal end of the elongate hollow tube and a distal end of the elongate hollow tube and in fluid communication with a pressure-compliant balloon on an exterior of the elongate hollow tube;
a sleeve disposed about the exterior of the elongate hollow tube, the sleeve having a linear proximal portion, a linear distal portion and a curvilinear medial portion, the sleeve being slideable about a longitudinal axis of the elongate hollow tube and positioned over the pressure-compliant balloon during insertion of the pressure-compliant balloon of the pressure-sensing catheter within at least the cervix of the patient;
a stiffening member comprising a shape memory alloy disposed within a secondary lumen of the elongate hollow tube and extending between the distal end of the elongate hollow tube and the proximal end of the elongate hollow tube, wherein the stiffening member is biased in a linear configuration;
and
an integral distal end tip located adjacent to the pressure-compliant balloon, the distal end tip comprising a rounded front and a back extending substantially transverse to a longitudinal axis of the elongate hollow tube, wherein the distal end tip is symmetric about an axis of the tip corresponding to a longitudinal axis of the elongate hollow tube, and wherein a diameter of the distal end tip is equal to or greater than a diameter of the pressure-compliant balloon when inflated.
