A sheath assembly for an endoscope includes an elongate tubular body and a plug. The endoscope has a handle portion and a scope portion extending therefrom to a tip. The body includes first and second wall sections and extends along a longitudinal axis between first and second distal openings. The first wall section extends radially about the longitudinal axis to define a scope lumen. The scope portion is receivable in the scope lumen. The second wall section extends radially about a portion of the first wall section and longitudinally between second distal and proximal end openings. The first and second wall sections define an integral suction lumen in fluid communication with a first source of negative pressure. The plug is mated with the distal end opening for closing the scope lumen and includes at least one suction opening disposed in co-registration with the first distal end opening.

Endoscopic sheath assembly

A sheath assembly for an endoscope includes an elongate tubular body and a plug. The endoscope has a handle portion and a scope portion extending therefrom to a tip. The body includes first () and second () wall sections and extends along a longitudinal axis between first and second distal openings located at distal and proximal ends thereof, respectively. The first wall section () extends radially about the longitudinal axis to define a scope lumen (). The scope portion is receivable in the scope lumen with the distal and proximal ends. The second wall section () extends radially about a portion of the first wall section () and longitudinally between second distal and proximal end openings. The first and second wall sections define an integral suction lumen () in fluid communication with a first source of negative pressure. The plug is mated with the distal end opening and includes a lens surface through which energy is transmissible.

A catheter assembly comprises a first catheter including a wall with an inner surface at least partially defining a lumen. A second catheter is connected to the wall of the first catheter and is disposed outward of the inner surface of the wall. The second catheter is at least partially covered by a sheath portion of the first catheter. A first portion of the wall of the first catheter is made of a relatively low durometer elastomeric material and is relatively extensible. A second portion of the wall is formed of a relatively high durometer elastomeric material and is relatively inextensible.

The present invention provides a system for enabling the sensing of changes in pressure in response to uterine muscle tone changes relating to contractions, and for enabling the evaluation of contractions based thereon. The system enables a portion thereof to effectively and efficiently project at least partially below the non-compressed abdominal surface, and provides electrical isolation of the system elements. It enables ease of use and enhanced patient comfort. It also enables maximized sensitivity and minimized system loading retention pressure.

Uterine contraction sensing system and method

A protective sheath for a pulse oximetry sensor. The sheath covers the sensor and inhibits contamination thereof during use. The sheath obviates the need to clean the pulse oximetry sensor after each use while reducing the likelihood of cross-patient contamination. The sheath allows the use of reusable pulse oximetry sensors and thus significantly reduces the overall costs of such sensors per use.

Methods and apparatus for inhibiting contamination of reusable pulse

A vented fluid collection system including a collection apparatus for use with a device in communication with a mammalian organ or body lumen having a fluid to be sampled therein. The fluid collection apparatus has a blunt cannula having a bore defined therein and a wall defining a small collection chamber in communication with the bore. A fluid sample passes through the bore and is stored in the collection chamber. A vented membrane is disposed at an opening in the wall to allow gas to pass therethrough but prevents fluid collected in the collection chamber from passing therethrough. A shroud surrounds and protects the cannula and a cannula cap may be mounted to the shroud to enclose the cannula. In an alternative design of the fluid collection apparatus, the bore acts as the collection chamber. In all designs, when the fluid collection system communicates with a blood vessel, the patient's systemic blood pressure urges the fluid sample into the bore and, in the first design, further into the collection chamber.
