A reversible airway device can include a tubular guide, a laryngeal mask, and an endotracheal tube. The tubular guide can have a distal end portion, a proximal end portion, and a first passageway extending between the distal and proximal end portions. The tubular guide can further include a first longitudinal seam. The laryngeal mask can be attached to the distal end portion of the tubular guide. The laryngeal mask can include an opening in fluid communication with the first passageway. The laryngeal mask can further include a second longitudinal seam. The endotracheal tube can be slidably disposed within the first passageway and have a second passageway. The first and second longitudinal seams can be adapted to permit ingress and egress of the tubular guide from the airway without detaching the endotracheal tube from a ventilation source.

Reversible airway device and related method for ventilating a subject

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

Therapeutic apheresis system

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.
