Abstract:
A medical instrument may include a tube, a sheath provided around and coaxial with the tube, and an inflatable balloon at a distal end of the sheath. The balloon may receive a fluid from a lumen of the sheath, and may have a central opening along a longitudinal axis thereof, and into which the tube extends, a proximal portion, a middle portion adjacent to and distal of the proximal portion, and a distal portion adjacent to and proximal of the middle portion. When the balloon is inflated with the fluid, a maximum diameter of the middle portion may be less than a maximum diameter of the proximal portion, and less than a maximum diameter of the distal portion. The medical instrument may also include an extraction member provided at a distal end of the tube, distal to the balloon, and movable axially relative to the balloon.
Abstract:
A medical device may include a stimulation member configured to apply a stimulus to a nerve that is configured to control a contraction of an airway distal to the nerve, and a measurement member configured to measure an effect of the stimulus on the airway. The medical device also may include an energy delivery element configured to deliver energy to tissue defining the airway to reduce an effect of the stimulus on the airway. The energy delivery element may be disposed at or distally of the stimulation member.
Abstract:
A method of treating an airway of a lung may include inserting a medical device into the airway, and delivering an agent from the medical device to a nerve disposed within or adjacent the airway to damage the nerve sufficient to reduce an ability of the nerve to send nerve signals.
Abstract:
A method for treating a lung may include forming a channel between a first airway and a second airway through a tissue of the lung to allow air trapped within the first airway to flow through the channel and the second airway, and inserting a support member into the channel.
Abstract:
A method of monitoring a lung condition of a patient may include automatically receiving a diagnostic signal from one or more sensors delivered adjacent to or within a lung of the patient. The one or more sensors may be active to conduct diagnostic monitoring of the lung. The method also may include calculating a diagnostic value based on the diagnostic signal, and determining, based on the diagnostic value, a change in the lung condition.
Abstract:
A medical device may comprise a distal tip having a viewing element, a lighting element, and at least one feature configured to removably couple the distal tip to a shaft. The medical device may also comprise a working channel coupled to the distal tip and defining a central lumen configured to receive a tool. A wall of the working channel may define at least one additional lumen. The working channel may be configured to be removably inserted into the shaft. The medical device may also comprise at least one of a wire, a cable, or a conduit passing through the at least one additional lumen.
Abstract:
A medical device includes a handle including a stationary body, a first movable body, and a second movable body; a control member coupled to the second movable body; an intermediate sheath coupled to the first movable body; an external sheath coupled to the stationary body; and an end effector. The end effector includes a first loop and a second loop. The first loop includes a first arm and a second arm, and the first arm is coupled to the intermediate sheath. The second arm is coupled to the control member, and the second arm includes a first plurality of teeth. The second loop includes a third arm and a fourth arm. The third arm is coupled to the intermediate sheath, and the fourth arm is coupled to the control member. The fourth arm includes a second plurality of teeth.
Abstract:
An apparatus for positioning a device relative to tissue may include an emitter and a detector coupled to the device. The emitter may emit energy onto the tissue. The detector may detect energy reflected from the tissue. The detector may also generate a detector output signal indicative of a characteristic of the reflected energy. The apparatus may also include a processor that receives the detector output signal from the detector. The processor may determine whether there has been relative movement between the device and the tissue based on the detector output signal. The processor may also generate a processor output signal based on the relative movement. The apparatus may also include an actuator assembly engaging the device. The actuator assembly may receive the processor output signal from the processor. The actuator assembly may also move the device based on the processor output signal.
Abstract:
A medical device for regulating fluid flow within one or more lungs of a patient is disclosed. The medical device includes an elongate tubular member, a first extension, a second extension, and a valve member. The elongate tubular member includes a first plurality of channels extending between a proximal and distal ends. The first and second extensions defines a second and third plurality of channels, respectively, each extending from the distal end of the elongate tubular member and configured for placement in a first and second passageway of a lung. The valve member operably couples to the elongate tubular member and is configured to transition between a first position and a second position. The valve member prevents fluid flow to first set of the first plurality of channels in the first position and prevents fluid flow to second set of the first plurality of channels in the second position.
Abstract:
Provided are devices, systems and methods of selectively controlling air flow into one or more section of a patient's lungs. In particular, the devices may be valve devices having an inner lumen configured to transition between a first diameter and a second diameter smaller than the first diameter to control the airflow through the valve.
