Abstract:
An airway sizing apparatus (10) for determining a cross-sectional length (20)of an airway (30) of a subject (40) comprising: a guide rod assembly (50) including one or more control members (52) and a distal scale (54); a collar assembly (70) disposed on the guide rod assembly, configured to radially expand and contract with activation of the one or more control members; wherein the collar assembly includes a collar indicator member (72) that moves linearly on the distal scale to indicate the cross-sectional length of the airway.
Abstract:
The present teachings relate generally to a medical flexible needle assembly (10), comprising a needle portion (20) disposed at a distal end (12) of the assembly; a stiff portion (30) disposed at a proximal end 14 of the assembly; an flexible portion (40) disposed between and interconnecting the needle portion and the stiff portion, including a flex distal portion (42), a flex proximal portion (44); and a jacketing member (50) disposed about the assembly (10) over at least part of the flexible portion (40); characterized in that the jacketing member (50) includes one or more coupled regions (60) and one or more decoupled region (70), wherein in at least one or more of the one or more coupled regions (60) are located proximally, distally, or both of the flexible portion (40).
Abstract:
A medical instrument having an aspiration needle and handle retraction mechanism. The handle device controls the force required for a user to activate the needle and provides a higher force to activate and a counter force to auto-retract the needle.
Abstract:
A valve (2) comprising: (a) membrane (50) and (b) a frame (10) in communication with the membrane so that the frame expands the membrane, the frame including: (i) a rod (4), (ii) a plurality of struts (12) connected to the rod at a distal end and extending generally radially outward as the struts extend away from the distal end and towards a proximal end; (iii) a plurality of anchors (30) that are in direct communication with the struts between the distal end and the proximal end, each of the plurality of anchors extending through an exit location (52) in the membrane.
Abstract:
A device including a catheter (14) and a medical instrument (12). The catheter includes an inner portion (16) and one or more unlocking features (18). The medical instrument includes one or more locking features (24). When the medical instrument is in the inner portion of the catheter, the one or more unlocking features engage the one or more locking features so that the medical instrument can bend in the catheter. When the medical instrument is outside the catheter, the one or more unlocking features disengage from the one or more locking features so that the medical instrument is restricted from bending.
Abstract:
Embodiments of a sizing device that can be used to measure the size of airways lumens, such as those connected to lungs. The sizing device can have different expandable elements in order to accurately and consistently measure the particular dimensions of a lumen. In some embodiments, markings vie wable by a user can be used to determine the particular size.
Abstract:
Devices and methods for measuring size of airways to lung are disclosed. A light- based endoluminal sizing device can comprise a centering tool, a light source, and a marker. A size of an airway can be approximated or determined based on a distance between the marker and the light source when light from the light source intersects the marker at an interface between the marker and the airway wall. In some cases, the size of the airway can be approximated from observing an intersection between a light pattern and the airway waif.
Abstract:
A medical device system includes an introducer tube defining a lumen and an opening at a distal end. A medical device is disposed within the lumen of the introducer tube in a first position. The medical device is movable within the introducer tube between the first position and a second position. In the second position, the medical device extends at least partially beyond the distal end. The medical device defines at least one echogenic feature thereon for allowing visualization of the medical device upon insertion of the medical device in the patient's anatomy. In one form, a surgical electrode for insertion into a patient's anatomy is provided. The surgical electrode, which is configured to apply a current to a tissue, includes a coil defining a plurality of helical turns and at least one echogenic feature for allowing visualization of the coil when the coil is inserted into the patient's anatomy.
Abstract:
A tool for manipulating a foreign body (e.g., a deployed medical device) can include an operative portion. The operative portion can be used to move the foreign body in the proximal and/or distal directions with respect to the removal/repositioning tool and/or the tissue surrounding the foreign body. In some embodiments, the tool can include a compressing portion that can be used to compress the foreign body as the foreign body is pulled by the operative portion in the proximal direction. The tool can further include a sleeve that can be used to transition the operative portion and/or compressing portion between an opened configuration and a closed configuration. In some embodiments, the tool can be used in conjunction with an endoscope to navigate the tool to the site of a foreign body within the body of a patient.
Abstract:
Systems for minimally invasively treating an air leak in a lung (10) comprise a balloon catheter (40) configured for locating an airway in fluid communication with the air leak, a one-way valve occlusion device (140) for occluding inspiratory airflow through the airway in clued communication with the air leak and a bronchoscope (30) and/or a delivery catheter (200) configured to deliver the occlusion device (140) the into a patient's airway in a position adjacent to a target section selected using the balloon catheter 40. The airway occlusion device (140) is preferably removed after the air leak has substantially permanently healed. The system can further include a substance to be injected into the airway on a distal side of the occlusion.
