A catheter may include an elongate body extending from a proximal end to a distal end and defining a lumen; a push member mechanically coupled to the proximal end of the elongate body; and a slidable push grip disposed about an outer perimeter of the push member. The slidable push grip is controllably engageable with the push member. When the slidable push grip is in an engaged state with the push member, the slidable push grip transmits an axial force to the push member to enable the push member to transmit the axial force to the elongate body. When the slidable push grip is in a disengaged state with the push member, the slidable push grip is movable axially in at least one direction along a length of the push member while transmitting substantially no axial force to the push member.

A delivery cable for delivering a medical device and a delivery device including the same are described herein. The delivery cable includes a flexible inner core, an outer coil surrounding at least a portion of the flexible inner core, and a pull wire disposed between the flexible inner core and the outer coil, the pull wire configured to deflect a distal deflectable portion of the delivery cable upon manipulation thereof. Methods of making the delivery cable and methods of using the delivery cable to deploy a medical device are also described herein.

A method and system of correcting alignment of catheter relative to a target including receiving signals from an inertial measurement unit located at a distal end of a catheter, determining movement of the distal end of the catheter caused by physiological forces, receiving images depicting the distal end of the catheter and the target, identifying the distal end of the catheter and the target in the images, determining an orientation of the distal end of the catheter relative to the target and articulating the distal tip of the catheter in response to the detected movement to achieve and maintain an orientation towards the target such that a tool extended from an opening at the distal end of the catheter would intersect the target.

A catheter system may include a catheter assembly and a catheter delivery device. The catheter assembly may include a catheter adapter, which may include a catheter adapter distal end, a catheter adapter proximal end, and a catheter adapter lumen extending through the catheter adapter distal end and the catheter adapter proximal end. The catheter assembly may include a primary catheter extending from the catheter adapter distal end. The catheter delivery device may include a housing, which may include a housing distal end coupled to the catheter assembly, a housing proximal end, and a housing lumen extending through the housing distal end and the housing proximal end. A secondary catheter may be disposed within the housing. The secondary catheter may be configured to move distally through the catheter assembly in response to a fluid pressure provided by a fluid delivery device coupled to the housing proximal end.

Catheter and catheter assemblies for extracorporeal circulation of body fluids, such as blood, are described. A catheter includes a septum that divides an internal lumen into fluidicly isolated drainage and infusion lumens. The infusion lumen extends along only a portion of the axial length of the catheter and terminates at an infusion opening defined by the circumferential wall of the elongate member of the catheter. The drainage lumen extends the full axial length of the catheter and is laterally accessible via first and second sets of drainage openings.

An embodiment of the disclosure is a catheter system configured to be attached to an implanted medical device, such as an implanted valve. The catheter includes an engagement assembly having an elongated member that extends along a central axis, and an engagement member coupled to the elongated member. The engagement assembly has a retracted configuration, where the engagement member is disposed within the channel of the catheter, and an engagement configuration, where the engagement member is disposed outside of the channel and extends outwardly along a direction that is angled with respect to the central axis.

A catheter system (100) for treating a treatment site (106) within or adjacent to a vessel wall (108A) or a heart valve includes a light source (124), a first light guide (122A), a second light guide (122A), and an optical alignment system (257). The light source (124) generates light energy (224A, 224B, 324A, 324B, 424B). The first light guide (122A) receives the light energy (224A, 224B, 324A, 324B, 424B) from the light source (124). The first light guide (122A) has a guide proximal end (122P). The second light guide (122A) receives the light energy (224A, 224B, 324A, 324B, 424B) from the light source (124). The second light guide (122A) has a guide proximal end (122P). A multiplexer (223) directs the light energy (224A, 224B, 324A, 324B, 424B) toward the guide proximal end (122P) of the first light guide (122A) and the guide proximal end (122P) of the second light guide (122A). The optical alignment system (257) determines an alignment of the light energy (224A, 224B, 324A, 324B, 424B) relative to at least one of the guide proximal ends (122P). The optical alignment system (257) adjusts the positioning of the light energy (224A, 224B, 324A, 324B, 424B) relative to the at least one of the guide proximal ends (122P) based at least partially on the alignment of the light energy (224A, 224B, 324A, 324B, 424B) relative to the at least one of the guide proximal ends (122P).

An endoscopic device includes a single-use cannula configured for insertion through a cervix into a uterus, a camera secured to a distal end region of the single-use cannula for acquiring images of the uterus, a connection hub secured to a proximal end region of the cannula, a reusable display configured to present the images acquired by the camera and that is securable to the connection hub, and a handle secured to the connection hub. The handle is pivotable between a first position in which the handle is stowed along the connection hub and arranged to prevent attachment of the reusable display to the connection hub and a second position in which the handle is deployed to an orientation that is antiparallel to the connection hub and arranged to permit attachment of the reusable display to the connection hub.

An apparatus and method to enable clinicians to verify needle or catheter location within an anatomic site by relying upon combined sensing of two signals, such as a pressure signal and a heart rate pulse signal, in which the detection of a correlation between both signals is identified to confirm location of the needle or catheter.

A suction catheter assembly structured to be movably positioned within a lumen of the body including an elongated base having a channel extending interiorly along the length thereof and further structured to connect the channel to a source of negative pressure. A tip is fixedly or removably connected to a distal end of said base and includes an inlet port and a flow path disposed in fluid communication with the channel. A viewing structure is connected to and movable with the base and is oriented relative thereto to define a line of sight providing observation of a path of travel of said base within the body lumen or medical tubing and is disposed laterally outward from at least a majority of a length of said flow path and the inlet port in substantially aligned, parallel relation to a central axis of said channel.
