A biopsy site marker includes a carrier, and a marker element. The marker element includes a primary coil, a first anchor and a second anchor. The primary coil is disposed within the carrier. At least a portion of the first anchor and the second anchor extend outwardly from opposite sides of the carrier. The first anchor and second anchor are configured to move relative to the primary coil to engage tissue at a biopsy site.

A device for sealing an opening through a biologic tissue membrane against leakage. The device includes an implantable fluid sealing plug including a structural hydrogel. The fluid sealing plug is configured to be positioned at least partially within the opening through a biologic tissue such as a membrane. The fluid sealing plug is configured to increase in diameter upon absorbing a fluid, and the increase in diameter of the fluid sealing plug upon absorbing the fluid seals the opening through a biologic tissue membrane.

A method for tracking an interventional medical device in a patient includes interleaving, by an imaging probe external to the patient, a pulse sequence of imaging beams and tracking beams to obtain an interleaved pulse sequence. The method also includes transmitting, from the imaging probe to the interventional medical device in the patient, the interleaved pulse sequence. The method further includes determining, based on a response to the tracking beams received from a sensor on the interventional medical device, a location of the sensor in the patient.

A biopsy probe mechanism includes an elongate sample receiving member having a longitudinal axis and a sample receiving notch. A cutting cannula is arranged coaxially with the elongate sample receiving member. The elongate sample receiving member and the cutting cannula are movable relative to one another along the longitudinal axis between a first relative position and a second relative position. A plurality of echogenic features include a first echogenic feature established on the elongate sample receiving member and a second echogenic feature established on the cutting cannula. The first echogenic feature is in longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the first relative position. The first echogenic feature is out of longitudinal alignment with the second echogenic feature when the elongate sample receiving member and the cutting cannula are in the second relative position.

Devices, systems, and methods are provided for image-guided interventional procedures and other uses. Nested articulated catheter shaft systems may have an imaging catheter with an ultrasound transducer supported by a fluid-driven articulated sheath portion. Drive fluid can be transmitted distally along an asymmetric sheath via eccentric passages to an articulated portion of the imaging catheter distal of a port. An articulated shaft supporting a therapeutic tool can be advanced within a working lumen of the imaging sheath to the port so that the tool is within a field of view of the transducer. The fluid transmission channels may take much less cross-sectional area of the sheath than a mechanical pull-wire system, allowing the nested sheath/shaft system to provide safer access to a chamber of the heart and to facilitate precise independent control over 3D ultrasound imaging and image-guided structural heart therapies or the like.

The Cervical Dilator is an improved tool for dilating a woman’s cervix prior to gynecological surgeries. The Cervical Dilator comprises a solid dilator with a first diameter and a series of hollow dilators. The series of hollow dilators comprises a plurality of hollow dilators of increasing size. A first hollow dilator has a second diameter that may be 1 mm larger than the first diameter. A second hollow dilator has a third diameter that may be 1 mm larger than the second diameter. A third hollow dilator has a fourth diameter that may be 1 mm larger than the third diameter. Thereby, upon insertion of the next hollow dilator in the series, the dilation of the cervix is increases by 1 mm.

Surgical robot systems, anatomical structure tracker apparatuses, and US transducer apparatuses are disclosed. A surgical robot system includes a robot, a US transducer, and at least one processor. The robot includes a robot base, a robot arm coupled to the robot base, and an end-effector coupled to the robot arm. The end-effector is configured to guide movement of a surgical instrument. The US transducer is coupled to the end-effector and operative to output US imaging data of anatomical structure proximately located to the end-effector. The least one processor is operative to obtain an image volume for the patient and to track pose of the end-effector relative to anatomical structure captured in the image volume based on the US imaging data.

A device for use with a uterine tamponade balloon catheter apparatus, such as the Bakri postpartum hemorrhage balloon, is disclosed. The device comprises a stylet comprising a hub at its proximal end and an atraumatic tip at its distal end. The device is configured to be removably coupled to the tamponade balloon catheter apparatus to aid in the insertion and positioning of the tamponade balloon catheter within the uterine cavity, allowing the balloon to function as intended for the control and management of postpartum hemorrhage and uterine bleeding. The tamponade balloon catheter includes an echogenic element to aid in visualization by ultrasound during insertion and use. Methods of use of the device are also disclosed.

An image-guided robotic intervention system (“IGRIS”) may be used to perform medical procedures on patients. IGRIS provides a real-time view of patient anatomy, as well as an intended target or targets for the procedures, software that allows a user to plan an approach or trajectory path using either the image or the robotic device, software that allows a user to convert a series of 2D images into a 3D volume, and localizes the 3D volume with respect to real-time images during the procedure. IGRIS may include sensors to estimate pose of the imaging device relative to the patient to improve the performance of that software with respect to runtime, robustness, and accuracy.

A device (10) for capturing a guide wire (50) comprises a snaring device (20, 30) and an auxiliary catheter (40). The auxiliary catheter (40) is configured to slidingly accommodate the guide wire to be caught so as to extend a distal end (47) thereof beyond the distal end of the guide wire in order to be caught by the snaring device (20, 30) while the guide wire (50) is in a retracted position in the auxiliary catheter (40). The auxiliary catheter preferably comprises a portion which is at least partially echo-transparent and/or radio-transparent and an end portion (44) which is radio-opaque and/or echo-opaque.
