A non-transitory computer readable medium containing instructions that when executed by at least one processor, cause the at least one processor to perform operations for monitoring partitioning of a medical instrument during an endovascular procedure. The operations may further be configured to obtain an input to activate a partitioning mechanism associated with a medical instrument within a lumen of a catheter, the catheter being positioned within a body. Further, embodiments may be configured in response to the input, to activate the partitioning mechanism. The operations may further be configured, following the activation, to obtain partitioning outcome data. The operations may determine, based on the partitioning outcome data, whether the medical instrument may be in a severed state or a connected state. The operations may, if the severed state of the medical instrument is detected, output a success notification. Some embodiments may be configured, if the connected state of the medical instrument is detected, to output at least one of (i) a control signal to vary activation of the partitioning mechanism or (ii) an instruction to reposition the medical instrument relative to the partitioning mechanism.

Consistent with disclosed embodiments, systems, devices, methods, and computer readable media for filling a hollow body structure may be provided. In some implementations, an endovascular instrument for filling a hollow body structure may be provided and may include an elongated member configured to exhibit differing coiling properties along a length thereof. The elongated member may include a first region configured to bend within the hollow body structure to form a stabilizing frame. The elongated member may also include a second region located proximal to the first region and configured to bend, after formation of the frame, substantially within the frame, thereby forming a curved mass substantially within the frame. The first region and the second region may be interconnected. The embodiments may further include at least one structural property that differs between the first region and the second region.

A method of marking a tumor includes positioning a surgical instrument adjacent breast tissue, generating an image of a tumor in the breast tissue on a display using an ultrasonic probe of the surgical instrument, aligning a needle of the surgical instrument with the tumor using the image of the tumor generated on the display, deploying the needle from the ultrasound probe into the breast tissue, and deploying an elongated tissue marker from the needle into the tumor, thereby fixing a distal portion of the tissue marker in the tumor.

Provided herein are methods of documenting breast tissue in an area of interest in a subject in need thereof using automated breast ultrasound. The methods comprise using surface markers that can clearly identify the area of interest in a resulting 3-D image without introducing artifacts that obscure the tissue intended for examination.

Disclosed herein, in some embodiments, are medical device systems including an elongate medical device having a proximal end including one or more sensor connectors, a distal end including one or more sensors or emitters communicatively coupled to the one or more sensor connectors, and a drive connector including one or more sensor connector attachments configured to detachably couple to the one or more sensor connectors. The one or more sensor connector attachments can be configured to drive the one or more sensors or emitters of the elongate medical device.

A breast biopsy marker includes a catheter shaft and a bioabsorbable balloon. The catheter shaft has a lumen, a proximal tube portion, and a distal tube portion. The proximal tube portion is joined to the distal tube portion by a frangible link. The distal tube portion has a one-way valve located in the lumen. The bioabsorbable balloon is fixedly connected to the distal tube portion to define a balloon assembly. The bioabsorbable balloon is configured for fluid communication with the lumen of the catheter shaft at a location distal to the one-way valve of the distal tube portion of the catheter shaft. The balloon assembly is configured to be separated from the proximal tube portion of the catheter shaft by breaking the frangible link.

Transcervical access systems for providing transcervical movement of fluids are described. The transcervical access systems are effective for transferring a broad range of fluids, including the delivery of hydrogel precursors, saline, and imaging fluids, to the uterine cavity. The transcervical access systems are also effective for removing fluids from the uterine cavity, such as residual bodily fluids, residual fluids from a procedure, or tissue. The transcervical access systems described include flow limiters, such as egress limiters and/or cervical plugs. Methods of use of the transcervical access systems are also described. Methods include using the transcervical access systems to transcervical access the uterine cavity and install hydrogel. The transcervical access systems and associated methods can be useful for providing degradable hydrogel in the uterine cavity, including the cervical canal, for the prevention of adhesions following intrauterine procedures.

A surgical robotic system includes a robotic arm, an injection needle supported by the robotic arm, a localization system, an imaging system, at least one control unit. The at least one control unit is configured to perform at least one controlled loop carried out after a dispense of cement with the injection needle, in the region of interest of a patient. This controlled loop includes imaging the region of interest, with the imaging system, to provide an updated set of imaging data; using at least partially the updated set of imaging data to calculate an updated set of injection parameters; and using at least one parameter of the updated set of injection parameters to control the dispense of cement through the injection needle. Also disclosed is a method for controlling a surgical robotic system.

Multiple vascular wall penetrations are formed and sealed in a single blood vessel, typically a vein, for performing cardiac and other catheter-based procedures. Access sheaths are placed in two or more tissue tracts each having a vascular wall penetration at a distal end and into a lumen of the blood vessel. A catheter is advanced though each of the access sheaths to perform a therapeutic or diagnostic procedure. A vascular closure device is introduced through each access sheath, typically sequentially, and an occlusion element at a distal end of the device is deployed against an inner wall of the blood vessel in a manner so that the adjacent access sheath does not interfere or overlap with the deployed occlusion element. The vascular penetration at the distal end in that tissue tract may then be sealed prior to using another vascular closure device to seal a caudally adjacent vascular wall penetration.

Disclosed are methods and devices for bidirectional crossing of a vascular obstruction in a patient. The method includes the steps of advancing a first catheter transvascularly in a first (e.g., retrograde) direction towards a vascular obstruction, the first catheter having a first central lumen in communication with a first side port. A second catheter is advanced transvascularly in a second, opposite (e.g., antegrade) direction towards the obstruction, the second catheter having a second central lumen in communication with a second side port. The first and second side ports are aligned to place the first central lumen in communication with the second central lumen; and a wire is advanced through the first and second side ports such that a first end of the wire is on a first side of the obstruction and a second end of the wire is on a second side of the obstruction.
