An implantable tissue marker device is provided to be placed in a soft tissue site through a surgical incision. The device can include a bioabsorbable body in the form of a spiral and defining a spheroid shape for the device, the spiral having a longitudinal axis, and turns of the spiral being spaced apart from each other in a direction along the longitudinal axis. A plurality of markers can be disposed on the body, the markers being visualizable by a radiographic imaging device. The turns of the spiral are sufficiently spaced apart to form gaps that allow soft tissue to infiltrate between the turns and to allow flexibility in the device along the longitudinal axis in the manner of a spring.

A marker delivery device includes a housing, a flexible push rod, and a wheel. The push rod includes a first transverse dive surface and a deployer tip. The deployer tip is configured to receive a biopsy site marker. The wheel includes a second transverse drive surface. The first transverse drive surface is configured to be driven by the second transverse drive surface to translate the push rod distally.

Multimodality markers for delineation of a region of interest (ROI) within a patient's body are disclosed. The markers may comprise a hermetic bio-compatible container and an external element that is associated with the hermetic bio-compatible container. A unique collective identification (ID) is assigned to each of the markers. The collective ID can comprise a visible component seen on an imaging system and an electronic component stored in a microelectronic chip and embedded within the hermetic bio-compatible container.

A method of making an intracorporeal marker, including the method steps of providing a core having a first material with porous hydroxyapatite; and completely covering the core an outer region having a second material with less porous hydroxyapatite, wherein ultrasonic or radiative imaging reveals a difference between the marker and tissue.

The invention discloses an integrated tumor resection instrument and a simulation training system. The resection device comprises an imaging system, a minimally invasive incision, a processor, an operating device, a resection executing mechanism and a positioning control device. The operating device is connected to the input end of the processor, the resection actuating mechanism is provided with a resecting driver, and the positioning control device and the resecting driver are both connected to the output end of the processor; the simulation training system comprises the steps of designing a manikin; arranging the imaging system; integrated resection. The resection device can resect the whole tumor along the edge of the tumor, thereby avoiding the incomplete resection and even tumor recurrent caused by crushing in the process of resecting the tumor. The simulation training system can train an operator to quickly master the resection skill and operation of various positions.

Disclosed herein are tissue marking devices and methods that enables marking a target tissue more than 24 hours prior to surgery. The tissue marking device includes a hook assembly having a compressed configuration and a deployed configuration and a handle assembly for positioning the hook assembly in a targeted tissue. The hook assembly may include a hook body comprising at least two hooks and a thread connected to the hook body. The handle assembly may include a handle body, a needle having a lumen, and a stylet having a lumen.

The combination of a marker system with binocular AR glasses to create a soft tissue procedure system used for surgery, biopsies, etc. A marker localization system is functionally integrated with augmented reality (AR) glasses. This soft tissue system can be applicable for AR surgeries in soft tissues involving mobile and static anatomies anywhere in the body, such as for example, breast, soft tissue, lungs, lymph nodes, liver surgeries, etc. By the placement of single or multiple markers and localizing the markers with a locator, such as a hand-held locator as a non-limiting example, the above-mentioned system provides a real-time intraoperative coordinate frame for the virtual projection of the markers (and the associated ROI) on/in the surgical field/biopsy field of view, using commercial off-the-shelf computer hardware (laptops, tablets, etc.) for the required image processing.

A detection system and method uses an implantable magnetic marker comprising at least one piece of a large Barkhausen jump material (LBJ). The marker is deployed to mark a tissue site in the body for subsequent surgery, and the magnetic detection system includes a handheld probe to excite the marker below the switching field for bistable switching of the marker causing a harmonic response to be generated in a sub-bistable mode that allows the marker to be detected and localised. The marker implanted may also be shorter than the critical length required to initiate bistable switching of the LBJ material.

An imaging system, such as a DBT system, capable of providing an operator of the system with information concerning the location, magnitude and direction of motion detected by the system during performance of the scan to enhance image processing. The imaging system provides the motion information to the operator directly in conjunction with the images processed by the imaging system thereby providing the operator with sufficient information for decisions regarding the need for additional images for completing the scan with the imaging system before the patient is discharged, or even before the breast is decompressed.

Described herein are devices for placement in surgically created soft tissue spaces, potential spaces, or cavities. The implantable devices generally include a bioabsorbable body having an open framework that facilitates attachment of tissue thereto in a manner that helps avoid post-surgical deformities. Methods for using the implantable devices in oncoplastic surgery are further described.
