A guide device for cannulas for the collection of micro-fragmented subcutaneous adipose tissue includes a handle which has an axial cavity intended to house a syringe equipped with a collection cannula. The axial cavity has an open proximal end, an open distal end and a central axis. A lip protrudes cantilevered from the distal end at a distance from the central axis and from said cannula. An intermediate anti-flexion element of the cannula is arranged between the handle and the lip.

Devices and methods for the treatment of chronic total occlusions are provided. One disclosed embodiment comprises a method of facilitating treatment via a vascular wall defining a vascular lumen containing an occlusion therein. The method includes inserting an intramural crossing device into the vascular lumen, positioning at least the distal tip of the crossing device in the vascular wall, advancing an orienting device over the crossing device such that an orienting element of the orienting device resides in the vascular wall, inserting a reentry device, and re-entering the true vascular lumen.

Described here are methods and systems for the manipulation of ovarian tissues. The methods and systems may be used in the treatment of polycystic ovary syndrome (PCOS). The systems and methods may be useful in the treatment of infertility associated with PCOS.

A needle guiding bracket with adjustable angles is provided, comprising a bracket body, a mounting base, and an angle block; the angle block and the mounting base are rotationally connected at corresponding first ends, and a cooperating limiting structure is provided between the angle block and the mounting base to enable the angle block and the mounting base to only relatively rotate; a second end of the angle block is provided with at least one elastic arm having raised positioning platforms; a second end of the mounting base is provided with at least one group of angle gear grooves for the raised positioning platforms to be embedded therein; and the angle block is further provided with an elastic element which applies elastic force to the elastic arms so as to enable the raised positioning platforms to be embedded within the angle gear grooves.

A device for adjusting biopsy angles and a biopsy needle guide are provided. The device for adjusting biopsy angles comprises an angle fixing base and a needle guiding base, the needle guiding base being rotatably connected with the angle fixing base at their first ends, the needle guiding base having a needle tract for guiding a biopsy needle, wherein an U-shaped limiting assembly formed on one side of the needle guiding base surrounds a angle fixing sheet extending from the angle fixing base at their second ends, and a positioning adjuster mounted on the U-shaped limiting assembly is movably engaged with positioning holes on the angle fixing sheet so as to be inserted into the positioning holes or be released out of the positioning holes. The needle guiding base can be rotated at a large angle to disengage from the angle fixing sheet, and is convenient for cleaning.

One or more devices, systems, methods and storage mediums for performing medical procedure (e.g., needle guidance, ablation, biopsy, etc.) planning and/or performance, and/or for performing guidance of multiple probes or multiple needles, are provided. Examples of applications for such devices, systems, methods and storage mediums include imaging, evaluating and diagnosing biological objects, such as, but not limited to, lesions and tumors, and such devices, systems, methods and storage mediums may be used for radiotherapy applications (e.g., to determine whether to place seed(s) for radiotherapy). Even in instances where communication between a medical tool or needle guidance device and a system is wireless or wired, preferably guidance information is still gathered and transmitted, especially in instances where wireless or wired communication signals are intermittent or interrupted.

An ultrasonic probe of an embodiment includes a head part. The head part includes a plurality of ultrasonic elements that output ultrasonic waves and receive reflected waves of the output ultrasonic waves. The head part is provided with a through hole for guiding a puncture needle and a slit for guiding the puncture needle to the through hole.

A biopsy device includes a cannula and a specimen collector. The cannula has a proximal end and a longitudinal axis. The specimen collector contains the proximal end of the cannula. The specimen collector has a removable sample receiving cartridge that is removable along the longitudinal axis of the cannula to expose the proximal end of the cannula.

In a handle unit for interventional procedure, a master device for interventional procedure, and a remote control interventional procedure system, the handle unit is gripped by an operator. The handle unit includes a gripper, a mode selection module and a linear motion module. The gripper is gripped by the operator. The mode selection module is equipped to the gripper, and selects one of motion modes including a linear motion mode, a rotational motion mode and a plane motion mode. The needle linearly moves with one degree of freedom in the linear motion mode. The needle rotationally moves with two degrees of freedom in the rotational motion mode. The needle moves in a plane with two degrees of freedom in the plane motion mode. The linear motion module performs the linear motion of the needle based on the selection of the mode selection module, and is equipped to the gripper.

A bone marrow harvesting device can include: a hub inserted into a bone marrow cavity; a catheter inserted into the hub and having a syringe detachably connected to one side thereof; and a holder connected to one end of the catheter such that the catheter is movable along the longitudinal direction. The bone marrow harvesting device, when harvesting bone marrow, can not only easily and stably move the position of a catheter inserted into a bone marrow cavity, but can also harvest the bone marrow in a state where the catheter is stably fixed after the position of the catheter is moved.
