A puncturing device and an anchoring device, the puncturing device including: a puncturing needle, an inflatable anchoring balloon, and a catheter which passes through a proximal end and distal end of the anchoring balloon, the puncturing needle being movably accommodated within the catheter; in a filled state, a central area of an end portion of the distal end of the anchoring balloon is depressed towards the proximal end to form a depressed area, and a distal end of the catheter is located within the depressed area. The anchoring device includes the anchoring balloon and the catheter. The puncturing device may improve the accuracy and success rate of puncturing, and after puncturing is complete, an expansion balloon may be transported along a guide wire to expand a puncturing opening by simply withdrawing the puncturing needle and a push rod.

A sleeve extractor includes a cylindrical body having a distal end and a proximal end, one or more longitudinally-extending fingers defined in the body, and a tab provided on an end of each finger and receivable within a notch defined in a shaft adapter or a shaft of a surgical tool, the notch being located proximal to a proximal end of a sleeve. The sleeve is removed by locating the tab of each finger in a corresponding notch and retracting the body and the sleeve distally relative to the shaft adapter or the shaft.

An endoscopic device for biportal endoscopic spinal surgery is proposed. The device includes: a guide tube as a hollow tubular member extending in a longitudinal direction and having a front end thereof reaching a target site in a patient's body when being used, the guide tube accommodating a probe of an endoscope inserted therein; a saline solution guide part mounted on a rear end of the guide tube and guiding a saline solution injected from an outside to an inside of the guide tube; and an adapter part positioned at the rear end of the guide tube and guiding the probe of the endoscope to use to the guide tube.

An insertion tool for creating a subcutaneous pocket and implanting a device in the pocket. The tool may include a cannula extending from a handle, a dissector tip disposed at a distal end of the cannula, and a rod. The cannula and dissector tip may create the pocket. The cannula may include a passage and an opening into the passage, and the cannula may be disposed in the passage and move along the passage between a retracted position and an extended position. The rod and the cannula may be configured such that, when the rod is at the retracted position, the cannula holds the device in the passage, and as the cannula moves from the extended position to the retracted position, the rod forces the device through the opening at the distal end of the cannula, at least partially out of the cannula, and at least partially into the pocket.

A needle or stylet has a tip contour with a reverse back bevel curved toward the longitudinal axis of the needle or stylet. The needle has a flexible intermediate portion and/or a two-part construction in which a distal portion of the needle to crimped onto a proximal portion of the needle. The needle or a stylet is combined with a spring mechanism in the hub of the needle or stylet assembly. The spring mechanism positions the tip of the needle or stylet in a middle position extending from the distal end of the assembly, allows the needle or stylet to be moved into a spring loaded fully retracted configuration within the assembly as the septal wall is tented, and then releasing the spring loaded needle or stylet as the needle or stylet penetrates the septal wall. A method of using a needle or stylet with a spring mechanism is included.

Surgical systems and methods for percutaneously inserting surgical devices, such as during glenoid labrum repairs or rotator cuff repairs of the shoulder, for example, may include a cannula and a cutting obturator insertable through the cannula. The cutting obturator may include a cutting tip configured for penetrating and dilating tissue during a percutaneous insertion into a joint space.

According to an aspect of the present disclosure, an end effector for use with a surgical device is provided. The end effector includes a driver, a clip assembly, a needle assembly, and biasing element. The clip assembly is disposed in mechanical cooperation with the driver. Rotation of the driver results in longitudinal translation of the clip assembly. The needle assembly is selectively engaged with the clip assembly. The biasing element is disposed in mechanical cooperation with the needle assembly and is configured to bias the needle assembly proximally.

A puncturing device and an anchoring device, the puncturing device including: a puncturing needle, an inflatable anchoring balloon, and a catheter which passes through a proximal end and distal end of the anchoring balloon, the puncturing needle being movably accommodated within the catheter; in a filled state, a central area of an end portion of the distal end of the anchoring balloon is depressed towards the proximal end to form a depressed area, and a distal end of the catheter is located within the depressed area. The anchoring device includes the anchoring balloon and the catheter. The puncturing device may improve the accuracy and success rate of puncturing, and after puncturing is complete, an expansion balloon may be transported along a guide wire to expand a puncturing opening by simply withdrawing the puncturing needle and a push rod.

A system for measuring a pressure in a vein includes a needle sized and shaped to be inserted through a working channel of an endoscope. The needle is extending longitudinally and including a channel extending longitudinally therethrough. The system also includes a pressure sensing device including a longitudinally extending body sized and shaped to be slidably inserted through the channel of the needle and a sensor mounted on a distal portion of the body and connected to a proximal portion of the pressure sensing device via a connection cable. The sensor is configured to detect information corresponding to a pressure of a flow of blood through a vein.

A system includes a sensor applicator, a sensor control device arranged within the sensor applicator and including an electronics housing and a sensor extending from a bottom of the electronics housing, and a cap coupled to one of the sensor applicator and the sensor control device, wherein the cap is removable prior to deploying the sensor control device from the sensor applicator.
