An instrument for therapeutically cytotoxically ablating parathyroidal tissue is disclosed. A substance is capable of transforming the parathyroid gland from overproduction of parathyroid hormone when the substance's quantity exceeds a set amount, and is capable of transforming the parathyroid gland from overproduction only when activated by application of sufficient units of an electromagnetic energy having a frequency ranging from 400 THz to 30 PHz when the substance's quantity is below the set amount. A delivery device is operable to introduce the substance into the parathyroidal tissue and to quantitatively limit the quantity to below the set amount. An energy device is operable to apply units of the electromagnetic energy after the substance has been introduced. A sensor is operable to monitor the activation of the substance as the electromagnetic energy is applied. The energy device is further operable to modulate applying the electromagnetic energy when the substance has been activated.

An accurate and precise surgical guide for dental procedures, especially a procedure involving a subject with few or no teeth as well as methods for making and use of such guides.

The invention provides a plantar plate repair device to facilitate the appropriate placement of sutures during a plantar plate repair. The device comprises a shaft terminating in a footprint projecting angularly from the shaft, the footprint further defining an opening through which a needle is threadable. The shaft further includes a guide slidable on the shaft to operatively clamp the plantar plate between the guide and footprint. A needle receiving guide hole is provided on the guide to operatively guide a needle through the opening in the footprint to pass a length of suture from the needle through the plantar plate.

An intervention guidance device (10) includes a main body portion (100) and a guidance portion (200). The guidance portion (200) has a contracted configuration and an expanded configuration. In the expanded configuration, the guidance portion (200) has a central area (201) and a closed outer edge (202). In the contracted configuration, the outer edge (202) is farther away from the main body portion (100) than the central area (201), and the guidance portion (200) is restorable from the contracted configuration to the expanded configuration. In the intervention guidance device (10), the radial dimension of the guidance portion (200) is larger than the distance between the chordae tendineae, so that an effective access path that does not cross the chordae tendineae can be established, the subsequent implantation of a heart valve prosthesis does not pass through the chordae tendineae, and the success rate of a heart valve prosthesis implantation surgery can be improved.

A catheter for ablation including a catheter shaft, a balloon at a distal end of the catheter shaft, and a microporous portion. The balloon is configured to support conductors and electrodes and contain a fluid. The microporous portion is coupled to the balloon to allow the fluid to flow out of the balloon and includes a plurality of apertures configured to prevent large air bubbles from exiting the balloon.

An apparatus includes a shaft assembly, an end effector, and a sensor. The shaft assembly defines a longitudinal axis. The end effector is positioned at a distal end of the shaft assembly. A portion of the end effector is offset from the longitudinal axis. The sensor is configured to generate a signal in response to a magnetic field. The signal is configured to indicate a position of the end effector within three-dimensional space. The sensor is coaxially positioned about the longitudinal axis.

A vaginal device is described. A conformable vaginal insert is shaped for insertion into a vaginal cavity of a female human. A contact point is configured to change a shape of the insert. A sensor is configured to measure and to relay characteristics of the vaginal cavity and the surrounding and supportive structures of the vaginal cavity. A processor is configured to control the contact point to adjust the shape of the insert, generate a treatment for the vaginal cavity and the surrounding structures of the vaginal cavity and the supportive structures of the vaginal cavity comprising a vaginal cavity profile generated from the measured characteristics, store the measured characteristics and the vaginal cavity profile, and based on the stored measured characteristics and the stored vaginal cavity profile, automatically modify the shape of the insert by control of the contact point to provide the treatment to the vaginal cavity.

The subject matter described herein is designed to facilitate and overcome the limitations of rehabilitation of body changes and to improve, retrain, and facilitate body functions micturition, defecation, sexual pleasure, anatomic prolapse, and their related bodily dysfunctions. The devices can include sensor, optics, send and receive transmitters, local positioning system (LPS) or sensors, computing devices and display elements and devices, which can be powered by bio-generating machines and devices.

A method for manipulating tissue of a patient includes a surgical instrument having a handle assembly, a shaft assembly, and an end effector. The method includes positioning a tissue within a gap between a cartridge and an anvil and against a guide pin to laterally position the tissue relative to the cartridge and the anvil. The method also includes moving a retaining pin from an open position to a closed position to capture the tissue and moving the cartridge toward the anvil in a closed configuration. Furthermore, the method includes inhibiting deflection of a distal end portion of the end effector wherein at least at least one of the guide pin or the retaining pin connects to the distal end portion. The method further includes forming a plurality of staples within the tissue and cutting the tissue with a knife.

A tool for creating an incision at a surgical site includes a body for use with a robotic end effector having a proximal end and a distal end, and a blade positioned at the distal end of the body, the blade having a proximal end and a distal end, the blade having a cutting edge defining a first portion extending outwardly from or adjacent to the proximal end to a maximum width and a second portion extending inwardly from the maximum width to a sharp distal tip.
