An apparatus for use with a minimally invasive medical procedure into human breast tissue includes a cannula and an obturator. The cannula includes an open distal end, a lateral opening proximate to the open distal end, and a longitudinal lumen communicating with the lateral opening and the open distal end. The lumen has a non-circular cross-section. The obturator is sized for insertion into the cannula. The obturator has a distal end extending from the open distal end of the cannula when the obturator is inserted fully into the cannula. The obturator has a recess proximate of the distal end of the obturator. The recess is positioned along a portion of the length of the obturator to align with the lateral opening of the cannula when the obturator is inserted fully into the cannula.

A brachytherapy template adaptor for performing brachytherapy procedures using needles smaller in diameter than the template is designed to accommodate. Additionally, a kit for adapting a brachytherapy template is provided.

Systems and methods for mitigating the formation of heterotopic ossification lesions by delivering a neuromuscular inhibitor employ a delivery device to distribute injection of the neuromuscular inhibitor. A delivery device for delivering the neuromuscular inhibitor can include an injector body, a device body for spacing the injector body from a target delivery location, and a plurality of needles; or can include an injector guide having multiple guide holes and an injector needle for delivering the neuromuscular inhibitor via the guide holes.

A system and associated instruments for locating, and accurately and controllably delivering, a device to an area sufficiently near a bone defect using anatomical landmarks is provided. The instruments allow the surgeon to navigate to the area around the bone defect quickly and easily, while so facilitating proper insertion of the device. In some embodiments, the defect is located on a femur. Guide instruments having a plurality of device portals are also provided for use as standalone instruments or as accessories to the system. In addition, a protective guide sleeve is provided for the insert of small diameter devices.

Applicator for injecting a bulking agent at one or more selected submucosal positions in a periurethral tissue of a female patients' urethra. The applicator comprises a lance, such as a cystoscope with a distal end provided with one or more optical sensors, and a needle guide with a bore receiving the lance. The needle guide comprises needle channels at different angular positions, each needle channel extending between a needle entrance surface and an opposite shoulder surface. The needle channels are oriented to direct a needle via external peripheral tissue of the urethral meatus to a submucosal position at a urethra section, e.g., within the optical scope of the optical sensor.

The present disclosure relates to a guide assembly. The guide assembly includes a guide having a body having a first set of marks and a joint including at least one through hole, the joint configured for sliding along the length of the body; and a first surgical device having a second set of marks, wherein the guide is coupled to the first surgical device and a longitudinal axis of the through hole is co-radial with a mark of the second set of marks when the joint is located at a mark of the first set of marks. Other guides are also disclosed.

A system for automatically identifying a needle insertion location from a medical diagnostic image, such as an MRI image, and providing a visual indication of the needle insertion location is disclosed. A grid plate is located proximate to an anatomical region and is preferably incorporated in an MRI support structure utilized to immobilize the anatomical region. An MRI scanner obtains an MRI image of the anatomical region, and an MRI technician places a marker on the MRI image, identifying the needle insertion location. The MRI image and the marker are transferred from the MRI scanner to another device, such as a tablet computer, which is configured to convert the MRI image and the marker to coordinates and an insertion depth. A visual indicator is located proximate to or integrated with the grid plate that provides the needle insertion coordinates and insertion depth to the MRI technician.

The instant invention is comprised of radiographic grids and an adjustable needle guide to facilitate the placement of an introductory needle using a two-dimensional aiming using an imaging needle guide comprising a proximal grid including a body, a top side, a bottom side, one or more radiopaque rings, and a central aperture extending through the body from the top side to the bottom side, a distal grid including a body, a top side, a bottom side, one or more radiopaque rings, and a central aperture extending through the body from the top side to the bottom side, and a needle.

A method of controlling electric fields created by a plurality of electrodes. The method includes repetitively applying multiple sets of voltages to at least some of a plurality of electrodes over a treatment period to achieve and maintain a target temperature, the at least some of the electrodes being treatment electrodes. The sets of voltages may be in patterns such that a unique current pattern between electrodes is created for each set of voltages, resulting in temperature averaging. The voltage at each electrode may be determined based on a temperature of an adjacent electrode. The voltage at each electrode may also or alternatively be determined based on an estimated voltage at the electrode.

Systems, devices, and methods for performing Lapidus bunionectomy procedures are disclosed. An example method includes inserting a plurality of metatarsal pins into the first metatarsal at a first predetermined spacing relative to the first tarsometatarsal (TMT) joint, excising the first TMT joint by cutting the bases of the first metatarsal and the first cuneiform proximate the first TMT joint, inserting a plurality of cuneiform pins into the first cuneiform at a second predetermined spacing relative to the first TMT joint, compressing the first TMT joint using a compressor block such that a cut face of the first metatarsal contacts a cut face of the first cuneiform, and fixing the first TMT joint using a bone plate and a plurality of bone screws. At least one of the plurality of bone screws may be a cross screw extending at an angle of less than 90 degrees relative to the bone plate and may anchor the resected first TMT joint to the second metatarsal or the second cuneiform to prevent recurrence of the bunion.
