A system for introducing a surgical instrument through a tissue lumen having: a surgical instrument; a sheath for preventing contamination of the tissue lumen; a dilator for dilating bodily tissue having an elongated body for positioning the dilator and a tapered section for facilitating dilation of the tissue lumen; and a cone having conical body that tapers from the proximal end to the distal end and facilitates insertion of the cone and the surgical instrument through the tissue lumen, an axial bore that extends longitudinally through the cone and receives an anvil retainer, a collar that engages the distal end of the surgical device and prevents lateral movement of the cone, grooves that engage the surface of the tapered section and reduce the friction between the cone and the tissue lumen, a securing device for securing the cone to the surgical instrument, and a retrieval device for retrieving the cone from a bodily cavity.

An intervention system employs an optical shape sensing tool (32) (e.g., a brachytherapy needle having embedded optical fiber(s) and a grid (50, 90) for guiding an insertion of the optical shape sensing tool (32) into an anatomical region relative to a grid coordinate system. The intervention system further employs a registration controller (74) for reconstructing a segment or an entirety of a shape of the optical shape sensing tool (32) relative to a needle coordinate system, and for registering the needle coordinate system to the grid coordinate system as a function of a reconstructed segment/entire shape of the optical shape sensing tool (32) relative to the grid (50, 90) (i.e., reconstruction of a segment/entire shape of the OSS needle inserted into/through the grid serving as a basis for the grid/needle coordinate system registration).

A mechanism facilitates the insertion of radioactive sources/source strands into soft tissue, such as breast tissue, that improves the reproducibility of the procedure and ensures that the sources are reliably and consistently inserted in an exact position per a patient prescription treatment plan from patient to patient as well as improve the ease-of-use of the device and procedure.

A targeting set for use with positioning a biopsy device within a patient. The targeting set includes an obturator and an actuator. The actuator includes a housing and a lock array. The lock array extends inwardly within a hollow interior defined by the housing. The obturator is configured for insertion into the housing of the actuator such that at least a portion of the obturator engages the lock array. The lock array is configured to selectively lock the obturator in a plurality of axial positions relative to the housing.

A system for treating obstructive sleep apnea (OSA) is described. The system may include a locking device having a size and shape selected to couple to skin along a jaw of a patient. The locking device may be configured to receive at least one of a needle or an introducer for insertion into a tongue of the patient for lead placement of a lead for OSA treatment, and lock at least a portion of the at least one of the needle or introducer in place to reduce movement of the needle or introducer within the tongue.

A method of performing a transperineal biopsy procedure including the steps of: inserting an access needle into one of a plurality of needle receiving ports of a displacement member of a transperineal biopsy guide that is secured to the transrectal ultrasound probe; securing the access needle to the displacement member such that a position of the access needle relative to the displacement member is maintained; imaging the prostate of the patient with the transrectal ultrasound probe; inserting the access needle into the perineal access site of the patient; and inserting the biopsy needle through the access needle and into the prostate of the patient.

The present invention relates to a needle guide device having a housing, a core needle, a guide needle assembly having a slide or a push button and a spring for biopsy, which is capable of easily separating a guide needle and a core needle.

Systems, methods, and devices are provided for assisting or performing guided interventional procedures using custom templates. The system uses pre-procedure scans of a patient's anatomy to identify targets and critical structures. A template is then manufactured containing guide elements. During a procedure, the template may be aligned to the patient and instruments passed though the guide elements and into various targets. The template may be aligned using one or more of, for example, a position sensing system or a live imaging modality to register the patient to the template. The system makes optional use of devices designed to immobilize or track an organ during therapy.

A SURGICAL ACCESSORY TO BE USED WITHIN THE BODY WHICH IS ATTACHED TO THE ABDOMINAL WALL, FOR HOLDING AND POSITIONING TISSUE AND SURGICAL IMPLEMENTS DURING LAPEROSCOPIC OR ROBOTIC SURGERY. THIS CONSIST OF A COLLAPSABLE TABLE WITH ATTACHED FLEXABLE OR FIXED ARMS WITH ACCESSORIES FOR HOLDING SURGICAL TOOLS OR MANIPULATING TISSUES OR ORGANS. A SURGICAL CLIP THAT ATTACHES TO OTHER INSTRUMENTS OFFERING MULTIPLE APPLICATIONS FOR CAPTURING AND SECURING OTHER ACCESSORIES SUCH AS CAMERAS OR INTRA OPERATIVE ULTRASOUND PROBES.

A device is described for marking a path on a skin surface for inserting an epidural needle into an epidural space. The device includes a first arm having one or more holes spaced apart along the length of the first arm. A pin is attached at the proximal end of the first arm. A second arm has a proximal end attached to the pin allowing the first and second arms to rotate about the pin to adjust an angle separating the first and second arms. The second arm has one or more holes spaced apart along the length of the second arm. The holes on the first and second arms provide locations for marking the path on the skin surface to insert the epidural needle.
