Systems and methods employing a sling delivery assembly having a sling delivery device couplable to a sling assembly to deliver an implant through a transobturator incision point are disclosed. Successful coupling between the sling delivery device and the sling assembly can be verified through changes in an optical or electrical signal produced at the coupling location.

The invention, in various embodiments, provides systems, devices, and methods for treating urinary incontinence.

Hypothermia significantly improves the rate of recovery of function following abdominal surgery—particularly radical prostatectomy. Prior to commencing surgery the tissues at and surrounding the site of the surgery are cooled by means of an endorectal cooling balloon inserted into the patient's rectum. The uninflated balloon is inserted and then inflated with cooling fluid which fluid is constantly circulated in and out to lower the temperature. Improved hypothermia can be achieved by bathing internal tissue with chilled water or buffer. Limitation of surgically induced damage can be demonstrated by the more rapid regain of continence in radical prostatectomy patients treated with hypothermia during surgery.

The present invention relates to hydrogels based on hyaluronic acid based derivatives, that are more resistant than hyaluronic acid alone towards chemical and enzymatic degradation and are endowed with a mix of chemical and mechanical properties such that they are of optimal use in several surgeries, for instance for injection in bone fractures or cavities and for the production of coatings of prostheses in orthopedic surgery, as fillers in cosmetic and maxillo-facial surgery, as anti-adhesion barrier in the prevention of postoperative adhesions in abdominal and abdominal / pelvic surgery, and in general surgery. These hydrogels can be loaded with several different kinds of compounds having pharmacological and biological activity, that are then released from the hydrogel in the site of intervention.

The invention relates to a multifunctional bionic pelvic operation retractor. The multifunctional bionic pelvic operation retractor is mainly composed of a pulling and bracing plate and a locating rod which are connected through a joint rotating shaft, wherein the pulling and bracing plate is of a curved surface structure, the middle of the curved surface is concaved inwards in the direction of the locating rod, the lower end of the pulling and bracing plate horizontally extends outwards, and the end of the pulling and bracing plate is provided with a membrane unfolding hook. According to the multifunctional bionic pelvic operation retractor, by means of the human arm imitation design and integration with an existing cold light source and wireless videoing technologies, a retractor device special for pelvic open operations is developed, multiple hard problems in pelvic operations can be solved simultaneously, an operative field is fully exposed, good lighting is achieved, and meanwhile smoke is sucked and removed, and the function of synchronous videoing is achieved. By means of the multifunctional bionic pelvic operation retractor, the difficulty of the pelvic operations can be reduced, the operating accuracy can be improved, and postoperative complications are reduced.

The invention discloses a pelvic surgery multifunctional retractor which comprises a plurality of retractor bodies. Hooks of the retractors are fixed to first supporting blocks in a leftward and rightward movable mode through first motors. The first supporting blocks are fixed to second supporting blocks in a forward and backward movable mode through second motors. Cylinder bodies of first cylinders of the retractor bodies are fixed to rotating plates. Telescopic rods of the first cylinders are hinged to the left ends of the second supporting blocks. Cylinder bodies of second cylinders are hinged to the telescopic rods of the first cylinders. Telescopic rods of the second cylinders are hinged to the right ends of the second supporting blocks. Third motors are arranged on the rotating plates and fixed to fixed plates. Third cylinders are hinged to the front ends of the fixed plates. Supporting columns are hinged to the rear ends of the fixed plates. The first motors, the second motors,the third motors, the first cylinders, the second cylinders and the third cylinders are all connected with a controller. The movements in three directions and the rotation in three directions of the hooks can be controlled, and it can be ensured that an incision is opened in different directions and angles in the surgery process and different opening degrees and opening states are presented.

To perform pelvic surgery, a directionally illuminating balloon catheter enters a bladder. The catheter has a multi-lumen shaft. The balloon defines an interior fluidically connected to a balloon inflation lumen and is inflated therethrough. The balloon comprises a light source, a light-radiating surface adjacent the shaft-balloon junction, and a substantially opaque surface disposed at a portion of the balloon other than the light-radiating surface such that the integrated light source illuminates a distal half of the environment outside the balloon. The balloon is inflated while in the bladder. Light from the light source is directed out through the light-radiating surface to illuminate at least a portion of a procedure area opposite the bladder-prostate junction. With the light illuminating the portion of the procedure area, at least a portion of a pelvic surgery is performed at the portion of the procedure area.

A male or female human pelvis model including a pelvis for teaching, performing or evaluating skills in physical examinations, medical or surgical techniques or procedures is disclosed. The pelvic model may include replaceable pelvic skeletons and normal, diseased or other modules that provide 3D anatomical representations of various body parts such as skin, organs, muscles, blood vessels, connective tissue, ligaments, tendons or nerves. The pelvis model can include sections that can hold pressurized fluid to mimic body organs, cavities, or blood vessels that hold fluid so that leaks can occur, such as when inadvertently severed or punctured. The rotated top open pelvic region structure may allow for viewing or video capture during simulated surgery.

A urological drape is provided defining a vaginal aperture and a finger cot for accessing the rectum of a patient without making contact therewith. The drape includes an adhesive backing for fixing the drape relative to the patient. Preferably, a pouch is provided which is constructed and arranged to catch any fluids which might be discharged from the vagina during an examination or surgical procedure.
