The egress valve is closed when the interior space is filled with the inflation fluid and is capable of being opened to allow the inflation fluid to vent from the interior space. | 09-04-2014 |
| 20140257042 | Expandable Transluminal Sheath - Disclosed is an expandable transluminal sheath, for introduction into the body while in a first, low cross-sectional area configuration, and subsequent expansion of at least a part of the distal end of the sheath to a second, enlarged cross-sectional configuration. The distal end of the sheath is maintained in the first, low cross-sectional configuration and expanded using a radial dilatation device. In an exemplary application, the sheath is utilized to provide access for a diagnostic or therapeutic procedure such as ureteroscopy or stone removal. | 09-11-2014 |
| 20140303447 | SURGICAL DRAPE SYSTEM FOR UROLOGY PROCEDURES ON FEMALE PATIENTS - The invention is a simple surgical drape system for female urology procedures that provides sealed isolation of top versus bottom sides of the drape and only exposes the female urethral meatus area for the procedure. It is achieved by a combination of a drape with a fenestration, a labia spreader where the drape fenestration is attached to provide a seal, and local illumination of the meatus area integrated in the drape system for safer and easier instrument insertion. The labia spreader also frees up one of the operator's hands and provides protection for false catherization. The labia spreader can have a vaginal inserted portion for precise position fixation of the drape fenestration to the female. The drape system also provides improved liquid management made possible by the unique combination of drape and labia spreader acting as seal between the two sides of the drape. | 10-09-2014 |
| 20150065807 | 4-WAY CYSTOSCOPY CATHETER - Systems and methods of cannulating a body orifice such as a bladder are disclosed. A cystoscopy catheter can include a proximal end, a distal end having at least one exit port, and a flexible elongate tubular body therebetween; an inflatable balloon near the distal end of the catheter, the balloon transformable from an unexpanded and an expanded configuration; a first proximal port for fluid inflow; a second proximal port for fluid outflow; a third proximal port for balloon inflation, in fluid connection with the balloon; and a fourth proximal port for insertion of a diagnostic and/or therapeutic instrument such as a cystoscope therethrough, wherein the first, second, and fourth proximal ports are fluidly connected to a common central lumen extending through the elongate tubular body to the exit port on the distal end. | 03-05-2015 |
| 20150073223 | TROCAR CANNULA ASSEMBLY AND METHOD OF MANUFACTURE - A cannula assembly having a retention member and a method of manufacture of the cannula assembly is provided. The cannula assembly includes a cannula and a sleeve disposed around the cannula from a proximal end to a distal end. The sleeve can be pre-formed by a stretch blow molding process then advanced over the cannula. The sleeve includes an inflatable balloon and an annular ring distal the inflatable balloon. The cannula includes an annular recess. The annular ring is sized to have an interference fit with the annular recess. | 03-12-2015 |
| 20150112147 | ACCESS ASSEMBLY - An access assembly includes a body portion defining a longitudinal axis and having at least one lumen defined therethrough. The at least one lumen is configured for passage of a surgical instrument therethrough. An outer sleeve is disposed about the body portion to define a chamber therebetween. The chamber is selectively inflatable from a deflated condition, for positioning the access assembly within an opening in tissue, and an inflated condition, for retaining the access assembly within the opening in tissue in sealing relation therewith. | 04-23-2015 |
| 20150297210 | SURGICAL BOWEL RETRACTOR DEVICES - Bowel retractor devices. In various forms, the bowel retractor devices are configurable from a collapsed position wherein the retractor may be inserted through a trocar cannula or other opening in a patient's body to a second expanded position wherein at least a portion of the patient's bowel may be advantageously supported in a desired position. | 10-22-2015 |
| 20160135799 | SOFT ROBOTIC RETRACTORS - Exemplary embodiments describe soft robotic actuators for medical use, such as during surgeries and other medical procedures. According to one embodiment, a soft robotic incision retractor is provided. According to another embodiment, a soft robotic body tissue retractor is provided. The incision retractor and body tissue refractor may be used together, for example by using the incision retractor to hold open an incision while the body tissue retractor manipulates biological matter or an object accessible through the incision. Described embodiments offer the ability to conform to a given space, reduced risk of damage to surrounding structures as compared to traditional retractors, the ability to deliver varying amounts of force, the ability to be made from medically safe materials, and the potential for re-use or disposability. | 05-19-2016 |
