Patent number: 11672945Abstract: A urinary catheter is readily removed and replaced with a second urinary catheter without introducing foreign matter or contaminants into the bladder. The first urinary catheter includes an extra lumen that houses a sheath therein to seal an opening or third hole at or near the tip of the catheter so that fluids do not enter the extra lumen. After the sheath seal is broken and the sheath is extracted from the catheter, a guidewire is threaded through the extra lumen and into the patient's bladder. The first urinary catheter is withdrawn from the patient, leaving the guidewire in the patient. A second urinary catheter is inserted into the patient over the guidewire, with the guidewire present in the urine lumen of the second urinary catheter. The guidewire then is extracted from the patient.Type: GrantFiled: September 13, 2021Date of Patent: June 13, 2023Inventors: Delbert Kwan, Bruce Aldred

Patent number: 11617397Abstract: A wearable article includes a front and back elastic belts, a crotch region, a waist opening, and leg openings. Each elastic belt is a laminate having an inner sheet, an outer sheet, and an elastic member. Elastic adhesive bonding continuously bonds the elastic member for at least about 10 mm in the direction of stretch adjacent the side edges of the belts. A discrete patterned adhesive bonding is applied to at least one of the inner and outer sheets to intermittently bond the inner and outer sheets. The discrete patterned adhesive bonding extends substantially along the transverse direction between the elastic adhesive bonding, and substantially along the longitudinal direction between the distal and proximal edges of the elastic belts. The same adhesive agent provides the elastic adhesive and discrete patterned adhesive bonding. Heat bonds form side seams, and the remainder of the laminate is free of heat bonds.Type: GrantFiled: February 14, 2020Date of Patent: April 4, 2023Assignee: The Procter & Gamble CompanyInventors: Shiqiao Li, Ruizhi Pei, Kaoru Ishihara, Koichi Morimoto, Xuechun Wang, Ling Tong, John Andrew Strasemeier, Vanessa Marie Melendez, Monica Renee Tournoux

Patent number: 11564846Abstract: In some embodiments, a negative pressure apparatus includes a negative pressure source configured to provide negative pressure via a fluid flow path to a wound dressing placed to create a seal over a wound, a pressure sensor, and a controller. The controller can be configured to operate the negative pressure source in a first mode and determine a change in pressure in the fluid flow path over a period of time based on a plurality of measurements by the pressure sensor. In response to a determination that pressure in the fluid flow path is decreasing, the controller can operate the negative pressure source in a second mode in which greater amount of negative pressure is provided than in the first mode. In response to a determination that pressure in the fluid flow path is not decreasing, the controller can provide an indication of a first leak in the seal.Type: GrantFiled: October 19, 2021Date of Patent: January 31, 2023Assignee: Smith & Nephew PLCInventor: Ben Alan Askem
