Patent number: 5263473Abstract: Disclosed is a compression device and method for applying compressive pressure against a patient's limb in periodic compression cycles, wherein an elongated sleeve having a plurality of inflatable chambers is placed over the foot and a portion of the leg, the chambers being sequentially inflated starting with the foot and then form a distal portion of the leg toward a proximal portion of the leg relative to the heart until all of the chambers are inflated.Type: GrantFiled: January 14, 1992Date of Patent: November 23, 1993Assignee: The Kendall CompanyInventor: Daniel M. McWhorter
-
Patent number: 5117812Abstract: A compression device having a plurality of individual segments separated from each other, each segment having a compression chamber for applying pressure to selected positions of the foot and leg of a patient, a means for intermittently inflating and deflating the compression chamber, a means for releasably securing the segments about a patients limb, and a means for releasably connecting the segments to the inflating means to facilitate rapid connections in time of emergencies.Type: GrantFiled: November 5, 1990Date of Patent: June 2, 1992Assignee: The Kendall CompanyInventor: Daniel M. McWhorter

Patent number: 4815477Abstract: A urine meter attached to a flexible urine collection bag. The urine meter comprises a rigid container which is dischargeable into the collection bag. A valve is disposed at the bottom of the rigid container to permit small samples to be taken in a sterile, multiple use, manner. The valve also permits large urine samples to be taken from the container, by the release of a bias device on the valve. The large samples are taken infrequently. The small samples are taken from a reusable sampling port which reseals itself when the sampling device, such as a hypodermic needle, is withdrawn.Type: GrantFiled: October 15, 1986Date of Patent: March 28, 1989Assignee: The Kendall CompanyInventors: Daniel M. McWhorter, James R. Gross, Carl J. Steigerwald

Patent number: 4200112Abstract: A device for measuring a urine discharge comprising, a hollow receptacle having an inlet port adjacent an upper end of the receptacle to receive the urine discharge and a channel below the inlet port to receive the liquid passing through the port. The device measures the force of the discharge intermediate the port and channel.Type: GrantFiled: July 12, 1978Date of Patent: April 29, 1980Assignee: The Kendall CompanyInventor: Daniel M. McWhorter

Patent number: 4188954Abstract: A catheter comprising, an elongated shaft having a main lumen and an inflation lumen extending along a wall of the shaft. The catheter has a balloon assembly in which an expansible sleeve is joined at spaced zones to an underlying sleeve or tube of a material providing compatible bonding characteristics with the sleeve to facilitate attachment of the balloon onto the shaft.Type: GrantFiled: October 19, 1978Date of Patent: February 19, 1980Assignee: The Kendall CompanyInventors: Bhupendra C. Patel, William J. Binard, Daniel M. McWhorter

Patent number: 4106509Abstract: A drainage system including a balloon catheter comprising a tubular shaft having proximal and distal ends, an inflatable sleeve surrounding the shaft adjacent the distal end thereof and upon inflation retaining the catheter in position by formation of an enlarged balloon surrounding the shaft, a first opening adjacent the distal end of the shaft through which body fluids may pass into a drainage channel which extends from the first opening through the length of the shaft, and a second opening spaced from the first opening through which the fluids may pass from the channel. A longitudinally extending portion of the channel is formed from a porous material which is pervious to air and impervious to body fluids and which is not-wettable by body fluids, and the inflatable sleeve comprises an elastomeric material other than the porous material.Type: GrantFiled: August 5, 1976Date of Patent: August 15, 1978Assignee: The Kendall CompanyInventor: Daniel M. McWhorter

Patent number: 4044757Abstract: A device for use in cholangiography and similar procedures comprising, a first syringe having a barrel defining a chamber for retaining an irrigation liquid, and a plunger having one end received in the chamber for pumping the liquid from the chamber. The device has a second syringe having a barrel defining a chamber for retaining a liquid contrast medium, and a plunger having one end received in the chamber of the second syringe for pumping the contrast medium from the chamber. The device has a catheter having a distal end, a proximal end, and a lumen extending through the catheter. The device also has means for connecting the proximal end of the catheter to the chambers of the first and second syringes without exposing the liquids to the atmosphere intermediate the lumen and chambers, in order that the irrigation liquid and contrast medium may be ejected through the catheter without introduction of air into the device.Type: GrantFiled: January 14, 1976Date of Patent: August 30, 1977Assignee: The Kendall CompanyInventors: Daniel M. McWhorter, Bhupendra C. Patel

Patent number: 4015605Abstract: A drainage receptacle comprising, a collection bag having a back wall and a front wall at least partially defining a chamber in the bag, with the front wall being movable toward and away from the back wall and having an opening communicating with the chamber. The receptacle has a connector attached to the front wall and having a cavity communicating with the chamber through the opening. The receptacle also has a drainage conduit communicating with the connector cavity through an inlet port spaced from the chamber for passage of liquid from the conduit through the opening into the chamber and collection therein. The receptacle also has a sampler conduit communicating with the connector cavity through an outlet port, in order that the connector may be pressed toward the back wall to impede passage of liquid from the drainage conduit into the chamber until the liquid passes through the sampler conduit for obtaining a sample.Type: GrantFiled: October 28, 1975Date of Patent: April 5, 1977Assignee: The Kendall CompanyInventor: Daniel M. McWhorter
