Publication number: 20230301528Abstract: A system and method for monitoring the blood pressure of a patient that allows for a device sensor to be recalibrated according to atmospheric pressure without removing the device sensor from inside the patient. This permits quickly monitoring the blood pressure of a patient if a re-zero is needed. The invention has a blood pressure monitor (BPM) that obtains an atmospheric pressure observation. The atmospheric pressure observation is adjusted and stored to memory as a zero value. The zero value is retrieved to recalibrate the system and method if a device sensor has been disconnected from and reconnected to the same or a different BPM, the patient has been moved such that the surroundings have been altered to make it necessary to recalibrate according to atmospheric pressure, and/or the device sensor has been connected to a different patient care monitor.Type: ApplicationFiled: May 26, 2023Publication date: September 28, 2023Inventor: Phillip D. Purdy

Publication number: 20190351197Abstract: A coated medical device (10) including a structure (12) adapted for introduction into a passage or vessel of a patient. The structure is formed of preferably a non-porous base material (14) having a bioactive material layer (18) disposed thereon. The medical device is preferably an implantable stent or balloon (26) of which the bioactive material layer is deposited thereon. The stent can be positioned around the balloon and another layer of the bioactive material posited over the entire structure and extending beyond the ends of the positioned stent. The ends of the balloon extend beyond the ends of the stent and include the bioactive material thereon for delivering the bioactive material to the cells of a vessel wall coming in contact therewith. The balloon further includes a layer of hydrophilic material (58) positioned between the base and bioactive material layers of the balloon.Type: ApplicationFiled: November 13, 2017Publication date: November 21, 2019Applicant: Cook Medical Technologies LLCInventors: Brian L. Bates, Anthony O. Ragheb, Joseph M. Stewart, IV, William J. Bourdeau, Brian D. Choules, James D. Purdy, Neal E. Fearnot
