D. Purdy has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20230301528
    Abstract: 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.

  • Patent number: 10716921
    Abstract: Disclosed are sheaths that comprise a first sheath member having a first passageway, a first length, and a first proximal end defined by a first valve apparatus configured to seal the first passageway, the first passageway having a first passageway diameter at a location in the first passageway; and a second sheath member coupled to the first sheath member, the second sheath member having a second passageway and a second length, the second passageway having a second passageway diameter at a location in the second passageway; where the first passageway and the second passageway are separate from each other and not co-axial, the first length is different from the second length, and the first and second sheath members are positioned beside each other for a portion of their first and second lengths.

  • Publication number: 20190351197
    Abstract: 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.

  • Patent number: 9968337
    Abstract: Biopsy devices and methods are provided for collecting a sufficiently-sized tissue sample from a region at a known distance by boring into the sample region using simultaneous axial and rotational movement and providing a reduced risk of: over-passing or under-passing the sample sought, injury and trauma to the surrounding tissue area, having to stick the patient more than once, sample contamination, and the user's exposure to sharps.

  • Patent number: 9895217
    Abstract: The technology described herein relates to a stent graft and a method of making the stent wherein the stent comprises interconnected struts and is connected to the graft material by applying at least one band of polymer so as to cover at least a portion of at least some of the struts. A stent supported area is created by the stent's attachment to the graft material and the at least one band of polymer is applied so as to leave the majority of the stent supported area uncovered by the at least one band of polymer.
