  • Patent number: 11844948
    Abstract: Provided is an accurate, fast and long-term stable fused CRAP. The electrode includes a positioning anchor, a silicone catheter, a sensor compartment and a connecting wire. The method monitors physiological information such as blood PPG, blood oxygen saturation, temperature and impedance of blood in the right ventricular cavity, and monitors blood temperature information, which is also a slowly changing metabolic rate, to provide cross-comparison with blood oxygen saturation information, improving monitoring accuracy of blood oxygen saturation. The rapidly changing right ventricular apical impedance information is monitored to improve rapid response ability of CRAP. The LEDs driving current is dynamically adjusted by monitoring the internal temperature of the PPG sensor and the impedance change of the attached biological tissue, which indirectly reflects thickness change of the attached biological tissue, thereby delaying the failure time of the PPG sensor.

  • Patent number: 11826520
    Abstract: The objectives for the designs presented herein can be for a variably flexible and kink-resistant catheter for vascular applications. The designs benefit from good compressive and tensile stiffness. A braided wire support structure can be disposed around an inner liner and an outer layer having a plurality of outer jackets of variable durometer. A metallic reinforcing layer can be cut from a hypotube and be used as the primary structure for catheter stiffness, reducing the reliance on and number of jackets to transition stiffness changes along the length of the catheter. The metallic reinforcing layer can have one or more ribbon cut segments and one or more axial hole patterns laser cut into the hypotube to progressively evolve the stiffness from proximally regions with more column stiffness and distal regions with greater lateral flexibility. The polymer jackets can be reflowed to bond the structure together.

  • Patent number: 11819631
    Abstract: Systems, devices, and methods for detaching an implantable device from a delivery system are disclosed herein. One aspect of the present technology, for example, is directed toward an elongated shaft having an inner surface that defines a lumen that extends distally from the proximal portion to an opening at a distal terminus of a distal portion. In some embodiments the distal portion includes an inner polymer structure having a first portion and a second portion positioned distal of the first portion along the length of the inner polymer structure. The first portion can have a first stiffness and the second portion can have a second stiffness less than the first stiffness. The distal portion can further include an outer polymer structure disposed around the inner polymer structure and a coil wound around the inner polymer structure and disposed within the outer polymer structure.

  • Patent number: 11819227
    Abstract: Provided are a treatment method, a separation method, and a filter assembly capable of preventing so-called “Blue Toe syndrome” which is so-called cholesterol crystal embolism of which a fat-soluble compound such as cholesterol crystals generated during dilation of a stenosed site causes clogging in glomeruli of peripheral capillaries or kidney, acute renal failure, and the like. Cholesterol crystals generated from plaque during use of a balloon catheter are taken out of the body and removed using a centrifugal separation device or a filter, and usable living cells are returned to the body to reduce blood transfusion and reduce cholesterol crystal embolism.

  • Patent number: 11813038
    Abstract: Techniques for remotely titrating a therapy delivered using an implantable medical device system are disclosed. An implantable medical device delivers therapy according to a first program. The system collects patient data relating to at least one of an efficacy of, or side effects resulting from, the delivered therapy, and transmits the patient data to a remote network device. A clinician may then analyze the patient data and determine if changes to the therapy are warranted. The clinician may then transmit a programming change, e.g., a modification to the first program or a new, second program, to the implantable medical device system, and the implantable medical device may deliver therapy according to the changed programming. The process of receiving patient data and modifying the therapy programming may be repeated multiple times until the therapy is adequately titrated, e.g., until the patient data indicates adequate efficacy and/or acceptable side effects.

  • Patent number: 11813163
    Abstract: A method for connecting an annuloplasty implant with a delivery and retrieval device includes retracting the annuloplasty implant towards a locking structure of the delivery and retrieval device with a retrieval element. The retrieval element connects the annuloplasty implant with the delivery and retrieval device when the annuloplasty implant is disconnected from the delivery and retrieval device. A complementary mating surface at an end portion of the annuloplasty implant is interlocked with a locking structure of the delivery and retrieval device. The complementary mating surface has a recess for locking longitudinal movement of the annuloplasty implant when it is received in the locking structure. The complementary mating surface has a first locking surface aligned in a first radial direction (R) to lock rotational movement of the annuloplasty implant, when received in the locking structure, around the longitudinal direction.

  • Patent number: 11806488
    Abstract: Shapeable guide wire devices and methods for their manufacture. Guide wire devices include an elongate shaft member having a shapeable distal end section that is formed from a linear pseudoelastic nickel-titanium (Ni—Ti) alloy that has linear pseudoelastic behavior without a phase transformation or onset of stress-induced martensite. Linear pseudoelastic Ni—Ti alloy, which is distinct from non-linear pseudoelastic (i.e., superelastic) Ni—Ti alloy, is highly durable, corrosion resistant, and has high stiffness. The shapeable distal end section is shapeable by a user to facilitate guiding the guide wire through tortuous anatomy. In addition, linear pseudoelastic Ni—Ti alloy is more durable tip material than other shapeable tip materials such as stainless steel.
