Patent number: 11724070Abstract: A system of medical devices includes a first medical device, a second medical device, an RLC circuit, a processor, and an output device. The first medical device includes an elongate member having a lumen. The second medical device includes a needle advanceable through the lumen. The RLC circuit includes an excitation voltage source, a resistor, a capacitor, an inductor, and an output voltage sensor. The inductor includes a coil that is supported by the first medical device and wound around the lumen. As the needle is advanced through the lumen, an output voltage of the RLC circuit is an indicator of a longitudinal position of the needle with respect to the elongate member.

Patent number: 11712266Abstract: Intravascular delivery system is designed for a safe and efficient access to secondary and tertiary vascular structures, such as the branches of the coronary sinus, to enhance the delivery and deployment of various catheters, such as, for example, pacemaker electrical leads. The over-the-wire system features a straight, or alternatively shaped, micro-catheter distal tip of an inner catheter that seamlessly cooperates with a peel-away reinforced outer catheter. The inner catheter and the peel-away reinforced outer catheter are advanced in their engaged mode of operation towards (or beyond) the target site. Subsequently, the inner and outer catheters are disengaged, and the inner catheter is removed from the outer catheter. A pacemaker lead may be advanced over the wire inside the outer catheter to the target site for deployment. Subsequently, the outer catheter is easily split and may be rapidly removed from the blood vessel.Type: GrantFiled: June 25, 2021Date of Patent: August 1, 2023Assignee: VANTIS VASCULAR, INC.Inventors: Tim A.

Patent number: 11672741Abstract: Uni-molded pacifier includes nipple, stem, shield and typically a handle. The stem includes a round surface, as in classically designed pacifiers, or may be orthodontically shaped, extending proximally and longitudinally into a base which in turn is blended into a shield. Change in the base to stem contact angle lowers the applied force to the stem as compared to traditional pacifier stems and bases. The decrease in applied force to the stem equates to less pressure needed to compress the stem thru sucking activity. The shield, in this uni-molded pacifier, also has an increase in the area and mass of the center surface. This decreases diameter of the posterior mouth of the shield opening to a lumen of the base and stem which has an added benefit to make it more difficult for debris to enter the lumen. If desired there is no posterior mouth.Type: GrantFiled: September 20, 2019Date of Patent: June 13, 2023Inventor: John J. Davis

Patent number: 11633280Abstract: The active introducer sheath systems disclosed herein are expanded by activating a translation mechanism at the handle. The sheath has an inner cylindrical structure of comingled fixed and mobile elongate rods bound together by an attachment line. Activating the translation mechanism causes the mobile rods to move axially with respect to the fixed rods, changing the internal tension in the attachment line. Increased tension draws the fixed and mobile rods closer together, decreasing the diameter of the cylindrical structure. Decreased tension in the attachment line enables the fixed and mobile rods to move apart, increasing the diameter of the cylindrical structure. A prosthetic device, such as a prosthetic heart valve, can be routed through the expanded sheath and to the implantation site. During implantation, the sheath can be contracted back to its original outer diameter, and expanded again for retrieval of the delivery apparatus.Type: GrantFiled: June 25, 2021Date of Patent: April 25, 2023Assignee: EDWARDS LIFESCIENCES CORPORATIONInventors: David Maimon, Liron Tayeb, Eran Goldberg

Patent number: 11627977Abstract: A surgical instrument includes a shaft and a pair of jaw members disposed on the shaft and extending from an at least partially spherical element. The jaw members are moveable in pitch and yaw relative to the center of the sphere in response to actuation forces applied to a proximal drive mechanism of the instrument. The surgical instrument may include a manually operated handle for manual input of actuation forces by a user, or it may be removably mounted to a drive component of a robotic system such that its proximal drive mechanism is operatively engaged with actuators that generate mechanical output that is transferred to the proximal drive mechanism.Type: GrantFiled: September 16, 2021Date of Patent: April 18, 2023Assignee: Asensus Surgical US, Inc.Inventor: Matthew Robert Penny

Patent number: 11628083Abstract: An internal nasal dilator approximates a U-shape having a bight section and two elongated members with end pads. Each member can be custom formed for comfortable and secure placement in the respective nostrils. Insertion is limited when the bight section of the U contacts the bottom of the user's columella. The upper ends of the members transition to widened areas or pads that face outwardly and are shaped and sized to urge the outer wall of their respective nostril outwardly to dilate the nostril to facilitate breathing. The lower portions of the members have inwardly directed projections at a predetermined distance from the bight; these projections overlie the upper ledge of the columella to interfere with or block withdrawal of the dilator unless a sufficient downward force is exerted to enable the projections to slide off and past the ledge of the columella to allow the dilator to be withdrawn.Type: GrantFiled: March 25, 2020Date of Patent: April 18, 2023Assignee: INTERNATIONAL PATENT DEVELOPMENT GROUP, LLCInventor: Gregory A. M. Brown
