Publication number: 20240041483Abstract: A method and device for advancing a guidewire past a calcified leaflet of a heart valve are described. A dual guidewire device includes a primary guidewire, a secondary guidewire, and a sheath. The primary guidewire is configured to advance past a heart valve while the secondary guidewire is configured to pull open the calcified leaflet of the heart valve while the primary guidewire advances past the heart valve. The catheter can contain both the primary guidewire and the secondary guidewire.Type: ApplicationFiled: September 12, 2023Publication date: February 8, 2024Inventors: Sakyasingh Tripathy, Hengchu Cao, Nima V.

Publication number: 20240041484Abstract: An extended catheter includes a catheter body, a pushing reinforcement wire, a pushing rod, and a positioning balloon. The catheter body is provided with a delivery channel, and a proximal end of the catheter body is provided with an inlet connected to the delivery channel. The pushing reinforcement wire is arranged on a side wall of the catheter body along an axial direction of the catheter body. A distal end of the pushing rod is connected to the proximal end of the catheter body, and an interior of the pushing rod is provided with a filling channel. The positioning balloon is sleeved on the catheter body, and an inner cavity of the positioning balloon is connected to the filling channel. Problem of existing catheters unable to effectively reach the designated position in curved and narrow branch blood vessels for treatment is solved.Type: ApplicationFiled: October 10, 2023Publication date: February 8, 2024Inventors: Zhijun Zhang, Chaosheng Liu, Guansheng Zhong

Publication number: 20240041486Abstract: A medical device for the treatment and irrigation of a sinus opening is described. The device allows for single-handed operation to access, dilate and irrigate a sinus opening. The device includes a sinus guide catheter, a guiding element, a balloon dilation catheter, a balloon catheter movement mechanism and a guiding element movement mechanism. A method for treating a sinus opening and irrigating a sinus is also described.Type: ApplicationFiled: October 17, 2023Publication date: February 8, 2024Inventors: Mina W. Chow, Thomas R.

Publication number: 20240041487Abstract: An end effector having first and second jaws movable between an open configuration and a closed configuration. At least one jaw has a tissue-engaging surface contoured to enhance grasping of tissue between the jaws. For instance, the tissue-engaging surfaces may be contoured to engage tissue along the tissue-engaging surface substantially evenly/uniformly and/or contemporaneously from the distal end to the proximal end of the jaw. The tissue-engaging surfaces may be contoured independently of and/or differently from the jaw's outer surface. The tissue-engaging surfaces of the first and second jaws may be contoured to enclose tissue engaged therebetween.Type: ApplicationFiled: August 2, 2023Publication date: February 8, 2024Applicant: BOSTON SCIENTIFIC SCIMED, INC.Inventors: Yeison Calvo, Sean P. Fleury, Gian Franco Loo Fuchs

Publication number: 20240041489Abstract: An ultrasonic tool system with a console and a tip that has a distal end that when vibrated vibrates both longitudinally and torsionally. The console applies a drive signal to the drivers that vibrate the tip that is at a longitudinal mechanical cancelation frequency. Consequently, when the tip is vibrated, at the distal end the longitudinal component of a first resonant mode of the tip cancel out the longitudinal component of the second resonant move of the tip so the distal end of the tip engages in vibrations that substantially torsional and only minimally longitudinal.Type: ApplicationFiled: October 17, 2023Publication date: February 8, 2024Applicant: Stryker CorporationInventor: Adam Downey

Publication number: 20240041490Abstract: Apparatus and methods for tissue reduction are described where one embodiment of the tissue resection device may generally comprise an external clamping mechanism having at least two distally extending members shaped with an atraumatic distal end and defining a confined region between the distally extending members sized to receive a tissue region therebetween. Additionally, an elongate coring needle defining a lumen and having a proximal end attached to a handle and a distal end which defines a cutting mechanism may also be included, wherein the coring needle is translatable adjacent and/or relative to the external or internal clamping mechanism defined by the confined region.Type: ApplicationFiled: October 18, 2023Publication date: February 8, 2024Applicant: CorIT Medical, LLCInventors: Iyad SAIDI, Cameron LOPER, Charles M.

Publication number: 20240041491Abstract: An occlusion crossing device that includes an outer shaft having an inner lumen and an inner shaft including a distal end with a drill tip body. There is a projection extending from the inner shaft, in which the inner shaft is removably coupled to the outer shaft so that, in a first configuration, the inner shaft can move axially, and can rotate clockwise or counter-clockwise relative to the inner lumen of the outer shaft, in which, in a second configuration, the projection is configured to engage one or more engagement sites at a distal region of the outer shaft so that the outer shaft and the inner shaft rotate tighter, and further in which in the second configuration, a pulling force on the inner shaft relative to the outer shaft causes the occlusion crossing device to deflect in a first direction, and a pushing force on the inner shaft relative to the outer shaft causes the occlusion crossing device to deflect in a second direction that is opposite the first direction.Type: ApplicationFiled: October 3, 2023Publication date: February 8, 2024Inventor: Himanshu N.
