摘要： Mixing systems for producing a mixture to deliver to a treatment site. An illustrative system may comprise a needle hub, a multi-reservoir system, and a syringe. The multi-reservoir system may comprise a plunger assembly including a first tubular plunger and a second tubular plunger, a barrel portion including a housing defining a first reservoir in fluid communication with a first port and configured to contain a first constituent and a second annular reservoir configured to contain a second constituent and in fluid communication with a second port, and a third plunger. A third constituent may be injected from the syringe into the first reservoir to form a precursor. Actuating the plunger assembly relative to the barrel portion may cause the precursor and the second constituent to be delivered into the needle hub.

摘要： Mixing systems for producing a mixture to deliver to a treatment site. An illustrative system may comprise a needle hub and a multi-reservoir system. The multi-reservoir system may comprise a first plunger assembly, a second plunger assembly, and a barrel portion. The first plunger assembly, the second plunger assembly, and the barrel portion may be assembled in a telescoping arrangement. Advancing the first plunger assembly may cause a first constituent to be delivered from a first reservoir of the second plunger assembly into the third reservoir to mix with a third constituent to form a precursor and a second constituent to be delivered from a second reservoir of the second plunger assembly into the fourth reservoir and advancing the first and second plunger assembly collectively causes the precursor and the second constituent to be delivered into the needle hub.

摘要： A multi-chamber device having a barrel with a first chamber and a second chamber, and a plunger assembly with a first plunger rod advanceable with respect to the first chamber and a second plunger rod advanceable with respect to the second chamber. The ends of the first and second plunger rods are independently advanceable to advance different amounts of material from the first and second chamber as the plunger assembly is advanced with respect to the barrel. The multi-chamber device may be part of a multi-chamber system including an injection system. The multi-chamber device and the injection system may include engaging elements facilitating ready coupling and decoupling of the multi-chamber device and the injection system.

摘要： Devices, systems, and methods for combining and/or delivering an injectable material to a patient. A first device having a first nozzle is moved rotationally and/or generally axially with respect to a second device having a first nozzle port to seat the first nozzle with respect to the first nozzle port. The second device has a nozzle pocket positioned, sized, shaped, configured, and/or dimensioned with respect to the first nozzle port to guide axial and/or rotational relative movements of the first injectable material transfer device and the second injectable material transfer device to guide the first nozzle into alignment with the first nozzle port, such as to be seated with respect to the first nozzle port.

摘要： Devices, systems, and methods for combining and/or delivering an injectable material to a patient. A vial adaptor is configured to fluidly couple at least a first chamber and a separate chamber and to facilitate fluid exchange therebetween as well as to vent the separate chamber as material is withdrawn therefrom. The first chamber may be defined in a multi-chamber device which further defines a second chamber. The vial adaptor further defines a purge reservoir into which excess material and/or air may be purged from the second chamber. For instance, as material is ejected from the first chamber into the separate chamber, a determined amount of material may be purged from the second chamber into the purge reservoir.

摘要： A system for treating tissue includes an applicator including a catheter and a control member extending therethrough, the control member longitudinally movable relative to the catheter and including an abutment structure proximate a distal end thereof, and a clip assembly releasably coupleable to a distal end of the applicator, the clip assembly including a pair of clip arms, a proximal end of each of the clip arms slidably received within a channel of a capsule and configured to be releasably coupled to the distal end of the control member so that the clip arms are movable relative to the capsule between a tissue receiving configuration and a tissue clipping configuration, the capsule including proximal tabs movable between a biased non-engaging and an engaging configuration, in which the proximal tabs engage an engaging portion of the lumen of the catheter, when the abutment structure is received within the capsule.

摘要： Novel and unique medical devices and associated methods are disclosed, for a medical device for puncturing tissue at a tissue site. The medical device includes an elongate member having a distal section defining a distal section curved portion and a distal section straight portion. The distal section straight portion is distal to the distal section curved portion. An active tip is located at a distal end of the distal section. The active tip is operable to deliver energy to create a puncture through the tissue. The medical device includes a constant diameter layer. The distal section straight portion includes a minimum diameter portion located proximal to a constant diameter portion, and the constant diameter layer surrounds the minimum diameter portion.

摘要： A method of puncturing from an aorta into a left atrium using a puncturing device. The method involves a step of accessing a carotid artery and advancing a puncturing device through the carotid artery into an aorta. Advancing a sheath and a dilator over the puncturing device through the carotid artery and into the aorta such that a puncturing tip of the puncturing device is aligned with a distal tip of the sheath and a distal tip of the dilator, forming a puncturing assembly. Positioning the puncturing assembly at a target site within the aorta to gain access to a left atrium of a heart. Tenting a tissue between the aorta and the left atrium using the puncturing assembly. Creating a puncture through the tissue by advancing the puncturing device such that a channel between the aorta and the left atrium is formed.

摘要： A variety of medical procedures utilize two or more medical device components, including medical device components where a first medical device component is advanced within a second medical component. An example would be an elongate dilator used in combination with a guide catheter. The guide catheter and the elongate dilator may be adapted to provide a rotational lock mechanism that allows the guide catheter and the elongate dilator to lock together such that rotating one of the components causes rotation of both components. In some instances, the guide catheter and the elongate dilator may cooperate to also provide a relative axial lock between the two components.
