Abstract:
An example medical device delivery system is disclosed. The delivery system includes an inflation shaft having a first lumen, a second lumen and a distal end region, the distal end region including an elongated tip. The delivery system also includes a detachment shaft extending along a portion of the inflation shaft. The delivery system also include a delivery shaft having a proximal end region, a distal end region and a lumen extending therein. The delivery system also includes an occlusive member positioned within at least a portion of the lumen of the delivery shaft, wherein the occlusive member is configured to expand and seal the opening of a left atrial appendage. Further, a portion of the elongated tip is removeably engaged with the occlusive member.
Abstract:
A steerable catheter (10) is disclosed, having an elongated, tubular catheter body (14) with at least one deflection member (30) slidably disposed within a lumen (26, 28), secured at a distal end to a tip section (16) and terminating in an interconnect (46) at a proximal end and a handle (12) releasably attached to the proximal end of the catheter body. The handle has at least one sliding member (54) coupled to an actuator (18), such that manipulation of the actuator causes relative longitudinal movement with respect to the handle, wherein the interconnect and the sliding member engage when the handle is attached to the catheter body so that the relative longitudinal movement of the sliding member is transmitted to the deflection member and wherein the interconnect and the sliding member disengage when the handle is released from the catheter body.
Abstract:
The present disclosure relates to electrically controllable surgical tools. In general, surgical devices are provided having an electrically controllable, fingered operating end for use in angiography, endovascular and/or neurological surgery. The finger(s) at the operating end can be made from ionic polymer metal composite (IPMC) material to facilitate control of the finger(s).
Abstract:
The present disclosure relates to the field of delivery systems for precise navigation within and through body passages. Specifically, the present disclosure relates to delivery systems for accurate positioning and release of elements within tortuous, narrow and/or fragile passages. In particular, the present disclosure relates to a delivery system that includes a distal coil with sufficient flexibility to navigate through tortuous body passages, and which allows for controlled stretch when bent.
Abstract:
This disclosure concerns systems and methods for tissue volume reduction and control of the flow of substances through the body. Systems according to the various embodiments of the disclosure include check valves formed from wire coils which are deployable through a tubular lumen, such as the working channel of an endoscope, or a catheter.
Abstract:
A medical device, configured to perform an endovascular therapy, e.g. , thrombectomy, can comprise an elongate manipulation member having a first connection member proximate a distal end of the elongate manipulation member, and an intervention member having a second connection member proximate a proximal end of the intervention member. The second connection member can be connected to the first connection member such that the first connection member can rotate relative to the second connection member.
Abstract:
Implant (e.g., sensory implant) positionable within subject's left heart atrium, for facilitating functional activity thereof, such as sensing or/and measuring physiological conditions or/and parameters. Implant includes: implant body housing physiological parameter sensing or/and measuring means; coupling means for coupling with an implant deployment device; and septum gripper having a flexible gripping sleeve fixedly connected to implant body wall, and selectively shapeable to pass through organ wall septum opening, and for gripping onto organ wall, such that implant body is fixatable or/and stabilizable across organ wall and through septum opening, to facilitate sensing or/and measuring in subject's body organ. Also disclosed are: a system including the implant, a process control unit, and a transcatheter implant deployment device; and an implant for implantation in subject's body organ separated by an organ wall, and configured for inductive coupling with electronic unit located outside subject's body and for interactively communicating with electronic unit.
Abstract:
Delivery systems for liquid embolics and methods of using them are disclosed. The devices generally include a catheter and one or more retention elements to limit migration of the liquid embolic to non-target sites.
Abstract:
