  • Publication number: 20240325620
    Abstract: A fat harvesting systems and related methods of harvesting and reinjecting fat that provides a medical professional with multiple technique options. Harvested fat can be subjected to a variety of pre-reinjection preparation steps within a single, self contained reservoir such that the potential for contaminating the harvested fat is avoided. The fat harvesting system can be completely self-contained kit requiring no additional external systems or alternatively, can utilize available surgical suite systems, for example, vacuum to successfully harvest, prepare and reinject fat cells. The fat harvesting system can size harvested fat cells so as to be especially desirable for different injection locations in the body. The fat harvesting system is a single use, disposable system that requires no sterilization equipment and recovered and sized fat cells are maintained in a sanitary environment so as to avoid contamination that could result in having to discard recovered fat cells.

    Abstract: A system includes an endoscope connector and an endoscope adapter. The endoscope connector includes a first portion. The first portion includes a first magnetic coupling element and a first planar portion that is perpendicular to an axial direction of the endoscope connector. The endoscope adapter includes a second planar portion. The second planar portion includes a second magnetic coupling element and a substantially planar surface that is perpendicular to an axial direction of the endoscope adapter. The endoscope connector is non-mechanically attachable to the endoscope adapter using the first magnetic coupling element and the second magnetic coupling element. The first planar portion is alignable with the second planar portion such that: electroconductive contacts of the endoscope connector are axially aligned with electroconductive pins of the endoscope adapter and a port of the endoscope connector is axially aligned with a corresponding insertion port of the endoscope adapter.

  • Publication number: 20230404596
    Abstract: A delivery/deployment system having a control handle configured to control delivery and/or deployment of a medical device with arms configured to grasp tissue therebetween. The system may include a device spreader with arms engaging the medical device arms and controlled by an actuator operably coupled with the control handle. The control handle may include a lever pivotable to similarly pivot the device spreader and medical device arms open or closed. A device retention assembly may be provided to retain the medical device with respect to the device spreader. The control handle may include a release element movable to shift the retention assembly into a disengaged configuration allowing release of the medical device from the device spreader. The control handle may axially translate and/or rotate the device spreader into a desired position, and may be fixable in position by a handle lock once in a desired position.

  • Publication number: 20230404565
    Abstract: A delivery and deployment system having a control handle operable to deliver and/or deploy an implantable device, e.g., transluminally. A steering control system may include a steering control knob rotatable about the longitudinal axis of the handle to axially pull on a steering element to steer a flexible elongate member to deliver an implantable device to a desired site. An implantable device deployment system may include a slider selectively slidable with respect to the control handle to deploy an implantable device, and optionally to retain the implantable device in a delivery position. A tether adjustment system may include a knob rotatable about the handle's longitudinal axis to axially pull on a tether element to adjust the tension and/or length thereof. A tensioning and locking system may include a knob rotatable about the handle's longitudinal axis to shift a tensioning and locking device to set the tether element's tension and/or length.

  • Patent number: 11517714
    Abstract: The present disclosure provides a medical device comprising an actuator restraining assembly configured to assist in restraining a catheter shaft in a deflected configuration. The actuator restraining assembly may include a brake element, a release element, a connecting sheath, and a connecting rod disposed in a catheter handle, wherein the connecting sheath and connecting rod are attached to an actuator mechanism, and wherein the at brake element is attached to the connecting sheath and the release element is attached to the connecting rod. The brake element is sized and configured to contact an inner wall of the handle to thereby provide resistance to movement of actuator mechanism in a proximal direction with respect to the handle. In one embodiment, the actuator restraining assembly is configured to allow for temporary, i.e., reversible, restraining of the catheter shaft in the deflected configuration.

  • Patent number: 11478264
    Abstract: The teachings herein provide an instrument comprising a forceps. The forceps comprise a hand piece; a tubular member connected to the hand piece; and a jaw assembly connected to the hand piece. The jaw assembly includes a first jaw element and a second jaw element. The first jaw element includes a gripping section and a flexing section. The flexing section includes an arcuate section. The second jaw element opposes the first jaw element and includes a gripping section. The tubular member is moveable onto the arcuate section of the first jaw element so that the flexing section of the first jaw element is flexed and the jaw assembly is moved into a closed position. The first jaw element, the second jaw element, or both include a stiffening spine so that the jaw assembly is substantially rigid in the closed position.
