Surgical port features with electrically conductive portions, related devices, and related methods
A surgical port includes a first end, a second end opposite the first end, and a longitudinal axis extending through the first end and the second end. An outer sidewall extends between the first end and the second end. First and second channels extend through the port from the first end to the second end. A first electrically conductive portion extends from the first channel to the outer sidewall, and a second electrically conductive portion extends from the second channel to the outer sidewall. The first electrically conductive portion provides a first electrically conductive path between the first channel and the outer sidewall and the second electrically conductive portion provides a second electrically conductive path the second channel and the outer sidewall. The second electrically conductive path is separate from the first electrically conductive path. Devices and methods relate to surgical ports.
Torque Device Apparatus and Method of Use
A torque device useable in some embodiments in an endovascular procedure. The torque device is connectable to catheter end to provide an interlocked torque-device/catheter that can be mounted to, and slid over, a guidewire as a unit. A spring arm extends from a main body section of the torque device and can be depressed into the main body section so that the spring arm and main body section can be secured in position with respect to each other. In one embodiment, the depressed spring arm and main body section are mountable to an end of a catheter to secure them in position and to the catheter. Alternatively, the torque device can be mounted to a guide wire by depressing the spring arm, and releasing the spring arm can cause torque device to grip the guide wire and allow the operator to turn or move the torque device and gripped guide wire. Some embodiments provide a torque device through which material may be injected into a catheter to which the torque device is connected.
INFUSION CANNULA
Embodiments disclosed herein relate to an infusion cannula for infusion/venting of fluids to/from the eye to control intraocular pressure. The infusion cannula includes a tubular body with a tubular inlet located at a proximal end of the tubular body and a tubular outlet located at a distal end of the tubular body. The tubular outlet is aligned with a first longitudinal axis and configured to extend through a septum of a valved cannula hub. The infusion cannula includes a retention piece extending from or coupled to the tubular body. The retention piece has an annular body surrounding the tubular body at the distal end of the tubular body and configured to be coupled to the valved cannula hub. An inner surface of the annular body has a profile configured to form a snap fit with an overhang formed along an outer surface of the valved cannula hub.
Catheter including slidable push grip
A catheter may include an elongate body extending from a proximal end to a distal end and defining a lumen; a push member mechanically coupled to the proximal end of the elongate body; and a slidable push grip disposed about an outer perimeter of the push member. The slidable push grip is controllably engageable with the push member. When the slidable push grip is in an engaged state with the push member, the slidable push grip transmits an axial force to the push member to enable the push member to transmit the axial force to the elongate body. When the slidable push grip is in a disengaged state with the push member, the slidable push grip is movable axially in at least one direction along a length of the push member while transmitting substantially no axial force to the push member.
Vascular Access Device to Dispense Blood for Point-Of-Care Testing
An instrument advancement device may include a housing, which may include a distal end and a proximal end. An instrument, such as a vascular access instrument configured to enter vasculature of a patient, may be disposed within the housing. The instrument advancement device may include an advancement element. In response to movement of the advancement element with respect to the housing, the instrument may be configured to advance distal to the distal end of the housing. The housing or a distal end of the housing may include a compressible portion proximate a chamber configured to hold blood. In response to compression of the compressible portion, the housing may be configured to dispense blood distally from the chamber through the distal end of the housing.
Systems and methods for facilitating instrument delivery through a peripheral intravenous catheter
A system for facilitating instrument delivery through a peripheral intravenous catheter may include a catheter adapter having a proximal end, a distal end, and a lumen extending there through. The catheter adapter may include a side port. The system may include an extension tube extending from the side port. The system may include a blood control valve disposed in the lumen of the catheter adapter. The system may include a peripheral intravenous catheter extending distally from the catheter adapter.
SURGICAL PORT
A trocar including a trocar head attached to a cannula having a lumen with a distal opening, the cannula includes at least one elastomeric band positioned across said lumen.
SYSTEMS AND METHODS FOR FACILITATING INSTRUMENT DELIVERY THROUGH A PERIPHERAL INTRAVENOUS CATHETER
A system for facilitating instrument delivery through a peripheral intravenous catheter may include a catheter adapter having a proximal end, a distal end, and a lumen extending there through. The catheter adapter may include a side port. The system may include an extension tube extending from the side port. The system may include a blood control valve disposed in the lumen of the catheter adapter. The system may include a peripheral intravenous catheter extending distally from the catheter adapter.
SURGICAL ACCESS DEVICE HAVING A HOLLOW ANCHOR
A surgical access device has a housing and a tubular member extending from the housing. A collar includes proximal and distal walls along with first and second sidewalls. The first and second sidewalls have a circular configuration and join the proximal and distal walls. The collar is repositionable along a length of the tubular member. A cavity is defined between the proximal and distal walls and the first and second sidewalls. The cavity is configured to store a quantity of a fluid therein. Pores extend through the distal wall and each pore is configured to allow a predetermined quantity of the fluid to flow therethrough. A port is disposed through the proximal wall and is in fluid communication with the cavity. The port is configured to allow the fluid to be introduced into the cavity.
FLOATING HEMOSTASIS VALVE
Disclosed herein is a system for treatment including a sheath introducer and a catheter or other device. The system can have a floating hemostasis valve comprising a seal through which the shaft of the catheter can extend. The floating hemostasis valve can have elastic bellows which can allow the seal to move orthogonal to the longitudinal axis of the sheath introducer in response to an orthogonal movement of the shaft of the catheter. The elastic bellows can be configured to deform to allow the orthogonal movement of the floating hemostasis valve.
