A stent graft delivery system includes a stent graft and a thermal stent graft cutter for shortening the stent graft to a desired length in vivo. The thermal stent graft cutter is coupled to at least one of a stent graft cover at a distal longitudinal end of a cover body thereof, and the inner lumen tip of an inner lumen. A safety system allows activation of the stent graft cutter only when the stent graft is suitably sandwiched between the inner lumen tip and the distal end of the stent graft cover to inhibit inadvertent activation of the cutter and provide for proper cutting of the stent graft.

Systems and methods for selective auto-retroperfusion along with regional mild hypothermia. In at least one embodiment of a system for providing a retroperfusion therapy to a venous vessel of the present disclosure, the system comprises a catheter for controlling blood perfusion pressure, the catheter comprising a body having a proximal open end, a distal end, a lumen extending between the proximal open end and the distal end, and a plurality of orifices disposed thereon, each of the orifices in fluid communication with the lumen, and at least one expandable balloon, each of the at least one expandable balloons coupled with the body, having an interior that is in fluid communication with the lumen, and adapted to move between an expanded configuration and a deflated configuration, and a flow unit for regulating the flow and pressure of a bodily fluid, and a regional hypothermia system operably coupled to the catheter, the regional hypothermia system operable to reduce and/or regulate a temperature of the bodily fluid flowing therethrough.

The present invention relates to a perfusion cannula for placement of an access, having a cannula wall and a perfusion lumen which is surrounded by the cannula wall and in which a fluid flow can flow through the perfusion cannula, wherein the perfusion cannula furthermore comprises at least one sensor lumen and at least one sensor device, in particular an ECG sensor, which is arranged at least partially in the sensor lumen. As a result, it is possible to provide a particularly reliable perfusion cannula with improved functionality and for reliable handling, in particular in conjunction with an extracorporeal lung support system.

A catheter for measuring a fractional flow reserve includes a proximal shaft, a distal shaft coupled to a distal portion of the proximal shaft, and a pressure sensor coupled to the distal shaft. The proximal shaft includes a distal portion configured to extend through a stenosis in a vessel. The distal portion of the proximal shaft includes a radially expanded configuration having a first diameter and a radially collapsed configuration having a second diameter, wherein the first diameter is larger than the second diameter. The distal shaft includes a guidewire lumen configured to receive therein.

In examples described herein, a catheter configured to deliver dialysate and extract an effluent fluid from a peritoneal cavity of a patient includes at least two sensors configured and positioned to generate respective signals indicative of one or more parameters related to PD treatment provided to the patient. The sensors can include, for example, a pressure sensor configured to generate a pressure signal indicative of a pressure of a fluid within a lumen of the catheter or external to the catheter and an impedance sensor configured to generate an impedance signal indicative of an impedance of a fluid within the lumen of the catheter or external to the catheter. A parameter related to PD treatment can include, for example, a catheter status or a peritoneal cavity status of the patient.

This invention is a continuous monitor of the spinal cord and brain microenvironment in injury and disease that also allows therapeutic interventions. It utilizes a multiport catheter that contains a transducer at the tip for monitoring spinal physiological parameters and also allows via additional ports for sampling and exchange of spinal fluid, as well as drug delivery to the central nervous system. This invention allows for more precise therapeutic interventions in spinal cord and brain injury and disease. If the pressure monitor is mounted to the patient, the wireless data transmitter may also send a wireless signal to a wireless data receiver for display on a wireless data display. The catheter would allow for wireless transmission of physiological parameters.

A wound drainage and hemostasis promoting medical device (1) are disclosed. A balloon (15) is temporary inflated and arranged outside a sheath (10), in contact with tissue surrounding a wound cavity for hemostasis promotion. The drainage device comprises a fluid communication channel for wound exudate from wound. The balloon is deflated and retracted into said sheath for removal from said wound cavity. Thus the medical device is percutaneously retractable from said confined wound.

A contact detection instrument 1 is provided with a rod 12, a tip sensor portion 20 that is attached to one end of the rod 12 and is inserted into a living body through a hole, a speaker 14 that, from outside the living body, inputs a sound into a hollow space that is formed in the interior of the rod 12 and the tip sensor portion 20, and a microphone 15 that, outside the living body, outputs an electrical signal that corresponds to the sound inside the hollow space, with the tip sensor portion 20 including an elastic material that covers the hollow space.

Devices, systems, and methods for auto-retroperfusion of the cerebral venous system. In an exemplary embodiment of a catheter for controlling blood perfusion pressure of the present disclosure, the catheter comprises a body having a proximal open end, a distal end, a lumen extending between the proximal open end and the distal end, and a plurality of orifices disposed thereon, each of the orifices in fluid communication with the lumen, at least one expandable balloon, each of the at least one expandable balloons coupled with the body, having an interior that is in fluid communication with the lumen and adapted to move between an expanded configuration and a deflated configuration, and at least one sensor coupled with the distal end of the body, each of the at least one sensors adapted to gather data relating to a fluid flowing through the lumen, wherein the catheter is configured to be coupled to a flow unit for regulating the flow and pressure of a fluid.

The disclosure relates to a catheter, comprising: an elongated shaft body extending along a longitudinal axis and having a distal end portion connected to a catheter tip at a distal end of the catheter, wherein the shaft body comprises a first lumen extending along the longitudinal axis, and an optical fiber for measuring a force, wherein the optical fiber extends in the first lumen and comprises at least a first Bragg grating arranged in in the distal end portion of the shaft body. The distal end portion of the shaft body encloses at least a first stiffening element, wherein the first stiffening element extends along the longitudinal axis for stiffening the distal end portion of the shaft body.
