BI-LATERAL CATHETER SYSTEM AND METHODS FOR USE
The present disclosure provides an apparatus including a first tubular housing including a first exit port and a second tubular housing including a second exit port. The apparatus also includes a third tubular housing coupled to at least one of the first tubular housing and the second tubular housing such that each of the first tubular housing, the second tubular housing, and the third tubular housing are fixed with respect to one another. The apparatus also includes a first catheter including a first plurality of outlets and is configured to be positioned at least partially within the first tubular housing. The apparatus also includes a second catheter including a second plurality of outlets and is configured to be positioned at least partially within the second tubular housing. The apparatus also includes a pressure transducer line positioned in the third tubular housing and a pressure transducer coupled to the pressure transducer line.
DEPTH GAUGE SYSTEM
Disclosed are a puncture sealing system and methods of locating a depth of an arteriotomy. The systems can include elongated catheters that are configured to identify the depth within a vessel so that the depth relative to a distal end of the catheter is known during or after a puncture sealing procedure.
SYSTEM AND METHOD FOR CANNULA FIBER LUMEN STRAIN RELIEF
A system that includes a cannula and a flexible hypotube attached to the cannula configured to slidably receive an optical fiber. The system may be configured to have a ratio R1 of a diameter of the outer surface of the hypotube to a diameter of the inner surface of the cannula is 1:5>R1>1:25, and/or where the flexible hypotube comprises a tubular portion containing at least one cut extending from the outer surface at least partially through the sidewall of the flexible hypotube, each cut having a maximum width of between 0.01 and 0.1 mm.
Methods and systems for treatment of acute ischemic stroke
Methods and devices are disclosed that enable safe, rapid and relatively short and straight access to the cerebral arteries for the introduction of interventional devices to treat acute ischemic stroke. In addition, the disclosed methods and devices provide means to securely close the access site to the cerebral arteries to avoid the potentially devastating consequences of a transcervical hematoma.
IMPLANTABLE CRANIAL MEDICAL DEVICE
An implantable cranial medical device includes a first fluid flow path, a second fluid flow path, and upper flange portion, and a lower portion. The upper flange portion is configured to rest on a skull of a subject about a burr hole. The lower portion is configured to be placed within the burr hole. The first fluid flow path may extend from a first opening in the upper flange portion to a first opening in the lower portion. The second fluid flow path may extend from a second opening in the upper flange portion to a second opening in the lower portion.
Devices, systems and methods for accessing a body lumen
The present disclosure relates to medical devices that that include the following: a flexible elongate tube having a proximal end and a distal end configured to be directed toward an opening of a body lumen; a first lumen extending from the distal end of the tube proximally along the tube and having a fluid connection for a fluid source at its proximal end; a second lumen extending from the distal end of the tube proximally along the tube, the second lumen configured to accept a guidewire extending along the second lumen; and a wire filament extending along the elongate tube, a distal end of the filament connected to the distal end of the elongate tube, a proximal portion of the wire extending at least partially along the elongate tube, and a distal portion of the wire extending external to the elongate tube.
CATHETER ASSEMBLY
A multi lumen catheter assembly. The assembly provides an expandable, low profile, fixed length sheath and catheter, with fixed infusion ports. The assembly has an expandable outer sheath that expands upon pressure activation with a fluid and the sheath allows the fluid to exit from at least one predetermined fixed location from a distal end of the catheter assembly. The catheter assembly can be used in various medical device procedures, such as a TIPS (Transjugular Intrahepatic Portosystemic Shunt) procedure, or anywhere a low profile, multi lumen, infusion catheter system is desired.
DELIVERY OF EMBOLIC BRAID
A method for constructing a braided implant delivery system and treating an aneurysm can include attaching a braided implant having a band attached thereto to a delivery tube, positioning the braided implant within the aneurysm, and releasing the band from the delivery tube, thereby releasing the braided implant. The band can include movable extensions that can press into an outer surface of the delivery tube to secure the band to the delivery tube then move away from the outer surface of the delivery tube to release the band. A pull wire can be engaged to the band to secure the band to the delivery tube then be pulled proximally to release the band from the delivery tube. At least a portion of the braid of the braided implant can be positioned within a lumen of the delivery tube.
Dual-lever bi-directional handle
An improved bi-directional steerable catheter is provided. The catheter generally comprises a catheter body, tip section and control handle. The catheter further comprises first and second puller wires extending from the control handle, through the catheter body and into the tip section. The control handle has deflection means for each puller wire that include a gear, and a carrier to which the proximal end of a puller wire is anchored. The gear is rotatably coupled to a lever controlled by an operator and the gear engages the carrier such that rotation of the gear by the lever results in longitudinal movement of the carrier, which results in deflection of the tip section.
Catheter for treating ectopic pregnancy, catheter guide, and catheter unit for treating ectopic pregnancy, including the catheter and the catheter guide
The present invention relates to a catheter for treating ectopic pregnancy, of which one end is inserted into the fallopian tube through the vaginal cavity, and the other end is exposed to the outside of the body, wherein the catheter comprises: at least one passage portion forming a liquid passage entering through the one end or the other end; a penetrative portion connected to the one end, and including a foremost end for penetrating the gestational sac; and a connecting portion connected to the other end, and capable of being coupled to at least one syringe tool for injecting or suctioning the liquid. Accordingly, side effects from open surgery can be prevented, and excellent treatment effects can be obtained by more safely and quickly treating ectopic pregnancy.
