A laparoscopic flexible suction/irrigation device of the present invention encases a inner rigid cannula with an outer flexible cannula. Upon translating the distal end of outer flexible cannula beyond the distal end of the inner rigid cannula, the outer flexible cannula returns to a preexisting curvilinear shape. This curved extension can thereafter be positioned via a proximal handle to concavities within the surgical site for precise and effective fluid retraction.

The present invention is a decompression needle assembly having a needle that is removable received into to a catheter. The catheter can include a rigid portion and a deformable portion wherein the deformable portion can be multi-ported at its distal end. A one-way valve contained in a catheter hub attached to the catheter wherein the one way valve is in an open position when the needle is received in the catheter. Lateral catheter openings can be defined in the catheter and disposed adjacent to a distal end of the catheter. A plunger can be received within the needle and have an visual and auditory indicator that can be appreciated through the needle hub.

The embodiments presented herein relate to concepts designed to eliminate the gap between a catheter and guide wire that can otherwise contribute to a catheter getting stuck within the vasculature.

A transseptal catheter delivery system includes an elongate first tubular member and an elongate second tubular member receivable within the first tubular member. The first tubular member includes an adjustable portion adjacent a distal end. The second tubular member is adapted to receive an instrument to be placed in the left ventricle, and includes a curved portion adjacent its distal end in a relaxed state. The adjustable portion is deflectable toward the atrial septum to guide a puncturing tool and/or guide insertion of the second tubular member through a septal puncture into the left atrium. Within the left atrium, the curved portion is oriented toward the left ventricle to guide insertion of a guide wire, and subsequently the second tubular member, into the left ventricle. Methods of transvenously accessing a left ventricle are also provided.

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.

The invention is directed to a device in the form of a tube or catheter for draining and/or sealing a natural or artificial bladder outlet, comprising a shaft body that can be applied from extracorporeal into a bladder of the patient, as well as a balloon that surrounds the shaft body like a cuff and is placed in the bladder for the purpose of a vesical anchoring of the shaft body in the bladder, wherein the shaft body, which is produced by means of molding, is having a profile with a wavy corrugation, providing the shaft body with a radial stability and with a kink-free axial bending property.

The present disclosure describes a rolling sleeve having a malleable body. The rolling sleeve is configured to protect an endoluminal shaft from surrounding tissue during insertion, navigation, and/or treatment within a body lumen.

A neurovascular catheter can have an elongate flexible tubular body. The tubular body can have a proximal end, an inclined distal end, and a side wall that defines a central lumen. The neurovascular catheter can further have a distal leading tip on a first side of the inclined distal end. The neurovascular catheter can further have a preset curve in a distal zone of the tubular body such that wherein the distal leading tip lies on a concave side of the curve.

A cannula mounting fixture may include a base, a first arm with a first cannula mounting bracket and a second arm with a second cannula mounting bracket. The first arm may be coupled to the base so that a first cannula mounted at the first mounting bracket is positioned within an opening in a patient's body. The second arm may be coupled to the base and includes a joint that allows a second cannula mounted at the second mounting bracket to be inserted through the opening. A cannula stabilizing fixture may include a base and a repositionable arm. The base may be configured to be securely and removably coupled to a first cannula that extends into an opening in a patient's body. The repositionable arm may include a first cannula holder coupled to the base and is configured to support a second cannula that extends into the opening.

The present disclosure provides for a fluid delivery device for a body vessel and a method of use. The fluid delivery device may have an elongate member having a proximal end extending along the longitudinal axis to a closed distal end. The elongate member may also have an inner wall defining a fluid delivery lumen and a wire guide lumen. The elongate member may have a tapered region and a distal portion between the proximal and distal ends. The device may have a first state for device delivery to the treatment site.
