Abstract: Provided herein is an accessory for use with a catheter of a blood pump system and a method of use. The accessory may include a first end attached to a repositioning unit of a blood pump and a second end. The accessory is configured to move when a force is applied while the catheter of the blood pump system does not move. The method may comprise applying a force to an accessory to a blood pump system and then moving the accessory in a first direction while the blood pump system does not move in the first direction.

Abstract: A puncture-resistant catheter and/or a puncture-resistant sleeve for a catheter may be provided. The puncture-resistant catheter may have a catheter portion and a puncture-resistant portion. The puncture-resistant portion may be made of a material which is resistant to needles and/or sharp objects. The puncture-resistant portion may be a layer on the outside of the catheter or may be a sleeve attachable to a repositioning unit.

Abstract: Resorbable and/or dissolvable atraumatic tips and methods of using atraumatic tips are provided. The atraumatic tip includes a proximal portion and a distal portion. The proximal and/or distal portion may be made of a material configured to be resorbable and/or dissolvable in the blood of a patient. The atraumatic tip may be attachable to a blood pump assembly.

Abstract: Methods and apparatus for assessing the fit of a blood pump are provided. The method includes receiving an anatomical model representing a cardiovascular system of a patient, determining, based on the anatomical model and one or more physical characteristics of a blood pump, a fit assessment of the blood pump within a portion of the cardiovascular system of the patient, and outputting an indication of the fit assessment on a user interface of a computing device.

Abstract: An assembly includes a catheter surrounded by sheath for delivering a medical device into a cardiovascular system of a patient and a catheter fixation device at least partially deployable from the sheath and transitionable between a radially collapsed state and a radially expanded state. When the catheter fixation device is in the radially collapsed state, the catheter is movable through a conduit of a vessel, and when the catheter fixation device is deployed from the sheath and expanded to the radially expanded to be in contact with an inner wall of the vessel, the catheter is fixed relative to the conduit and relative to the cardiovascular system of the patient. A method of delivering and stabilizing a medical device within a cardiovascular system of a patient is also provided.

Abstract: A graft provided with a catheter fixation device for securing a catheter within a cardiovascular system of a patient. The graft having a proximal end, a distal end, and a sidewall defining a conduit having length extending between the proximal end and the distal end. A fixation device integrated into the graft, the fixation device being configured to transition a portion of the conduit from a first diameter, in which a catheter is movable along the length of the conduit, to a second diameter smaller than the first diameter, in which the catheter is fixed within the conduit. A method of delivering and stabilizing a medical device within a cardiovascular system of a patient is also provided.

Abstract: A catheter fixation device for securing a catheter within a cardiovascular system of a patient. The catheter fixation device includes a body formed of biocompatible material arranged to be subcutaneously secured within a patient, the body including a catheter receiving portion defining a cavity, and first and second wings extending from the catheter receiving portion. The first and second wings are moveable relative to one another from an unclamped position, in which a catheter is moveable within the catheter receiving portion, and a clamped position, in which the catheter is fixed within the catheter receiving portion. A method of delivering and stabilizing a medical device within a cardiovascular system of a patient is also provided.

Abstract: A stabilization device for securing a catheter within cardiovascular system of a patient. The stabilization device includes a base defining a skin contacting surface, and a ladder-lock coupled to the base. The ladder-lock includes a pair of rails and one or more rungs extending between the rails, each of the rails being pivotably attached to the base such that the ladder-lock is pivotable from an unlocked position in which the catheter is slidable within the cardiovascular system of the patient and a locked position in which the catheter is fixed relative to the cardiovascular system.

Abstract: A graft system may be provided. The graft system may include a graft, a hemostasis valve operably coupled to a proximal end of the graft, and a clamp disposed around the proximal end of the graft and configured to hold the hemostasis valve in place relative to the graft. The graft may include a woven or knitted fabric. The clamp may be removably, or permanently, attached to the graft. The hemostasis valve may include a slit membrane disposed within a housing. The hemostasis valve may include an introducer sheath coupled to the housing. The housing may include two portions coupled together along two axial seams, each axial seam extending from a proximal end to a distal end of the hemostasis valve. A grommet may be coupled to an end of the graft.

Abstract: Disclosed is a guidewire for use in, e.g., procedures requiring axillary access and enhanced echo echogenicity. The guidewire may include a proximal portion and a distal portion. The distal portion may include a tapered core wire extending from the proximal portion to a distal tip. The distal portion may have surface texturing on at least one surface near a distal end of the distal portion. The guidewire may have, e.g., a 180° J-tip operably coupled to the tapered core wire. At least a portion of the J-tip may have a stiffness less than a stiffness of the tapered core wire. The J-tip may include a metal-filled polymer, such as a tungsten-filled polyurethane. The tapered core wire may have a maximum diameter of 0.6-0.7 mm, and may have a tapered length of 70-120 mm.
