Abstract:
A flexible tip dilator (4) is disclosed. The flexible tip dilator includes a hollow elongated tubular member with a proximal region and a tapered distal region. The tapered distal region has three regions with a first region (14) made from at least a first material but not a second material and a third region (16) made from at least the second material but not the first material. The second region (22) includes both the first and second materials overlapping one another.
Abstract:
Delivery devices, systems, and methods for delivering implantable leadless pacing devices are disclosed. An example delivery device may include a proximal section including a deflection mechanism for deflecting the proximal section, and a distal holding section extending distally of a distal end of the proximal section and defining a cavity therein for receiving an implantable leadless pacing device. The distal holding section may be structured to have portions that flex and bend while allowing the implantable device to be recaptured within the distal holding section.
Abstract:
A catheter assembly (10) includes a catheter (12) at least partially positioned within a sleeve (14). The catheter has a coating, which produces a low-friction surface on the catheter when treated with an activating fluid. A protective tip (16) is connected to the proximal end (18) of the sleeve (14) and has proximal (28) and distal (30) internal seals, with the proximal seal (28) at the proximal end (24) of the tip (16) or between proximal (24) and distal (22) ends of the protective tip (16). A cap (32) of the assembly has a projection (34), which is removably received within the protective tip (16) for sealing engagement with the proximal (28) and distal (30) seals to define a fluid reservoir (38) within the protective tip (16). An activating fluid is contained within the fluid reservoir (38). The projection (34) may be partially hollow to receive a portion of the catheter (12). The sleeve (14) may be relatively narrow or at least have a narrowed portion for better distribution of activating fluid to the surface of the catheter.
Abstract:
A catheter with a spring tip that facilitates atraumatic initial placement and also continues to protect tissue contacted by the catheter device subsequent to the initial placement. The spring tip is shock-absorbing and axially compliant and allows enhanced use of various devices in conjunction with the tip such as bioptomes, electrodes, needles, flushing catheters, delivery catheters, and the like. The atraumatic shock-absorbing tip could include conductive or non-conductive materials.
Abstract:
A catheter suitable for deploying a filter element comprising: - A filter retaining member (108, 112); - A guidewire hub (116) connected to a proximal end of the filter retaining member and having a first guidewire lumen (118) for receiving a primary guidewire (120) and a second guidewire lumen (126) for receiving a second guidewire; - A proximal shaft connected to a proximal end of the guidewire hub; - An activating member (140) coupled between the filter retaining member and the proximal shaft for controllably releasing the filtering element into the selected vasculature.
Abstract:
A delivery tip extension communicates an adhesives material from a fluid applicator tip to a site within a patient. The delivery tip extension has an elongated shaft with a proximal end portion, a central body portion, and a tapered distal end portion. The central body portion has a length between about 5 cm and about 45 cm. A lumen is defined within and extends along the elongated shaft from a proximal opening to a distal opening. The elongated shaft is relatively more rigid along the central body portion than along the distal end portion to facilitate driving the elongated shaft through the patient with reduced trauma to the patient by the distal end portion. The lumen is sized and shaped along the proximal end portion for securely receiving the fluid applicator tip inserted through the proximal opening such that a dispensing outlet on the fluid applicator tip is in fluid communication with the lumen. The delivery tip extension is sterilized or sterilizable.
Abstract:
Canule (5) pour un dispositif d'anesthésie laryngo-trachéale (1 ) comportant un tube (6) allongé semi-rigide comprenant une extrémité proximale (14) destinée à être raccordée à une seringue (2) contenant le liquide anesthésique et une extrémité distale (15) destinée à être insérée dans la cavité laryngée jusque dans la trachée d'un patient, plusieurs orifices de sortie (16) de liquide anesthésique étant prévus à partir de l'extrémité distale (15) sur une zone prédéterminée de la longueur dudit tube (6). Selon l'invention, ledit tube (6) est incurvé sur toute sa longueur comprise entre ladite extrémité proximale (14) et ladite extrémité distale (15) et ledit tube (6) est ouvert à son extrémité distale (15) et permet de recevoir un ensemble formant embout souple (9) comportant une sortie axiale (33) de liquide anesthésique.
Abstract:
A catheter assembly provided with a wire arranged therein to form a loop extending from near the effective end of the catheter for (by)passing an occlusion in a vein/artery. This loop consists of two wire ends, one of which wire ends extends through the catheter to the control end thereof, while the other wire end is attached thereto, in close proximity to the effective end of the catheter. By varying the relative position of the loop wire end extending from the control end and said control end, the size of the loop and the pushability thereof at the effective end of the catheter can be determined. In this manner, the occlusion can be removed with precise control by the physician using two hands. In addition, the catheter according to the invention is formed not only for the loop wire end extending through the catheter, but also for incorporating a guide wire and/or for contrast fluids.
Abstract:
A cardiovascular prosthetic valve, the valve comprising an inflatable cuff comprising at least one inflatable channel that forms, at least in part, an inflatable structure, and a valve coupled to the inflatable cuff, the valve configured to permit flow in a first axial direction and to inhibit flow in a second axial direction opposite to the first axial direction, the valve comprising a plurality of tissue supports that extend generally in the axial direction and that are flexible and/or movable throughout a range in a radial direction.
