Biopsy instrument

The present disclosure is directed to a medical implant () comprising: &#x2014;a coil-shaped component () and &#x2014;a first mesh component () and a second mesh component (); wherein each mesh component has a largest surface extending in two directions in the x-y plane of the mesh component, and wherein each mesh component has a projected area, which is said largest surface as projected in the x-y plane of the medical implant; wherein the coil-shaped component is arranged between the two mesh components; wherein the coil-shaped component has a center core which is hollow; and wherein the coil-shaped component has a helix rotation axis, which extends in parallel with said projected area of the first mesh component and said projected area of the second mesh component.

Medical implant for regeneration of tissue

The invention relates to a resorbable multifilament comprising a number of individual resorbable filaments of a first type having a first degradation time and a number of individual resorbable filaments of a second type having a second degradation time, wherein the filaments of the first type and the filaments of the second type are arranged in close relationship to form a composite multifilament having a length and a specific composite cross-section comprising cross-sections of the individual filaments of the first type and second type, wherein the cross-sections of the individual filaments of the first and second type are located at determined relative positions, wherein the relative positions amongst the individual cross-sections of the filaments of the first and second types are invariant over the length of the composite multifilament.

The invention relates to a sensor and guide wire assembly () for intravascular measurements of physiological variables in a living body, comprising a core wire (), a first coil (), a jacket (), and a second coil (). The jacket () comprises a first end portion (), which is crimped onto the core wire () and over which a portion of the first coil () is threaded, and a second end portion (), which is crimped onto the core wire () and over which a portion of the second coil () is threaded.

Sensor and guide wire assembly

The invention provides a method for replacing a first introducer, whose distal end is inside a vessel and whose proximal end is outside the skin of a patient, with a second introducer. The method comprises the steps of inserting a guide rod into the first introducer, removing the first introducer, passing the second introducer over the guide rod, and removing the guide rod. The guide rod to be used according to the method has preferably a flexible distal portion with a blunt distal end and a stiff proximal portion with a tapered proximal end.

A closure device includes an actuator movable between an initial extended position, a first position, and a second position with respect to a housing of the closure device, an inner seal configured to deploy from a distal end of the closure device when the actuator shifts from the initial extended position to the first position, a biasing mechanism configured to urge the actuator from the first position to the second position when a first pulling force is applied to the housing, and a locking member configured to deploy from the distal end of the closure device when the actuator shifts from the second position to the first position subsequent to deployment of the inner seal.

Closure device and method for sealing a puncture in a blood vessel

A tool () is provided for inserting and mating two plug members () of a sealing device () for closing a wound in the wall of a vessel by placing the distal plug member () of the sealing device inside the vessel and the proximal plug member () on the outside of the vessel. The distal plug member is provided with an elongated retracting means () extending from the distal plug member. The tool comprises a gear mechanism () coupled to the retracting means for converting a movement of the tool in a proximal direction away from the wound (), when the distal plug member is anchored in the vessel (), to a pushing movement for moving the proximal plug member in a direction towards the distal plug member in response to a stretching force in the retracting means.

Tool, a sealing device, a system and a method for closing a wound

A device having an inner seal and a retaining assembly seals a puncture in a blood vessel. The inner seal is placed inside the blood vessel and seals the puncture by contacting the inner surface wall of the blood vessel. The retaining assembly has at least two loops which engage the inner seal. Each loop may remain in substantial contact with the inner seal for substantially 360 degrees of the travel of each loop. The at least two loops may lie in a plane which is parallel to both the major axis of the inner seal and a folding axis. A locking member may be slid along the retaining assembly so as to contact the outer surface wall of the blood vessel.

Absorbable medical sealing device with retaining assembly having at least two loops

The invention provides an introducer sheath (), whose distal end is to be positioned inside a vessel (), at a predetermined distance from the wall () of the vessel (). The introducer sheath () comprises a distal portion () with a first diameter and a proximal portion () with a second diameter, the first diameter being smaller than the diameter of the puncture hole and the second diameter being larger than the diameter of the puncture hole.

Introducer sheath

A closure device for sealing a percutaneous puncture in the wall of a blood vessel includes: an insertion tool having an actuator which is operable in a first mode in which the actuator is configured for deployment of an inner seal inside the vessel and operable in a second mode in which the actuator is configured for tamping a locking member on an outside of the vessel, where the actuator is arranged to be set into the second mode in response to a pulling force acting on a filament connecting the inner seal and the locking member.

A medical sealing device for the sealing of a puncture hole in a vessel wall includes an inner member, which is adapted to be positioned at an interior surface of the vessel wall, and an outer member, which is adapted to be positioned outside the vessel wall, the inner member and the outer member being held together by a retaining member. The sealing device further includes a sealing element, which is adapted to be positioned between the vessel wall and the outer member to improve the sealing performance of the sealing device.

Medical sealing device

The invention provides a puncturing guide () for guiding a puncturing needle into a target site within the body of a patient. The puncturing guide () comprises a base plate (), a needle guide (), a retainer () for securing the needle guide () to the base plate (), a first segment () of a first semi-sphere, a second segment () of a second semi-sphere, and a needle guide () attached to the second segment (). During a positioning operation, the second segment () slides on the first segment (), so that the needle guide () is movable around the center of the first semi-sphere, which is in level with the underside of the base plate (), thereby providing the possibility to position the tip of a puncturing needle at a puncturing point on the patient's skin and then, in a separate operation, set the entrance angle of the puncturing needle without changing its entrance point.

Guide for a medical device

An indicator device for visually indicating a pressure of blood inside a blood vessel includes: a body, the body comprising a duct extending in the body and having a sealed proximal end; a distal end portion adapted to be positioned inside the blood vessel and including a liquid inlet opening in fluid communication with the duct; and a window including an at least semi-transparent section configured to enable visual observation of blood entering into the duct via the inlet opening when the inlet opening is located inside the blood vessel.
