Delivery systems are used for medical devices. For example, this document describes delivery systems for implantable medical devices such as, but not limited to, prosthetic heart valves that are deliverable in a minimally invasive manner using a system of catheters. The delivery systems may include a valve stop member that establishes the longitudinal position of the prosthetic heart valve on a balloon member. Such a valve stop member can be constructed as a braided wire body or cellular body to provide multiple advantages.

Medical device delivery systems

A catheter and a method of making a device having an outer member, a primer, and an inner liner laminated to the outer member. The primer is provided between the outer member and the inner liner and annealed to secure the inner liner to the outer member.

Catheter having a laminated polytetrafluoroethylene liner and method of manufacture

A system for drawing blood from a heart of a patient, includes a blood pump, an outflow cannula and a flexible cannula assembly. The cannula assembly further includes a flexible cannula body including a proximal end, a distal end, an inner wall defining a lumen, and an outer wall. A tip is coupled with the distal end of the cannula body, and an anchor is coupled to the tip. The anchor is configured to engage an internal structure of the heart and resists movement of the cannula assembly in at least one direction along the flexible cannula body. A ring member is configured to be coupled to the heart wall and is positioned at least partially around the outer wall of the cannula body proximally relative to the tip. The ring member is further configured to provide hemostasis between the heart wall and the cannula body.

Heart assist system and methods

A cannula assembly for directing blood from the heart of a patient and a minimally invasive method of implanting the same. The cannula assembly includes a flexible cannula body having a proximal end and a distal end with a receiving portion, and a transseptal tip having a distal end and a proximal end with an engaging portion. First and second anchors are coupled to the transseptal tip and configured to be deployed from a contracted state to an expanded state. The engaging portion of the transseptal tip is operable to removably engage the receiving portion of the flexible cannula body in vivo.

Two-piece transseptal cannula, delivery system, and method of delivery

A cannula assembly, further comprising a cannula body for directing blood from the heart of a patient, having distal and proximal ends and a lumen therebetween. A tip coupled to the distal end of the body, the tip having an opening. A pump for drawing blood into the cannula assembly and dispensing the blood from the cannula assembly and into the patient circulatory system. The lumen of the cannula body further comprises a first inner diameter at the proximal end and a second inner diameter at the distal end, the first inner diameter being larger than the second inner diameter. A tapered portion defined as a decrease in inner diameter from the first inner diameter to the second inner diameter between the proximal and distal ends, the tapered portion configured to prevent cavitation of the blood within the cannula.

Transseptal cannula, tip, delivery system, and method

Spinal stabilization devices for addressing back pain originating in the facet joints and the spinous processes of the vertebrae. One embodiment of the present invention includes a substantially T-shaped facet implant for insertion between the facets of two successive vertebrae after a desired amount of the articulating surfaces have been resected. The long and flat portion of the T-shaped facet implant is inserted in between the facets and then the wings of the T-shape, also called fixation tabs, are secured to the spine to secure the facet implant into place. The T-shape implant may also be a part of a spinal stabilization system that includes a facet implant, a spinous process spacer, and a flexible connecting member securing the same.

Facet replacement/spacing and flexible spinal stabilization

A method of thermally treating tissue during a surgical procedure where a surgical access device, including a body member having walls with at least one conduit therein, is inserted into the patient. A chilled fluid is circulated through the at least one conduit such that the tissue that is located proximate the body member is cooled. Alternatively, the body member may be constructed from a highly thermally conductive material such that heat energy is transmitted through the body from the tissue located proximate the body member and into a heat sink. The surgical device may include a first or second blade portions constructed from an inner and an outer shell having walls. Ribs located on the inner shell sealingly coupled to the inner wall of the outer shell to create the at least one conduit within the walls of the blade portion.

Surgical access system and method of using the same

An expandable surgical site access system and method for using the expandable surgical site access system to perform minimally invasive, percutaneous surgeries to access the spine or other bone structures, organs, or locations of the body is disclosed. In one embodiment, the surgical site access system includes an elongated, expandable stent that is particularly adapted to be deployed in a body during a surgical procedure to provide access to a surgical site within the body. The stent defines a working channel through the body from a point of entry to the surgical site.

Surgical site access system and deployment device for same

A transseptal cannula assembly for directing blood from the heart of a patient and a minimally invasive method of implanting the same. The transseptal cannula assembly includes a flexible cannula body having proximal and distal portions with a lumen therebetween, a tip coupled to the distal portion of the flexible cannula body, and first and second anchors coupled to the tip. The anchors can be configured to be deployed from a contracted state to an expanded state and are configured to engage opposite sides of the heart tissue when in the expanded state. The anchors resist movement of the cannula assembly along a lengthwise central axis of the flexible cannula body.

Methods of securing a cannula assembly, implanting a circulatory assist system and crossing a tissue barrier

The present invention relates to flexible members for stabilizing a spinal column and methods for making the flexible members. In one embodiment, a flexible member comprises an inner elastomeric member and an outer fabric layer situated securely around the inner elastomeric member. The inner elastomeric member has a first elasticity to provide the flexible member with a desired flexibility. In another embodiment, the flexible member includes an outer covering that defines an outer elastomeric member. The outer elastomeric member may be situated securely around the outer fabric layer with the inner elastomeric member, the outer fabric layer, and the outer elastomeric member having the common lengthwise axis and defining the body including the opposing first and second ends. The outer elastomeric member may have a second elasticity that is less than the first elasticity.
