摘要： A suturing device for suturing a portion of biological tissue includes a needle attached to a suture, a needle holder that releasably holds the needle, and a needle driver adapted to be advanced and retracted substantially parallel to a longitudinal axis of the suturing device. A distal needle holder adapted to releasably hold the needle is positioned in a distal position relative to the portion of biological tissue and a distal end of the needle driver is positioned in a proximal position relative to the portion of biological tissue. The needle is positioned in either the proximal position or the distal position. The needle driver is moved longitudinally in a first direction along a path substantially parallel to the longitudinal axis such that the needle and suture pass through the portion of biological tissue, thereby forming a suture incision through which the suture passes. By repeating the above-described processes, a series of stitches is thereby formed.

摘要： A state machine circuit may be used to control a multiplexing circuit that selects and provides respective ones of multiple input clock signals to a clock-synthesizing circuit that generates a synthesized clock signal in response to such input clock signals. The state machine circuit may, for example, be configured so that the synthesized clock signal is a spread-spectrum clock signal and/or a clock signal having a nominal frequency that is greater than a nominal frequency of each of the input clock signals.

摘要： Methods and apparatus are provided for closing incisions within biological tissue. In one embodiment, a device and method are provided for suturing biological tissue, such as, for example, an organ or blood vessel. The suturing apparatus is particularly well suited for suturing an incision made in an artery, such as the femoral artery, following a catheterization procedure. The device eliminates the need to apply pressure to a patient's thigh for an extended period of time, and eliminates many of the complications and costs associated with the creation of a thrombus patch. In addition, the device comprises an improved handle portion which enables the physician to quickly and easily apply suture. The handle portion is very reliable and easy to manipulate. The suturing may be used in combination with existing catheter sheath introducers.

摘要： A suturing apparatus comprises an elongated body, at least one arms movable relative to the elongated body and at least one needle movable relative to the elongated body. The arm releasably holds an end portion of a length of suture. The arm has a sharp end portion adapted to pierce an inner surface of a wall of a biological structure and pass an end portion of the suture through the inner surface. The needle is adapted to pierce the inner surface of such biological structure at a location proximal to the location where the end portion of the suture was inserted. The needle captures an end portion of the suture from the arm and draws the end portion of the suture back through the inner surface. The end of the suture is then drawn out of the biological structure by removing the elongated body.

摘要： Previously available analog domain decimation techniques are limited to simple equally-weighted averaging of photosite outputs. Decimation of a Bayer pattern image by an even-factor, such as by two or six, using simple equally-weighted averaging of photosite outputs in the analog domain results in effective sampling locations that are unevenly spaced apart. Standard interpolation of the unevenly spaced effective sampling locations generates image artifacts that reduce the quality of the reconstructed image in the smaller format because standard interpolation methods assume that the effective sampling locations are evenly spaced. Implementations of systems, methods and apparatus disclosed herein aim to produce substantially evenly spaced effective sampling locations in the analog domain. More specifically, in some implementations, the unequally-weighted-average even-factor decimation methods disclosed herein produce substantially more evenly spaced effective sampling locations as compared to the equally-weighted-average even-factor decimation processes previously used in the analog domain.
摘要翻译： 先前可用的模拟域抽取技术仅限于对光电子输出进行简单的等效加权平均。 通过使用模拟域中的光电子输出的简单的等份加权平均，通过偶数因子（例如2或6）抽取拜耳图案图像导致不均匀间隔开的有效采样位置。 不均匀间隔的有效采样位置的标准插值产生图像伪影，其以更小的格式降低重建图像的质量，因为标准插值方法假设有效采样位置是均匀间隔的。 本文公开的系统，方法和装置的实现旨在在模拟域中产生基本上均匀间隔的有效采样位置。 更具体地说，在一些实施方案中，与先前在模拟域中使用的均等加权平均偶数因子抽取处理相比，本文公开的不平等加权平均偶数抽取方法产生了更均匀间隔的有效采样位置。
